Although peers' and teachers' evaluations of children's prosocial behavior and peers' sociometric ratings frequently have been used in studies of social development, the validity of young children's ratings of others has been questioned, as has that for teachers' ratings of prosocial behavior. In this study, preschoolers' ratings of peers' sociometric status and prosocial behavior, as well as teachers' ratings of children's prosocial dispositions, were obtained. These were correlated with children's naturally occurring prosocial or social behavior; ratings of prosocial behavior also were correlated with children's prosocial moral reasoning and prosocial self-attributions. Peers' sociometric ratings were positively related to children's sociability whereas prosocial ratings were related to helping (but not sharing) behavior. Teachers' ratings of prosocial behavior were not related to frequency of prosocial behaviors, but were positively related to developmentally mature moral judgments and self-reported motives. 相似文献

This binational study explored the need importance patterns and involvement in work and family contexts. Results reveal that in the work context, growth needs are most important, followed by affiliative and subsistence needs. In the family context, affiliative needs are most important, followed by subsistence and growth needs. Involvement in work and family contexts was found to be influenced by the need satisfaction potential of the respective contexts. This explained the nature of relationship between work and family involvement. The cross-national generalizability and usefulness of a motivational model for research on involvement in multilife-spheres are discussed. 相似文献

This paper combines the results of two studies across different cultures which included an investigation into the relationship between field-dependence-independence and vocational orientations within the framework of Holland's theory of career choice and Witkin's theory of psychological differentiation. The samples included 179 Canadian senior high school students and 376 Pakistani college and university students. Both samples were administered Self-Directed Search and Group Embedded Figures Test. The results indicated a significant relationship between cognitive styles and vocational orientations. It was evident from the findings of these two studies that the theories of Holland and Witkin dove-tail nicely with each other. 相似文献

At 1 year postpartum, 22 of 38 couples demonstrated the same level of marital competence as they had prenatally, 14 couples demonstrated deterioration in their marital relationship, and 2 couples were improved. At each of four levels of marital competence, there was a trend for the couples to demonstrate the same relationship response to parenthood. Highly competent relationships remained at high levels of competence. Competent but pained relationships were most vulnerable to regressive change in structure. Dominant-submissive, complementary relationships tended to remain stable at that level. Dominant-submissive, conflicted or severely conflicted relationships were most unpredictable and stability, regression, and improvement were seen. These findings are explored for possible correlations and are discussed from the perspective of several current models of family development. 相似文献
