Variations of Bender-Gestalt constriction and depression in adult psychiatric patients.

The present study explored variations of Bender-Gestalt constriction and their relation to depression. 20 Ss showing constriction of drawings on the upper half-page and 20 Ss showing constriction of drawings on the left half-page were compared with regard to MMPI Depression scores. No significant difference was found between these groups. However, when the constricted groups were combined and then compared with 40 Ss who did not show constriction of Bender drawings, the constricted group had significantly higher (p less than .05) MMPI Depression scores. Thus, variations in Bender constriction are not differently related to depression, but presence of constriction is an indicator. However, its rate of occurrence is so infrequent, appearing in only 5% of the records examined, that its clinical usefulness in the detection of depression is quite limited.     

Performance of typical and superior face recognizers on a novel interactive face matching procedure

Unfamiliar simultaneous face matching is error prone. Reducing incorrect identification decisions will positively benefit forensic and security contexts. The absence of view-independent information in static images likely contributes to the difficulty of unfamiliar face matching. We tested whether a novel interactive viewing procedure that provides the user with 3D structural information as they rotate a facial image to different orientations would improve face matching accuracy. We tested the performance of ‘typical’ (Experiment 1) and ‘superior’ (Experiment 2) face recognizers, comparing their performance using high-quality (Experiment 3) and pixelated (Experiment 4) Facebook profile images. In each trial, participants responded whether two images featured the same person with one of these images being either a static face, a video providing orientation information, or an interactive image. Taken together, the results show that fluid orientation information and interactivity prompt shifts in criterion and support matching performance. Because typical and superior face recognizers both benefited from the structural information provided by the novel viewing procedures, our results point to qualitatively similar reliance on pictorial encoding in these groups. This also suggests that interactive viewing tools can be valuable in assisting face matching in high-performing practitioner groups.

Investigating the role of E-contact and self-disclosure on improving Turkish-Kurdish interethnic relations

While recent research has started to pay more attention to the role of contact strategies on promoting intergroup harmony between Turkish and Kurdish communities, the effectiveness of a novel form of indirect contact strategy, E-contact—where participants engage in a cooperative and structured online interaction with an individual from the outgroup—has not yet been tested. Across two studies (N_{Study 1} = 110, N_{Study 2} = 176), we investigated the effects of E-contact among Turks on promoting positive attitudes and behavioral tendencies toward Kurds, testing outgroup trust and intergroup anxiety as mediators and incorporating a distinction between lower and higher self-disclosure conditions. As expected, E-contact led to more positive outgroup attitudes, as well as greater approach tendencies and decreased avoidance tendencies through increased outgroup trust (Studies 1 and 2) and reduced intergroup anxiety (Study 2). Study 2 also found that E-contact produced lower perceived interethnic conflict through increased outgroup trust. While both lower and higher personal disclosure conditions provided similar effects in the two studies, E-contact with heightened self-disclosure was especially effective at promoting more positive outgroup attitudes and reducing avoidance tendencies. Findings highlight potential benefits of using E-contact as a prejudice-reduction strategy in conflict settings.     

Pathways to prejudice and outgroup hostility: Group alignment and intergroup conflict among football fans

How do different forms of group alignment influence our attitudes toward outgroups? To answer this, the current fieldwork study explored how identification and identity fusion differentially impact outgroup anxiety, prejudice, and hostility toward rival football fan supporter groups in Australia. The community participants (N = 100) were members of two active fan groups who had experienced a history of intergroup tensions. The findings from the full path model confirmed that the predictor group alignment variables of identification and fusion were correlated, and the two outcome variables of outgroup prejudice and hostility were correlated, as predicted. The findings also revealed that fusion with one's club predicted outgroup hostility, but not prejudice, whereas identification with one's club predicted outgroup prejudice, but not hostility. Additionally, outgroup anxiety was found to significantly mediate the relationship between ingroup identification and outgroup prejudice, whereas a similar relationship was not found for fusion. These findings highlight the differential impact of group alignment (i.e., identification and identity fusion) on social constructs of outgroup anxiety, prejudice, and hostility. Empirically, this is the first study to demonstrate the workings of these distinct group alignment pathways in an applied setting involving hard-core football fans. We discuss the broader implications of these findings for a fuller understanding of the drivers of intergroup tensions and conflict.     

Localized intracaudate dopamine D2 receptor activation during the post-training period improves memory for visual or olfactory conditioned emotional responses in rats.

Rats with cannulas aimed at the posteroventral (PV) or ventrolateral (VL) areas of the caudate nucleus were trained on a conditioned emotional response (CER) task. Post-training microinjections of the indirect catecholamine agonist, d-amphetamine (5 micrograms), or of the dopamine D2 receptor agonist, LY171555 (1 microgram), into the PV area improved retention of a CER with a visual CS, but had no effect on a CER with an olfactory CS. Post-training injections of the same two drugs into the VL area improved retention of a CER with an olfactory CS, but had no effect on a CER with a visual CS. Post-training injections of the dopamine D1 receptor agonist, SKF38393 (0.5, 1.0, 2.0 micrograms), into either site had no effects on either CER. These findings suggest that different areas of the caudate nucleus mediate acquisition of CERs with different CSs, possibly implicating the topographically organized corticostriatal innervation in the acquisition of certain types of memories in the caudate nucleus. The findings also suggest that dopamine D2 receptors in the caudate nucleus are involved in the acquisition of these CERs.

Extinction revisited: similarities between extinction and reductions in US intensity in classical conditioning of the rabbit's nictitating membrane response

The mechanisms of extinction were examined by reducing the intensity of the unconditioned stimulus (US) after acquisition training to determine whether such reductions lie on a continuum with CS-alone extinction. The experiments revealed that reductions in US intensity yielded extinction-like effects. Specifically, there were proportional reductions in the daily mean level of responding across sessions. There were also persistent within-session declines and between-session increases of responding analogous to spontaneous recovery. Surprisingly, even when US intensity was held constant, within-session declines and between-session increases were apparent. The results are discussed with respect to possible contributions from unlearning, new learning, generalization decrement, and nonassociative loss, especially CS-specific attentional changes and CR-specific reactive inhibition.
