Adults show better memory for ambiguous faces of their own race than for ambiguous faces of another race, even when the faces are identical and differentiated only by extraneous cues to racial category. We investigated whether similar context effects operate early in development. Young children raised in predominantly White environments were presented with computer-generated White-Black morphed faces, each paired with either the White or the Black face that contributed to its construction, and were told that the two faces in each pair were siblings. The children's subsequent recognition memory was more accurate for faces that had been paired with White siblings than for faces that had been paired with Black siblings. The same effect did not obtain when the ambiguous faces were paired with White or Black faces that did not contribute to their construction and did not look like siblings. These findings suggest that face memory in children is not driven exclusively by visual information present in faces and instead depends on an interplay of categorical and perceptual information about race and relationships.  相似文献

Cognitive costs of exposure to racial prejudice   总被引:1,自引:0,他引:1  
This study examined how encountering racial prejudice affects cognitive functioning. We assessed performance on the Stroop task after subjects reviewed job files that suggested an evaluator had made nonprejudiced, ambiguously prejudiced, or blatantly prejudiced hiring recommendations. The cognitive impact of exposure to ambiguous versus blatant cues to prejudice depended on subjects' racial group. Black subjects experienced the greatest impairment when they saw ambiguous evidence of prejudice, whereas White subjects experienced the greatest impairment when they saw blatant evidence of prejudice. Given the often ambiguous nature of contemporary expressions of prejudice, these results have important implications for the performance of ethnic minorities across many domains.  相似文献

Randomization procedures are performed in order to maximize the internal validity of treatment outcome studies. Objections have been made that this practice undermines the external validity of these studies because it ignores patients' treatment preferences, thereby precluding the self-selection of treatment that can occur in the community. This study used data from a multisite, double-blind, randomized, placebo-controlled trial comparing antidepressant medication to cognitive therapy for moderately to severely depressed outpatients. It compared the treatment outcomes of patients who, via randomization, received their preferred treatment versus those who did not. Although the majority of patients stated a preference for one treatment over the other, there was no significant difference in the magnitude of reduction in symptoms of depression between those who received their treatment of choice versus those who did not. These results do not provide support for the claim that the external validity of randomized controlled trials suffers from this aspect of the randomization procedure.  相似文献

In the negotiation literature, relatively little attention has been paid to the impact of negotiator goals and expectancy disconfirmations on negotiator behaviors and affective outcomes. We found that negotiators with larger negative expectancy disconfirmations were less satisfied; set lower targets for a subsequent negotiation; and were more likely to settle with the other party in the second negotiation, rather than requiring third-party imposition of a settlement. Those negotiators who settled had more positive feelings and perceptions about the negotiation and set higher targets for a third negotiation. Further, negotiators who experienced repeated high levels of negative expectancy disconfirmation also experienced the greatest decrements in their feelings and perceptions across negotiation episodes. Implications of study findings for future research are discussed.  相似文献

In this longitudinal study, the authors tested a developmental hypothesis derived from attachment theory and recent empirical findings. Target participants were 78 individuals who have been studied intensively from infancy into their mid-20s. When targets were 20-23 years old, the authors tested the way in which interpersonal experiences at 3 pivotal points in each target's earlier social development--infancy/early childhood, early elementary school, and adolescence--predicted the pattern of positive versus negative emotions experienced with his or her romantic partner. A double-mediation model revealed that targets classified as securely attached at 12 months old were rated as more socially competent during early elementary school by their teachers. Targets' social competence, in turn, forecasted their having more secure relationships with close friends at age 16, which in turn predicted more positive daily emotional experiences in their adult romantic relationships (both self- and partner-reported) and less negative affect in conflict resolution and collaborative tasks with their romantic partners (rated by observers). These results are discussed in terms of attachment theory and how antecedent life experiences may indirectly shape events in current relationships.  相似文献

This study is composed of 37 American adolescents, ages 15 to 17 years of age, all from the United States. The principal author was the sole examiner. Inclusion criteria are described. Interrater reliability statistics at the response level are presented along with scores for the Rorschach Comprehensive System (CS; Exner, 2003). The results revealed differences from the published norms on variables that reflect poor form quality, fewer popular responses, more attention to detail, more poor human relationship responses, and a more simplistic, affective-free approach to the environment, among others.  相似文献

In the present study, potential MMPI-2 predictors of psychotherapy outcome were examined in a community clinical sample of 51 patients seeking treatment at a university training clinic. Results indicated that particular MMPI-2 scales (L, F, Pd, Pa, Sc, Trt) were the most predictive of initial levels of patient distress, whereas three other clinical scales (Hs, D, Hy) were significantly associated with actual symptom reduction over time. The clinical implications of these data include the use of the MMPI-2 in clinical practice as a means to frame the provision of direct feedback to patients regarding the likelihood of treatment response, which in turn, might actually have therapeutic benefits. The limitations of the study are reviewed and suggestions for future research are offered, including the potential use of widely known and utilized instruments in helping to predict response to psychotherapy.  相似文献

We determined whether effects of neighborhood socioeconomic disadvantage on trajectories of aggression were moderated or mediated by neighborhood social organization and examined sex differences in neighborhood effects for rural adolescents. We used five waves of survey data collected over 2.5 years linked with neighborhood data from interviews with parents and the US Census. The sample (N = 5,118) was 50.1% female, 52.0% white and 38.3% African–American; average age at baseline was 13.1 years. Multilevel growth curve models for both girls and boys showed no significant interactions between neighborhood socioeconomic disadvantage and indicators of social organization. Neither sample showed evidence of mediated effects. In main effects models, neighborhood disadvantage was associated with the average aggression trajectory for girls. For boys, the effects of neighborhood socioeconomic disadvantage and social disorganization appeared to be confounded with each other. Neighborhood disadvantage is detrimental for rural girls regardless of the level of social organization.  相似文献

The working memory (WM) construct is conceptualized similarly across domains of psychology, yet the methods used to measure WM function vary widely. The present study examined the relationship between WM measures used in the laboratory and those used in applied settings. A large sample of undergraduates completed three laboratory-based WM measures (operation span, listening span, and n-back), as well as the WM subtests from the Wechsler Adult Intelligence Scale-III and the Wechsler Memory Scale-III. Performance on all of the WM subtests of the clinical batteries shared positive correlations with the lab measures; however, the Arithmetic and Spatial Span subtests shared lower correlations than the other WM tests. Factor analyses revealed that a factor comprising scores from the three lab WM measures and the clinical subtest, Letter-Number Sequencing (LNS), provided the best measurement of WM. Additionally, a latent variable approach was taken using fluid intelligence as a criterion construct to further discriminate between the WM tests. The results revealed that the lab measures, along with the LNS task, were the best predictors of fluid abilities.  相似文献

This study of infant declarative memory concurrently examined brain-electrical activity and deferred imitation performance in 10-month-old infants. Continuous electroencephalogram (EEG) measures were collected throughout the activity-matched baseline, encoding (modeling) and retrieval (delayed test) phases of a within-subjects deferred imitation task. Infants were divided into two memory performance groups based on the exhibition of ordered-recall after a 24-h delay. Whereas no group differences were found in EEG collected during encoding, performance-group differences in EEG were present during retrieval. Infants who successfully displayed ordered-recall showed a pattern of increasing EEG from baseline to task at anterior temporal scalp locations, whereas infants showing no ordered-recall displayed no changes in EEG from baseline to task. These findings are discussed with respect to the biobehavioral developments underlying declarative memory abilities.  相似文献
