Participants were exposed to a crime story embedded in a newscast in a 3 (Officer Race—Black, White, or Race Unidentified) × 3 (Perpetrator Race—Black, White, or Race Unidentified) × 2 (Prior News Viewing—Heavy, Light) factorial design. Afterward, participants were asked the likelihood that the depicted officer and perpetrator were either White or Black. In addition, participants were asked how positively they viewed the officer who was featured in the story. Results revealed that race unidentified perpetrators were rated as having a high likelihood of being Black. In addition, heavy news viewers were more likely than light news viewers to express a high likelihood that the unidentified officer was White. Finally, heavy news viewers were more likely than light news viewers to have positive perceptions of unidentified officers, but not of Black officers featured in a newscast. The theoretical implications of these findings are discussed in light of cultivation and chronic activation. 相似文献

An influential neurocomputational theory of the biological mechanisms of decision making, the “basal ganglia go/no-go model,” holds that individual variability in decision making is determined by differences in the makeup of a striatal system for approach and avoidance learning. The model has been tested empirically with the probabilistic selection task (PST), which determines whether individuals learn better from positive or negative feedback. In accordance with the model, in the present study we examined whether an individual’s ability to learn from positive and negative reinforcement can be predicted by genetic factors related to the midbrain dopamine system. We also asked whether psychiatric and personality factors related to substance dependence and dopamine affect PST performance. Although we found characteristics that predicted individual differences in approach versus avoidance learning, these observations were qualified by additional findings that appear inconsistent with the predictions of the go/no-go model. These results highlight a need for future research to validate the PST as a measure of basal ganglia reward learning. 相似文献

Completing a representational momentum (RM) task, participants viewed one of three camera motions through a scene and indicated whether test probes were in the same position as they were in the final view of the animation. All camera motions led to RM anticipations in the direction of motion, with larger distortions resulting from rotations than a compound motion of a rotation and a translation. A surprise test of spatial layout, using an aerial map, revealed that the correct map was identified only following aerial views during the RM task. When the RM task displayed field views, including repeated views of multiple object groups, participants were unable to identify the overall spatial layout of the scene. These results suggest that the object–location binding thought to support certain change detection and visual search tasks might be viewpoint dependent. 相似文献

The physical disabilities associated with scleroderma are well known but the psychological impact of the condition has received less attention. Few studies have examined appearance related issues, most notably of the face. The aim of this study is to evaluate the psychological impact of facial, aesthetic and functional changes in scleroderma. One hundred seventy-one patients with a clinical diagnosis of scleroderma were recruited into the study. Digital photographs were objectively graded into groups based on severity of disfigurement as judged by an observer. Facial movement was recorded using a modified House-Brackmann Grading Scale. Psychological evaluation comprised the Derriford Appearance Scale short-form (DAS), the Noticeability and Worry score and the Hospital Anxiety and Depression Scale (HADS). Severity of disfigurement predicted decreased mouth opening, the extent to which participants judged their appearance as noticeable to others, and the level of appearance-related concern as measured by the DAS24. There was an inverse relationship with age. Facial changes were ranked as the most worrying aspect of the condition. This study shows facial disfigurement impacts on patient with scleroderma independent of functional changes related to systemic disease. The major difficulty is with the perceived noticeably of the condition to other people and the resulting self-consciousness in social encounters. 相似文献

People commonly believe that they communicate better with close friends than with strangers. We propose, however, that closeness can lead people to overestimate how well they communicate, a phenomenon we term the closeness-communication bias. In one experiment, participants who followed direction of a friend were more likely to make egocentric errors—look at and reach for an object only they could see—than were those who followed direction of a stranger. In two additional experiments, participants who attempted to convey particular meanings with ambiguous phrases overestimated their success more when communicating with a friend or spouse than with strangers. We argue that people engage in active monitoring of strangers’ divergent perspectives because they know they must, but that they “let down their guard” and rely more on their own perspective when they communicate with a friend. 相似文献

Aggression in adolescents is harmful and emotionally devastating to youth and surrounding communities. This article integrates martial arts and therapeutic principles into a culturally sensitive model that cultivates change in the aggressive behaviors of disenfranchised adolescents. The art form of Capoeira is proposed for promoting positive behavioral change. La agresión en los adolescentes es dañina y emocionalmente devastadora para los jóvenes y sus comunidades. Este artículo integra artes marciales y principios terapéuticos en un modelo culturalmente sensible que cultiva el cambio de los comportamientos agresivos de los adolescentes marginalizados. Se propone el arte de la Capoeira para promover un cambio positivo en el comportamiento. 相似文献

Inhibition is a core executive function reliant on the frontal lobes that shows protracted maturation through to adulthood. We investigated the spatiotemporal characteristics of response inhibition during a visual go/no-go task in 14 teenagers and 14 adults using magnetoencephalography (MEG) and a contrast between two no-go experimental conditions designed to eliminate a common confound in earlier studies comparing go with no-go trials. Source analyses were performed using an event-related beamformer algorithm with co-registered individual structural MRIs. Performance was controlled to be similar across subjects. Analyses of MEG data revealed bilateral prefrontal activity in the inhibitory condition for both age groups, but with different spatiotemporal patterns: around 300ms after stimulus onset in middle frontal gyri in teenagers vs. around 260ms in inferior frontal gyri in adults. Moreover, the inhibition of a prepotent motor response showed a stronger recruitment of the left hemisphere in teenagers than in adults and of the right hemisphere in adults than in teenagers. These findings provide high-resolution temporal and spatial information regarding response inhibition in adolescents compared to adults, independent of motor components and performance differences. 相似文献
