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

Ethnicity matters for undergraduate majors in challenges, experiences, and perceptions of psychology
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

Many human activities involve a risk of physical harm. However, not much is known about the specific brain regions involved
in decision making regarding these risks. To explore the neural correlates of risk perception for physical harms, 19 participants
took part in an event-related fMRI study while rating risky activities. The scenarios varied in level of potential harm (e.g.,
paralysis vs. stubbed toe), likelihood of injury (e.g., 1 chance in 100 vs. 1 chance in 1,000), and format (frequency vs.
probability). Networks of brain regions were responsive to different aspects of risk information. Cortical language- processing
areas, the middle temporal gyrus, and a region around the bed nucleus of stria terminalis responded more strongly to high-
harm conditions. Prefrontal areas, along with subcortical ventral striatum, responded preferentially to high- likelihood conditions.
Participants rated identical risks to be greater when information was presented in frequency format rather than probability
format. These findings indicate that risk assessments for physical harm engage a broad network of brain regions that are sensitive
to the severity of harm, the likelihood of risk, and the framing of risk information. 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

Social anxiety as a basis for friendship selection and socialization in adolescents' social networks
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

In this study, we sought to understand why people engage in these two forms of voluntary and discretionary behaviours. Expanding upon key resource theories to include individual abilities, we examined the idea of incongruence between resources and behaviours (i.e., resources that have been traditionally framed with a positive tone lead to negative behaviours and resources that have been traditionally framed with a negative tone lead to positive behaviours). Data from 234 employees revealed that impulsivity positively influenced organizational citizenship behaviours, and that emotional intelligence (EI) significantly contributed to deviant workplace behaviours. Post hoc analysis revealed that the ability to perceive emotions was the most influential branch of EI in predicting deviant behaviours. We thus found a non‐compatible view of the individual resources–behaviour relationship, such that ‘positive’ personal resources lead to negative behaviours and ‘negative’ personal resources lead to positive behaviours. Implications for research and practice are discussed. 相似文献

Background. Children may experience two very different forms of reading problem: decoding difficulties (dyslexia) and reading comprehension difficulties. Decoding difficulties appear to be caused by problems with phonological (speech sound) processing. Reading comprehension difficulties in contrast appear to be caused by problems with ‘higher level’ language difficulties including problems with semantics (including deficient knowledge of word meanings) and grammar (knowledge of morphology and syntax). Aims. We review evidence concerning the nature, causes of, and treatments for children's reading difficulties. We argue that any well‐founded educational intervention must be based on a sound theory of the causes of a particular form of learning difficulty, which in turn must be based on an understanding of how a given skill is learned by typically developing children. Such theoretically motivated interventions should in turn be evaluated in randomized controlled trials (RCTs) to establish whether they are effective, and for whom. Results. There is now considerable evidence showing that phonologically based interventions are effective in ameliorating children's word level decoding difficulties, and a smaller evidence base showing that reading and oral language (OL) comprehension difficulties can be ameliorated by suitable interventions to boost vocabulary and broader OL skills. Conclusions. The process of developing theories about the origins of children's educational difficulties and evaluating theoretically motivated treatments in RCTs, produces a ‘virtuous circle’ whereby theory informs practice, and the evaluation of effective interventions in turn feeds back to inform and refine theories about the nature and causes of children's reading and language difficulties. 相似文献

The present article investigates spatial- and social-cognitive processes in toddlers' mapping of concepts to real-world events. In 2 studies we explore how event segmentation might lay the groundwork for extracting actions from the event stream and conceptually mapping novel verbs to these actions. In Study 1, toddlers demonstrated the ability to segment a novel multiaction event by selecting a single action for behavioral reenactment when prompted. In Study 2, a single action embedded in the event sequence was specified as the referent for a novel verb through cues to support intentional inference. As in Study 1, toddlers spontaneously segmented the sequence. In addition, they mapped a novel label to the embedded action specified by the novel label and intentional cues. These data are consistent with current thinking that suggests a convergence of spatial and social cognition in verb learning. In the present research, toddlers built upon event segmentation skills and used intentional inference when mapping verbs to actions embedded in the motion stream. 相似文献
