(2017): Habit in Personality and Social Psychology. In: Personality and social psychology review : an official journal of the Society for Personality and Social Psychology, Inc 21 (4), S. 389-403. DOI: 10.1177/1088868317720362
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28737111 Abstract: Habits are largely absent from modern social and personality psychology. This is due to outdated perspectives that placed habits in conflict with goals. In modern theorizing, habits are represented in memory as implicit context-response associations, and they guide responding in conjunction with goals. Habits thus have important implications for our field. Emerging research shows that habits are an important mechanism by which people self-regulate and achieve long-term goals. Also, habits change through specific interventions, such as changes in context cues. I speculate that understanding of habits also holds promise for reducing intergroup discrimination and for understanding lay theories of the causes for action. In short, by recognizing habit, the field gains understanding of a central mechanism by which actions persist in daily life. zitiert von 6

(2015): The cue is the key. The relevance of cues and contextual information in the social understanding tasks of the Magdeburg Test of Social Intelligence. In: European Journal of Psychological Assessment 31 (1), S. 38-44. DOI: 10.1027/1015-5759/a000204
DOI: https://doi.org/10.1027/1015-5759/a000204 Abstract: In contrast to former tests, the Magdeburg Test of Social Intelligence measures social understanding with a scenario approach. Each scenario is based on one real target person and includes both social cues and contextual information about this person in different realistic situations. The subjects' task is to understand the given social cues and to judge the target persons' cognitions, emotions, and relationships to other people. However, subjects can potentially use only contextual information instead of social cues or base their judgments equally on both. The present study was aimed at examining the relative contribution of social cues and contextual information. In an experiment (N = 126), the following conditions were manipulated: Participants were given (1) only social cues, (2) only contextual information, or (3) both components. Results showed that social cues played a more important role in this social understanding task than the contextual information.

(2015): When sexual threat cues shape attitudes toward immigrants. The role of insecurity and benevolent sexism. In: Frontiers in psychology 6. DOI: 10.3389/fpsyg.2015.01033
DOI: http://www.ncbi.nlm.nih.gov/pubmed/26283985 Abstract: Drawing on psychological and political science research on individuals' sensitivity to threat cues, the present study examines reactions to political posters that depict male immigrants as a sexual danger. We expect anti-immigrant attitudes to be more strongly predicted by feelings of insecurity or representations of men and women as strong and fragile when individuals are exposed to sexual threat cues than when they are not. Results from two online experiments conducted in Switzerland and Germany largely confirmed these assumptions. Comparing two anti-immigrant posters (general and non-sexual threat vs. sexual threat), Experiment 1 (n = 142) showed that feelings of insecurity were related to an increased support for expelling immigrants from the host country in both cases. However, only in the sexual threat cues condition and among female participants, were perceptions of women as fragile-as measured with benevolent sexism items-related to support for expelling immigrants. Further distinguishing between different forms of violence threat cues, Experiment 2 (n = 181) showed that collective feelings of insecurity were most strongly related to support for expelling immigrants when a male immigrant was presented as a violent criminal. In contrast, benevolent sexist beliefs were related to anti-immigrant stances only when participants were exposed to a depiction of a male immigrant as a rapist. In both cases attitudes were polarized: on the one hand, representations of immigrants as criminals provoked reactance reactions-that is, more positive attitudes-among participants scoring low in insecurity feelings or benevolent sexism. On the other hand, those scoring high in these dimensions expressed slightly more negative attitudes. Overall, by applying social psychological concepts to the study of anti-immigrant political campaigning, the present study demonstrated that individuals are sensitive to specific threat cues in posters.

(2014): Don't do it again! Directed forgetting of habits. In: Psychological science 25 (6), S. 1242-1248. DOI: 10.1177/0956797614526063
DOI: http://www.ncbi.nlm.nih.gov/pubmed/24714574 Abstract: Most daily routines are determined by habits. However, the experienced ease and automaticity of habit formation and execution come at a cost when habits that are no longer appropriate must be overcome. So far, proactive and reactive control strategies that prevent inappropriate habit execution either by preparation or "on the fly" have been identified. Here, we present evidence for a third, retroactive control strategy. In two experiments using the list method of directed forgetting, the accessibility of newly learned and practiced stimulus-response rules was significantly reduced when participants were cued to forget the rules rather than to remember them. The results thus show that directed forgetting, so far observed and investigated only for episodic memory traces, can also be applied to habits. The findings further emphasize the adaptive value of forgetting and can be taken as evidence of a retroactive strategy of habit control. zitiert von 12

(2014): Adolescent-specific patterns of behavior and neural activity during social reinforcement learning. In: Cognitive, affective & behavioral neuroscience 14 (2), S. 683-697. DOI: 10.3758/s13415-014-0257-z
DOI: http://www.ncbi.nlm.nih.gov/pubmed/24550063 Abstract: Humans are sophisticated social beings. Social cues from others are exceptionally salient, particularly during adolescence. Understanding how adolescents interpret and learn from variable social signals can provide insight into the observed shift in social sensitivity during this period. The present study tested 120 participants between the ages of 8 and 25 years on a social reinforcement learning task where the probability of receiving positive social feedback was parametrically manipulated. Seventy-eight of these participants completed the task during fMRI scanning. Modeling trial-by-trial learning, children and adults showed higher positive learning rates than did adolescents, suggesting that adolescents demonstrated less differentiation in their reaction times for peers who provided more positive feedback. Forming expectations about receiving positive social reinforcement correlated with neural activity within the medial prefrontal cortex and ventral striatum across age. Adolescents, unlike children and adults, showed greater insular activity during positive prediction error learning and increased activity in the supplementary motor cortex and the putamen when receiving positive social feedback regardless of the expected outcome, suggesting that peer approval may motivate adolescents toward action. While different amounts of positive social reinforcement enhanced learning in children and adults, all positive social reinforcement equally motivated adolescents. Together, these findings indicate that sensitivity to peer approval during adolescence goes beyond simple reinforcement theory accounts and suggest possible explanations for how peers may motivate adolescent behavior. zitiert von 59

(2013): Emotions as signals of normative conduct. In: Cognition & emotion 27 (8), S. 1395-1404. DOI: 10.1080/02699931.2013.791615
DOI: http://www.ncbi.nlm.nih.gov/pubmed/23650979 Abstract: Social interactions are heavily norm-based and these norms need to be learned. For this, the emotional reactions of other's in response to a norm transgression can serve as signals. We were able to show that when a group responds with anger to a norm transgressing behaviour, participants were better able to correctly infer the norm than when the group responded with sadness or emotional neutrality. We further tested a process-model showing that this inference is based on the participants' understanding of the groups' appraisals of the behaviour. That is, participants who were able to reverse engineer the underlying appraisal of norm-incompatibility from the emotion expressions inferred the norm more readily. Humans as a social species, require efficient means to quickly adapt to new situations and to perform flawlessly in social contexts. Emotion information is one of the instruments that can be used in this quest.

(2013): Simple heuristics in a social world. Social learning: A route to good cue orders. New York, NY: Oxford Univ. Press (Evolution and cognition)
Abstract: Discusses how individuals learn good cue orders in social learning. The process of how people can learn this both individually and socially by exchanging information is outlined. It is hypothesized that information exchange can help boundedly rational individuals efficiently solve the problem of learning which cues are good by the use of various heuristics. Illustrative data from recent experimental research regarding both individuals and groups are discussed. Results showed that individual learning of cue orders was slower than when engaged socially with others, likely due to the participant's imitation of a group's most accurate member. In conclusion, it is argued that an integrative view of both individual and social learning is most relevant when studying the learning of good cue orders.

(2012): Multi-cue contingency detection. In: International Journal of Social Robotics 4 (2), S. 147-161. DOI: 10.1007/s12369-011-0136-5
DOI: https://doi.org/10.1007/s12369-011-0136-5 Abstract: The ability to detect a human’s contingent response is an essential skill for a social robot attempting to engage new interaction partners or maintain ongoing turn-taking interactions. Prior work on contingency detection focuses on single cues from isolated channels, such as changes in gaze, motion, or sound. We propose a framework that integrates multiple cues for detecting contingency from multimodal sensor data in human-robot interaction scenarios. We describe three levels of integration and discuss our method for performing sensor fusion at each of these levels.We perform a Wizard-of-Oz data collection experiment in a turn-taking scenario in which our humanoid robot plays the turn-taking imitation game ’Simon says’ with human partners. Using this data set, which includes motion and body pose cues from a depth and color image and audio cues from a microphone, we evaluate our contingency detection module with the proposed integration mechanisms and show gains in accuracy of our multi-cue approach over single-cue contingency detection.We show the importance of selecting the appropriate level of cue integration as well as the implications of varying the referent event parameter.

(2010): The others. Universals and cultural specificities in the perception of status and dominance from nonverbal behavior. In: Consciousness and cognition 19 (3), S. 762-777. DOI: 10.1016/j.concog.2010.06.006
DOI: http://www.ncbi.nlm.nih.gov/pubmed/20630775 Abstract: The current study analyzes trans-cultural universalities and specificities in the recognition of status roles, dominance perception and social evaluation based on nonverbal cues. Using a novel methodology, which allowed to mask clues to ethnicity and cultural background of the agents, we compared impression of Germans, Americans and Arabs observing computer-animated interactions from the three countries. Only in the German stimulus sample the status roles (employee vs. supervisor) could be recognized above chance level. However we found significant correlations in dominance perception across all countries. Significant correlations were only found for evaluation between German observers and observers from the other two countries. Perceived dominance uniformly predicted the assignment of status-roles in all cultures. Microanalysis of movement behavior further revealed predictive value of specific nonverbal cues for dominance ratings. Results support the hypothesis of universalities in the processing of dominance cues and point to cultural specificities in evaluative responses to nonverbal behavior.

(2010): "Artificial humans": Psychology and neuroscience perspectives on embodiment and nonverbal communication. In: Neural networks : the official journal of the International Neural Network Society 23 (8-9), S. 1077-1090. DOI: 10.1016/j.neunet.2010.06.003
DOI: https://doi.org/10.1016/j.neunet.2010.06.003 Abstract: "Artificial humans", so-called "Embodied Conversational Agents" and humanoid robots, are assumed to facilitate human-technology interaction referring to the unique human capacities of interpersonal communication and social information processing. While early research and development in artificial intelligence (AI) focused on processing and production of natural language, the "new AI" has also taken into account the emotional and relational aspects of communication with an emphasis both on understanding and production of nonverbal behavior. This shift in attention in computer science and engineering is reflected in recent developments in psychology and social cognitive neuroscience. This article addresses key challenges which emerge from the goal to equip machines with socio-emotional intelligence and to enable them to interpret subtle nonverbal cues and to respond to social affordances with naturally appearing behavior from both perspectives. In particular, we propose that the creation of credible artificial humans not only defines the ultimate test for our understanding of human communication and social cognition but also provides a unique research tool to improve our knowledge about the underlying psychological processes and neural mechanisms.

(2009): Testing a social-cognitive model of moral behavior. The interactive influence of situations and moral identity centrality. In: Journal of personality and social psychology 97 (1), S. 123-141. DOI: 10.1037/a0015406
DOI: http://www.ncbi.nlm.nih.gov/pubmed/19586244 Abstract: This article proposes and tests a social-cognitive framework for examining the joint influence of situational factors and the centrality of moral identity on moral intentions and behaviors. The authors hypothesized that if a situational factor increases the current accessibility of moral identity within the working self-concept, then it strengthens the motivation to act morally. In contrast, if a situational factor decreases the current accessibility of moral identity, then it weakens the motivation to act morally. The authors also expected the influence of situational factors to vary depending on the extent to which moral identity was central to a person's overall self-conception. Hypotheses derived from the framework were tested in 4 studies. The studies used recalling and reading a list of the Ten Commandments (Study 1), writing a story using morally laden terms (Study 4), and the presence of performance-based financial incentives (Studies 2 and 3) as situational factors. Participants' willingness to initiate a cause-related marketing program (Study 1), lie to a job candidate during a salary negotiation (Studies 2 and 3), and contribute to a public good (Study 4) were examined. Results provide strong support for the proposed framework. zitiert von: 551

(2009): The effects of degree of acquaintance, plate size, and sharing on food intake. In: Appetite 52 (3), S. 595-602. DOI: 10.1016/j.appet.2009.02.004
DOI: http://www.ncbi.nlm.nih.gov/pubmed/19501755 Abstract: This study examined the effects of degree of acquaintance, plate size, and sharing on the amount of pasta individuals served themselves and subsequently consumed and whether or not they took second helpings. Fifty-seven pairs of female participants ate a meal of pasta; the members of each pair were either friends or strangers. During the meal, they served themselves either from a common serving bowl or from individual serving bowls and onto either small or large plates. The findings indicated that participants who ate with a friend served and consumed more than those who ate with a stranger, and those who shared served and consumed less than those who did not share. However, this sharing effect seemed to occur only when participants ate from small plates. Whether or not participants reported taking second helpings was influenced by all three of the independent variables.

Hertwig, Ralph (2006): Do legal rules rule behavior?. Heuristics and the law. Berlin, Germany. Berlin, Germany: Dahlem University Press (Dahlem workshop reports)
Abstract: Economic analyses of law share an implicit or explicit belief in unbounded rationality. Here two boundedly rational psychological principles are discussed that together provide an alternative explanation for why most people behave in accordance with legal rules most of the time. These principles are the capacity for social learning and the impact of environmental cues and constraints. The ability to observe others' behavior and its consequences helps people conform to behavioral norms without memorizing the legal canon or Miss Manners's rules of etiquette. Environmental and institutional constraints help winnow down the set of actions available to people, and environmental cues suggest which of the available actions are desirable. If people who aspire to live by legal rules, standards, and institutions are to have a chance of doing so, lawmakers must recognize the psychological realities of boundedly rational decision making.
