Use of position and feature cues in discrimination learning by the whiptail lizard (Cnemidophorus inornatus)

Animals use a variety of cue types to locate and discriminate objects. The ease with which particular cue types are learned varies across species and context. An enormous literature contains comparisons of spatial cue use to use of other cue types, but few experiments examine the ease with which various nonspatial cues are learned. In addition, few studies have examined cue use in reptiles. Thus, the authors compared whiptail lizards' (Cnemidophorus inornatus) ability to learn and reverse a discrimination using either position (left or right) or visual feature cues. Lizards learned and reversed the task using position cues faster and with greater accuracy than using feature cues.     

Forgiveness and collective guilt assignment to historical perpetrator groups depend on level of social category inclusiveness

The authors examined how categorization influences victimized group members' responses to contemporary members of a historical perpetrator group. Specifically, the authors tested whether increasing category inclusiveness--from the intergroup level to the maximally inclusive human level--leads to greater forgiveness of a historical perpetrator group and decreased collective guilt assignment for its harmdoing. Among Jewish North Americans (Experiments 1, 2, and 4) and Native Canadians (Experiment 3) human-level categorization resulted in more positive responses toward Germans and White Canadians, respectively, by decreasing the uniqueness of their past harmful actions toward the in-group. Increasing the inclusiveness of categorization led to greater forgiveness and lessened expectations that former out-group members should experience collective guilt compared with when categorization was at the intergroup level. Discussion focuses on obstacles that are likely to be encountered on the road to reconciliation between groups that have a history of conflictual relations.     

Feeling Hopeful Inspires Support for Social Change

Hope is an emotion that has been implicated in social change efforts, yet little research has examined whether feeling hopeful actually motivates support for social change. Study 1 (N = 274) confirmed that hope is associated with greater support for social change in two countries with different political contexts. Study 2 (N = 165) revealed that hope predicts support for social change over and above other emotions often investigated in collective action research. Study 3 (N = 100) replicated this finding using a hope scale and showed the effect occurs independent of positive mood. Study 4 (N = 58) demonstrated experimentally that hope motivates support for social change. In all four studies, the effect of hope was mediated by perceived efficacy to achieve social equality. This research confirms the motivating potential of hope and illustrates the power of this emotion in generating social change.     

Internal control beliefs and reference frame concurrently impact early performance monitoring ERPs

This study investigated the impact of criterion-based vs. social reference frames on behavioural and neural correlates of performance monitoring while taking individual differences in control beliefs into account. We conducted two experiments administering a time estimation task in which feedback was either delivered pertaining to participants’ own performance (nonsocial/criterion-based reference) or to the performance of a reference group of previous participants (social reference). In Experiment 1, 34 male volunteers participated. To test generalizability of the observed results to both sexes/genders, we recruited 36 female volunteers for Experiment 2. P2 and P300 amplitudes were generally larger in social than in nonsocial reference trials in the male participants of Experiment 1. ΔFRN amplitudes were larger for social compared to non-social reference trials in Experiment 1. No effects of reference frame were found in the female sample of Experiment 2. Rather, P2 and ΔFRN effects showed opposing patterns for nonsocial versus social reference frames. However, stronger internal control beliefs were accompanied by larger FRN amplitudes of negative social reference trials in both samples, suggesting generalizable effects independent of sex/gender. Enhanced P2 and ΔFRN amplitudes for social versus nonsocial reference trials suggest enhanced attentional capture and higher saliency of socially framed feedback in male participants only. In both sexes/genders, however, the social reference frame possibly challenges internal control beliefs and by this enhances performance monitoring. Our results demonstrate the complex interplay of trait variables and reference frames during performance monitoring influencing our daily lives-reference frames are omnipresent in education and one’s working environment.     

How Societal Changes Have Influenced German Children’s Gender Representations as Expressed in Human Figure Drawings in 1977 and 2015

Sex Roles - We investigated German first graders’ gender representations in human figure drawings done in 1977 and 2015. We hypothesized that increasing gender-status equality in society as...     

FEMINIST ATTITUDE ACCESSIBILITY AND BEHAVIORAL INTENTIONS

In order to investigate the role of attitude accessibility in reported intentions to engage in feminist behavior, feminist attitudes were or were not activated, and attitude behavior relations in the two conditions were assessed. Overall, the attitude-behavior relationship was strong and significant when the attitude was made accessible via a priming manipulation. In contrast, the attitude-behavior relationship was low and not significant when the attitude was not accessible, even though domain relevant behavioral intentions had been accessed. Other theoretical perspectives, potential d-irectiorss for future research on feminist attitude behavior consistency, and the applied implications are discussed.
