TY - THES A1 - Zürn, Michael T1 - The Dual Nature of Utility - Categorical and Comparative Evaluations in Economic Decisions T1 - Die Dualität des Nutzens - kategoriale und komparative Bewertungen in ökonomischen Entscheidungen N2 - Utility is perhaps the most central concept in modern economic theorizing. However, the behaviorist reduction to Revealed Preference not only removed the psychological content of utility but experimental investigations also exposed numerous anomalies in this theory. This program of research focused on the psychological processes by which utility judgments are generated. For this purpose, the standard assumption of a homogeneous concept is substituted by the Utilitarian Duality Hypothesis. In particular, judgments concerning categorical utility (uCat) infer an object's category based on its attributes which may subsequently allow the transfer of evaluative information like feelings or attitudes. In contrast, comparative utility (uCom) depends on the distance to a reference value on a specific dimension of comparison. Importantly, dimensions of comparison are manifold and context dependent. In a series of experiments, we show that the resulting Dual Utility Model is able to explain several known anomalies in a parsimonious fashion. Moreover, we identify central factors determining the relative weight assigned to both utility components. Finally, we discuss the implications of the Utilitarian Duality for both, the experimental practice in economics as well as the consequences for economic theorizing. In sum, we propose that the Dual Utility Model can serve as an integrative framework for both the rational model and its anomalies. N2 - Der Nutzen ist wohl eines der meist beachteten Konzepte der ökonomischen Theorie. Allerdings entfernte die behavioristische Reduktion auf offenbarte Präferenzen nicht nur den psychologischen Inhalt des Nutzens, sondern zeigte darüber hinaus in experimentellen Untersuchungen auch zahlreiche Anomalien der Theorie auf. Das vorliegende Forschungsprogramm stellt die psychologischen Prozesse in den Vordergrund, mittels derer Nutzen beurteilt wird. Zu diesem Zweck wird die verbreitete Annahme eines homogenen Konzepts durch die Zwei-Nutzen-Hypothese ersetzt. Im Besonderen bestimmen Urteile über den kategorialen Nutzen (uCat) anhand der Attribute eines Objekts zunächst dessen Kategorie, wodurch daraufhin bewertende Informationen, wie z.B. Gefühle oder Einstellungen, auf das Objekt übertragen werden können. Demgegenüber bestimmt sich der komparative Nutzen (uCom) über die Abweichung von einem Referenzwert in einer bestimmten Vergleichsdimension, welche generell zahlreich und kontextabhängig sein können. In einer Serie von Experimenten wird gezeigt, dass das resultierende Zwei-Nutzen-Modell eine Reihe von bekannten Anomalien in einer sparsamen Weise erklären kann. Darüber hinaus werden zentrale Faktoren identifiziert, welche die relative Gewichtung beider Nutzenkomponenten bestimmen. Schließlich werden die Implikationen der Zwei-Nutzen-Hypothese für die experimentelle Praxis und die ökonomische Theorie diskutiert. Zusammenfassend wird ausgeführt, dass das entwickelte Zwei-Nutzen-Modell als integrativer Rahmen für sowohl das rationale Modell als auch für seine Anomalien dienen kann.

In two longitudinal studies differences in phonological sensitivity among children before learning to read (at age 6 to 7) were tested with versions of Bradley & Bryant's (1985) oddity detection task. Children's reading and spelling achievements were tested about one year later at the end of grade one, and again at around the age of 10. The main finding was a developmental change in the predictive relationship of rhyme and word-onset awareness. Rhyme awareness was only minimally predictive for reading and spelling achievement at the end of grade one, but gained substantially in predictive importance for reading and spelling achievement in grades three and four. No such predictive improvement was observed for word-onset awareness. It is proposed that rhyme awareness is initially of little importance, because in the first phase of learning to read German children rely heavily on indirect word recognition via grapheme--phoneme translation and blending. The gain in the predictive importance of rhyme awareness is explained by its helpful effect on the establishment of mental representations of written words. Such mental representations allow fast, direct word recognition and orthographically correct spellings. A wareness of larger phonological units is helpful for the efficient establishment of such representations, by allowing connections of recurring grapheme clusters in written words with phonology.

A1 - Brosch, Tobias T1 - Faces in context: A review and systematization of contextual influences on affective face processing N2 - Facial expressions are of eminent importance for social interaction as they convey information about other individuals’ emotions and social intentions. According to the predominant “basic emotion” approach, the perception of emotion in faces is based on the rapid, auto- matic categorization of prototypical, universal expressions. Consequently, the perception of facial expressions has typically been investigated using isolated, de-contextualized, static pictures of facial expressions that maximize the distinction between categories. However, in everyday life, an individual’s face is not perceived in isolation, but almost always appears within a situational context, which may arise from other people, the physical environment surrounding the face, as well as multichannel information from the sender. Furthermore, situational context may be provided by the perceiver, including already present social infor- mation gained from affective learning and implicit processing biases such as race bias.Thus, the perception of facial expressions is presumably always influenced by contextual vari- ables. In this comprehensive review, we aim at (1) systematizing the contextual variables that may influence the perception of facial expressions and (2) summarizing experimental paradigms and findings that have been used to investigate these influences. The studies reviewed here demonstrate that perception and neural processing of facial expressions are substantially modified by contextual information, including verbal, visual, and auditory information presented together with the face as well as knowledge or processing biases already present in the observer. These findings further challenge the assumption of auto- matic, hardwired categorical emotion extraction mechanisms predicted by basic emotion theories. Taking into account a recent model on face processing, we discuss where and when these different contextual influences may take place, thus outlining potential avenues in future research.

T1 - Social and nonsocial open field behaviour of rats under light and noise stimulation N2 - ln two experiments, male rats were observed in pairs under different environmental stimulations in an open field. ln Experiment 1, white noise of 85 dB(A) reduced social activities and increased defecation compared to 75 dB(A) and 65 dß(A). ln Experiment 2, the illumination of the open field was varied in addition to a variation of the noise intensity. Again, 85 dB(A) as compared to 50 dB(A) reduced social activities and increased defecation, but also led to changes in non-social behaviours such as sniffing, grooming, and rearing. ln contrast, 400 lx did not differ substantially in its effects from 40 lx in any of the observed behavioural categories. Altogether, the behaviour pattern under 85 dß(A) white noise cannot satisfactorily be explained only by increased anxiety or fear. Alternative explanations are discussed.

Although they have been topic of research for more than 20 years and were multiply proven to be a reliable communication method, BCIs are almost exclusively used in experimental settings, handled by qualified experts. This study investigates if ERP–BCIs can be handled independently by laymen without expert support, which is inevitable for establishing BCIs in end-user’s daily life situations. Furthermore we compared the classic character-by-character text entry against a predictive text entry (PTE) that directly incorporates predictive text into the character- matrix. N = 19 BCI novices handled a user-centered ERP–BCI application on their own without expert support. The software individually adjusted classifier weights and control parameters in the background, invisible to the user (auto-calibration). All participants were able to operate the software on their own and to twice correctly spell a sentence with the auto-calibrated classifier (once with PTE, once without). Our PTE increased spelling speed and, importantly, did not reduce accuracy. In sum, this study demonstrates feasi- bility of auto-calibrating ERP–BCI use, independently by laymen and the strong benefit of integrating predictive text directly into the character-matrix.

In particular, it is assumed that social behavior is controlled by 2 interacting systems that follow different operating principles. The reflective system generates behavioral decisions that are based on knowledge about facts and values, whereas the impulsive system elicits behavior through associative links and motivational orientations. The proposed model describes how the 2 systems interact at various stages of processing, and how their outputs may determine behavior in a synergistic or antagonistic fashion. It extends previous models by integrating motivational components that allow more precise predictions of behavior. The implications of this reflective–impulsive model are applied to various phenomena from social psychology and beyond. Extending previous dual-process accounts, this model is not limited to specific domains of mental functioning and attempts to integrate cognitive, motivational, and behavioral mechanisms.

The younger children recalled significantly more items under sort-and-remember than under play-and-remember instructions, whereas no significant recall differences between instructional conditions were found for the older children. However, 6-year-olds showed higher levels of recall than 4-year-olds in both instructional conditions. Category cues were much more effective than color cues, regardless of age. In addition, clustering scores indicated that conceptual organization at both encoding and retrieval increased with age and with instruction. These results show that from 4 to 6 years of age children are learning to spontaneously employ memory strategies. In addition, they highlight the increasing importance of conceptual organization to retention of young children. Finally, the metamemory data suggest that there may be a lag between children’s articulated declarative knowledge about the usefulness of conceptual organization and their procedural use of it.

Ghildren could fool a competitor by hiding targets in locations that were labeled with semantically weakly associated cues and help a cooperative partner by hiding them in semantically highly associated locations. Very few 4-year-olds, half the 5-year-olds, and almost all 6-year-olds appropriately chose semantically highly vs. weakly associated hiding places to make the targets easy vs. difficult to find. The second experiment showed that 4-year-olds did not strategically manipulate cues as sources of information, although they themselves proficiently used them as such in a search task. These findings are discussed with regard to research on children's developing understanding of origins of knowledge and belief and with regard to recent claims that young preschoolers possess a metacognitive understanding of cognitive cuing.

T1 - Children’s Sleep Comic: development of a new diagnostic tool for children with sleep disorders [original research] N2 - Background: A solid diagnosis of sleep disorders in children should include both self-ratings and parent ratings. However, there are few standardized self-assessment instruments to meet this need. The Children’s Sleep Comic is an adapted version of the unpublished German questionnaire “Freiburger Kinderschlafcomic” and provides pictures for items and responses. Because the drawings were outdated and allowed only for qualitative analysis, we revised the comic, tested its applicability in a target sample, and suggest a procedure for quantitative analysis. Methods: All items were updated and pictures were newly drawn. We used a sample of 201 children aged 5–10 years to test the applicability of the Children’s Sleep Comic in young children and to run a preliminary analysis. Results: The Children’s Sleep Comic comprises 37 items covering relevant aspects of sleep disorders in children. Application took on average 30 minutes. The procedure was well accepted by the children, as reflected by the absence of any dropouts. First comparisons with established questionnaires indicated moderate correlations. Conclusion: The Children’s Sleep Comic is appropriate for screening sleep behavior and sleep problems in children. The interactive procedure can foster a good relationship between the investigator and the child, and thus establish the basis for successful intervention if necessary.

Inhibitory control, defined as the ability to suppress inappropriate responses (Verbruggen & Logan, 2008), is essential for adaptable and goal-oriented behavior. The rapid and non-linear development of this cognitive function in early childhood presents unique challenges for accurate assessment. As children age, they often exhibit a ceiling effect in terms of response accuracy (Petersen et al., 2016), underscoring the need to consider response latency as well. Ideally, combining response latency with accuracy could yield a more precise measure of inhibitory control (e.g., Magnus et al., 2019), facilitating a detailed tracking of developmental changes in inhibitory control across a wider age spectrum. The three studies of this dissertation collectively aim to clarify the relationship between response accuracy, response latency, and inhibitory control across different stages of child development. Each study utilizes a computerized Pointing Stroop Task (Berger et al., 2000) to measure inhibitory control, examining the task's validity and the integration of dual metrics for a more comprehensive evaluation. The first study focuses on establishing the validity of using both response accuracy and latency as indicators of inhibitory control. Utilizing the framework of explanatory item-response modeling (De Boeck & Wilson, 2004), the study revealed how the task characteristics congruency and item position influence both the difficulty level and timing aspects in young children’s responses in the computerized Pointing Stroop task. Further, this study found that integrating response accuracy with latency, even in a basic manner, provides additional insights. Building upon these findings, the second study investigates the nuances of integrating response accuracy and latency, examining whether this approach can account for age-related differences in inhibitory control. It also explores whether response latencies may contain different information depending on the age and proficiency of the children. The study leverages novel and established methodological perspectives to integrate response accuracy and latency into a single metric, showing the potential applicability of different approaches for assessing inhibitory control development. The third study extends the investigation to a longitudinal perspective, exploring the dynamic relationship between response accuracy, latency, and inhibitory control over time. It assesses whether children who achieve high accuracy at an earlier age show faster improvement in response latency, suggesting a non-linear maturation pathway of inhibitory control. The study also examines if the predictive value of early response latency for later fluid intelligence is dependent on the response accuracy level. Together, these empirical studies contribute to a more robust understanding of the complex interaction between inhibitory control, response accuracy, and response latency, facilitating valid evaluations of cognitive capabilities in children. Moreover, the findings may have practical implications for designing educational strategies and clinical interventions that address the developmental trajectory of inhibitory control. The nuanced approach advocated in this dissertation suggests prioritizing accuracy in assessment and interventions during the early stages of children's cognitive development, gradually shifting the focus to response latency as children mature and secure their inhibitory control abilities. N2 - Die vorliegende Dissertation erforscht die Erfassung und Entwicklung von Inhibitionskontrolle bei jungen Kindern – einer zentralen Komponente der Exekutiven Funktionen. Inhibitionskontrolle, also die Fähigkeit, automatisierte aber unangemessene Reaktionen zu unterdrücken (Verbruggen & Logan, 2008), ist wesentlich für adaptives und zielgerichtetes Verhalten. Die schnelle und nichtlineare Entwicklung dieser kognitiven Funktion im frühen Kindesalter gestaltet eine präzise Messung herausfordernd. Mit zunehmendem Alter der Kinder zeigt sich häufig ein Deckeneffekt hinsichtlich der Antwortgenauigkeit (Petersen et al., 2016), was die Notwendigkeit hervorhebt, auch die Reaktionszeit in Betracht zu ziehen. Idealerweise könnte durch die Integration von Reaktionszeit und Antwortgenauigkeit ein Messwert berechnet werden (z.B. Magnus et al., 2019), welcher eine detaillierte Erfassung von Entwicklungsveränderungen der Inhibitionskontrolle über ein breiteres Altersspektrum hinweg ermöglicht. Die drei Studien dieser Dissertation zielen darauf ab, die Beziehung zwischen Antwortgenauigkeit, Reaktionszeit und Inhibitionskontrolle in verschiedenen Stadien der kindlichen Entwicklung zu untersuchen. Jede Studie nutzt eine computergestützte Inhibitionsaufgabe, den computerized Pointing-Stroop Task (cPST; Berger et al., 2000), um die Inhibitionskontrolle zu messen, wobei die Validität dieses Tests und die Integration von Antwortgenauigkeit und Reaktionszeit für eine umfassendere Bewertung untersucht werden. In der ersten Studie wird untersucht, ob sowohl Antwortgenauigkeit als auch Reaktionszeit valide Indikatoren für Inhibitionskontrolle in jungen Kindern darstellen. Unter Verwendung von explanatorischen Item-Response-Modellen zeigte die Studie, wie die Aufgabenmerkmale Kongruenz und Item-Position die Aufgabenschwierigkeit sowohl in Bezug auf Antwortgenauigkeit als auch Reaktionszeit im cPST beeinflussen. Darüber hinaus zeigten sich erste Hinweise, dass bereits eine rudimentäre Integration von Antwortgenauigkeit und Reaktionszeit zusätzliche Einsichten liefert. Aufbauend auf diesen Erkenntnissen untersucht die zweite Studie die Feinheiten der Integration von Antwortgenauigkeit und Reaktionszeit und prüft, ob moderne Methoden der Integration dieser beiden Metriken altersbedingte Unterschiede in der Inhibitionskontrolle berücksichtigen können. Sie erforscht auch, ob sich aus den Reaktionszeiten in Inhibitionsaufgaben, abhängig vom Alter und Können der Kinder, unterschiedliche Schlussfolgerungen ziehen lassen. Die Studie nutzt neue und etablierte methodische Ansätze, um Antwortgenauigkeit und Reaktionszeit zu einer Metrik zu integrieren und zeigt die potenzielle Anwendbarkeit verschiedener Ansätze zur Bewertung der Entwicklung der Inhibitionskontrolle. Die dritte Studie erweitert die Untersuchung auf eine Längsschnittperspektive und erforscht die dynamische Beziehung zwischen Antwortgenauigkeit, Reaktionszeit und Inhibitionskontrolle im Laufe der Entwicklung. Sie betrachtet, ob Kinder, die in jüngerem Alter eine hohe Genauigkeit erreichen, eine schnellere Verbesserung in der Reaktionszeit zeigen. Die Studie untersucht weiter, ob der prädiktive Wert von Reaktionszeit für zukünftige fluide Intelligenz in Abhängigkeit zu der Antwortgenauigkeit steht. Zusammen tragen diese empirischen Arbeiten zu einem tieferen Verständnis der komplexen Interaktion zwischen Inhibitionskontrolle, Antwortgenauigkeit und Reaktionszeit bei und erleichtern valide Bewertungen dieser kognitiven Fähigkeiten bei Kindern. Darüber hinaus könnten die Ergebnisse praktische Implikationen für die Gestaltung von Interventionen haben, die sich mit dem Entwicklungsverlauf der Inhibitionskontrolle befassen. Der in dieser Dissertation vertretene Ansatz legt nahe, Antwortgenauigkeit bei der Bewertung und Interventionen während der frühen Phasen der kognitiven Entwicklung von Kindern zu priorisieren und den Fokus allmählich auf die Reaktionszeit zu verlagern, sobald Kinder ihre Inhibitionskontrolle festigen und ausbauen.

Eight experiments investigated their respective influence on evaluative judgments in the domain of stereotyping. Valence of stereotypic information and consistency-driven fluency were manipulated in an impression formation paradigm. When information about the to-be-evaluated target person was strongly valenced, no effects of consistency-driven fluency were observed. Higher cognitive processes, valence of inconsistent attributes, processing priority of category information, and impression formation instructions were ruled out as possible factors responsible for the non-occurrence of fluency effects. However, consistency-driven fluency did influence the evaluative judgment, if the information about a target person was not strongly valenced. It is therefore concluded that both stimulus valence and consistency-driven processing fluency play a role in evaluative judgments in the domain of stereotyping. The respective impact of stimulus valence is much stronger than the impact of unspecific processing dynamics, however. Implications for fluency research and the applied field of stereotype change are discussed. N2 - Sowohl Stimulusvalenz als auch unspezifische Verarbeitungsflüssigkeit können evaluative Urteile beeinflussen. In acht Experimenten wurde ihr relativer Einfluss im Stereotypkontext untersucht. Hierzu wurden in einem Eindrucksbildungsparadigma die Valenz von stereotypisierender Information und die konsistenzbasierte Verarbeitungsflüssigkeit manipuliert. Im Falle starker Stimulusvalenz der Information über die zu bewertende Person hatte konsistenzbasierte Verarbeitungsflüssigkeit keinen Einfluss auf das evaluative Urteil. Höhere kognitive Prozesse, Valenz der inkonsistenten Eigenschaften, Dominanz von kategorialer Information und Eindrucksbildungsinstruktionen konnten als mögliche Erklärungen für das Ausbleiben von Effekten der Verarbeitungsflüssigkeit ausgeschlossen werden. Konsistenzbasierte Verarbeitungsflüssigkeit hatte allerdings einen Einfluss auf evaluative Urteile, wenn Stimuli keine starke Wertigkeit aufwiesen. Daraus wird geschlossen, dass sowohl Stimulusvalenz als auch unspezifische Verarbeitungsflüssigkeit bei evaluativen Urteilen im Stereotypkontext eine Rolle spielen. Der relative Einfluss von Stimulusvalenz ist jedoch deutlich stärker als der Einfluss von Verarbeitungsflüssigkeit. Implikationen für Theorien der Verarbeitungsflüssigkeit und für die Anwendung im Bereich der Stereotypveränderung werden diskutiert.

This finding is not consistent with the results of a study by Istomina (1975), conducted in 1948, leading to the concJusion that (a) preschoolers do not use voluntary remembering, and (b) children generally recall better in play situations than in typical experimental settings. In this study, two experiments were conducted to replicate Istomina's research. In the first, it was shown that Istomina's findings were replicable when methodological problems in the procedure were ignored. Experiment 2 improved methodologically upon Istomina's experimental methods and did not produce results to support her concJusions. Four- and 6-year-olds showed voluntary memory in play activities as weH as in laboratory-type settings, and remembered equally weB in both contexts. The results did not support the assumption that memory performance in young children can be substantially facilitated by motivating contexts.

T1 - Expertise, aptitude, and strategic remembering N2 - Second- and fourth-grade children were classified according to their knowledge of soccer (experts vs. novices) and IQ (high vs. low), and given 2 sort-recall tasks. One task included items related to the game of soccer and the other included items from familiar natural language categories. Previous research has shown that expertise in a snbject can compensate for low levels of performance on text comprehension tasks. Our results, the flrst examing the effects of both expertise and intelligence on a strategic memory task, were that soccer expert children recalled more items on the soccer list bnt not on the nonsoccer list than soccer novice children. However, soccer expertise did not modify a significant effect of IQ level, with high-IQ children recalling more than low-IQ children for all contrasts. Interest in soccer was found to be related to expertise but did not contribute to differences in memory performance. The results demonstrate that the knowledge base plays an important role in children's memory, but that domain knowledge cannot fully eliminate the effects of IQ on sort-recall tasks using domain-related materials. That is, although rich domain knowledge seemed to compensate for low aptitude, in that low-aptitude experts performed at the level of high-aptitude novices, its effects were not strong enough to eliminate performance differences between highand low-aptitude soccer experts.

Strategy use in the task was rated by the experimenter and also assessed via self reports. General and task-related strategy knowledge tmetamemoryt was also examined. Second graders displayed more category clustering during recall for highly associated items than for weakly associated items. whereas older children’s recall organization (but not recall) was unaffected by this organizational dimension. Correlations among measures of metamemory and organizational behavior indicated that second graders in general were unaware of the importance of categorization strategies for facilitation of recall. On the other hand. sorting during study and task-related metamemory were the most important predictors of fourth graders’ recall performance, thus indicating that most fourth graders used categorization strategies deliberately.

To accomplish this goal, three approaches were adopted: First, an overview and systematic comparison of integrity tests was conducted with reference to the construction and application of the tests. Second, the nomological network of integrity tests was expanded with reference to honesty-humility and organizational citizenship behavior at their factor and facet level. Third, two promising methods to reduce faking on integrity tests were tested: the double rating method (Hui, 2001) and the indirect questioning technique. In line with previous research, the results of the overview and comparison of integrity measures confirmed that integrity tests are multidimensional and heterogenous. A clear definition of integrity is urgently needed. The personality trait of honesty-humility and its facets of fairness, and modesty revealed the most significant relationships to integrity. Moreover, organizational citizenship behavior and its facets of altruism, conscientiousness, and sportsmanship were found to significantly relate to integrity. Furthermore, integrity tests were able not only to predict organizational citizenship behavior but also to incrementally predict job performance and organizational citizenship behavior beyond the factor and facet level of the personality traits of conscientiousness and honesty-humility. In contrast to the indirect questioning technique, the double rating method, which includes an other rating and a self rating, was shown to be able to significantly reduce faking on integrity tests in an anonymous survey setting. This dissertation makes an important contribution to better explain the construct and nomological network of integrity, provide a more detailed view on integrity tests and their protection against faking, and expand the predictive and incremental validity of these tests. The implications for future research and practice are further discussed. N2 - Der Fokus dieser Dissertation liegt sowohl auf der Konstrukt- als auch auf der Kriteriumsvalidität von Integritätstests und deren Erhöhung mit Hilfe von drei Ansätzen: (a) Ein Überblick und systematischer Vergleich von Integritätstests mit Bezug auf deren Konstruktion und Anwendung wird erstellt. (b) Das nomologische Netzwerk von Integrität wird erweitert mit Bezug auf Honesty-Humility und freiwilligem Arbeitsverhalten sowohl auf Faktoren- als auch Facettenebene. (c) Zwei vielversprechende Ansätze, um Faking in Integritätstests zu reduzieren, werden getestet: die Doppelte Fragemethode (Hui, 2001) und indirektes Fragen. Im Ergebnis zeigte sich, dass die Multidimensionalität und Heterogenität von Integritätstests bestätigt wurde. Eine klare Definition von Integrität ist dringend notwendig. Mit Blick auf das nomologische Netzwerk zeigte Honesty-Humility und deren Facetten Fairness und Bescheidenheit die höchsten signifikanten Korrelationen mit Integrität. Beim freiwilligen Arbeitsverhalten und deren Facetten Altruismus, Gewissenhaftigkeit und Unkompliziertheit wurden ebenfalls signifikante Zusammenhänge gefunden. Des Weiteren zeigte sich, dass Integritätstests inkrementelle Validität besitzen über die Faktoren und Facetten von Gewissenhaftigkeit und Honesty-Humility hinaus bei der Vorhersage von beruflicher Leistung und bei der Vorhersage von freiwilligem Arbeitsverhalten. Im Hinblick auf die Reduzierung von Faking zeigte nur die Doppelte Fragemethode (d.h. Fremd- und Selbsteinschätzung der Items) in der anonymen Forschungssituation eine signifikante Reduzierung. Diese Dissertation leistet einen wichtigen Beitrag zum besseren Verständnis des Konstruktes und nomologischen Netzwerkes der Integrität, bietet einen detaillierten Einblick in Integritätstests sowie deren Schutz vor Faking und verbessert die prognostische und inkrementelle Validität von Integritätstests.

The results confirmed the findings of previous Monte Carlo studies on clustering procedures in that accuracy was inversely related to coverage, and that algorithms using correlation as the similarity measure were significantly more accurate than those using Euclidean distances. No evidence was found for the assumption that the positive effects of the use of correlation coefficients are confined to unconstrained mixture models.

We direct our gaze at other human beings to see what they are doing and to guess their intentions, but we may also absorb social events en passant as they unfold in the corner of the eye. We use our gaze as a discrete communication channel, sometimes conveying pieces of information which would be difficult to explicate, but we may also find ourselves avoiding eye-contact with others in moments when self-disclosure is fear-laden. We experience our gaze as the most genuine expression of our will, but research also suggests considerable levels of predictability and automaticity in our gaze behavior. The phenomenon’s complexity has hindered researchers from developing a unified framework which can conclusively accommodate all of its aspects, or from even agreeing on the most promising research methodologies. The present work follows a multi-methods approach, taking on several aspects of the phenomenon from various directions. Participants in study 1 viewed dynamic social scenes on a computer screen. Here, low-level physical saliency (i.e. color, contrast, or motion) and human heads both attracted gaze to a similar extent, providing a comparison of two vastly different classes of gaze predictors in direct juxtaposition. In study 2, participants with varying degrees of social anxiety walked in a public train station while their eye movements were tracked. With increasing levels of social anxiety, participants showed a relative avoidance of gaze at near compared to distant people. When replicating the experiment in a laboratory situation with a matched participant group, social anxiety did not modulate gaze behavior, fueling the debate around appropriate experimental designs in the field. Study 3 employed virtual reality (VR) to investigate social gaze in a complex and immersive, but still highly controlled situation. In this situation, participants exhibited a gaze behavior which may be more typical for real-life compared to laboratory situations as they avoided gaze contact with a virtual conspecific unless she gazed at them. This study provided important insights into gaze behavior in virtual social situations, helping to better estimate the possible benefits of this new research approach. Throughout all three experiments, participants showed consistent inter-individual differences in their gaze behavior. However, the present work could not resolve if these differences are linked to psychologically meaningful traits or if they instead have an epiphenomenal character. N2 - Soziale Aufmerksamkeit ist ein allgegenwärtiges, aber auch ein rätselhaftes Phänomen, das mitunter schwierig zu fassen ist. Wir richten unseren Blick auf andere Menschen, um ihr Tun zu verfolgen und um ihre Absichten einzuschätzen, aber manchmal verfolgen wir soziale Ereignisse auch ganz beiläufig aus dem Augenwinkel heraus. Wir setzen unseren Blick als ein eigenes Kommunikationsmedium ein und übertragen mit ihm teilweise Botschaften, die nur schwer zu beschreiben sind, aber wir weichen mitunter dem Blickkontakt mit anderen auch aus, wenn wir Angst davor haben, zu viel von uns preiszugeben. Unser Blick stellt sich für uns als eine ureigene Äußerung unseres Willens dar, aber die Forschung hat auch gezeigt, dass unser Blickverhalten in beträchtlichem Maße vorhersehbar und automatisch abläuft. In der Vielschichtigkeit des Phänomens liegt für Forscher eine Hürde bei dem Versuch, alle seine Aspekte schlüssig in ein umfassendes Bezugssystem einzuordnen, oder sich auch nur auf die vielversprechendsten Forschungsmethoden zu einigen. Die vorliegende Arbeit verbindet den Einsatz unterschiedlicher Methoden, um sich mehreren Aspekten des Phänomens aus verschiedenen Blickrichtungen zu nähern. Die Versuchspersonen in Studie 1 sahen dynamische soziale Szenen, die ihnen auf einem Computerbildschirm dargeboten wurden. Hierbei wurde ihr Blick in ähnlichem Maße von physikalischer Salienz (z.B. Farbe, Kontrast oder Bewegung) angezogen wie von menschlichen Köpfen, wodurch zwei ganz unterschiedliche Gruppen von Prädiktoren für Blickverhalten in direkter Gegenüberstellung verglichen wurden. In Studie 2 bewegten sich Versuchspersonen mit unterschiedlich ausgeprägter sozialer Ängstlichkeit zu Fuß in einem öffentlichen Bahnhof, während ihre Augenbewegungen erfasst wurden. Mit zunehmender sozialer Ängstlichkeit neigten Versuchspersonen dazu, nahe Personen im Gegensatz entfernteren Personen im Verhältnis weniger anzuschauen. Als das Experiment mit einer gematchten Gruppe von Versuchspersonen in einer Laborsituation wiederholt wurde, zeigte sich kein Einfluss der sozialen Ängstlichkeit auf das Blickverhalten, was der Diskussion um angemessene experimentelle Designs in diesem Forschungsbereich einen weiteren Impuls verlieh. In Studie 3 wurde Virtuelle Realität (VR) eingesetzt, um das Blickverhalten in einer komplexen und immersiven, aber dennoch streng kontrollierten Umgebung zu untersuchen. In dieser Situation zeigten Probanden ein Blickverhalten, das eher dem in echten Situationen als dem im Labor entspricht, indem sie direkten Blickkontakt mit einer virtuellen Person mieden, so lange diese sie nicht anschaute. Durch diese Studie konnten wichtige Erkenntnisse über das Blickverhalten in sozialen virtuellen Situationen gewonnen werden, wodurch der mögliche Nutzen dieses neuen Forschungsansatzes besser beurteilt werden kann. In allen drei Experimenten zeigten Versuchspersonen konsistente inter-individuelle Unterschiede in ihrem Blickverhalten. Es konnte jedoch im Rahmen der vorliegenden Arbeit nicht geklärt werden, ob diese Unterschiede psychologisch bedeutsame Eigenschaften oder eher Epiphänomene darstellen.

Placebo and nocebo effects are among the most prominent examples for such manipulations. Placebo and nocebo manipulations cause reliable psychological and physiological changes, although the administered agent or treatment is inert. The present dissertation aimed at investigating the role of cognitive and emotional influences in the generation of placebo and nocebo effects on pain perception. In addition, the feasibility of solely psychological placebo manipulations to alter the perception of pain was tested. Two commonly discussed preconditions for the generation of placebo and nocebo effects are prior experiences (i.e., past encounter of drug effects) and expectations (i.e., positive or negative attitudes towards an intervention). So far, research on placebo and nocebo effects relied on the administration of sham interventions, which resembled medical treatments like inert pills, creams or injections. However, such experimental procedures deal with confounds due to earlier experiences and expectations resulting from the individual’s history with medical interventions. Accordingly, the implementation of a placebo manipulation that is completely new to an individual, seems necessary to disentangle the contribution of experience and expectation for the induction of placebo and nocebo effects. To this end, in Experiment 1 the level of experience and expectation regarding a placebo-nocebo treatment was stepwise manipulated across three different experimental groups. To avoid any resemblances to earlier experiences and individual expectations, a mere psychological placebo-nocebo treatment was chosen that was new to all participants. They were instructed that visual black and white stripe patterns had been found to reliably alter the perception of pain. One group of participants received only the placebo-nocebo instruction (expectation), a second group experienced a placebo-nocebo treatment within a conditioning phase (experience) but no instruction, and a third group received the combination of both that is a placebo-nocebo instruction and a placebo-nocebo conditioning (experience + expectation). It was shown that only the experience + expectation group revealed significantly higher pain ratings and physiological responses during nocebo, compared to placebo trials of the succeeding test phase. These findings demonstrate that the induction of a mere psychological placebo-nocebo effect on pain is in principle possible. Most important, results indicate that such effects most likely rely on both, a positive treatment experience, due to the encounter of an effective intervention (placebo conditioning), and a positive expectation about the intervention (placebo instruction).Besides experience and expectation, the current mood state has been shown to modulate pain and to impact the induction of placebo and nocebo effects. In this vein it has been demonstrated that placebo effects come along with positive affect, while nocebo effects often occur together with elevated feelings of anxiety. To clarify the interaction of emotions and placebo-nocebo manipulations on pain perception, in Experiment 2 the paradigm of Experiment 1 was modified. Instead of black and white stripe patterns, positive and negative emotional pictures were presented, which either cued pain increase (nocebo) or pain decrease (placebo). Two experimental groups were compared, which differed with regard to the instructed contingency of positive pictures serving as placebo and negative pictures serving as nocebo cues or vice versa (congruent vs. incongruent). Results indicate that the differentiation of placebo and nocebo trials (behaviorally and physiologically) was more pronounced for the congruent compared to the incongruent group. However, in the incongruent group, affective pain ratings were also significantly higher for nocebo (positive pictures) than placebo (negative pictures) trials, similar to the congruent group. These findings demonstrate that a placebo-nocebo manipulation is capable to dampen and even reverse the originally pain augmenting effect of negative emotions. The results of Experiment 2 were further corroborated in Experiment 3, when the design was adapted to the fMRI scanner, and again a congruent and an incongruent experimental group were compared. Behavioral, physiological and neurophysiological markers of pain processing revealed a differentiation between nocebo and placebo conditions that was present irrespective of the experimental group. In addition, the fMRI analysis revealed an increased engagement of prefrontal areas for the incongruent group only, supposedly reflecting the reinterpretation or appraisal process when positive pictures were cueing negative outcomes. Taken together, the results of the present studies showed (a) that it is possible to induce a placebo-nocebo effect on pain solely by a psychological manipulation, (b) that both, prior experiences and positive expectation, are necessary preconditions for this placebo-nocebo effect, (c) that the impact of negative emotion on pain can be dampened and even reversed by placebo-nocebo manipulations, and (d) that most likely a cognitive top-down process is crucial for the induction of (psychological) placebo-nocebo effects. These results significantly enhance our understanding of psychological mechanisms involved in the induction of placebo-nocebo effects. Further, a fruitful foundation for future studies is provided, which will need to determine the contributions of primarily nocebo or placebo responses mediating the effects as demonstrated in the present studies. In a long-term perspective, the present findings may also help to exploit placebo effects and prevent from nocebo effect in clinical contexts by further elucidating crucial psychological factors that contribute to the placebo and nocebo response. N2 - Die Wahrnehmung von Schmerz kann durch eine Vielzahl von Faktoren beeinflusst werden, darunter biologische und pharmakologische Interventionen sowie potente kognitive und emotionale Manipulationen. Placebo- und Nocebo-effekte gehören mit zu den eindrucksvollsten Beispielen für die Wirksamkeit derartiger Manipulationen. Placebo- und Nocebo-Behandlungen können zu manifesten psychologischen und physiologischen Veränderungen führen, obwohl die verabreichten Substanzen frei von Wirkstoffen bzw. den angewandten Scheinbehandlungen keine Wirkung zugeschrieben wird. In der vorliegenden Dissertation wurden kognitive und emotionale Einflussfaktoren auf die Induktion von Placebo- und Nocebo-Effekten bei der Wahrnehmung von Schmerz untersucht. Darüber hinaus sollte die Möglichkeit zur Verwendung rein psychologischer Placebo-Nocebo Manipulationen für die Modulation von Schmerz getestet werden. Zwei zentrale Voraussetzungen für die Erzeugung von Placebo und Nocebo-Effekten sind vorherige Erfahrung (z.B. auf Grund früherer Erfahrungen mit einem Medikament) und Erwartung (z.B. eine positive oder negative persönliche Einstellung gegenüber einer Therapie). Bisher basierte die Forschung zu Placebo- und Nocebo-Effekten vornehmlich auf Ergebnissen von Untersuchungen die Schein-Behandlungen oder Leerpräparate einsetzten wie z.B. Tabletten, Cremes oder Injektionen, die herkömmlichen medizinischen Interventionen sehr ähnlich sind. Jedoch ergibt sich bei einem derartigen experimentellen Vorgehen stets das Problem einer Konfundierung der Ergebnisse durch den Einfluss früherer Erfahrungen oder der individuellen Erwartungshaltung an die Behandlung, die aus einer Vorgeschichte medizinischer Therapieerlebnissen herrührt. Daraus leitet sich die Notwendigkeit von anderweitigen, dem Probanden völlig unbekannten Placebo-Interventionen ab, um die jeweilige Beteiligung von Erwartungs- und Erfahrungsprozessen für die Induktion von Placebo- und Nocebo-Effekten bestimmen zu können. Zu diesem Zweck wurden in Experiment 1 Erwartung und Erfahrung in drei Experimentalgruppen stufenweise und unabhängig voneinander manipuliert. Um einer Ähnlichkeit zu früheren Behandlungs-Erfahrungen und dadurch abgeleiteten Erwartungen vorzubeugen, wurde ein rein psychologisches Placebo-Nocebo Verfahren herangezogen, das mit Sicherheit allen Teilnehmern unbekannt war. Sie wurden darüber informiert, dass die Betrachtung von schwarz-weißen Streifenmustern eine wissenschaftlich bestätigte Wirkung auf die Schmerzwahrnehmung hätte. Eine Gruppe der Teilnehmer erhielt lediglich eine Placebo-Nocebo Instruktion (Erwartung), eine zweite Gruppe erlebte tatsächlich die Kopplung von zwei verschiedenen Streifenmustern mit unterschiedlich starken Schmerzreizen während einer Konditionierungs-Phase (Erfahrung) bekam aber keine Instruktion und eine dritte Gruppe erhielt sowohl die Placebo-Nocebo Instruktion als auch die Placebo-Nocebo Konditionierung (Erfahrung + Erwartung). Es konnte gezeigt werden, dass während der anschließenden Testphase lediglich die kombinierte Erfahrung + Erwartung Gruppe signifikant unterschiedliche Schmerzratings und physiologische Reaktionen auf die Schmerzreize während der Placebo- im Vergleich zu den Nocebo-Durchgängen aufwies. Diese Ergebnisse belegen, dass die Induktion eines rein psychologischen Placebo-Nocebo Effektes auf die Schmerzwahrnehmung prinzipiell möglich ist. Besonders hervorzuheben ist dabei die Notwendigkeit beider Prozesse, nämlich einer tatsächlichen Erfahrung der Wirksamkeit der Therapie (Placebo-Nocebo Konditionierung) und einer positiven Erwartung hinsichtlich der Intervention (Placebo-Nocebo Instruktion). Neben Erfahrung und Erwartung, hat die momentane Stimmung entscheidenden Einfluss auf die die Induktion von Placebo- und Nocebo-Effekten einerseits, sowie generell auf die Wahrnehmung von Schmerz andererseits. In diesem Zusammenhang konnte gezeigt werden, dass Placebo-Effekte mit einer Verbesserung der Stimmung einhergehen, Nocebo-Effekte hingegen häufig von gesteigerter Angst begleitet sind. Um die Interaktion von Emotionen und Placebo-Nocebo Manipulationen zu eruieren, wurde das in Experiment 1 etablierte Paradigma angewendet und modifiziert. Anstelle von Streifenmustern, wurden positive und negative emotionale Bilder präsentiert, die entweder eine Schmerz-Verstärkung (Nocebo) oder eine Schmerz-Linderung (Placebo) anzeigten. Zwei Experimentalgruppen wurden miteinander verglichen, die sich hinsichtlich der Kontingenz von positiven Bildern als Placebo- und negativen Bildern als Nocebo-Indikator, bzw. umgekehrt, positiven Bildern als Nocebo- und negativen Bildern als Placebo-Indikator, unterschieden (kongruent vs. inkongruent). Es zeigte, dass die Unterscheidung (Schmerzratings und physiologische Reaktionen auf den Schmerzreiz) zwischen Placebo- und Nocebo-Durchgängen in der kongruenten Gruppe stärker ausgeprägt war als in der inkongruenten Gruppe. Allerdings waren die affektiven Schmerzratings der inkongruenten Gruppe ebenfalls in Nocebo-Durchgängen (positive Bilder) signifikant höher als in Placebo-Durchgängen (negative Bilder), ähnlich zur kongruenten Gruppe. Die Daten zeigen damit, dass eine Placebo-Nocebo Manipulation in der Lage ist, die genuin Schmerz verstärkende Wirkung negativer Emotionen abzuschwächen und sogar umzukehren. Die Befunde aus Experiment 2 konnten zusätzlich in Experiment 3 gestützt werden, welches das zuvor getestete Design ins fMRT überführte und gleichermaßen eine kongruente und eine inkongruente Experimentalgruppe miteinander verglich. Verhaltensmaße sowie physiologische und neurophysiologische Korrelate der Schmerzwahrnehmung ergaben eine eindeutige Differenzierung zwischen Placebo- und Nocebo-Durchgängen, unabhängig von der Experimentalgruppe. Darüber hinaus zeigte sich in der inkongruenten Bedingung eine verstärkte präfrontale Aktivierung für den Vergleich von Nocebo- und Placebo-Durchgängen, was potenziell auf einen zusätzlichen Re- Interpretations- oder Appraisal-Prozess zurückzuführen ist, der sich einstellt, wenn ein positives Bild eine negative Konsequenz vorhersagt. Zusammengefasst zeigen die vorliegenden Studien, dass es (a) möglich ist einen Placebo-Nocebo Effekt mit einer rein psychologischen Manipulation hervorzurufen, dass (b) im Fall rein psychologischer Placebo-Nocebo Manipulationen sowohl Erfahrung als auch positive Erwartung notwendig sind, dass (c) der Einfluss negativer Emotionen auf Schmerz mittels einer Placebo-Nocebo Manipulation reduziert und sogar umgekehrt werden kann und (d) höchstwahrscheinlich ein kognitiver (Neu-) Bewertungsprozess für die Induktion (psychologischer) Placebo-Nocebo Effekte essentiell ist. Die Ergebnisse tragen zum Verständnis der beteiligten psychologischen Prozesse bei der Induktion von Placebo-Nocebo Effekten erheblich bei. Darüber hinaus stellen die verwendeten Paradigmen eine vielseitige Ausgangsposition für zukünftige Studien dar, die klären müssen, ob für die gefunden Ergebnisse vornehmlich Placebo- oder Nocebo-Effekte verantwortlich sind. Perspektivisch könnten die vorliegenden Befunden helfen, die psychologischen Grundlagen der Placebo-Nocebo Antwort näher zu beleuchten und damit sogar im klinischen Kontext zum Ausschöpfen von Placebo- sowie zur Vorbeugung von Nocebo-Effekten beizutragen.

This can be accomplished by teaching important literary, scientific, and cultural knowledge; teaching strategies; motivating the acquisition and use of important conceptual knowledge and strategies; and encouraging the general tendencies supporting good information processing. Good information processing can be produced by years of appropriate educational input. Good information processors cannot be produced by short-term interventions.

The present study shows that the own name has the power to bias a person’s actions unconsciously even in conditions that render any other name ineffective. Participants judged whether a letter string on the screen was a name or a non-word while this target stimulus was preceded by a masked prime stimulus. Crucially, the participant’s own name was among these prime stimuli and facilitated reactions to following name targets whereas the name of another, yoked participant did not. Signal detection results confirmed that participants were not aware of any of the prime stimuli, including their own name. These results extend traditional findings on ‘‘breakthrough’’ phenomena of personally relevant stimuli to the domain of unconscious processing. Thus, the brain seems to possess adroit mechanisms to identify and process such stimuli even in the absence of conscious awareness.

The internet as the fastest source for celebrity gossip allows measuring the impact of such wardrobe malfunctions on the public in-terest in a celebrity. This measurement in turn allows conclusions about intention, motivation, and internet be-haviour of a wide variety of internet users. The present study exemplifies the use of an innovative non-reactive measure of active interest—the Search Volume Index—to assess the impact of a variety of internet-related phe-nomena, including wardrobe malfunctions. Results indicate that interest in a celebrity increases immediately af-ter such an event and stays at a high level for about three weeks (the wardrobe plateau).

In our psychophysiological model of panic attacks we postulate the following vicious circle: individuals with panic attacks perceive even quite small increases in heart rate and interpret these changes as being catastrophic. This elicits anxiety and a further increase in heart rate. To evaluate this model we conducted a field study of 28 subjects with panic attacks and 20 healthy controls. A 24 hr ambulatory ECG was recorded and the subjects were instructed to report any cardiac perceptions during this period and to rate the anxiety elicited by these perceptions. The incidence of cardiac perceptions was about the same in both groups, but only subjects with panic attacks reported anxiety associated with such perceptions. Analysis of the ECGs revealed that in both groups heart rate accelerations preceded cardiac perceptions. Following cardiac perceptions, the healthy controls showed a heart rate deceleration, whereas the subjects with panic attacks had a further acceleration. This heart rate increase after cardiac perceptions was positively related to the level of anxiety elicited by the perceptions. These results provide clear evidence in support of the vicious circle model of panic attacks.

A1 - Rickard, T. C. A1 - Yaroush, R. A. A1 - Bourne, L. E. J. T1 - Brain potentials during mental arithmetic: effects of extensive practice and problem difficulty N2 - Recent behavioral investigations indicate that the processes underlying mental arithmetic change systematically with practice from deliberate, conscious calculation to automatic, direct retrieval of answers from memory [Bourne, L.E.Jr. and Rickard, T.C., Mental calculation: The development of a cognitive skill, Paper presented at the Interamerican Congress of Psychology, San Jose, Costa Rica, 1991; Psychol. Rev., 95 (1988) 492-527]. Results reviewed by Moscovitch and Winocur [In: The handbook of aging and cognition, Erlbaum, Hillsdale, NJ, 1992, pp. 315-372] suggest that consciously controlled processes are more dependent on frontal lobe function than are automatic processes. It is appropriate, therefore to determine whether transitions in the locus of primary brain activity occur with practice on mental calculation. In this experiment, we examine the relationship between characteristics of event-related brain potentials (ERPs) and mental arithmetic. Single-digit mental multiplication problems varying in difficulty (problem size) were used, and subjects were trained on these problems for four sessions. Problem-size and practice effects were reliably found in behavioral measures (RT). The ERP was characterized by a pronounced late positivity after task presentation followed by a slow wave, and a negativity during response indication. These components responded differentially to the practice and problem-size manipulations. Practice mainly affected topography of the amplitude of positivity and offset latency of slow wave, and problem-size mainly offset latency of slow wave and pre-response negativity. Fronto-central positivity diminished from session to session, and the focus of positivity centered finally at centro-parietal regions. This finding suggests that frontal lobe processing is necessary as long as task performance is not automatized, while automatized arithmetic processing requires parietal brain activity only. The pre-response negativity observed in the first session and during more difficult tasks is assumed to reflect excitatory preparatory processes, which could be associated with activation of calculation strategies.

The current study investigated the accuracy and user-friendliness of P300-Brain Painting, a new BCI application developed to paint pictures using brain activity only. Two different versions of the P300-Brain Painting application were tested: A colored matrix tested by a group of ALS-patients (n = 3) and healthy participants (n = 10), and a black and white matrix tested by healthy participants (n = 10). The three ALS-patients achieved high accuracies; two of them reaching above 89% accuracy. In healthy subjects, a comparison between the P300-Brain Painting application (colored matrix) and the P300-Spelling application revealed significantly lower accuracy and P300 amplitudes for the P300-Brain Painting application. This drop in accuracy and P300 amplitudes was not found when comparing the P300-Spelling application to an adapted, black and white matrix of the P300-Brain Painting application. By employing a black and white matrix, the accuracy of the P300-Brain Painting application was significantly enhanced and reached the accuracy of the P300-Spelling application. ALS-patients greatly enjoyed P300-Brain Painting and were able to use the application with the same accuracy as healthy subjects. P300-Brain Painting enables paralyzed patients to express themselves creatively and to participate in the prolific society through exhibitions.

Such episodes where an agent acts, thereby causing changes in their environment constitute the sense of agency. In this thesis four series of experi-ments elucidate how the sense of agency is represented in complex action-event sequences, thereby bridging a gap between basic cognitive research and real-life practice. It builds upon extensive research on the sense of agency in unequivocal sequences consisting of single ac-tions and distinct, predominantly auditory, outcomes. Employing implicit as well as explicit measures, the scope is opened up to multi-step sequences. The experiments show that it is worthwhile devoting more research to complex action-event sequences. With a newly introduced auditory measure (Chapter II), common phenomena such as temporal binding and a decrease in agency ratings following distorted feedback were replicated in multi-step sequences. However, diverging results between traditional implicit and explicit measures call for further inspection. Multisensory integration appears to gain more weight when multiple actions have to be performed to attain a goal leading to more accurate representations of the own actions (Chapter III). Additionally, freedom of choice (Chapter III) as well as early spatial ambiguity altered the perceived timing of outcomes, while late spatial ambi-guity (Chapter IV) and the outcome’s self-relevance did not (Chapter V). The data suggests that the cognitive system is capable of representing multi-step action-event sequences implicitly and explicitly. Actions and sensory events show a temporal attraction stemming from a bias in the perception of outcomes. Explicit knowledge about causing an event-sequence facilitates neither feelings of control nor taking authorship. The results corroborate current theorizing on the un-derpinnings of temporal binding and the divergence between traditional implicit and explicit measures of the sense of agency. Promising avenues for further research include structured analyses of how much inferred causality contributes to implicit and explicit measures of agency as well as finding alternative measures to capture conceptual as well as non-conceptual facets of the agency experience with one method. N2 - Vom Läuten einer Klingel bis hin zum Kochen eines Fünf-Gänge Menüs – menschliches Handeln verändert die Umwelt. Situationen, in denen eine Person handelt und so Veränderungen in ihrer Umgebung bewirkt, konstituieren den Sense of Agency. Diese Arbeit präsentiert vier Experimentalreihen, die die Repräsentation des Sense of Agency in komplexen Handlungs-Ereignis-Sequenzen erforschen und so eine Brücke zwischen kognitiver Grundla-genforschung und Alltagspraxis schlagen. Aufbauend auf umfangreicher Forschung zum Sense of Agency in Sequenzen aus einzelnen Handlungen und eindeutigen, vorwiegend auditiven Handlungseffekten wird der Forschungsbereich durch Einsatz impliziter sowie expliziter Maße auf mehrschrittige Sequenzen erweitert. Mittels eines neuen auditiven Maßes (Kapitel II) wurden gängige Phänomene wie Temporal Binding und die Abnahme von Agency Ratings nach verfremdetem Feedback in mehrschrittigen Sequenzen repliziert. Müssen mehrere Handlungen ausgeführt werden, um ein Ziel zu erreichen, scheint multisensorische Integration stärker ins Gewicht zu fallen, was zu genaueren Repräsentationen der eigenen Handlungen führt (Kapitel III). Darüber hinaus veränderten Wahl-freiheit (Kapitel III) und frühe räumliche Ambiguität das wahrgenommene Timing von Hand-lungseffekten, späte räumliche Ambiguität (Kapitel IV) sowie Selbstrelevanz des Handlungsef-fekts taten dies nicht (Kapitel V). Die Daten deuten darauf hin, dass das kognitive System mehrschrittige Handlungs-Ereignis-Sequenzen sowohl implizit als auch explizit repräsentieren kann. Die zeitliche Kompression von Handlungs-Ereignis-Sequenzen ist auf eine Verzerrung der Wahrnehmung von Handlungseffekten zurückzuführen. Explizites Wissen über die Verursa-chung von Ereignis-Folgen fördert weder Kontrollerleben noch das Gefühl eigener Autoren-schaft. Die Ergebnisse bestätigen den derzeitigen Diskurs über die Grundlagen von Temporal Binding und die Divergenz zwischen den traditionellen impliziten und expliziten Maßen des Sense of Agency. Strukturierte Analysen zum Beitrag von Kausalität zu Sense of Agency sowie die Ent-wicklung alternativer Methoden zur Erfassung konzeptueller wie nicht-konzeptueller Facetten des Sense of Agency mit einem Maß würden zur Weiterentwicklung des Forschungsbereichs beitragen.

The social sciences have answered these concerns, providing many studies investigating different media types (e.g., social media, video games) and different related variables (e.g., psychological well-being, academic achievement). Within this big body of research, some research results have confirmed negative associations with frequent media use; other studies have found no or even positive relationships. With heterogeneous results, it is difficult to obtain a clear picture of the relationships and causalities of new media. The method of meta-analysis allows a synthesis of all existing data, providing an overall effect size as well as moderator and mediator analyses which might explain the heterogeneity. Three manuscripts present meta-analytic evidence related to a) the relationship between social media use and academic achievement, b) the relationship between video gaming and overweight, and c) the relationship between social media and psychological correlates. Manuscript #1 found small relationships which depend on the usage pattern of social media. The relationship is positive, as long as social media use is related to school. Manuscript #2 showed that children’s and adolescents’ video gaming is independent from their body mass, while adults who play more have a higher body mass. Manuscript #3 summarized existing meta-analytic evidence that links social media with psychological wellbeing, academic achievement, and narcissism with small to moderate effect sizes. All three manuscripts underscore the potential of meta-analyses to synthesize previous research and to identify moderators. Although meta-analyses are not necessarily superior to other approaches because of their limitations (e.g. limited information or quality of primary studies) they are very promising for media psychology. Meta-analyses can reduce complexity and might be helpful for the communication of research results to the general public. N2 - Die Entwicklung neuer Medien wurde von öffentlichen Debatten über mögliche negative Folgen begleitet. Wissenschaftler*innen reagierten auf diese Bedenken mit einer Vielzahl von Studien und untersuchten mögliche Effekte verschiedener Medientypen (z. B. soziale Medien, Videospiele) auf verschiedene Variablen (z. B. psychologisches Wohlbefinden, akademische Leistungen). Während manche Forschungsergebnisse die diskutierten negativen Zusammenhänge häufiger Mediennutzung bestätigten, fanden andere Studien jedoch keine oder sogar positive Zusammenhänge. Die Forschungslage zu medienpsychologischen Fragestellungen zeigt oft heterogene Ergebnisse, die keine abschließenden Aussagen erlauben. Eine Lösung für dieses Problem ist die Methode der Meta-Analyse. Hierbei werden alle vorhandenen Studien zusammengefasst und ein Gesamteffekt berechnet. Darüber hinaus können Moderator- und Mediatoranalysen durchgeführt werden, die die Heterogenität zwischen den Studien erklären könnten. In drei Manuskripten wurden a) die Beziehung zwischen Social Media-Nutzung und akademischen Leistungen, b) die Beziehung zwischen Videospielen und Übergewicht und c) die Beziehung zwischen sozialen Medien und psychologischen Korrelaten meta-analytisch untersucht. In Manuskript Nr. 1 zeigte sich, dass der Zusammenhang zwischen sozialen Medien und akademischer Leistung von der Art der Nutzung abhing. Der Zusammenhang war positiv, solange die Nutzung sozialer Medien akademischen Zwecken diente. Manuskript 2 zeigte, dass das Körpergewicht von Kindern und Jugendlichen nicht in Verbindung mit der Videospielenutzung stand, während Erwachsene, die mehr spielten, eine höhere Körpermasse hatten. Manuskript Nr. 3 fasste meta-analytische Studien mit gleichen Fragestellungen zu sozialen Medien und psychologischen Variablen (Wohlbefinden, akademische Leistung, Narzissmus) zusammen. Alle drei Manuskripte unterstreichen das Potenzial von Metaanalysen, den existierenden Forschungsstand zusammenzufassen und Moderatorvariablen zu identifizieren. Obwohl Meta-Analysen aufgrund ihrer Einschränkungen (z. B. die begrenzte Anzahl und Qualität von Primärstudien) anderen Methoden nicht unbedingt überlegen sind, sind sie dennoch für medienpsychologische Fragestellungen sehr vielversprechend. Metaanalysen sind in der Lage die Komplexität des Forschungsstands zu reduzieren und könnten für die Kommunikation von Forschungsergebnissen an die breite Öffentlichkeit hilfreich sein.

The current experiment is the first investigating the neuronal structures responsible for differences in the occurrence of such facial mimicry reactions by simultaneously measuring BOLD and facial EMG in an MRI scanner. Therefore, 20 female students viewed emotional facial expressions (happy, sad, and angry) of male and female avatar characters. During picture presentation, the BOLD signal as well as M. zygomaticus major and M. corrugator supercilii activity were recorded simultaneously. Results show prototypical patterns of facial mimicry after correction for MR-related artifacts: enhanced M. zygomaticus major activity in response to happy and enhanced M. corrugator supercilii activity in response to sad and angry expressions. Regression analyses show that these congruent facial reactions correlate significantly with activations in the IFG, SMA, and cerebellum. Stronger zygomaticus reactions to happy faces were further associated to increased activities in the caudate, MTG, and PCC. Corrugator reactions to angry expressions were further correlated with the hippocampus, insula, and STS. Results are discussed in relation to core and extended models of the mirror neuron system (MNS).

Kaum wahrgenommene Gerüche beeinflussen Ordentlichkeit (Holland, Hendriks, & Aarts, 2005). Kaubewegungen beeinflussen, als wie vertraut man vorher gesehene Namen bewertet (Topolinski, 2012). Die vorliegende Arbeit beschäftigt sich mit derartigen Auswirkungen von körperlichen Zuständen, Sinneswahrnehmungen und Handlun- gen auf psychische Zustände und Vorgänge, die als Embodiment bezeichnet werden. In der vorliegenden Arbeit wird zuerst Embodiment im Vergleich zur Computer- metapher des Informationsverarbeitungsansatzes definiert und Betrachtungen zu Metaphern für die menschliche Psyche im Allgemeinen aufgestellt. Danach werden verschiedene psychologische Mechanismen für Embodiment-Phänomene aufgezeigt. Kapitel 2 führt alle Embodiment-Phänomene auf drei verschiedene grundlegende psychische Mechanismen zurück, die alleine oder in Kombination alle Embodiment- Phänomene erklären können. Da die Untersuchung zugrundeliegender Mechanis- men bisher eher wenig verbreitet ist, werden außerdem empirische Testverfahren dargestellt, mit deren Hilfe zwischen verschiedenen Mechanismen für spezifische Phänomene unterschieden werden kann. Während die Inhalte dieser Arbeit also Embodiment-Phänomene sind, ist die Herangehensweise—die Untersuchung kog- nitiver Prozesse—in der Social Cognition Perspektive verwurzelt. Der empirische Teil der Arbeit untersucht einen spezifischen Embodiment-Effekt genauer, nämlich den Einfluss körperlicher Reinigung auf psychische Prozesse, die verkörperte Reinigung. In Kapitel 4 wird untersucht, inwiefern sich Hilfsbereitschaft nach eigenem moralischen oder unmoralischen Verhalten durch physikalische Reinigung ändert—inwiefern man sich also von einem moralisch positiven oder moralisch negativem Gefühl reinwaschen kann (zwei Experimente mit insgesamt 476 Teilnehmern). In Kapitel 5 wird untersucht, wie sich durch physikalische Reinigung die Änderungen in Optimismus und Selbstwert reduzieren, die durch Erfolg oder Misserfolg in einem vorangehenden Leistungstest hervorgerufen wor- den waren (drei Experimente mit insgesamt 372 Teilnehmern). Die Grundidee bei verkörperter Reinigung ist also, dass physikalische Reinigung nicht nur physis- che sondern auch psychische Rückstände entfernt. Das heißt, dass der Einfluss vorheriger Erfahrungen durch Händewaschen reduziert werden sollte. In dieser Arbeit sollen die psychologischen Prozesse untersucht werden, die den Einfluss von Reinigung auf die Psyche vermitteln könnten. Ausgehend von be- reits bekannten Auswirkungen körperlicher Reinigung auf verschiedene psychische Prozesse, werden zwei mögliche Erklärungen für das Phänomen der verkörperten Reinigung kontrastiert und über deren zugrundeliegende Prozesse spekuliert (Kapi- tel 3). Kapitel 4 vergleicht die Effekte verkörperter Reinigung, wenn die beiden Erklärungen konvergierende Vorhersagen machen (nach moralisch negativen Erin- nerungen) und wenn die beiden Erklärungen divergierende Vorhersagen machen (nach moralisch positiven Erinnerungen). Kapitel 5 untersucht dann eine der beiden Erklärungen genauer. Dafür werden verschiedene Aspekte der Reinigungshandlung variiert um die notwendigen und hinreichenden Kriterien für verkörperte Reinigung und damit auch die beteiligten psychischen Prozesse zu untersuchen. Die Ergebnisse des Einflusses verkörperter Reinigung in Kapitel 4 sind nicht interpretierbar, weil der vorausgesetzte Einfluss positiver und negativer moralischer Erinnerungen auf prosoziales Verhalten nicht nachweisbar war. Mit geändertem Grundparadigma ließ sich dann in Kapitel 5 ein stabiler Effekt verkörperter Reini- gung nachweisen. Eine Variation verschiedener Faktoren der Reinigung ergab, dass eine intentionale oder zumindest wissentliche Reinigung essentiell ist und dass sich diese Reinigung auf den eigenen Körper (und nicht auf einen Gegenstand) bezieht damit physische Reinigung zu psychischer Reinigung führt. Damit spielen sowohl inferentielle als auch automatisch Prozesse eine Rolle bei Effekten verkörperter Reinigung. Zum Abschluss der Arbeit werden die Erkenntnisse und Limitierungen der ak- tuellen Arbeit diskutiert und die beiden möglichen Reinigungserklärungen in einen anthropologischen Kontext gestellt. Anschließend wird der hier verfolgte Ansatz mit anderen Arten von Embodiment-Erklärungen verglichen. N2 - The present thesis examines embodiment—the body’s influence on psychological processes. Bodily states, perceptions, and actions influence cognitive processes; for example, a heavy backpack makes hills look steeper (Proffitt et al., 2003); and faint odors influence orderliness (Holland, Hendriks, & Aarts, 2005). In Chapter 2, embodiment phenomena are reviewed and classified according to three possible underlying mechanisms. Additionally, empirical tests for distinguishing between the workings of these mechanisms are discussed. The empirical part of the thesis examines one specific embodiment in more detail, namely embodied cleansing. The basic idea in embodied cleansing is that physical cleansing reduces not only physical but also psychological remnants of the past. For example, Chapter 4 examines whether prosocial behavior after one’s own moral or immoral behavior is changed by embodied cleansing; and Chapter 5 examines how changes in optimism and self-esteem as a result of previous success or failure in an achievement test are reduced by embodied cleansing. The present thesis examines psychological mechanisms that could explain embodied cleansing. For that, Chapter 3 derives and contrasts two possible explanations for embodied cleansing. Chapter 4 tests the effect of physical cleansing when both explanations make converging predictions (with morally negative memories) compared to when the two explanations make differing predictions (with morally positive memories). However, the results of embodied cleansing on prosocial behavior after (im)moral recall could not be examined as (im)moral recall, against expectations, did not influence prosocial behavior in the present paradigm. Chapter 5 more closely examines one of the two explanations. For that, different aspects of the act of cleaning one’s hands are varied to examine necessary and sufficient criteria for embodied cleansing. The results show that deliberate cleaning is essential for embodied cleansing; additionally the cleaning action has to refer to one’s own body (and not to an object). Thus, a combination of inferential and automatic processes seem to play a role in embodied cleansing. Finally the results are discussed in relation to other embodiment effects and explanations.

Following pretesting, 437 children were divided into training and control groups, with the former receiving training in clustering strategies. Trained children showed sizable strategy maintenance and transfer effects two weeks and six months later. Parents and teachers completed questionnaires about the teaching of strategies and their attributional beliefs about children's academic successes and failures. The differences in strategie behavior and attributions of German and American children were due, in part, to differences in strategy-enriched environments.
