Im Transtheoretischen Modell der Verhaltens{\"a}nderung (Prochaska \& DiClemente, 1983, 1992) werden f{\"u}nf Stufen postuliert. Ziel der vorliegenden Arbeit war es zu {\"u}berpr{\"u}fen, ob sich empirische Hinweise auf das Vorliegen von Stufen im Transtheoretischen Modell erbringen lassen. Dies wurde exemplarisch f{\"u}r den Verhaltensbereich der sportlichen Aktivit{\"a}t vorgenommen. Hierzu wurde {\"u}berpr{\"u}ft, ob den kognitiven Modellvariablen (Selbstwirksamkeitserwartung, wahrgenommene Vorteile, wahrgenommene Nachteile) auf den verschiedenen Stufen eine unterschiedliche Bedeutung f{\"u}r eine Verbesserung auf die n{\"a}chst h{\"o}here Stufe zukommt. Da die kausalen Zusammenh{\"a}nge innerhalb des Modells nicht gekl{\"a}rt sind, wurde zudem die Bedeutung des Sportverhaltens auf den Stufen untersucht. Zus{\"a}tzlich wurden explorativ Pr{\"a}diktoren der allgemeinen Stufenverbesserung, d.h. der Verbesserung um beliebig viele Stufen identifiziert sowie stufenspezifische Pr{\"a}diktoren der Stufenverschlechterung ermittelt. In die Sekund{\"a}ranalyse einer multizentrischen, kontrollierten Interventionsstudie gingen Daten von 610 Patienten ein, die eine medizinische Rehabilitation erhalten hatten. In die Auswertungen wurden Daten zu drei Messzeitpunkten einbezogen: Rehabilitationsbeginn, 3 Monate nach der Rehabilitation und 12 Monate nach der Rehabilitation. Zur Beantwortung der Fragestellungen wurden zwei der von Weinstein, Rothman und Sutton (1998) vorgeschlagenen Forschungsstrategien zum Nachweis von Stufen eingesetzt: Intraindividuelle Vorhersage der Stufenverbesserung zur Identifikation stufenspezifischer Pr{\"a}diktoren der Stufenverbesserung aufgrund l{\"a}ngsschnittlicher Daten sowie Untersuchung interindividueller Unterschiede zwischen benachbarten Stufen im Querschnitt zur {\"U}berpr{\"u}fung auf Diskontinuit{\"a}t. Die Ergebnisse der beiden Vorgehensweisen stimmen in weiten Teilen {\"u}berein. Insgesamt konnten in der vorliegenden Arbeit Hinweise darauf erzielt werden, dass sich der Prozess der Verhaltens{\"a}nderung in Stufen vollzieht, wobei die Daten lediglich eine Unterscheidung von drei Stufen rechtfertigen. Von den ber{\"u}cksichtigten Variablen scheint nur den wahrgenommenen Vorteilen und dem Verhalten stufenspezifisch eine unterschiedliche Bedeutung zuzukommen, wobei letzterem f{\"u}r die Differenzierung von Stufen eine geringere Bedeutung beigemessen wurde als den kognitiven Variablen. Die Ergebnisse zur Stufenverschlechterung weisen darauf hin, dass Faktoren, die f{\"u}r eine Verbesserung, und solche, die f{\"u}r eine Verschlechterung zwischen zwei Stufen relevant sind, nicht {\"u}berein stimmen. Aus den Ergebnissen werden Ansatzpunkte f{\"u}r die Gestaltung stufenspezifischer Interventionen abgeleitet.

Ein breites und nicht nachlassendes Interesse in Forschung und Praxis kommt insbesondere vorschulischen Trainingskonzepten zuteil, denen das Potenzial zugesprochen wird, sp{\"a}ter auftretenden Schwierigkeiten beim Erwerb der Schriftsprache wirksam vorzubeugen. Das W{\"u}rzburger Trainingsprogramm »H{\"o}ren, lauschen, lernen« stellt einen konzeptionell auf schriftspracherwerbstheoretischen Annahmen fundierten und mit mehreren evaluierenden Studien erprobten Trainingsansatz dar. Dieser bezweckt, Kindern den Erwerb des Lesens und Schreibens zu erleichtern. Dem Anspruch, sp{\"a}teren Lese-Rechtschreibschwierigkeiten effektiv vorzubeugen, unterliegt die vorschulische F{\"o}rderung bereichsspezifischer Kompetenzen des Schriftspracherwerbs, insbesondere der Kompetenz phonologische Bewusstheit. Die F{\"o}rderung wird optimal ausgesch{\"o}pft, sofern Empfehlungen einer qualitativen Implementierung umgesetzt werden, die als Manualtreue, Durchf{\"u}hrungsintensit{\"a}t, Programmdifferenzierung, Programmkomplexit{\"a}t, Implementierungsstrategien, Vermittlungsqualit{\"a}t und Teilnehmerreaktion spezifiziert sind. Zunehmend diskutiert sind in der Trainingsforschung, neben der theoretischen Fundierung und dem zu erbringenden Nachweis an empirischer Evidenz von Programmans{\"a}tzen, Kriterien der Praxistauglichkeit. Daher befasst sich die vorliegende Arbeit mit der Frage der Programmrobustheit gegen{\"u}ber Trainereffekten. Es nahmen 300 Kinder an dem W{\"u}rzburger Trainingsprogramm teil und wurden 64 Kindern gegen{\"u}bergestellt, die dem regul{\"a}ren Kindergartenprogramm folgten. Angeleitet durch das erzieherische Personal fand das 5-monatig andauernde Training innerhalb des Vorschuljahres statt. Die kindliche Entwicklung in den bereichsspezifischen Kompetenzen der phonologischen Bewusstheit und der Graphem-Phonem-Korrespondenz wurde vor und nach der Trainingsmaßnahme sowie zum Schul{\"u}bertritt und in den Kompetenzen des Rechtschreibens und Lesens zum Ende des ersten Schuljahres untersucht. Es ließen sich unmittelbar und langfristig Trainingseffekte des eingesetzten Programmes nachweisen; indessen blieb ein Transfererfolg aus. Der Exploration von Trainereffekten unterlag eine Eruierung der Praxistauglichkeit des Trainingsprogrammes anhand der erfolgten Implementierung durch das anleitende erzieherische Personal. Aus der urspr{\"u}nglich mit 300 Kindern aus 44 involvierten Kinderg{\"a}rten bestehenden Datenbasis wurden drei Subgruppen mit insgesamt 174 Kindern aus 17 Kinderg{\"a}rten identifiziert, bei denen deutliche Diskrepanzen zu unmittelbaren, langfristigen und transferierenden Effekten des Trainingsprogrammes auftraten. Exploriert wurden Unterschiede in der Durchf{\"u}hrung, um R{\"u}ckschl{\"u}sse auf qualitative Aspekte der Programmimplementierung zu ziehen. Die Befunde des Extremgruppenvergleichs deuteten an, dass weniger Aspekte der Manualtreue und Durchf{\"u}hrungsintensit{\"a}t ausschlaggebend f{\"u}r die Programmwirksamkeit waren; vielmehr schien f{\"u}r die Wirksamkeit des Trainingsprogrammes die Implementierung in der Art und Weise, wie die Trainingsinhalte den Kindern durch das erzieherische Personal vermittelt waren, entscheidend zu sein. Befunde zur eruierten Teilnehmerreaktion, die auf differenzielle F{\"o}rdereffekte verweisen, stellten die Trainingswirksamkeit insbesondere f{\"u}r Kinder heraus, bei denen prognostisch ein Risiko unterstellt war, sp{\"a}ter auftretende Schwierigkeiten mit der Schriftsprache zu entwickeln. Ferner zeichnete sich ab, dass neben der Qualit{\"a}t der Programmimplementierung scheinbar auch Unterschiede in der schulischen Instruktionsmethode des Lesens und Schreibens einen nivellierenden Einfluss auf den Transfererfolg des Programmes aus{\"u}bten.

Lebenslanges Lernen und damit eine kontinuierliche Weiterbildung der Mitarbeiter ist essentiell f{\"u}r Unternehmen, um auf dem schnelllebigen Arbeitsmarkt wettbewerbsf{\"a}hig zu sein. Die Bereitschaft und die Motivation von Menschen, dazuzulernen, ist jedoch sehr unterschiedlich. Eine m{\"o}gliche Erkl{\"a}rung daf{\"u}r liefert die dispositionelle Zielorientierung, welche der Achievement-Goal-Theorie entstammt. Das Konstrukt beschreibt, ob Menschen eine individuelle Pr{\"a}ferenz f{\"u}r Lernziele (z.B. Kompetenzzuwachs) oder Leistungsziele (z.B. gute Beurteilungen bekommen oder schlechte Beurteilungen vermeiden) haben. Neben den Pers{\"o}nlichkeitsaspekten konzentriert sich die Forschung im Rahmen der Achievement-Goal-Theorie auch auf den Einfluss der Umgebung auf Lern- und Leistungsprozesse. Die sogenannte arbeitsplatzbezogene Zielorientierung beschreibt die wahrgenommene Zielstruktur der Arbeitsumgebung und stellt das situationsbedingte Gegenst{\"u}ck der Dispositionen dar. Zahlreiche Befunde aus dem Bereich der p{\"a}dagogischen Psychologie zu Zielstrukturen der Umgebung zeigen einen Einfluss auf beispielsweise Lernerfolg, Motivation, Selbstregulationsprozesse oder Leistung. Zielstrukturen im Arbeitskontext stellen hingegen ein bisher wenig beachtetes Konstrukt dar. Ausgehend von den aktuellen Befunden zu Zielstrukturen, k{\"o}nnte die arbeitsplatzbezogene Zielorientierung jedoch einen wichtigen Beitrag leisten, wenn es um die Frage geht, wie Mitarbeiter unterst{\"u}tzt und zu Lernprozessen angeregt werden k{\"o}nnen. Die Identifizierung von lern- und leistungsf{\"o}rderlichen Zielstrukturen der Arbeitsumgebung w{\"u}rde wertvolle Ansatzpunkte f{\"u}r die Mitarbeiterentwicklung in der betrieblichen Praxis liefern. Im Rahmen von drei empirischen Studien wird der Relevanz der Zielorientierung im Arbeits-kontext nachgegangen. Neben der {\"U}berpr{\"u}fung eines ins Deutsche {\"u}bertragenen und angepassten Mess-instruments zur Erhebung der arbeitsplatzbezogenen Zielorientierung (Studie 1) steht vor allem die Untersuchung m{\"o}glicher Einfl{\"u}sse des Konstrukts auf arbeitsrelevante Variablen im Vordergrund, um f{\"o}rderliche Zielstrukturen zu identifizieren (Studie 1 \& 2). Dar{\"u}ber hinaus werden erstmalig m{\"o}gliche Person-Situation-Interaktionen in diesem Zusammenhang untersucht (Studie 2). Abschließend erfolgt eine Untersuchung m{\"o}glicher Antezedenten der arbeitsplatzbezogenen Zielorientierung, woraus sich erste wichtige Anhaltspunkte f{\"u}r Interventionsmaßnahmen am Arbeitsplatz ableiten lassen (Studie 3). Die Ergebnisse der Studien zeigen, dass insbesondere ein lernzielorientierter Arbeitsplatz f{\"o}rderlich f{\"u}r die untersuchten Variablen wie Lernerfolg, Leistung oder auch berufliche Selbstwirksamkeit ist. In Bezug auf die Interaktion von Person und Situation ergaben sich gemischte Befunde, die kein eindeutiges Interaktionsmuster aufweisen. Bei der Frage, wie ein lernzielorientierter Arbeitsplatz gef{\"o}rdert werden kann, erwies sich vor allem die Art und Weise, wie F{\"u}hrungskr{\"a}fte mit Fehlern umgehen, als relevant.

Zun{\"a}chst wird Zeitmanagement aus psychologischer Perspektive genauer betrachtet. W{\"a}hrend Zeitmanagement bislang, auch in der Forschung, vor allem vor dem Hintergrund popul{\"a}rer Ratgeberliteratur beschrieben wurde (z.B. Macan, Shahani, Dipboye \& Phillips, 1990, S. 761ff; Orpen, 1994, S. 394) ist es ein besonderes Anliegen im Rahmen dieser Arbeit gutes Zeitmanagement aus psychologischer Perspektive zu diskutieren: Was kann vor dem Hintergrund psychologischer Theorien und Forschungsbefunde unter gutem Zeitmanagement verstanden werden? Welche konkreten Verhaltensweisen zeichnen gutes Zeitmanagement aus? Verschiedene Zeitmanagementtechniken werden hierzu m{\"o}glichst verhaltensnah expliziert. Das so beschriebene Zeitmanagementverhalten diente als Grundlage f{\"u}r die korrelativen Studien sowie die Interventionsstudien zur Evaluation von Zeitmanagementtrainings. Koch und Kleinmann (2002, S. 212) verwiesen auf das Problem der unklaren theoretischen Fundierung von Zeitmanagementtrainings und sahen darin eine Ursache f{\"u}r die uneinheitliche Befundlage zur Wirksamkeit solcher Trainings. F{\"u}r den zweiten Teil der Arbeit wurde in drei korrelativen Studien untersucht, ob die Nutzung von Zeitmanagementtechniken mit Befinden und Leistung dergestalt assoziiert ist, dass sich Leistung und Befinden mit zunehmender Nutzungsh{\"a}ufigkeit von Zeitmanagementtechniken verbessern. Zu diesem Zweck wurden korrelative Studien mit Auszubildenden, Sachbearbeitern und F{\"u}hrungskr{\"a}ften durchgef{\"u}hrt. Ein besonderes Anliegen ist in diesem Kontext auch die Diskussion von gefundenen Unterschieden bez{\"u}glich der Zusammenh{\"a}nge zwischen Zeitmanagementverhalten, Leistung und Befinden zwischen den drei Zielgruppen.

Im Mittelpunkt steht dabei eine Interventionsstudie mit Sachbearbeitern (kaufm{\"a}nnischen Angestellten), die um zwei weitere Interventionsstudien mit Studierenden erg{\"a}nzt wurde. Als wichtige Ergebnisse der Studien k{\"o}nnen festgehalten werden, dass (a) gutes Zeitmanagementverhalten insbesondere bei F{\"u}hrungskr{\"a}ften und Sachbearbeitern in Zusammenhang mit Befinden, weniger mit Leistung, steht, (b) Zeitmanagementtrainings geeignet sind, die erlebte Zeitkontrolle zu steigern und das Stresserleben zu reduzieren, (c), Zeitmanagementtrainings auch eine pr{\"a}ventive Wirkung in Bezug auf das Stresserleben bei steigenden Anforderungen haben k{\"o}nnen, (d) einem wesentlichen Zeitmanagementproblem, dem Aufschieben der Bearbeitung von Aufgaben bis kurz vor eine deadline, durch ein Zeitmanagementtraining erfolgreich begegnet und (e) lediglich eine tendenzielle Wirkung eines Zeitmanagementtrainings auf Leistungsvariablen nachgewiesen werden konnte.}, subject = {Terminplanung}, language = {de} } @article{HerbertSfaerleaBlumenthal2013, author = {Herbert, Cornelia and Sf{\"a}rlea, Anca and Blumenthal, Terry}, title = {Your emotion or mine: labeling feelings alters emotional face perception—an ERP study on automatic and intentional affect labeling}, series = {Frontiers in Human Neuroscience}, journal = {Frontiers in Human Neuroscience}, doi = {10.3389/fnhum.2013.00378}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-97065}, year = {2013}, abstract = {Empirical evidence suggests that words are powerful regulators of emotion processing. Although a number of studies have used words as contextual cues for emotion processing, the role of what is being labeled by the words (i.e., one's own emotion as compared to the emotion expressed by the sender) is poorly understood. The present study reports results from two experiments which used ERP methodology to evaluate the impact of emotional faces and self- vs. sender-related emotional pronoun-noun pairs (e.g., my fear vs. his fear) as cues for emotional face processing. The influence of self- and sender-related cues on the processing of fearful, angry and happy faces was investigated in two contexts: an automatic (experiment 1) and intentional affect labeling task (experiment 2), along with control conditions of passive face processing. ERP patterns varied as a function of the label's reference (self vs. sender) and the intentionality of the labeling task (experiment 1 vs. experiment 2). In experiment 1, self-related labels increased the motivational relevance of the emotional faces in the time-window of the EPN component. Processing of sender-related labels improved emotion recognition specifically for fearful faces in the N170 time-window. Spontaneous processing of affective labels modulated later stages of face processing as well. Amplitudes of the late positive potential (LPP) were reduced for fearful, happy, and angry faces relative to the control condition of passive viewing. During intentional regulation (experiment 2) amplitudes of the LPP were enhanced for emotional faces when subjects used the self-related emotion labels to label their own emotion during face processing, and they rated the faces as higher in arousal than the emotional faces that had been presented in the "label sender's emotion" condition or the passive viewing condition.

Result A significantly stronger reduction of general (p = 0.038, d = 0.42) and emotional fatigue (p = 0.004, d = 0.59) and a higher increase of practice frequency (p = 0.015, d = 0.52) between T1 and T2 were found for the reminder group compared to the no-reminder group. In the mediation model, practice frequency as a mediator partially explained the changes in emotional fatigue (indirect effect B =  - 0.10). Long-term effects of yoga therapy regarding fatigue, depression, and quality of life were found (F > 7.46, p < 0.001, d > 0.54). Conclusion Weekly reminder e-mails after yoga therapy can positively affect general and emotional fatigue and help cancer patients with fatigue establish a regular yoga practice at home. However, higher practice frequency did not lead to higher physical or cognitive fatigue improvement, suggesting other factors that mediate efficacy on physical or cognitive fatigue, such as mindfulness or side effects of therapy.}, language = {en} } @article{ZetzlRennerPittigetal.2021, author = {Zetzl, Teresa and Renner, Agnes and Pittig, Andre and Jentschke, Elisabeth and Roch, Carmen and van Oorschot, Birgitt}, title = {Yoga effectively reduces fatigue and symptoms of depression in patients with different types of cancer}, series = {Supportive Care in Cancer}, volume = {29}, journal = {Supportive Care in Cancer}, issn = {0941-4355}, doi = {10.1007/s00520-020-05794-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235415}, pages = {2973-2982}, year = {2021}, abstract = {Purpose Examine the effects of an 8-week yoga therapy on fatigue in patients with different types of cancer. Methods A total of 173 cancer patients suffering from mild to severe fatigue were randomly allocated to yoga intervention (n = 84) (IG) versus waitlist control group (CG) (n = 88). Yoga therapy consisted of eight weekly sessions with 60 min each. The primary outcome was self-reported fatigue symptoms. Secondary outcomes were symptoms of depression and quality of life (QoL). Data were assessed using questionnaires before (T0) and after yoga therapy for IG versus waiting period for CG (T1). Results A stronger reduction of general fatigue (P = .033), physical fatigue (P = .048), and depression (P < .001) as well as a stronger increase in QoL (P = .002) was found for patients who attended 7 or 8 sessions compared with controls. Within the yoga group, both higher attendance rate and lower T0-fatigue were significant predictors of lower T1-fatigue (P ≤ .001). Exploratory results revealed that women with breast cancer report a higher reduction of fatigue than women with other types of cancer (P = .016) after yoga therapy. Conclusion The findings support the assumption that yoga therapy is useful to reduce cancer-related fatigue, especially for the physical aspects of fatigue. Women with breast cancer seem to benefit most, and higher attendance rate results in greater reduction of fatigue.

Es wird angenommen, dass f{\"u}r die visuelle Wahrnehmung beim Fahren drei Prozesse zur Steuerung der Aufmerksamkeit beitragen. (1) {\"U}ber top-down Prozesse wird die Aufmerksamkeit auf f{\"u}r die aktuelle Handlung besonders relevante Situationsbestandteile gelenkt. (2) Explorative Wahrnehmung dient dazu, ein umfassenderes Situationsmodell zu entwickeln, das neben aktuell handlungssteuernden Situationsbestandteilen auch andere, potentiell aufgabenrelevante Ob¬jekte zu einem umfassenderen Abbild der Situation integriert. (3) Saliente Reize k{\"o}nnen {\"u}ber bottom-up Aktivierung die Aufmerksamkeit auf sich ziehen. Es ist bekannt, dass Fahrer w{\"a}hrend der Bearbeitung visueller Zweitaufgaben mit ihrem Blick und damit mit ihrer Aufmerksamkeit wiederholt zwischen Fahr- und Nebenaufgabe wechseln. Grundlage der experimentellen Arbeiten ist die Idee, dass hierbei die Ausrichtung der Aufmerksamkeit in der Fahraufgabe {\"u}ber top-down Prozesse gesteuert wird und auf einem mentalen Abbild der Situation basiert. Vor dem Beginn der Nebenaufgabe fokussiert der Fahrer auf die Fahrsituation, bewertet sie und entwickelt eine Antizipation der zuk{\"u}nftigen Situationsentwicklung. Das entstehende Situationsmodell entscheidet dar{\"u}ber, wie viel Aufmerksamkeit w{\"a}hrend der Nebenaufgabe auf die Fahraufgabe verwendet wird, und welche Situationsbestandteile durch die Blicke zur Straße kontrolliert werden. Der Fahrer lenkt {\"u}ber top-down Prozesse seine Aufmerksamkeit auf als relevant f{\"u}r die Situationsentwicklung bewertete Objekte. Andere Objekte, sowie eine von der aktuellen Fahraufgabe unabh{\"a}ngige, explorative Wahrnehmung der Fahrsituation werden w{\"a}hrend der Nebenaufgabe vernachl{\"a}ssigt. Aus der Literatur ergeben sich außerdem Hinweise darauf, dass eine reizbasierte bottom-up Ausrichtung der Aufmerksamkeit w{\"a}hrend visueller Ablenkung zumindest eingeschr{\"a}nkt, wenn nicht sogar zeitweise vollst{\"a}ndig unterdr{\"u}ckt ist. Die durchgef{\"u}hrten experimentellen Arbeiten finden in der Fahrsimulation Belege f{\"u}r die angenommen top-down Steuerung der Aufmerksamkeit w{\"a}hrend visueller Nebenaufgaben beim Fahren. Es werden zwei unterschiedliche Messans{\"a}tze verwendet. Studie 1 und 2 greifen auf die Analyse des Blickverhaltens zur{\"u}ck. In diesen beiden Studien absolvieren die Testfahrer l{\"a}ngere, anspruchsvolle Fahrten, w{\"a}hrend denen visuelle Nebenaufgaben bearbeitet werden. Es ergeben sich Hinweise auf eine tiefere visuelle Verarbeitung der Fahrszene direkt vor dem Beginn der Nebenaufgabe. W{\"a}hrend der Bearbeitung der visuellen Nebenaufgaben passen die Fahrer ihre Aufmerksamkeitsverteilung an die Erfordernisse der Fahrsituation an: In anspruchsvollen Fahrsituationen wird h{\"a}ufiger und l{\"a}nger auf die Straße geblickt als in weniger beanspruchenden Situationen. Es finden sich außerdem Hinweise daf{\"u}r, dass spezifische Fahrfehler mit einer fehlerhaften Ausrichtung der Aufmerksamkeit in der Fahrsituation in Zusammenhang stehen. Studie 3 und 4 verwenden das Ph{\"a}nomen der Change Blindness als Indikator f{\"u}r die Ausrichtung der Aufmerksamkeit. Im Rahmen von Fahrten mit kontrollierten Situationsbedingungen wird die Hypothese untersucht, dass w{\"a}hrend der Bearbeitung visueller Nebenaufgabe die fahrbezogene Aufmerksamkeit auf fahrrelevante Situationsbestandteile gelenkt wird. Die Testfahrer n{\"a}hern sich wiederholt Kreuzungen an. W{\"a}hrend der Anfahrten wird {\"u}ber Okklusion ein Blickverhalten vorgegeben, das dem bei der Bearbeitung visueller Nebenaufgaben {\"a}hnelt. Die Fahrer sollen mit Tastendruck reagieren, wenn sie pl{\"o}tzliche {\"A}nderungen bemerken. Die {\"A}nderungen k{\"o}nnen sowohl relevante als auch irrelevante Fahrzeuge betreffen. Die Ergebnisse zeigen eine schlechte Entdeckungsleistung f{\"u}r {\"A}nderungen an irrelevanten Fahrzeugen. {\"A}nderungen an relevanten Objekten werden dagegen so gut wie immer bemerkt. Ob die {\"A}nderung durch Okklusion maskiert wird oder ob sie stattfindet, w{\"a}hrend die Fahrer die Straße sehen, hat keinen eindeutigen Ein¬fluss auf die Entdeckungsleistung. Dies kann ein Hinweis darauf sein, dass in der untersuchten Doppelaufgabensituation keine bottom-up Ausrichtung der Aufmerksamkeit erfolgt. Die angenommene top-down gesteuerte Beschr{\"a}nkung der Aufmerksamkeit auf als relevant bewertete Bestandteile der Fahrsituation hat Konsequenzen f{\"u}r die Analyse von Verkehrsunf{\"a}llen. Unf{\"a}lle infolge von visueller Ablenkung durch selbst initiierte Zweitaufgaben sind dann besonders wahrscheinlich, wenn das Situationsmodell des Fahrers falsch oder ungenau ist. Dies kann beispielsweise geschehen, wenn ein peripheres, nicht beachtetes Objekt pl{\"o}tzlich relevant wird und eine Reaktion des Fahrers erforderlich macht.

The aim of this study was to investigate (i) how common HAD in German desk-based workers are, and how frequently HADs are used, (ii) to identify sociodemographic, health-related, and psycho-social variables of workday sitting including having a HAD, and (iii) to analyse sociodemographic, health-related, and psycho-social variables of users and non-users of HADs. Methods: A cross-sectional sample of 680 participants (51.9\% men; 41.0 ± 13.1 years) in a desk-based occupation was interviewed by telephone about their occupational sitting and standing proportions, having and usage of a HAD, and answered questions concerning psycho-social variables of occupational sitting. The proportion of workday sitting was calculated for participants having an HAD (n = 108) and not-having an HAD (n = 573), as well as for regular users of HAD (n = 54), and irregular/non-users of HAD (n = 54). Linear regressions were conducted to calculate associations between socio-demographic, health-related, psychosocial variables and having/not having an HAD, and the proportion of workday sitting. Logistic regressions were executed to examine the association of mentioned variables and participants' usage of HADs. Results: Sixteen percent report that they have an HAD, and 50\% of these report regular use of HAD. Having an HAD is not a correlate of the proportion of workday sitting. Further analysis restricted to participants having available a HAD highlights that only the 'perceived advantages of sitting less' was significantly associated with HAD use in the fully adjusted model (OR 1.75 [1.09; 2.81], p < 0.05). Conclusions: The present findings indicate that accompanying behavioral action while providing an HAD is promising to increase the regular usage of HAD.

For example, traditional theories cannot account for refusals to cooperate if cooperation would result in higher payoffs. A prominent illustration are responders' rejections of positive but unequal payoffs in the Ultimatum Game. To accommodate this anomaly in a rational framework one needs to assume both a preference for higher payoffs and a preference for equal payoffs. The current set of studies shows that the relative weight of these preference components depends on external conditions and that consumption priming may decrease responders' rejections of unequal payoffs. Specifically, we demonstrate that increasing the accessibility of consumption-related information accentuates the preference for higher payoffs. Furthermore, consumption priming increased responders' reaction times for unequal payoffs which suggests an increased conflict between both preference components. While these results may also be integrated into existing social preference models, we try to identify some basic psychological processes underlying economic decision making. Going beyond the Ultimatum Game, we propose that a distinction between comparative and deductive evaluations may provide a more general framework to account for various anomalies in behavioral economics.}, language = {en} } @article{LenhardMintenLenhard2023, author = {Lenhard, Alexandra and Minten, Marie-Pierre and Lenhard, Wolfgang}, title = {When biology takes over: TV formats like The Bachelor and The Bachelorette confirm evolutionary theories of partner selection}, series = {Frontiers in Psychology}, volume = {14}, journal = {Frontiers in Psychology}, issn = {1664-1078}, doi = {10.3389/fpsyg.2023.1219915}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-325717}, year = {2023}, abstract = {Introduction: In this study, we investigated the impact of age on mate selection preferences in males and females, and explored how the formation and duration of committed relationships depend on the sex of the person making the selection.

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.

The present research examined whether a priming influence is diminished by task procedures that encourage accurate judgments of the targets. Participants were motivated to categorize the affective meaning of nonsense targets accurately by being made to believe that a true word was presented in each trial and by providing feedback on (allegedly) incorrect responses. This condition produced robust priming effects. Priming was however reduced and less reliable relative to more typical AMP conditions in which participants guessed the meaning of openly presented nonsense targets. Affective judgments of nonsense targets were not affected by advance knowledge of the response mapping during the priming phase, which argues against a response-priming explanation of AMP effects. These findings show that affective primes influence evaluative judgments even in conditions in which the motivation to provide accurate responses is high and a priming of motor responses is not possible. Priming effects were however weaker with high accuracy motivation, suggesting that a focus on accurate judgments is an effective strategy to control for an unwanted priming influence in the AMP.}, language = {en} } @article{Pfister2011, author = {Pfister, Roland}, title = {Wardrobe Malfunctions and the Measurement of Internet Behaviour}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-69067}, year = {2011}, abstract = {The wardrobe malfunction—an unanticipated exposure of bodily parts in the public—has become a prevailing issue in concerts, shows and other celebrity events that is reliably reported by the media.

Specifically, participants who took ownership over a more corpulent virtual body with intact visuo-tactile congruency increased safety distances towards the laboratory's walls compared to participants who experienced the same illusion with deteriorated visuo-tactile congruency. This effect is in line with the body schema more readily adapting to a more corpulent body after receiving congruent tactile information.

Yet, there is a population of users estimated between 10 to 50\% not able to achieve reliable control and only about 20\% of users achieve high (80-100\%) performance. Predicting performance prior to BCI use would facilitate selection of the most feasible system for an individual, thus constitute a practical benefit for the user, and increase our knowledge about the correlates of BCI control. In a recent study, we predicted SMR-BCI performance from psychological variables that were assessed prior to the BCI sessions and BCI control was supported with machine-learning techniques. We described two significant psychological predictors, namely the visuo-motor coordination ability and the ability to concentrate on the task. The purpose of the current study was to replicate these results thereby validating these predictors within a neurofeedback based SMR-BCI that involved no machine learning.Thirty-three healthy BCI novices participated in a calibration session and three further neurofeedback training sessions. Two variables were related with mean SMR-BCI performance: (1) a measure for the accuracy of fine motor skills, i.e., a trade for a person's visuo-motor control ability; and (2) subject's "attentional impulsivity". In a linear regression they accounted for almost 20\% in variance of SMR-BCI performance, but predictor (1) failed significance. Nevertheless, on the basis of our prior regression model for sensorimotor control ability we could predict current SMR-BCI performance with an average prediction error of M = 12.07\%. In more than 50\% of the participants, the prediction error was smaller than 10\%. Hence, psychological variables played a moderate role in predicting SMR-BCI performance in a neurofeedback approach that involved no machine learning.

Visual complexity can be described as, "a picture of a few objects, colors, or structures would be less complex than a very colorful picture of many objects that is composed of several components." Prior studies have reported a relationship between affect and visual complexity, where complex pictures are rated as more pleasant and arousing. However, a relationship in the opposite direction, an effect of affect on visual complexity, is also possible; emotional arousal and valence are known to influence selective attention and visual processing. In a series of experiments, we found that ratings of visual complexity correlated with affective ratings, and independently also with computational measures of visual complexity. These computational measures did not correlate with affect, suggesting that complexity ratings are separately related to distinct factors. We investigated the relationship between affect and ratings of visual complexity, finding an 'arousal-complexity bias' to be a robust phenomenon. Moreover, we found this bias could be attenuated when explicitly indicated but did not correlate with inter-individual difference measures of affective processing, and was largely unrelated to cognitive and eyetracking measures. Taken together, the arousal-complexity bias seems to be caused by a relationship between arousal and visual processing as it has been described for the greater vividness of arousing pictures. The described arousal-complexity bias is also of relevance from an experimental perspective because visual complexity is often considered a variable to control for when using pictorial stimuli.}, language = {en} } @phdthesis{Grossekathoefer2022, author = {Großekath{\"o}fer, Jonas David}, title = {Virtually Valid?

They are crucial for navigating the world and communicating with others. Nevertheless, research in recent years shows that many findings from experimental research on gaze behavior cannot be transferred from the laboratory to everyday behavior. For example, the frequency with which conspecifics are looked at is considerably higher in experimental contexts than what can be observed in daily behavior. In short: findings from laboratories cannot be generalized into general statements. This thesis is dedicated to this matter. The dissertation describes and documents the current state of research on social attention through a literature review, including a meta-analysis on the /gaze cueing/ paradigm and an empirical study on the robustness of gaze following behavior. In addition, virtual reality was used in one of the first studies in this research field. Virtual reality has the potential to significantly improve the transferability of experimental laboratory studies to everyday behavior. This is because the technology enables a high degree of experimental control in naturalistic research designs. As such, it has the potential to transform empirical research in the same way that the introduction of computers to psychological research did some 50 years ago. The general literature review on social attention is extended to the classic /gaze cueing/ paradigm through a systematic review of publications and a meta-analytic evaluation (Study 1). The cumulative evidence supported the findings of primary studies: Covert spatial attention is directed by faces. However, the experimental factors included do not explain the surprisingly large variance in the published results. Thus, there seem to be further, not well-understood variables influencing these social processes. Moreover, classic /gaze cueing/ studies have limited ecological validity. This is discussed as a central reason for the lack of generalisability. Ecological validity describes the correspondence between experimental factors and realistic situations. A stimulus or an experimental design can have high and low ecological validity on different dimensions and have different influences on behavior. Empirical research on gaze following behavior showed that the /gaze cueing/ effect also occurs with contextually embedded stimuli (Study 2). The contextual integration of the directional cue contrasted classical /gaze cueing/ studies, which usually show heads in isolation. The research results can thus be transferred /within/ laboratory studies to higher ecologically valid research paradigms. However, research shows that the lack of ecological validity in experimental designs significantly limits the transferability of experimental findings to complex situations /outside/ the laboratory. This seems to be particularly the case when social interactions and norms are investigated. However, ecological validity is also often limited in these studies for other factors, such as contextual embedding /of participants/, free exploration behavior (and, thus, attentional control), or multimodality. In a first study, such high ecological validity was achieved for these factors with virtual reality, which could not be achieved in the laboratory so far (Study 3). Notably, the observed fixation patterns showed differences even under /most similar/ conditions in the laboratory and natural environments. Interestingly, these were similar to findings also derived from comparisons of eye movement in the laboratory and field investigations. These findings, which previously came from hardly comparable groups, were thus confirmed by the present Study 3 (which did not have this limitation). Overall, /virtual reality/ is a new technical approach to contemporary social attention research that pushes the boundaries of previous experimental research. The traditional trade-off between ecological validity and experimental control thus becomes obsolete, and laboratory studies can closely inherit an excellent approximation of reality. Finally, the present work describes and discusses the possibilities of this technology and its practical implementation. Within this context, the extent to which this development can still guarantee a constructive classification of different laboratory tests in the future is examined.}, subject = {Aufmerksamkeit}, language = {en} } @article{HilgerHaegeZedleretal.2023, author = {Hilger, Kirsten and H{\"a}ge, Anne-Sophie and Zedler, Christina and Jost, Michael and Pauli, Paul}, title = {Virtual reality to understand pain-associated approach behaviour: a proof-of-concept study}, series = {Scientific Reports}, volume = {13}, journal = {Scientific Reports}, doi = {10.1038/s41598-023-40789-z}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-357817}, year = {2023}, abstract = {Pain-associated approach and avoidance behaviours are critically involved in the development and maintenance of chronic pain. Empirical research suggests a key role of operant learning mechanisms, and first experimental paradigms were developed for their investigation within a controlled laboratory setting. We introduce a new Virtual Reality paradigm to the study of pain-related behaviour and investigate pain experiences on multiple dimensions. The paradigm evaluates the effects of three-tiered heat-pain stimuli applied contingent versus non-contingent with three types of arm movements in naturalistic virtual sceneries. Behaviour, self-reported pain-related fear, pain expectancy and electrodermal activity were assessed in 42 healthy participants during an acquisition phase (contingent movement-pain association) and a modification phase (no contingent movement-pain association). Pain-associated approach behaviour, as measured by arm movements followed by a severe heat stimulus, quickly decreased in-line with the arm movement-pain contingency. Slower effects were observed in fear of movement-related pain and pain expectancy ratings. During the subsequent modification phase, the removal of the pain contingencies modified all three indices. In both phases, skin conductance responses resemble the pattern observed for approach behaviour, while skin conductance levels equal the pattern observed for the self-ratings. Our findings highlight a fast reduction in approach behaviour in the face of acute pain and inform about accompanying psychological and physiological processes. We discuss strength and limitations of our paradigm for future investigations with the ultimate goal of gaining a comprehensive understanding of the mechanisms involved in chronic pain development, maintenance, and its therapy.}, language = {en} } @phdthesis{Braun2013, author = {Braun, Barbara}, title = {Versorgung pathologischer Gl{\"u}cksspieler: Differentielle Aspekte der Inanspruchnahme von Hilfsangeboten}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-95703}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2013}, abstract = {Ziele.

Methodik. Die Arbeit basiert auf drei Studien: einer Onlinestudie (OS), einer Versorgungsstudie (VS) und einer Bev{\"o}lkerungsstudie (BS). In der OS wurde eine Gelegenheitsstichprobe von Personen, die einen im Internet bereitgestellten Selbsttest zu pathologischem Gl{\"u}cksspielen (PG) vollst{\"a}ndig ausf{\"u}llten (n=277) und bei Erf{\"u}llen der Einschlusskriterien anschließend an einer vertiefenden Studie teilnahmen (n=52), hinsichtlich soziodemographischer Charakteristika, Spielverhalten und spielbezogener Motive, PG inklusive Folgen, Beratungserfahrungen sowie psychopathologischen Variablen untersucht. In den anderen Studien wurden weitestgehend dieselben Instrumente verwendet. Die VS war eine Verlaufsstudie (Messzeitpunkte: Behandlungsbeginn und -ende), bei der konsekutiv Klienten aus n=36 ambulanten Suchthilfeeinrichtungen in Bayern aufgenommen wurden, die sich zwischen April 2009 und August 2010 vorstellten (n=461).

Zum Zugang zur Versorgung sind 1.1) {\"u}ber das Internet erreichbare Gl{\"u}cksspieler haupts{\"a}chlich junge, ledige M{\"a}nner, von denen ungef{\"a}hr die H{\"a}lfte die Diagnose PG erf{\"u}llen. Anhand der Spielmotive lassen sich drei Spielerklassen abbilden, die sich hinsichtlich ihres Schweregrads von PG unterschieden. Die Bereitschaft zur Teilnahme an einem Online-Pr{\"a}ventionsprogramm h{\"a}ngt haupts{\"a}chlich mit der Anzahl erf{\"u}llter DSM-IV-Kriterien f{\"u}r PG zusammen. Im Gegensatz zur VS sind die online erreichten Gl{\"u}cksspieler j{\"u}nger und zu einem h{\"o}heren Anteil subklinisch pathologische Gl{\"u}cksspieler (SPG, ein bis vier erf{\"u}llte DSM-IV-Kriterien f{\"u}r PG). 1.2) Hinsichtlich der Faktoren der Inanspruchnahme best{\"a}tigen sich systematische Unterschiede zwischen Gl{\"u}cksspielern in Behandlung und nicht in Behandlung. Ebenso zeigen sich Unterschiede zwischen SPGr und pathologischen Gl{\"u}cksspielern (PGr). Dabei ist die Anzahl erf{\"u}llter DSM-IV-Kriterien f{\"u}r PG der wichtigste Pr{\"a}diktor f{\"u}r einen positiven Behandlungsstatus. Auch soziodemographische Merkmale, insbesondere Alter und Staatsangeh{\"o}rigkeit, spielen eine Rolle. 1.3) Die Mehrheit der Klienten in ambulanten Suchthilfeeinrichtungen ist m{\"a}nnlich, durchschnittlich 37 Jahre alt, ledig und kinderlos und hat h{\"a}ufig eine ausl{\"a}ndische Staatsb{\"u}rgerschaft. Die am h{\"a}ufigsten gespielte und bevorzugte Spielform ist das Spielen an Geldspielautomaten. Viele der Klienten haben bereits im Vorfeld Hilfe in Anspruch genommen und Gr{\"u}nde f{\"u}r die Vorstellung in der Beratungsstelle waren in ungef{\"a}hr drei Viertel der F{\"a}llen finanzielle Probleme und bei ungef{\"a}hr der H{\"a}lfte Probleme in der Partnerschaft.

This applies even more to the reaction time-based CIT (RT-CIT), where no such research is available so far. The current study tested the application of the RT-CIT for an imaginary mock crime scenario both in a sample of prisoners (n = 27) and a matched control group (n = 25). Results revealed a high validity of the RT-CIT for discriminating between crime-related and crime-unrelated information, visible in medium to very high effect sizes for error rates and reaction times. Interestingly, in accordance with theories that criminal offenders may have worse response inhibition capacities and that response inhibition plays a crucial role in the RT-CIT, CIT-effects in the error rates were even elevated in the prisoners compared to the control group. No support for this hypothesis could, however, be found in reaction time CIT-effects. Also, performance in a standard Stroop task, that was conducted to measure executive functioning, did not differ between both groups and no correlation was found between Stroop task performance and performance in the RT-CIT. Despite frequently raised concerns that the RT-CIT may not be applicable in non-student and forensic populations, our results thereby do suggest that such a use may be possible and that effects seem to be quite large.

However, data of naturalistic driving studies revealed that approximately the half of all alarms activated by conventional FCA systems represented unnecessary alarms. In these situations, the alarm activation was correct according to the implemented algorithm, whereas the alarms led to no or only minimal driver responses. Psychological research can make an important contribution to understand drivers' needs when interacting with driver assistance systems. The overarching objective of this thesis was to gain a systematic understanding of psychological factors and processes that influence drivers' perceived need for assistance in potential collision situations. To elucidate under which conditions drivers perceive alarms as unnecessary, a theoretical framework of drivers' subjective alarm evaluation was developed. A further goal was to investigate the impact of unnecessary alarms on drivers' responses and acceptance. Four driving simulator studies were carried out to examine the outlined research questions. In line with the hypotheses derived from the theoretical framework, the results suggest that drivers' perceived need for assistance is determined by their retrospective subjective hazard perception. While predictions of conventional FCA systems are exclusively based on physical measurements resulting in a time to collision, human drivers additionally consider their own manoeuvre intentions and those attributed to other road users to anticipate the further course of a potentially critical situation. When drivers anticipate a dissolving outcome of a potential conflict, they perceive the situation as less hazardous than the system. Based on this discrepancy, the system would activate an alarm, while drivers' perceived need for assistance is low. To sum up, the described factors and processes cause drivers to perceive certain alarms as unnecessary. Although drivers accept unnecessary alarms less than useful alarms, unnecessary alarms do not reduce their overall system acceptance. While unnecessary alarms cause moderate driver responses in the short term, the intensity of responses decrease with multiple exposures to unnecessary alarms. However, overall, effects of unnecessary alarms on drivers' alarm responses and acceptance seem to be rather uncritical. This thesis provides insights into human factors that explain when FCAs are perceived as unnecessary.

These blinks are strongly modulated during various cognitive task. However, the precise function of blinking and the reason for their modulation has not been fully understood. In the present work, I investigated the function of spontaneous blinks through various perceptual and cognitive tasks. Previous research has revealed that blinks rates decrease during some tasks but increase during others. When trying to understand these seemingly contradictory results, I observed that blink reduction occurs when one engages with an external input. For instance, a decrease has been observed due to the onset of a stimulus, sensory input processing and attention towards sensory input. However, for activities that do not involve such an engagement, e.g. imagination, daydreaming or creativity, the blink rate has been shown to increase. To follow up on the proposed hypothesis, I distinguished tasks that involve the processing of an external stimulus and tasks that involve disengagement. In the first part of the project, I explored blinking during stimulus engagement. If the probability of blinking is low when engaging with the stimulus, then one should find a reduction in blinks specifically during the time period of processing but not during sensory input per se. To this end, in study 1, I tested the influence of task-relevant information duration on blink timing and additionally manipulated the overall sensory input using a visual and an auditory temporal simultaneity judgement task. The results showed that blinks were suppressed longer for longer periods of relevant information or in other words, blinks occurred at the end of relevant information processing for both the visual and the auditory modality. Since relevance is mediated through top-down processes, I argue that the reduction in blinks is a top-down driven suppression. In studies 2 and 3, I again investigated stimulus processing, but in this case, processing was triggered internally and not based on specific changes in the external input. To this end, I used bistable stimuli, in which the actual physical stimulus remains constant but their perception switches between different interpretations. Studies on the involvement of attention in such bistable perceptual changes indicate that the sensory input is reprocessed before the perceptual switch. The results revealed a reduction in eye blink rates before the report of perceptual switches. Importantly, I was able to decipher that the decrease was not caused by the perceptual switch or the behavioral response but likely started before the internal switch. Additionally, periods between a blink and a switch were longer than interblink intervals, indicating that blinks were followed by a period of stable percept. To conclude, the first part of the project revealed that there is a top-down driven blink suppression during the processing of an external stimulus. In the second part of the project, I extended the idea of blinks marking the disengagement from external processing and tested if blinking is associated with better performance during internally directed processes. Specifically, I investigated divergent thinking, an aspect of creativity, and the link between performance and blink rates as well as the effect of motor restriction. While I could show that motor restriction was the main factor influencing divergent thinking, the relationship between eye blink rates and creative output also depended on restriction. Results showed that higher blink rates were associated with better performance during free movement, but only between subjects. In other words, subjects who had overall higher blink rates scored better in the task, but when they were allowed to sit or walk freely. Within a single subject, trial with higher blink rates were not associated with better performance. Therefore, possibly, people who are able to disengage easily, as indicated by an overall high blink rate, perform better in divergent thinking tasks. However, the link between blink rate and internal tasks is not clear at this point. Indeed, a more complex measurement of blink behavior might be necessary to understand the relationship. In the final part of the project, I aimed to further understand the function of blinks through their neural correlates. I extracted the blink-related neural activity in the primary visual cortex (V1) of existing recordings of three rhesus monkeys during different sensory processing states. I analyzed spike related multi-unit responses, frequency dependent power changes, local field potentials and laminar distribution of activity while the animal watched a movie compared to when it was shown a blank screen. The results showed a difference in blink-related neural activity dependent on the processing state. This difference suggests a state dependent function of blinks. Taken altogether, the work presented in this thesis suggests that eye blinks have an important function during cognitive and perceptual processes. Blinks seem to facilitate a disengagement from the external world and are therefore suppressed during intended processing of external stimuli.}, subject = {Lidschlag}, language = {en} } @article{HoffmannPieczykolanKochetal.2020, author = {Hoffmann, Mareike A. and Pieczykolan, Aleks and Koch, Iring and Huestegge, Lynn}, title = {Two sources of task prioritization: The interplay of effector-based and task order-based capacity allocation in the PRP paradigm}, series = {Attention, Perception, \& Psychophysics}, volume = {82}, journal = {Attention, Perception, \& Psychophysics}, issn = {1943-3921}, doi = {10.3758/s13414-020-02071-6}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235365}, pages = {3402-3414}, year = {2020}, abstract = {When processing of two tasks overlaps, performance is known to suffer. In the well-established psychological refractory period (PRP) paradigm, tasks are triggered by two stimuli with a short temporal delay (stimulus onset asynchrony; SOA), thereby allowing control of the degree of task overlap. A decrease of the SOA reliably yields longer RTs of the task associated with the second stimulus (Task 2) while performance in the other task (Task 1) remains largely unaffected. This Task 2-specific SOA effect is usually interpreted in terms of central capacity limitations. Particularly, it has been assumed that response selection in Task 2 is delayed due to the allocation of less capacity until this process has been completed in Task 1. Recently, another important factor determining task prioritization has been proposed—namely, the particular effector systems associated with tasks. Here, we study both sources of task prioritization simultaneously by systematically combining three different effector systems (pairwise combinations of oculomotor, vocal, and manual responses) in the PRP paradigm. Specifically, we asked whether task order-based task prioritization (SOA effect) is modulated as a function of Task 2 effector system. The results indicate a modulation of SOA effects when the same (oculomotor) Task 1 is combined with a vocal versus a manual Task 2. This is incompatible with the assumption that SOA effects are solely determined by Task 1 response selection duration. Instead, they support the view that dual-task processing bottlenecks are resolved by establishing a capacity allocation scheme fed by multiple input factors, including attentional weights associated with particular effector systems.}, language = {en} }
