Self report and observational data on racial socialization practices in a sample of 218 African American parents of young children were used to determine whether or not parents could be characterized in terms of their pattern of racial socialization practices. Parents fell into four groups: silence about race, emphasis on cultural socialization, emphasis on cultural socialization and coping strategies, or a balanced approach. Silence about race was more common among parents of boys, whereas an emphasis on cultural socialization was more common among parents of girls. Silence about race was less common in neighborhoods with high levels of negative social climate, and a combination of cultural socialization with coping strategies for discrimination was more common in neighborhoods with high neighborhood potential for community involvement with children. The coping emphasis/cultural socialization approach was associated with significantly lower child problem behavior, although some gender differences were evident. A cultural socialization emphasis was associated with higher cognitive scores among girls, and a combination of cultural socialization, coping with discrimination, and promotion of mistrust was associated with higher cognitive scores among boys. Implications of this profile approach for the study of racial socialization practices in ethnic minority families are discussed.  相似文献

Huntington disease (HD) is caused by an expansion of CAG repeat in the Huntingtin gene. Patients demonstrate a triad of motor, cognitive and psychiatric symptoms. A transgenic rat model (tgHD rats) carrying 51 CAG repeats demonstrate progressive striatal degeneration and polyglutamine aggregates in limbic structures. In this model, emotional function has only been investigated through anxiety studies. Our aim was to extend knowledge on emotional and motivational function in symptomatic tgHD rats. We subjected tgHD and wild-type rats to behavioral protocols testing motor, emotional, and motivational abilities. From 11 to 15 months of age, animals were tested in emotional perception of sucrose using taste reactivity, acquisition, extinction, and re-acquisition of discriminative Pavlovian fear conditioning as well as reactivity to changes in reinforcement values in a runway Pavlovian approach task. Motor tests detected the symptomatic status of tgHD animals from 11 months of age. In comparison to wild types, transgenic animals exhibited emotional blunting of hedonic perception for intermediate sucrose concentration. Moreover, we found emotional alterations with better learning and re-acquisition of discriminative fear conditioning due to a higher level of conditioned fear to aversive stimuli, and hyper-reactivity to a negative hedonic shift in reinforcement value interpreted in term of greater frustration. Neuropathological assessment in the same animals showed a selective shrinkage of the central nucleus of the amygdala. Our results showing emotional blunting and hypersensitivity to negative emotional situations in symptomatic tgHD animals extend the face validity of this model regarding neuropsychiatric symptoms as seen in manifest HD patients, and suggest that some of these symptoms may be related to amygdala dysfunction.  相似文献

In this investigation of a national sample of undergraduate psychology majors, we directly compare the experiences and perceptions of students of color with those of European Americans. Our aim was to identify factors that might contribute to our discipline's educational pipeline, in which the relative lack of ethnic diversity is a recognized problem. We found that students of color and European American majors are similar in a number of ways but also different in others. Students of color are challenged by less encouragement from and interaction with faculty, perceive a lack of respect, and wish to see more attention to diversity in curriculum, research, faculty, and textbooks. It is not surprising that students of color were significantly less satisfied than European Americans with their studies in psychology.  相似文献

Prior studies suggest a positive association between life satisfaction and wisdom. In a sample with 123 European American community-dwelling adults, the results suggest that wisdom and life satisfaction are positively intertwined, and that openness value is an important factor for life satisfaction, a self-transcendence orientation, and wisdom.  相似文献

A multitask battery tapping nonverbal memory and language skills was used to assess 60 children at 18, 24, and 30 months of age. Analyses focused on the degree to which language, working memory, and deliberate memory skills were linked concurrently to children’s Elicited Imitation task performance and whether the patterns of association varied across the different ages. Language ability emerged as a predictor of immediate Elicited Imitation performance by 24 months of age and predicted delayed performance at each age. In addition to the contributions of language, children’s abilities to search for and retrieve toys in the deliberate memory task were associated with their immediate Elicited Imitation performance at each age. In addition to language, working memory was positively associated with aspects of both immediate and delayed performance at all ages. The extent to which it was possible to replicate and extend previous cross-sectional work in this longitudinal study is discussed.  相似文献

The relationships between personality traits and performance are often assumed to be linear. This assumption has been challenged conceptually and empirically, but results to date have been inconclusive. In the current study, we took a theory-driven approach in systematically addressing this issue. Results based on two different samples generally supported our expectations of the curvilinear relationships between personality traits, including Conscientiousness and Emotional Stability, and job performance dimensions, including task performance, organizational citizenship behavior, and counterproductive work behaviors. We also hypothesized and found that job complexity moderated the curvilinear personality–performance relationships such that the inflection points after which the relationships disappear were lower for low-complexity jobs than they were for high-complexity jobs. This finding suggests that high levels of the two personality traits examined are more beneficial for performance in high- than low-complexity jobs. We conclude by discussing the implications of these findings for the use of personality in personnel selection.  相似文献

Socially anxious children and adolescents have previously been found to have friends with similarly socially anxious, withdrawn behavioral characteristics. How peers might socialize social anxiety over time has, however, not been thoroughly investigated. We examined this in a sample of 834 youths (339 girls and 495 boys; M=14.29), followed for 3 years. We used the social network analysis software SIENA to analyze the data. The results showed that youths who were socially anxious were less popular and chose fewer friends in the network. They also tended to choose friends who were socially anxious, and over time they influenced each other into becoming more socially anxious--over and above other effects. Finally, girls' social anxiety was more influenced than boys' by their friends' social anxiety levels. The results showed the significance of looking at socially anxious youths' friendships over time and embedded in social networks.  相似文献

Participant sex and a theorized correlate of biological sex, relational interdependence, were tested as relative predictors of the extent to which daters 1) missed and 2) used emotional support to cope when geographically separated from their dating partners. One hundred twenty-four daters completed multiple measures of missing and coping during their colleges' winter breaks. Results from regression analyses indicated that levels of missing and seeking emotional support differed as a function of biological sex. Further, relational interdependence was reliably associated with missing and seeking emotional support in theoretically consistent ways. Mediation analyses highlighted the importance of considering relational interdependence or other individual differences that covary with biological sex when studying close relationship phenomena.  相似文献

Recent research has argued that several well-known judgment biases may be due to biases in the available information sample rather than to biased information processing. Most of these sample-based explanations assume that decision makers are "naive": They are not aware of the biases in the available information sample and do not correct for them. Here, we show that this "naivety" assumption is not necessary. Systematically biased judgments can emerge even when decision makers process available information perfectly and are also aware of how the information sample has been generated. Specifically, we develop a rational analysis of Denrell's (2005) experience sampling model, and we prove that when information search is interested rather than disinterested, even rational information sampling and processing can give rise to systematic patterns of errors in judgments. Our results illustrate that a tendency to favor alternatives for which outcome information is more accessible can be consistent with rational behavior. The model offers a rational explanation for behaviors that had previously been attributed to cognitive and motivational biases, such as the in-group bias or the tendency to prefer popular alternatives.  相似文献
