Bilingualism: consequences for mind and brain 总被引:1,自引:0,他引:1
Building on earlier evidence showing a beneficial effect of bilingualism on children's cognitive development, we review recent studies using both behavioral and neuroimaging methods to examine the effects of bilingualism on cognition in adulthood and explore possible mechanisms for these effects. This research shows that bilingualism has a somewhat muted effect in adulthood but a larger role in older age, protecting against cognitive decline, a concept known as 'cognitive reserve'. We discuss recent evidence that bilingualism is associated with a delay in the onset of symptoms of dementia. Cognitive reserve is a crucial research area in the context of an aging population; the possibility that bilingualism contributes to cognitive reserve is therefore of growing importance as populations become increasingly diverse. 相似文献

This paper examines the activities of churches in Baltimore, Maryland, concerning the issues of sexuality, whether they potentially stigmatize persons with or at risk for HIV/AIDS, and to what extent individual agency versus institutional forces influence churches in this regard. In-depth interviews were conducted with 20 leaders from 16 churches and analyzed using a grounded theory methodology. Although many churches were involved in HIV/AIDS-related activities, the content of such initiatives was sometimes limited due to organizational constraints. Church leaders varied, however, in the extent to which they responded in accordance with or resisted these constraints, highlighting the importance of individual agency influencing churches?? responses to HIV/AIDS. 相似文献

Generalization gradients have been investigated widely in animal conditioning experiments, but much less so in human predictive learning tasks. Here, we apply the experimental design of a recent study on conditioned fear generalization in humans (Lissek et al., 2008) to a predictive learning task, and examine the effects of a number of relevant procedural parameters drawn from the generalization literature in animal conditioning. Experiment 1 shows that prior discrimination learning and steady-state testing procedures sharpen the gradient; Experiment 2 shows that within-subjects testing of the range of generalization stimuli also sharpens the gradient. In addition, Experiment 2 shows that, in case of very flat initial generalization, an orderly gradient can reveal itself through differential rates of extinction learning. Finally, Experiment 2 also evidenced an orderly gradient of generalization-of-extinction. These results suggest that discrimination processes have an important effect on the generalization of predictive learning in humans, and highlight behavioral analogies between animal conditioning and human predictive learning. 相似文献

This longitudinal study examined processes that mediate the association between maternal depressive symptoms and peer social
preference during the early school years. Three hundred and fifty six kindergarten children (182 boys) and their mothers participated
in the study. During kindergarten, mothers reported their level of depressive symptomatology. In first grade, teachers rated
children’s emotion regulation at school and observers rated the affective quality of mother-child interactions. During second
grade, children’s social preference was assessed by peer nomination. Results indicated that mothers’ level of depressive symptomatology
negatively predicted their child’s social preference 2 years later, controlling for the family SES and teacher-rated social
preference during kindergarten. Among European American families, the association between maternal depressive symptoms and
social preference was partially mediated by maternal warmth and the child’s emotion regulation. Although the relation between
maternal depressive symptoms and children peer preference was stronger among African American families than Europrean American
families, its mediation by the maternal warmth and child’s emotion regulation was not found in African American families. 相似文献

Benefits and drawbacks of parental control exercised in relation to adolescents continue to be debated in socialization research with greater emphasis being placed on the benefits of parental autonomy-granting than parental control. We examined the relations between maternal and paternal control and parent–adolescent conflict frequency and intensity as well as parental knowledge of adolescent activities and adolescents’ disclosure of their activities to parents. Adolescents in grades 10 and 12 were interviewed about parenting practices their parents employed when regulating 18 adolescent activities. Thirty-seven parenting practices emerged from which authoritarian, directive, authoritative, democratic, and unengaged parenting clusters were derived. Adolescents whose mothers and fathers were classified as directive or authoritative reported less conflict with parents, more disclosure to parents, and more parental knowledge than adolescents whose mothers and fathers were classified as authoritarian. Coercive control practices of authoritarian parents as well as nondemanding practices of unengaged parents and to some extent of democratic parents were related to more negative parent–child relationship indicators than was the extensive use of firm/confrontive control (rational-demanding) by directive parents or authoritative parents. Evidence herein supports the conclusion that even for middle and late adolescents, parental control that is rational and firm is related to beneficial parent–child relationship qualities. Therefore, practitioners should underscore the importance of continued parental control during adolescence not just of autonomy-granting. 相似文献

In the past few decades, many studies have been conducted on the positive effects of mindfulness, a state of openness to novelty in which an individual actively constructs categories and distinctions. The authors tested the applicability of Langer's ( 1989a ) mindfulness theory to Holland's ( 1997 ) vocational personalities. Data from 156 Israeli full‐time employees were collected. The results link different types of vocational personalities to a mindful mind‐set. 相似文献

We examine how affect and accessible thoughts following a major natural disaster influence everyday risk perception. A survey was conducted in the months following the 2004 south Asian Tsunami in a representative sample of the Swedish population (N = 733). Respondents rated their experienced affect as well as the perceived risk and benefits of various everyday decision domains. Affect influenced risk and benefit perception in a way that could be predicted from both the affect‐congruency and affect heuristic literatures (increased risk perception and stronger risk‐benefit correlations). However, in some decision domains, self‐regulation goals primed by the natural disaster predicted risk and benefit ratings. Together, these results show that affect, accessible thoughts and motivational states influence perceptions of risks and benefits. 相似文献
