Abstract-Numerous studies have documented the potential for victim-blaming attributions to justify the status quo. Recent work suggests that complementary, victim-enhancing stereotypes may also increase support for existing social arrangements. We seek to reconcile these seemingly contradictory findings by proposing that victim derogation and victim enhancement are alternate routes to system justification, with the preferred route depending on the perception of a causal link between trait and outcome. Derogating "losers" (and lionizing "winners") on traits (e.g., intelligence) that are causally related to outcomes (e.g., wealth vs. poverty) serves to increase system justification, as does compensating "losers" (and downgrading "winners") on traits (e.g., physical attractiveness) that are causally unrelated to those outcomes. We provide converging evidence using system-threat and stereotype-activation paradigms. 相似文献

In a laboratory setting, 135 undergraduate students (69 male, 66 female; approximately 98% white) completed a mock class scheduling task led by a female confederate who was chosen either preferentially or by merit. Results indicated that (1) subordinate evaluations of female leader performance were not affected by preferential selection, but were significantly related to degree of non-traditional views held toward female managers; (2) commitment to the goal assigned by the female leader was not lessened by preferential selection, but also was significantly related to degree of non-traditional views toward female managers; and (3) subordinate performance on the scheduling task was significantly related to commitment to the leader-assigned goal. 相似文献

Perceived family environments of depressed and anxious children: Child's and maternal figure's perspectives 总被引:6,自引:0,他引:6
Kevin D. Stark Laura Lynn Humphrey Kim Crook Kay Lewis 《Journal of abnormal child psychology》1990,18(5):527-547
This study examined perceived environment among families with a depressed, depressed and anxious, anxious, or normal child from the 4th to 7th grades. Fifty-one such children were classified according to criteria from the K- SADS and a set of self-ratings of depression and anxiety. Results showed that children in all three diagnostic groups, and to a lesser extent their mothers, experienced their families as more distressed on a host of dimensions relative to controls. In addition, significant differences were found between families with a depressed and anxious child and those with an anxious child. Discriminant function analyses revealed that 68.63 % of the youngsters could be classified correctly into depressed and anxious groups on the basis of their family ratings alone. 相似文献

Engagement in peer play is an important factor in young children's adjustment as they make the transition to school. We evaluated individual differences in peer play within a sample of 58 children aged 4–5 years. Among boys, but not among girls, emotion understanding and verbal ability independently served as positive predictors of interactive peer play and negative predictors of disconnected play. Among girls, but not among boys, interactive peer play and socio‐moral reasoning about peer conflict situations independently predicted sociometric most‐like nominations. The results provide a foundation for further research on divergence in the early peer play of girls and boys. 相似文献

The deterioration of performance over time is characteristic for sustained attention tasks. This so-called “performance decrement” is measured by the increase of reaction time (RT) over time. Some behavioural and neurobiological mechanisms of this phenomenon are not yet fully understood. Behaviourally, we examined the increase of RT over time and the inter-individual differences of this performance decrement. On the neurophysiological level, we investigated the task-relevant brain areas where neural activity was modulated by RT and searched for brain areas involved in good performance (i.e. participants with no or moderate performance decrement) as compared to poor performance (i.e. participants with a steep performance decrement). For this purpose, 20 healthy, young subjects performed a carefully designed task for simple sustained attention, namely a low-demanding version of the Rapid Visual Information Processing task. We employed a rapid event-related functional magnetic resonance imaging (fMRI) design. The behavioural results showed a significant increase of RT over time in the whole group, and also revealed that some participants were not as prone to the performance decrement as others. The latter was statistically significant comparing good versus poor performers. Moreover, high BOLD-responses were linked to longer RTs in a task-relevant bilateral fronto-cingulate-insular-parietal network. Among these regions, good performance was associated with significantly higher RT-BOLD correlations in the pre-supplementary motor area (pre-SMA). We concluded that the task-relevant bilateral fronto-cingulate-insular-parietal network was a cognitive control network responsible for goal-directed attention. The pre-SMA in particular might be associated with the performance decrement insofar that good performers could sustain activity in this brain region in order to monitor performance declines and adjust behavioural output. 相似文献

Endorsing meritocracy can make low-status group members more accepting of inequality. This study examined whether rejecting meritocracy is related to increased ethnic identification among Latino immigrants, and whether identity in turn is related to increased support for collective action. We hypothesize that these relationships depend upon immigrant generation. A survey was conducted with 184 first- and second-generation Latino immigrants in New York City. Second-generation Latinos endorsed meritocracy less than those in the first generation, at least in part because they perceived that other Americans viewed their group in a less positive light (i.e., lower public regard). Further, meritocracy was negatively linked to ethnic identity and, through it, support for collective action among the second generation. Among the first generation, meritocracy was not related to ethnic identity and was positively related to support for collective action. We discuss the implications of growing up near the bottom of the U.S. social hierarchy for ethnic identity and collective action. 相似文献
