Neural substrates for episodic encoding and recognition of unfamiliar faces

Functional MRI was used to investigate brain activation in healthy volunteers during encoding of unfamiliar faces as well as during correct recognition of newly learned faces (CR) compared to correct identification of distractor faces (CF), missed alarms (not recognizing previously presented faces, MA), and false alarms (incorrectly recognizing newly presented faces, FA). Encoding was associated with frontal, occipital/fusiform, thalamic, and cerebellar activation. CR produced activation in frontal and cerebellar regions, whereas CF activated frontal and occipitotemporal regions as well as the thalamus. In contrast, MA was associated with frontal and thalamic activation, and FA with frontal activation. The CR minus CF comparison showed left lateral prefrontal and parietal activation, while no suprathreshold positive signal changes were detected when subtracting the other conditions (CR minus MA, CR minus FA, and vice versa). These results support the view that the successful episodic retrieval of newly learned faces is based on a dorsal visual stream mechanism.     

Trauma and Religiousness

Victims of traumatic events who experience re-traumatization often develop a highly ambivalent relationship to God and all religiosity as extremely conflictual. On the one hand, they may choose to blame God for not having protected them, for having left them to feel so alone, for having been indifferent to them or they may even turn their wrath upon God, as the source of cruelty. Often though, the traumas experienced by individuals prompt them to turn to God and religion in search of help. This gives reason for the need of new and up-to-date research that can help elucidate why some people choose to seek help in religion and others turn away from it.     

‘Who's the Thief?’ The Influence of Knowledge and Experience on Early Detection of Criminal Intentions

Our study investigates if people are able to recognize thieves based on their nonverbal behavior prior to committing the crime. We implemented authentic closed‐circuit television footage from thefts committed at an international airport into a computer‐based test. Five groups of participants (students, police recruits, inexperienced police officers, experienced police officers, and criminal investigators) were studied. The results show that criminals display nonverbal behavior that can be used by observers for early recognition of criminal intentions. In addition, early recognition seems to benefit from knowledge about the criminals' modi operandi (criminal investigators performed best), which renders early recognition teachable and trainable. Further, all participants seem to be biased towards innocence, but this bias was less pronounced in police officers than in students. These findings are discussed in relation to the well‐documented truth‐bias and investigator‐bias in lie detection research as well as taking our measurement method into account.Copyright © 2015 John Wiley & Sons, Ltd.     

Uncertainty is associated with increased selective attention and sustained stimulus processing

Uncertainty about future threat has been found to be associated with an overestimation of threat probability and is hypothesized to elicit additional allocation of attention. We used event-related potentials to examine uncertainty-related dynamics in attentional allocation, exploiting brain potentials’ high temporal resolution and sensitivity to attention. Thirty participants performed a picture-viewing task in which cues indicated the subsequent picture valence. A certain-neutral and a certain-aversive cue accurately predicted subsequent picture valence, whereas an uncertain cue did not. Participants overestimated the effective frequency of aversive pictures following the uncertain cue, both during and after the task, signifying expectancy and covariation biases, and they tended to express lower subjective valences for aversive pictures presented after the uncertain cue. Pictures elicited increased P2 and LPP amplitudes when their valence could not be predicted from the cue. For the LPP, this effect was more pronounced in response to neutral pictures. Uncertainty appears to enhance the engagement of early phasic and sustained attention for uncertainly cued targets. Thus, defensive motivation related to uncertainty about future threat elicits specific attentional dynamics implicating prioritization at various processing stages, especially for nonthreatening stimuli that tend to violate expectations.     

Time‐of‐day variation of visuo‐spatial attention

Time‐of‐day variation of visuo‐spatial attention in relation to body temperature and subjective arousal was assessed. At five different times of day, alertness, covert, and overt orienting of attention were assessed in fifteen healthy subjects. Based on previous studies reporting a tight coupling of alerting and orienting the present study investigates potential attentional asymmetries induced by diurnal variations of arousal. Both covert and overt orienting of attention improved in the course of the day. However, no asymmetries between left and right visual hemifields could be detected. Covert orienting additionally covaried with body temperature, indicating a quite close relation between the attentional arousal and orienting system. Conversely, overt orienting only improved due to repeated testing but did not correlate with body temperature suggesting a partial independence of both modes of attentional orienting. It can be assumed that due to limited diurnal variations of arousal in the participants and practice effects caused by repeated testing, no attentional asymmetries could be provoked.     

Parents’ Judgments about the Desirability of Toys for Their Children: Associations with Gender Role Attitudes,Gender-typing of Toys,and Demographics

Parental toy selection and responses to toy play are important factors in children’s gender socialization. Reinforcing play with same-gender-typed toys guides children’s activities and limits their action repertoires in accordance with gender stereotypes. A survey of 324 Austrian parents of three- to six-year-old children was conducted to investigate parents’ judgments about the desirability of different types of toys for their children and how these judgements relate to parents’ gender-typing of toys, gender role attitudes, and demographics (age, education, gender). Results show that parents rated same-gender-typed and gender-neutral toys as more desirable for their children than cross-gender-typed toys. The traditionalism of parents’ gender role attitudes was not associated with their desirability judgments of same-gender-typed toys, but was negatively related to their desirability judgments of cross-gender-typed toys. This indicates that egalitarian parents permit a greater range of interests and behaviors in their children than traditional parents do. Younger parents, parents with lower educational levels, and fathers reported more traditional gender role attitudes than did older parents, parents with higher educational levels, and mothers. However, no differences based on age, educational level or gender were found in parents’ judgments of toy desirability. The present study demonstrates that parents’ judgments about the desirability of toys for their children do not accurately reflect their gender role attitudes. This finding highlights the importance of simultaneously investigating different aspects of parents’ gender-related attitudes in order to gain a better understanding of parental transmission of gender stereotypes.

Long-term improvement in coping skills following multimodal treatment in war veterans with chronic PTSD

Due to the long-lasting and resistant symptoms characteristic of chronic combat posttraumatic stress disorder (PTSD), its treatment is complex and often requires a tailored therapeutic approach incorporating both psychotherapy and pharmacotherapy. A multimodal approach of psychoeducative, sociotherapeutic, and dynamically oriented trauma-focused groups is described. We assessed the short- and long-term effectiveness of this therapeutic program by monitoring its impact on PTSD symptoms, depression, neurotic symptoms, coping skills, and quality of life for three years. The findings revealed short-term reduction in the symptoms of PTSD and depression, while the long-term results were manifested as the increased use of all coping mechanisms and a greater level of obsession.     

Justice sensitivity and forgiveness in close interpersonal relationships: the mediating role of mistrustful, legitimizing, and pro-relationship cognitions

The purpose of the present investigation was to explore and better understand the relationship between justice sensitivity from a victim's perspective (JS‐victim) and interpersonal forgiveness. In particular, we aimed to identify the cognitive mechanisms mediating this relationship and test the moderating influence of post‐transgression perpetrator behavior. We used data from a questionnaire study employing a Swiss community sample (N = 450) and 2 scenario‐based studies employing German online samples, in the context of romantic (N = 242) and friendship relationships (N = 974). We consistently found JS‐victim to be negatively related to dispositional (Study 1) and situational forgiveness (Studies 2 and 3). Study 2 demonstrated the relationship between JS‐victim and reduced forgiveness to be partly mediated by mistrustful interpretations of the partner's post‐transgression behavior. In Study 3, cognitions legitimizing one's own antisocial reactions and a lack of pro‐relationship cognitions were identified as further mediators. These variables mediated the negative effect of JS‐victim on forgiveness largely independent of whether the friend perpetrator displayed reconciliatory behavior or not. Findings suggest that the cognitive mechanisms mediating victim‐sensitive individuals' unforgiveness could barely be neutralized. Future research should investigate their malleability in light of qualitatively different perpetrator behaviors as well as their broader relational implications.
