Ethnic differences in adolescent achievement. An ecological perspective. 总被引:15,自引:0,他引:15
Using data collected from a large sample of high school students, the authors challenge three widely held explanations for the superior school performance of Asian-American adolescents, and the inferior performance of African- and Hispanic-American adolescents: group differences in (a) parenting practices, (b) familial values about education, and (c) youngsters' beliefs about the occupational rewards of academic success. They found that White youngsters benefit from the combination of authoritative parenting and peer support for achievement, whereas Hispanic youngsters suffer from a combination of parental authoritarianism and low peer support. Among Asian-American students, peer support for academic excellence offsets the negative consequences of authoritarian parenting. Among African-American youngsters, the absence of peer support for achievement undermines the positive influence of authoritative parenting. 相似文献

Tversky, Rinott, and Newman (Journal of Mathematical Psychology, 1983, 27, 000) examine the asymptotic behavior of a measure of the centrality of the nearest neighbor relation. The applicability of their conclusions when the number of dimensions (d) and the number of points (n) take on the small-to-moderate values commonly encountered in the analysis of proximity data is investigated. The results suggest that convergence is fast when n is large relative to d and slow when d is large relative to n. 相似文献

A rational reconstruction of the role of moral values in diagnostic reasoning is undertaken. In the context of a case study it is shown how value and ethical considerations come into play in the complex course of making diagnostic and therapeutic decisions. 相似文献

The relationship between the phonological characteristics of young children's unsolicited imitative and spontaneous speech was examined as a function of (1) the level of the children's linguistics development, and (2) the children's knowledge of the words imitated. A greater number of phonological discrepancies were seen in children with lexicons of fewer than 40 words than in children with larger lexical repertories. Such discrepancies were also more likely when the children displayed little comprehension of the words they were imitating. This tendency was particularly strong in the children with limited lexicons. The results are discussed in terms of a developmental shift in the bases of children's phonological organization. 相似文献

Neuropsychological studies of delinquents have revealed characteristic deficits in skills that require verbal mediation, conceptual integration, impulse control, anticipation of consequences of actions, and the utilization of feedback from behavior to modify maladaptive response patterns. Formulations of this impairment pattern in terms of frontal lobe and left hemisphere dysfunction are reviewed. The role of verbal mediation in the development of a stable personality and the capacity for self-control is discussed. It is proposed that the neuropsychodynamic profile of the delinquent is dominated by an inability to form a self-referential conceptual classification system and that this predisposes to behavioral disinhibition under conditions of stress or interpersonal conflict. The relationship between language development, moral cognition, and social behavior is examined and therapeutic and dispositional implications are discussed. Finally, the general role of neuropsychological models in personality and social theory is addressed. 相似文献

In this article, we report two experiments in which various measures thought to be related to hypnotizability were analyzed by stepwise discriminant analysis techniques. Absorption (Tellegen, 1981, 1982; Tellegen & Atkinson, 1974) and preference for an imagic style of thinking (Isaacs, 1982) were robust predictors of hypnotizability; each variable accounted for significant variance in hypnotizability at their respective steps in two samples and correctly classified a significant proportion of low- and high-hypnotizable subjects in the discriminant analyses. The addition of two other variables in Experiment 2--a Sleep-Dream score derived from Evans's (1977) Cognitive Control of Sleep Mentation subscale and Gibson's (1985) Dream Questionnaire, and the Belief in the Supernatural subscale of the Taft (1969) Experience Questionnaire--increased the correct classification of the medium-hypnotizable subjects from chance levels to 74%. It is argued that a confirmatory and hierarchical approach is needed in future studies to explore correlates of hypnotizability more fully. 相似文献
