One-hundred and ninety-two children (equally split between boys and girls) were studied when they were 5 years old in two settings, school and home. The children were observed in playgroups and at home, and were rated on activity level by their parents on the Rothbart Child Behavior Questionnaire. At age 7, the children were tested in our laboratory on the Harter Test of Perceived Competence and on an achievement task, and parents filled out the Child Behavior Checklist, the Child Behavior Questionnaire, and the Conners Parent Rating Scale. Home observations of activity level were significantly related to parent ratings of activity level, but not to school observations. Activity level at age 5 was related to parents' ratings of aggression and hyperactivity and to girls' learning problems at age 7. Activity level was not related to the children's self-perceived competence, but mothers' rating of high activity level at age 5 was related to low reading comprehension at age 7.Preparation of this paper was supported in part by the Center for Research for Mothers and Children, NICHD, U.S. PHS grant HD 19739 to Beverly I. Fagot.  相似文献

This study is one of a series of investigations examining the contribution of sex roles to the development of depression within a learned helplessness framework. Utilizing 143 pairs of undergraduate female participants, the present study explored subjects′ abilities to gain and maintain control in an interpersonal context. Interpersonal control was operationalized as successful persuasion in a two-person discussion task, wherein one participant had hidden instructions to be maximally persuasive in discussing a questionnaire about social behavior. The results indicated that less successful persuasion was associated with increases in depressed mood. Furthermore, women with high masculinity and low femininity were able to gain interpersonal control regardless of the sex role of their partner. The results also suggested that high femininity is associated both with giving up control in interpersonal tasks and with increases in depressed mood when one is faced with the task of exerting interpersonal control. The findings were interpreted in terms of the importance of sex role characteristics in learned helplessness and depression.  相似文献

African American women's sexual satisfaction in heterosexual relationships was examined as a dimension of their sex roles. Responses to questions about sexual behaviors and interactions they preferred in primary relationships were selected from a larger study of a stratified random sample of 126 African American women. Three factors were identified: sexual responsiveness, sexual expression, and sexual interest and enthusiasm. The factors are described as profiles that may enhance or limit women's male-female sexual relationships. The implications of African American women's sexual satisfaction as an important dimension to understand in today's AIDS related sexual climate is discussed within a socio-cultural context.A modified version of this paper was presented at the American Anthropological Association, November 1987, Chicago, Illinois. The research was funded by The Center for Prevention and Control of Rape, NIMH Grant, R01 MH33603 and through a Research Scientist Career Development Award to the first author, K01 MH00269.  相似文献

A total of 229 late adolescents (a large majority 15 to 19 years of age) completed a questionnaire that assesses a broad range of videogame-relevant experiences, preferences, and attitudes. Videogame playing was found to be a more popular, and a more highly regarded, activity among males than females. Gender differences were also found in participants' ratings of their motivations for playing videogames, their evaluations of particular characteristics of videogames, and their selection of their “most favorite” videogame. The differences between frequent and infrequent videogame players appeared to be limited to differences in the extent to which videogame playing is pursued and evaluated as a positive leisure activity, rather than reflecting broad differences in interest or personality. Some relations were found between participants' self-reported personality characteristics (i.e., self-esteem, empathy, conscientiousness, and introversion) and their attitudes toward videogames.  相似文献

ABSTRACT College students who had yet to marry and begin a family were asked about their desire to have children and their beliefs and expectations about themselves as parents (Study 1) and the characteristics of their prospective children (Study 2). Persons with more avoidant and anxious-ambivalent models of close adult relationships harbored more negative models of parent-hood and parent-child relationships. These findings indicate that working models of parenting and parent-child relationships form well before marriage and the birth of children and that these models are systematically associated with attachment styles in adult relationships. The findings also suggest ways in which insecure attachments between child and parent may be influenced by the caregiver's models of parenting and parent-child relationships.  相似文献
