Expression influences the recognition of familiar faces

Face recognition has been assumed to be independent of facial expression. We used familiar and unfamiliar faces that were morphed from a happy to an angry expression within a given identity. Participants performed speeded two-choice decisions according to whether or not a face was familiar. Consistent with earlier findings, reaction times for classifications of unfamiliar faces were independent of facial expressions. In contrast, expression clearly influenced the recognition of familiar faces. with fastest recognition for moderately happy expressions. This suggests that representations of familiar faces for recognition preserve some information about typical emotional expressions.     

When immigrant groups “misbehave”: The influence of perceived deviant behavior on increased threat and discriminatory intentions and the moderating role of right‐wing authoritarianism

In two studies, we tested the relationship between non‐immigrant individuals' perceptions of deviant behavior carried out by Muslims and foreigners and discriminatory intentions towards these outgroups. Based on a longitudinal and a representative cross‐sectional sample, we showed that two different types of perceived deviant behavior (Study 1, Muslims' unwillingness to integrate; and Study 2, foreigners' hostility towards the non‐immigrant majority group) are related to increased intergroup threat, which in turn is related to increased intentions to show passive discrimination (i.e., avoidance) towards these outgroups. In line with theorizing about an increased sensitivity for threat in authoritarian individuals, the relationship between perceptions of deviant behavior and threat was especially strong among high authoritarian individuals. Theoretical and practical implications of our results are discussed.     

The Curriculum as a Standard of Public Education

This contribution first searches for historical and empirical evidence for whether and how curricula act or acted as a measure of public education. The problem is explicated on account of a short history of curriculum work and distinguished in a analytical, a political, programmatical and practical discourse of curriculum work. Curriculum work always underlies premises of planning, learning and effects. Three models are finally developed and brought in touch with the different discourses. Curriculum work proves to be an attempt to make publicly acceptable the empirically impossible accountability of schools.     

Enhancing exposure-based therapy from a translational research perspective

Combining an effective psychological treatment with conventional anxiolytic medication is typically not more effective than unimodal therapy for treating anxiety disorders. However, recent advances in the neuroscience of fear reduction have led to novel approaches for combining psychological therapy and pharmacological agents. Exposure-based treatments in humans partly rely on extinction to reduce the fear response in anxiety disorders. Animal studies have shown that D-cycloserine (DCS), a partial agonist at the glycine recognition site of the glutamatergic N-methyl-D-aspartate receptor facilitates extinction learning. Similarly, recent human trials have shown that DCS enhances fear reduction during exposure therapy of some anxiety disorders. This article discusses the biological and psychological mechanisms of extinction learning and the therapeutic value of DCS as an augmentation strategy for exposure therapy. Areas of future research will be identified.     

Preference-consistent evaluation of information in the hidden profile paradigm: beyond group-level explanations for the dominance of shared information in group decisions

Common explanations for the failure of groups to solve so-called hidden profiles focus on group processes, namely insufficient discussion of unshared information and premature consensus on a suboptimal alternative. As 2 experiments show, even in the absence of such group processes, hidden profiles are hardly ever solved. In Experiment 1, participants first received individual information about a personnel selection task and then read a group discussion protocol containing full information exchange. If the individual information was misleading (hidden profile), most participants failed to detect the correct alternative. In Experiment 2, it was determined that this effect is due to preference-consistent evaluation of information that constitutes an individual-level process mediating the failure of group members to solve hidden profiles.     

Adding emotionality to seductive details—Consequences for learning?

According to the seductive detail effect, adding interesting but irrelevant information (i.e., seductive details) can be detrimental to learning success. In this study, it was explored within two experiments whether the valence of text‐based seductive details might affect learning outcomes differently. For Experiments 1 and 2, we pretested text‐based seductive details for their emotional valence (n = 32 or n = 25 students, respectively). For the main studies of Experiments 1 (n = 105) and 2 (n = 131), university students were randomly assigned to one of four conditions that varied with respect to the presence of seductive details and their emotional valence (no vs. positive vs. negative vs. neutral). Unexpectedly, results revealed in both experiments no seductive details effect and also no differences between the three seductive detail conditions for the used learning outcome measures retention and transfer. Possible reasons for these findings and their implications are discussed.     

Updating an object’s orientation and location during nonvisual navigation: A comparison between two processing modes

In the present study, we compared the effects of two processing modes on the updating of the location and orientation of a previously viewed object in space during a guided walk without vision. In Experiment 1, in order to measure the error for initial perception of object’s orientation, 12 subjects rotated a miniature model until it matched the memorized orientation of its counterpart object in space. In Experiment 2, they attempted either to keep track of the object continuously (in the object-centered [OC] task) or to estimate the object’s perspective only at the terminal vantage point given the trajectory they walked (in the trajectory-centered [TC] task). Subjects indicated the location of the object by facing it, and then rotated the model in order to indicate its orientation from the new vantage point. Results showed that, with respect to the TC mode, the OC mode induced a slowdown of the subjects’ self-paced locomotion velocity for both linear and angular movements, and a decrease of the latencies as well as smaller absolute errors for the orientation-of-the-object response. Mean signed errors on object’s orientation were equivalent for both processing modes, suggesting that the latter induced different allocations of processing resources on a common representation of space updated by “path integration.”
