Longitudinal data spanning early (30s) and older (late 60s/mid-70s) adulthood were used to study spiritual development across the adult life course in a sample of men and women belonging to a younger (born 1928/29) and an older (born 1920/21) age cohort. All participants, irrespective of gender and cohort, increased significantly in spirituality between late middle (mid-50s/early 60s) and older adulthood. Members of the younger cohort increased in spirituality throughout the adult life cycle. In the second half of adulthood, women increased more rapidly in spirituality than men. Spiritual involvement in older age was predicted by religious involvement and personality characteristics in early adulthood and subsequent experiences of negative life events. 相似文献

Ninety-five percent of the 30 million foreign-born persons living in the United States reside in a metropolitan area, and more than one half reside in just six gateway cities. We investigate whether less-educated immigrants tend to settle in large urban communities of their compatriots. Based on statistical analysis we find a negative relationship between the level of education and the size of immigrant population for the immigrants born in China, India, Philippines, Korea, El Salvador, Cuba, and Mexico. The relationship is strongest for Chinese, with a decrease of 2.7 years in average educational attainment for each tenfold increase in the size of immigrant community. Generally, this relationship is stronger for the immigrants from Asia and Latin America and nonexistent or mixed for immigrants from Europe and Canada. 相似文献

Although a few developmental fMRI studies have shed some light on the neurological development of either object or spatial processing we still know very little about the development of the ‘what’ and ‘where’ processing systems. The present study is the first to address this issue by comparing, concurrently and within the same behavioral paradigm, patterns of functional activation for face processing and location processing in 12 children (10–12 years old) and 16 adults. For both tasks this study found a developmental shift from a more distributed pattern of activation in children to a more focused pattern of activation in adults. Furthermore, the type of developmental redistribution of activation in children varied depending on the task. The present findings have important implications for theories of visuospatial development. They suggest that the neural systems involved in face and location processing may undergo development and fine‐tuning well into late childhood. 相似文献

The present study examines how individuals with different social value orientations (i.e. prosocial, individualistic, and competitive) construe the rationality, morality, and power of choices in four distinct interdependence structures which systematically differ in the motives that could underlie the most prosocial or least aggressive choice: (a) altruism only, (b) altruism and cooperation, (c) altruism, cooperation, and individualism, and (d) altruism, cooperation, individualism, and competition. Results revealed that rationality ratings, and to a lesser degree morality and power ratings, increased most when the motives that could underlie a choice were part of the perceiver's social value orientation. Overall, the pattern of rationality ratings provided reasonable support for the Goal Prescribes Rationality Principle. Ratings of morality and power suggested a corresponding Goal Prescribes Morality/Power Principle (for prosocials and individualists), but revealed only mixed support for the Might Over Morality Hypothesis.

An experiment (N = 98) investigated the moderating effect of ingroup identification on reactions to deviant ingroup members. We measured psychology students' level of identification with the group ‘psychologists’ and presented them with information about either a normative or deviant psychologist. Participants completed an ingroup stereotype measure either before or after reading about and evaluating the target psychologist. High identifiers expressed a more positive stereotype of the ingroup after, compared to before, reading about a deviant ingroup member. High identifiers also expressed a more positive stereotype of the ingroup after reading about a deviant than after reading about a normative ingroup member. By contrast, low identifiers' stereotype judgements were relatively unaffected by the target information. The target evaluation ratings indicate that high identifiers were more positive than low identifiers towards the normative ingroup member, but were more negative than low identifiers towards the deviant. The results point to the greater motivational demands on high identifiers to maintain a positive image of the group. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

Previous research has shown that individuals high in benevolent sexism positively evaluate women who conform to traditional gender roles (e.g., Glick, Diebold, Bailey-Warner, & Zhu, 1997). In the current study, male and female participants completed the Ambivalent Sexism Inventory (Glick & Fiske, 1996) and a new measure of paternalistic chivalry, that is, attitudes that are both courteous and considerate to women but place restrictions on behavior considered appropriate for women during courtship. Consistent with our hypotheses, benevolent sexism was significantly positively related to paternalistic chivalry. Hostile sexism and participant sex were unrelated to paternalistic chivalry. 相似文献

Cognitive development of lead exposed children from ages 6 to 15 years: an application of growth curve analysis. 总被引:2,自引:0,他引:2
The effect of lead exposure on cognitive growth patterns was assessed in a longitudinal study of 196 children. Performances on tests of verbal comprehension and perceptual organization (Vocabulary & Block Design, Wechsler Intelligence Scales for Children) were measured at ages 6.5, 11 and 15 years. Growth curve analyses revealed that the quadratic model best described the relationship between test scores and age. Children with higher lead levels, as measured at age 15 years, demonstrated lower verbal comprehension scores over time and greater decline in their rate of Vocabulary development at age 15 years, as compared to children with lower lead levels. Lead exposure was not significantly associated with growth in perceptual organization test scores. Socioeconomic status and maternal intelligence were statistically significantly associated with growth patterns for both test scores, independent of the effects of lead. The findings suggest that lead negatively impacts the developmental progression of specific cognitive skills from childhood through adolescence. 相似文献

Remarkably little is known about what underlying processes and mechanisms lead to effective change in career counseling. This article examines potential reasons why career counseling process research has been infrequently conducted and provides 10 avenues from psychotherapy process research, and the limited pool of existing career counseling process research, that hold promise for advancing a productive process-research agenda in career counseling. These 10 avenues include: (a) examining the working alliance and five promising counselor techniques; (b) reconceptualizing career counseling as a process of learning, and investigating the processes that lead to effective learning; (c) investigating differences in career counseling process and outcome due to subtype membership, cultural perspectives, and other critical client attributes; (d) investigating differences in career counseling process and outcome based on counselors’ levels of self-efficacy, cultural perspectives, and other critical counselor attributes; (e) examining influential session events; (f) utilizing a common problem resolution metric for examining change across clients; (g) examining client change longitudinally to examine stability of change and functional practicality of assessed outcomes; (h) examining cognitive processes that may be mediating the career counseling process; (i) developing molecular and global taxonomies of counselor behaviors; and (j) utilizing advances in methodological approaches and statistical analyses. 相似文献

How does self-efficacy affect interest? The interest-and-interests model assumes that factors that induce interest—novelty, complexity, conflict, and uncertainty—do so non-linearly. Self-efficacy should thus affect interest quadratically, because it reflects uncertainty about an activity’s outcome. When self-efficacy is low, interest is low because the activity’s outcome is certain. When self-efficacy is moderate, the person’s success on the task seems likely, but not inevitable. But as self-efficacy becomes very high, success seems completely certain, and the task is thus uninteresting. Two experiments tested these predictions. Experiment 1 asked people to rate the interestingness of differentially difficult activities; Experiment 2 manipulated self-efficacy regarding a fuzzy dart game. In both experiments, interest was a quadratic function of self-efficacy. Implications for theories of vocational interest development and change are considered. 相似文献
