The results of the first study show that people can easily and confidently relate their experiences with technology to the definitions of force-dynamic events (e.g. "The driver released the handbrake" as an example of restraint removal). The results of the second study show moderate agreement between four expert coders across all ten force-dynamic categories (Cohen's kappa = .59) when re-classifying these episodes. Agreement values for single force-dynamic categories ranged between 'fair' and 'almost perfect', i.e. between kappa = .30 and .95. Agreement with the originally intended classifications of study 1 was higher than the pure inter-coder reliabilities. Single coders achieved an average kappa of .71, indicating substantial agreement. Using more than one coder increased kappas to almost perfect: up to .87 for four coders. A qualitative analysis of the predicted versus the observed number of category confusions revealed that about half of the category disagreement could be predicted from strong overlaps in the definitions of force-dynamic categories. From the quantitative and qualitative results, guidelines are derived to aid the better training of coders in order to increase inter-coder reliability.}, language = {en} } @inproceedings{OPUS4-9740, title = {Media Psychology - "Media Research: Yesterday, Today, and Tomorrow" Proceedings of the 8th Conference of the Media Psychology Division of the German Psychological Society}, editor = {Schwab, Frank and Carolus, Astrid and Brill, Michael and Hennighausen, Christine}, isbn = {978-3-923959-93-8}, doi = {10.25972/OPUS-9740}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-97403}, pages = {105}, year = {2013}, abstract = {The proceedings of the 8th Conference of the Media Psychology Division of the German Psychological Society hosted by the University of Wuerzburg from the 4th until the 6th of September 2013 contains the abstracts of the conference participants.

Therefore, the aim of our study was to analyze the effects of metacognitive prompts on learning processes and outcomes during a computer-based learning task.

Die grundlegende Annahme lautet dabei, dass Marginalien als Kommentar zum Text aufgefasst werden und somit im Vergleich zu intratextuellen Lernhilfen wie {\"U}berschriften oder absatzeinleitenden Makropropositionen zu einer interaktiven und tieferen Verarbeitung der Lerninhalte f{\"u}hren. Als Lernmedium wurden eine hierarchische Hypertextumgebung zum Thema Fragebogenkonstruktion und eine netzf{\"o}rmige Hypertextumgebung zur Bedeutung des Buchdrucks in der Medientheorie eingesetzt. Experiment 1 (N= 41) verglich mittels between-Design die Lernleistung bei Marginalien mit einer Pr{\"a}sentation derselben Makropropositionen als absatzeinleitende Topic-S{\"a}tze und einer Platzierung der Makropropositionen am Absatzende. Die Ergebnisse zeigen, dass absatzweise Marginalien im Vergleich zu absatzeinleitenden Makropropositionen und der Kontrollgruppe zu einem besseren Abschneiden bei geschlossenen Inferenzfragen f{\"u}hren. Hinsichtlich geschlossener Fragen zur Textbasis konnten jedoch die absatzeinleitenden Makropropositionen im Vergleich mit den beiden anderen Bedingungen die besten Ergebnisse erzielen. Experiment 2 (N= 105) verglich den Einfluss von Marginalien mit {\"U}berschriften und einer Kontrollgruppe ohne absatzweise Explikation der Makrostruktur auf das Schreiben einer Zusammenfassung des Lerntextes. Zus{\"a}tzlich wurden erneut geschlossene Inferenzfragen pr{\"a}sentiert. Erg{\"a}nzend wurde das Rezeptionsverhalten mittels Blickbewegungsmessung ermittelt. Dabei zeigten sich signifikante Unterschiede zwischen {\"U}berschriften und Marginalien. Marginalien wurden in der hierarchischen Hypertextumgebung allgemein seltener gelesen als {\"U}berschriften und zeigten auch hinsichtlich der Anzahl der strategischen Rezeptionen und der absatzeinleitenden Rezeption geringere Werte. Einzig nach der Rezeption des zugeh{\"o}rigen Absatzes wurden Marginalien h{\"a}ufiger konsultiert als {\"U}berschriften. Diese Unterschiede gingen einher mit signifikanten Einbußen der Lernleistung der Marginalienbedingung im Vergleich zur {\"U}berschriftenbedingung. So erinnerten Lerner mit Marginalien weniger explizite Makropropositionen des Lerntextes, weniger Fakteninformationen, sowie weniger Inhalte verschiedener Hypertextknoten und bildeten außerdem weniger eigene Makropropositionen. Hinsichtlich der letzten beiden Variablen war die Marginalienbedingung sogar der Kontrollbedingung unterlegen. Experiment 3 (N = 54) verwendete im Gegensatz zu den Experimenten 1 und 2 einen netzf{\"o}rmig organisierten Hypertext mit embedded Links anstelle eines Navigationsmen{\"u}s. Die untersuchten Versuchsbedingungen sowie die Messung der Lernleistung waren jedoch analog zu Experiment 1. Auch hier konnte ein Effekt von Marginalien auf die Inferenzleistung nachgewiesen werden. Allerdings schnitten Marginalien nur besser als die absatzeinleitenden Makropropositionen ab, wohin-gegen kein Unterschied zur Kontrollbedingung festgestellt werden konnten. Hinsichtlich der Leistung bei geschlossenen Faktenfragen konnte die {\"U}berlegenheit absatzeinleitender Makropropositionen gegen{\"u}ber den anderen beiden Pr{\"a}sentationsformen der Makrostruktur erneut best{\"a}tigt werden. Experiment 4 (N= 75) verglich analog zu Experiment 2 unter Verwendung der netzf{\"o}rmigen Lernumgebung aus Experiment 3 erneut den Einfluss von Marginalien, {\"U}berschriften und einer Kontrollbedingung ohne explizite absatzweise Makropropositionen auf das Schreiben einer Zusammenfassung sowie die Beantwortung geschlossener Inferenzfragen. Auch die Blickbewegungsmessung kam wieder zum Einsatz. Die Ergebnisse von Experiment 2 konnten jedoch nicht best{\"a}tigt werden. Es fanden sich keine signifikanten Unterschiede hinsichtlich der Lernleistung zwischen den drei Versuchsbedingungen und auch hinsichtlich des Rezeptionsverhaltens konnte eine Angleichung von Marginalien und {\"U}berschriften festgestellt werden. Hinsichtlich der Lernleistung wird angenommen, dass die embedded Links in Kombination mit der Instruktion, eine Zusammenfassung zu schreiben mit den {\"U}berschriften und den Marginalien, die jedoch im Vergleich zu Experiment 2 fast vollst{\"a}ndig wie {\"U}berschriften genutzt wurden, interferiert haben und somit eine Hemmung dieser Lernhilfen stattgefunden hat. Anhand der vier durchgef{\"u}hrten Experimente wird gefolgert, dass Marginalien als Explikation der lokalen Makrostruktur sowohl bei hierarchisch strukturiertem Hypertext als auch bei netzf{\"o}rmig organisiertem Hypertext unter der Instruktion eines verstehenden Lernens eine Verbesserung der Inferenzleistung bewirken k{\"o}nnen.

The impact of affective states can be both directly on the learning performance and indirectly mediated via, for example, motivational processes. Positive activating affect is often associated with increased memory skills as well as advantages in creative problem solving. Negative activating affect on the other hand is regarded to impair learning outcomes because of promoting task-irrelevant thinking. While these relationships were found to be relatively stable in correlation studies, causal relationships have been examined rarely so far. This dissertation aims to investigate the effects of positive and negative affective states in multimedia learning settings and to identify potential moderating factors. Therefore, three experimental empirical studies on university students were conducted. In Experiment 1, N = 57 university students were randomly allocated to either a positive or negative affect induction group. Affects were elicited using short film clips. After a 20-minute learning phase in a hypertext-based multimedia learning environment on "functional neuroanatomy" the learners' knowledge as well as transfer performance were measured. It was assumed that inducing positive activating affect should enhance learning performance. Eliciting negative activating affect on the other hand should impair learning performance. However, it was found that the induction of negative activating affect prior to the learning phase resulted in slight deteriorations in knowledge. Contrary to the assumptions, inducing positive activating affect before the learning phase did not improve learning performance. Experiment 2 induced positive activating affect directly during learning. To induce affective states during the entire duration of the learning phase, Experiment 2 used an emotional design paradigm. Therefore, N = 111 university students were randomly assigned to learn either in an affect inducing multimedia learning environment (use of warm colours and round shapes) or an affectively neutral counterpart (using shades of grey and angular shapes) on the same topic as in Experiment 1. Again, knowledge as well as transfer performance were measured after learning for 20 minutes. In addition, positive and negative affective states were measured before and after learning. Complex interaction patterns between the treatment and initial affective states were found. Specifically, learners with high levels of positive affect before learning showed better transfer performance when they learned in the affect inducing learning environment. Regarding knowledge, those participants who reported high levels of negative activating affect prior to the learning period performed worse. However, the effect on knowledge did not occur for those students learning in the affect inducing learning environment. For knowledge, the treatment therefore protected against poorer performance due to high levels of negative affective states. Results of Experiment 2 showed that the induction of positive activating affect influenced learning performance positively when taking into account affective states prior to the learning phase. In order to confirm these interaction effects, a conceptual replication of the previous experiment was conducted in Experiment 3. Experiment 3 largely retained the former study design, but changed the learning materials and tests used. Analogous to Experiment 2, N = 145 university students learning for 20 minutes in either an affect inducing or an affectively neutral multimedia learning environment on "eukaryotic cell". To strengthen the treatment, Experiment 3 also used anthropomorphic design elements to induce affective states next to warm colours and round shapes. Moreover, in order to assess the change in affective states more exactly, an additional measurement of positive and negative affective states after half of the learning time was inserted. Knowledge and transfer were assessed again to measure learning performance. The learners' memory skills were used as an additional learning outcome. To control the influence of potential confounding variables, the participants' general and current achievement motivation as well as interest, and emotion regulation skills were measured. Contrary to the assumptions, Experiment 3 could not confirm the interaction effects of Experiment 2. Instead, there was a significant impact of positive activating affect prior to the learning phase on transfer, irrespective of the learners' group affiliation. This effect was further independent of the control variables that were measured. Nevertheless, the results of Experiment 3 fit into the picture of findings regarding "emotional design" in hypermedia learning settings. To date, the few publications that have used this approach propose heterogeneous results, even when using identical materials and procedures.}, subject = {Affekt}, language = {en} } @phdthesis{Hennighausen2016, author = {Hennighausen, Anna Christine}, title = {Costly signaling with mobile devices: An evolutionary psychological perspective on smartphones}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-141049}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2016}, abstract = {In the last decade, mobile device ownership has largely increased. In particular, smartphone ownership is constantly rising (A. Smith, 2015; Statista, 2016a), and there is a real hype for luxury brand smartphones (Griffin, 2015). These observations raise the question of which functions smartphones serve in addition to their original purposes of making and receiving calls, searching for information, and organizing. Beyond these obvious functions, studies suggest that smartphones express fashion, lifestyle, and one's economic status (e.g., B{\o}dker et al., 2009; Statista, 2016b; Vanden Abeele, Antheunis, \& Schouten, 2014). Specifically, individuals seem to purchase and use conspicuous luxury brand smartphones to display and enhance status (D. Kim et al., 2014; M{\"u}ller-Lietzkow et al., 2014; Suki, 2013). But how does owning a conspicuous, high-status smartphone contribute to status, and which benefits may these status boosts provide to their owners? From an evolutionary perspective, status carries a lot of advantages, particularly for males; high status grants them priority access to resources and correlates with their mating success (van Vugt \& Tybur, 2016). In this sense, research suggests that men conspicuously display their cell phones to attract mates and to distinguish themselves from rivals (Lycett \& Dunbar, 2000). In a similar vein, evolutionarily informed studies on conspicuous consumption indicate that the purchase and display of conspicuous luxuries (including mobile phones and smartphones) relate to a man's interest in uncommitted sexual relationships and enhance his desirability as a short-term mate (Hennighausen \& Schwab, 2014; Saad, 2013; Sundie et al., 2011). Drawing on these findings, this doctoral dissertation investigated how a man is perceived given that he is an owner of a high-status (vs. nonconspicuous, low-status) smartphone as a romantic partner and male rival. This was done in three experiments. In addition, it was examined how male conspicuous consumption of smartphones interacted with further traits that signal a man's mate quality, namely facial attractiveness (Studies 1 and 2) and social dominance (Study 3). Study 1 revealed that men and women perceived a male owner of a conspicuous smartphone as a less desirable long-term mate and as more inclined toward short-term mating. Study 2 replicated these results and showed that men and women assigned traits that are associated with short-term mating (e.g., low loyalty, interest in flirts, availability of tangible resources) to a male owner of a conspicuous smartphone and perceived him as a stronger male rival and mate poacher, and less as a friend. The results of Study 2 further suggested that specifically more attractive men might benefit from owning a conspicuous smartphone in a short-term mating context and might be hence considered as stronger male rivals. Study 3 partially replicated the findings of Studies 1 and 2 pertaining to the effects of owning a conspicuous smartphone. Study 3 did not show different effects of conspicuous consumption of smartphones on perceptions of a man dependent on the level of his social dominance. To conclude, the findings of this doctoral dissertation suggest that owning a conspicuous, high-status smartphone might not only serve proximate functions (e.g., making and receiving calls, organization) but also ultimate functions, which relate to mating and reproduction. The results indicate that owning a conspicuous smartphone might yield benefits for men in a short-term rather than in a long-term mating context. Furthermore, more attractive men appear to benefit more from owning a conspicuous smartphone than less attractive men. These findings provide further insights into the motivations that underlie men's purchases and displays of conspicuous, high-status smartphones from luxury brands that reach beyond the proximate causes frequently described in media and consumer psychological research. By applying an evolutionary perspective, this doctoral dissertation demonstrates the power and utility of this research paradigm for media psychological research and shows how combining a proximate and ultimate perspective adds to a more profound understanding of smartphone phenomena.}, subject = {Verbraucher}, language = {en} } @article{GrundgeigerAlbertReinhardtetal.2016, author = {Grundgeiger, T. and Albert, M. and Reinhardt, D. and Happel, O. and Steinisch, A. and Wurmb, T.}, title = {Real-time tablet-based resuscitation documentation by the team leader: evaluating documentation quality and clinical performance}, series = {Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine}, volume = {24}, journal = {Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine}, number = {51}, doi = {10.1186/s13049-016-0242-3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-146582}, year = {2016}, abstract = {Background Precise and complete documentation of in-hospital cardiopulmonary resuscitations is important but data quality can be poor. In the present study, we investigated the effect of a tablet-based application for real-time resuscitation documentation used by the emergency team leader on documentation quality and clinical performance of the emergency team. Methods Senior anaesthesiologists either used the tablet-based application during the simulated resuscitation for documentation and also used the application for the final documentation or conducted the full documentation at the end of the scenario using the local hospital information system. The latter procedure represents the current local documentation method. All scenarios were video recorded. To assess the documentation, we compared the precision of intervention delivery times, documentation completeness, and final documentation time. To assess clinical performance, we compared adherence to guidelines for defibrillation and adrenaline administration, the no-flow fraction, and the time to first defibrillation. Results The results showed significant benefits for the tablet-based application compared to the hospital information system for precision of the intervention delivery times, the final documentation time, and the no-flow fraction. We observed no differences between the groups for documentation completeness, adherence to guidelines for defibrillation and adrenaline administration, and the time to first defibrillation.

Therefore, it may be necessary to consider explicitly the conditions under which a prompt is beneficial for a student, i.e., so-called adaptive scaffolding. The current study aims to (i) classify the effectiveness of prompts on regulatory behavior, (ii) investigate the correspondence of the classification with learning outcome, and (iii) discover the conditions under which prompts induce regulatory activities (i.e., the proper temporal positioning of prompts). The think-aloud data of an experiment in which metacognitive prompts supported the experimental group (n = 35) was used to distinguish between effective and non-effective prompts. Students' activities preceding the prompt presentation were analyzed using data mining and process mining techniques. The results indicate that approximately half of the presented prompts induced metacognitive learning activities as expected. Moreover, the number of induced monitoring activities correlates positively with transfer performance. Finally, the occurrence of orientation and monitoring activities, which are not well-embedded in the course of learning, increases the effectiveness of a presented prompt.

However, these studies have yet neglected to investigate the function of male conspicuous consumption in same-sex competition.

An 2 (intrasexual competition context vs. control) × 2 (conspicuous luxury vs. inconspicuous nonluxury) between-subjects experimental study conducted with an Amazon Mechanical Turk sample (N = 160) revealed that men reported both higher liking of and an intent to purchase a conspicuous luxury car compared to an inconspicuous nonluxury car due to increased feelings of social status. This effect was stronger in the intrasexual competition than in the control context. An additional perception study using a single-factor between-subjects design (conspicuous luxury vs. inconspicuous nonluxury car) among German men (N = 405) indicated that male participants rated a man who displayed a conspicuous luxury car more as a rival and mate poacher and less as a friend.

Thereby, the focus lies on how disfluency can be used to improve metacognitive monitoring (i.e., students` judgments during the learning process). Improving metacognitive monitoring is important in educational contexts in order to foster performance. Theories about metacognition and self-regulated learning suppose that monitoring affects control and performance. Accurate monitoring is necessary to initiate adequate control and better performance. However, previous research shows that students are often not able to accurately monitor their learning with meaningful text material. Inaccurate monitoring can result in inadequate control and low performance. One reason for inaccurate monitoring is that students use cues for their judgments that are not valid predictors of their performance. Because fluency might be such a cue, the first aim of this thesis is to investigate under which conditions fluency is used as a cue for judgments during the learning process. A fluent text is easy to process and, hence, it should be judged as easy to learn and as easy to remember. Inversely, a disfluent text is difficult to process, for example because of a disfluent font type (e.g., Mistral) or because of deleted letters (e.g., l_tt_rs). Hence, a disfluent text should be judged as difficult to learn and as difficult to remember. This assumption is confirmed when students learn with both fluent and disfluent material. When fluency is manipulated between persons, fluency seems to be less obvious as a cue for judgments. However, there are only a few studies that investigated the effects of fluency on judgments when fluency is manipulated between persons. Results from Experiment 1 (using deleted letters for disfluent text) and from Experiment 4 (using Mistral for disfluent text) in this thesis support the assumption that fluency is used as a cue for judgments in between-person designs. Thereby, however, the interplay with the type of judgment and the learning stage seems to matter. Another condition when fluency affects judgments was investigated in Experiment 2 and 3. The aim of these experiments was to investigate if disfluency leads to analytic monitoring and if analytic monitoring sustains for succeeding fluent material. If disfluency activates analytic monitoring that remains for succeeding fluent material, fluency should no longer be used as a cue for judgments. Results widely support this assumption for deleted letters (Experiment 2) as well as for the font type Mistral (Experiment 3). Thereby, again the interplay between the type of judgment and the learning stage matters. Besides the investigation of conditions when fluency is used as a cue for different types of judgments during the learning process, another aim of this thesis is to investigate if disfluency leads to accurate monitoring. Results from Experiment 3 and 4 support the assumption that Mistral can reduce overconfidence. This is the case when fluency is manipulated between persons or when students first learn with a fluent and then with a disfluent text. Dependent from the type of judgment and the learning stage, disfluency can lead even to underconfidence or to improved relative monitoring accuracy (Experiment 4). Improving monitoring accuracy is only useful when monitoring is implemented into better control and better performance. The effect of monitoring accuracy on control and performance was in the focus of Experiment 4. Results show that accurate monitoring does not result in improved control and performance. Thus, further research is required to develop interventions that do not only improve monitoring accuracy but that also help students to implement accurate monitoring into better control and performance. Summing up, the aim of this thesis is to investigate under which conditions fluency is used as a cue for judgments during the learning process, how disfluency can be used to improve monitoring accuracy, and if improved monitoring accuracy leads to improved performance. By connecting metacognition research and fluency research, further theories about metacognition and theories about fluency are specified. Results show that not only the type of fluency and the design, but also the type of judgment, the type of monitoring accuracy, and the learning stage should be taken into account. Understanding conditions that affect the interplay between metacognitive processes and performance as well as understanding the underlying mechanisms is necessary to enable systematic research and to apply findings into educational settings.}, subject = {Metakognition}, language = {en} } @inproceedings{OPUS4-14713, title = {Research Network on Methodology for the Analysis of Social Interaction.

Often, designers focus on aesthetic properties of color, but neglect that it also carries meaning and entails profound psychological consequences. Color psychology, filling this gap, is in its infancy, and lacks a theoretical approach that predicts and explains color-meaning associations shared by a large group of people in a large variety of contexts. To amend this situation, this work develops Conceptual Metaphor Theory of Color (CMToC), which predicts and explains cross-cultural and experience-based semantic color associations. The theory is based on the idea from cognitive linguistics that the study of metaphorical language provides valuable insights into our mental models involving color. A discussion of three types of metaphors that cover associations with physical and abstract concepts in light of existing empirical evidence provides the basis for deriving empirical research questions. The first research question addresses the use of color for conveying physical information like weight in user interfaces. The results of four online surveys involving a total of 295 German and Japanese participants show the relative impact of hue, saturation and brightness for associations with 16 physical properties. Two thirds of these color associations were correctly predicted by CMToC. Participants frequently matched physical properties to colors based on sensorimotor correspondences and participants of both cultures did not considerably vary in their performance. The second research question addresses the use of color for conveying abstract information like importance in user interfaces. In one experimental study, a total of 75 German and Japanese participants validated color-to-abstract mappings in form of color population stereotypes like important is dark. The majority of these color associations (86\%) were correctly predicted by CMToC. Again, participants of both cultures did not considerably vary in their performance. The third research question addresses whether predicted color associations with physical and abstract information are processed automatically as a precondition for intuitive use. The results of three studies involving a total of 85 German and Japanese participants show on the example of temperature that color automatically influences the identification speed of related physical properties, but not vice versa. Color and abstract information were not automatically associated. As a result of these studies it can be concluded that predictions of CMToC are cross-culturally valid for user interface design. Derived implicit associations with physical properties and explicit associations with abstract concepts can inform design decisions in both hard- and software user interface design.}, subject = {Softwareergonomie}, language = {en} } @phdthesis{Sonnenberg2017, author = {Sonnenberg, Christoph}, title = {Analyzing Technology-Enhanced Learning Processes: What Can Process Mining Techniques Contribute to the Evaluation of Instructional Support?}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-152354}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2017}, abstract = {The current dissertation addresses the analysis of technology-enhanced learning processes by using Process Mining techniques. For this purpose, students' coded think-aloud data served as the measurement of the learning process, in order to assess the potential of this analysis method for evaluating the impact of instructional support. The increasing use of digital media in higher education and further educational sectors enables new potentials. However, it also poses new challenges to students, especially regarding the self-regulation of their learning process. To help students with optimally making progress towards their learning goals, instructional support is provided during learning. Besides the use of questionnaires and tests for the assessment of learning, researchers make use increasingly of process data to evaluate the effects of provided support. The analysis of observed behavioral traces while learning (e.g., log files, eye movements, verbal reports) allows detailed insights into the student's activities as well as the impact of interventions on the learning process. However, new analytical challenges emerge, especially when going beyond the analysis of pure frequencies of observed events. For example, the question how to deal with temporal dynamics and sequences of learning activities arises. Against this background, the current dissertation concentrates on the application of Process Mining techniques for the detailed analysis of learning processes. In particular, the focus is on the additional value of this approach in comparison to a frequency-based analysis, and therefore on the potential of Process Mining for the evaluation of instructional support. An extensive laboratory study with 70 university students, which was conducted to investigate the impact of a support measure, served as the basis for pursuing the research agenda of this dissertation. Metacognitive prompts supported students in the experimental group (n = 35) during a 40-minute hypermedia learning session; whereas the control group (n = 35) received no support. Approximately three weeks later, all students participated in another learning session; however, this time all students learned without any help. The participants were instructed to verbalize their learning activities concurrently while learning. In the three analyses of this dissertation, the coded think aloud data were examined in detail by using frequency-based methods as well as Process Mining techniques. The first analysis addressed the comparison of the learning activities between the experimental and control groups during the first learning session. This study concentrated on the research questions whether metacognitive prompting increases the number of metacognitive learning activities, whether a higher number of these learning activities corresponds with learning outcome (mediation), and which differences regarding the sequential structure of learning activities can be revealed. The second analysis investigated the impact of the individual prompts as well as the conditions of their effectiveness on the micro level. In addition to Process Mining, we used a data mining approach to compare the findings of both analysis methods. More specifically, we classified the prompts by their effectiveness, and we examined the learning activities preceding and following the presentation of instructional support. Finally, the third analysis considered the long-term effects of metacognitive prompting on the learning process during another learning session without support. It was the key objective of this study to examine which fostered learning activities and process patterns remained stable during the second learning session. Overall, all three analyses indicated the additional value of Process Mining in comparison to a frequency-based analysis. Especially when conceptualizing the learning process as a dynamic sequence of multiple activities, Process Mining allows identifying regulatory loops and crucial routing points of the process. These findings might contribute to optimizing intervention strategies. However, before drawing conclusions for the design of instructional support based on the revealed process patterns, additional analyses need to investigate the generalizability of results. Moreover, the application of Process Mining remains challenging because guidelines for analytical decisions and parameter settings in technology-enhanced learning context are currently missing. Therefore, future studies need to examine further the potential of Process Mining as well as related analysis methods to provide researchers with concrete recommendations for use. Nevertheless, the application of Process Mining techniques can already contribute to advance the understanding of the impact of instructional support through the use of fine-grained process data.}, subject = {Selbstgesteuertes Lernen}, language = {en} } @article{vonMammenWagnerKnoteetal.2017, author = {von Mammen, Sebastian Albrecht and Wagner, Daniel and Knote, Andreas and Taskin, Umut}, title = {Interactive simulations of biohybrid systems}, series = {Frontiers in Robotics and AI}, volume = {4}, journal = {Frontiers in Robotics and AI}, issn = {2296-9144}, doi = {10.3389/frobt.2017.00050}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-195755}, year = {2017}, abstract = {In this article, we present approaches to interactive simulations of biohybrid systems. These simulations are comprised of two major computational components: (1) agent-based developmental models that retrace organismal growth and unfolding of technical scaffoldings and (2) interfaces to explore these models interactively. Simulations of biohybrid systems allow us to fast forward and experience their evolution over time based on our design decisions involving the choice, configuration and initial states of the deployed biological and robotic actors as well as their interplay with the environment. We briefly introduce the concept of swarm grammars, an agent-based extension of L-systems for retracing growth processes and structural artifacts. Next, we review an early augmented reality prototype for designing and projecting biohybrid system simulations into real space. In addition to models that retrace plant behaviors, we specify swarm grammar agents to braid structures in a self-organizing manner. Based on this model, both robotic and plant-driven braiding processes can be experienced and explored in virtual worlds. We present an according user interface for use in virtual reality. As we present interactive models concerning rather diverse description levels, we only ensured their principal capacity for interaction but did not consider efficiency analyzes beyond prototypic operation. We conclude this article with an outlook on future works on melding reality and virtuality to drive the design and deployment of biohybrid systems.}, language = {en} } @article{MuenchowMengelkampBannert2017, author = {M{\"u}nchow, Hannes and Mengelkamp, Christoph and Bannert, Maria}, title = {The better you feel the better you learn: do warm colours and rounded shapes enhance learning outcome in multimedia learning?}, series = {Education Research International}, volume = {2017}, journal = {Education Research International}, doi = {10.1155/2017/2148139}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-158566}, pages = {2148139}, year = {2017}, abstract = {The aim of the present study was to examine whether fostering positive activating affect during multimedia learning enhances learning outcome. University students were randomly assigned to either a multimedia learning environment designed to induce positive activating affect through the use of "warm" colours and rounded shapes () or an affectively neutral environment that used achromatic colours and sharp edges (). Participants learned about the topic of functional neuroanatomy for 20 minutes and had to answer several questions for comprehension and transfer afterwards. Affective states as well as achievement goal orientations were investigated before and after the learning phase using questionnaires. The results show that participants in the affectively positive environment were superior in comprehension as well as transfer when initial affect was strong. Preexperimental positive affect was therefore a predictor of comprehension and a moderator for transfer. Goal orientations did not influence these effects. The findings support the idea that positive affect, induced through the design of the particular multimedia learning environment, can facilitate performance if initial affective states are taken into account.}, language = {en} } @phdthesis{Ruth2018, author = {Ruth, Nicolas}, title = {Gute Musik.

Such a desirable difficulty is generation, e.g., filling in deleted letters in a deleted letter text. Likewise, letter deletion is a manipulation of processing fluency: A deleted letter text is more difficult to process than an intact text. Disfluency theory also supposes that disfluency initiates analytic processes and thus, improves performance. However, performance is often not affected but, rather, monitoring is affected. The aim of this study is to propose a specification of the effects of disfluency as a desirable difficulty: We suppose that mentally filling in deleted letters activates analytic monitoring but not necessarily analytic cognitive processing and improved performance. Moreover, once activated, analytic monitoring should remain for succeeding fluent text. To test our assumptions, half of the students (n = 32) first learned with a disfluent (deleted letter) text and then with a fluent (intact) text. Results show no differences in monitoring between the disfluent and the fluent text. This supports our assumption that disfluency activates analytic monitoring that remains for succeeding fluent text. When the other half of the students (n = 33) first learned with a fluent and then with a disfluent text, differences in monitoring between the disfluent and the fluent text were found. Performance was significantly affected by fluency but in favor of the fluent texts, and hence, disfluency did not activate analytic cognitive processing. Thus, difficulties can foster analytic monitoring that remains for succeeding fluent text, but they do not necessarily improve performance. Further research is required to investigate how analytic monitoring can lead to improved cognitive processing and performance.}, language = {en} } @article{SchwabHennighausenAdleretal.2018, author = {Schwab, Frank and Hennighausen, Christine and Adler, Dorothea C. and Carolus, Astrid}, title = {Television Is Still "Easy" and Print Is Still "Tough"?

Since the introduction of AIME, this concept appears to have vanished. To obtain a clearer picture of where the theory of AIME has diffused, we conducted a literature search focusing on the period 1985-2015. We examined scientific articles (N = 244) that cite Salomon (1984) and content-analyzed their keywords. Based on these keywords, we identified seven content clusters: affect and motivation, application fields, cognition and learning, education and teaching, media technology, learning with media technology, and methods. We present selected works of each content cluster and describe in which research field the articles had been published. Results indicate that AIME was most commonly (but not exclusively) referred to in the area of educational psychology indicating its importance regarding learning and education, thereby investigating print and TV, as well as new media. From a methodological perspective, research applied various research methods (e.g., longitudinal studies, experimental designs, theoretical analysis) and samples (e.g., children, college students, low income families).

Previous studies showed that recipients temporarily change in line with a story and its characters (assimilation). Conversely, assimilation might be less likely when recipients are less identified with story protagonists or less transported into a story by comparing themselves with a story character. This may lead to changes, which are opposite to a story and its characters (contrast). In two experiments, we manipulated transportation and experience taking via two written reviews (Experiment 1; N = 164) and by varying the perspective of the story's narrator (Experiment 2; N = 79) of a short story about a negligent student. Recipients' self-ratings in comparison to others, motives, and problem-solving behavior served as dependent variables. However, neither the review nor the perspective manipulation affected transportation or experience taking while reading the story. Against our expectations, highly transported recipients (in Study 1) and recipients with high experience taking (in Study 2) showed more persistency working on an anagram-solving task, even when controlling for trait conscientiousness.
