Adolescents tend to categorize themselves and their peers into discrete ingroups and outgroups. A comparison of ingroup versus outgroup perceptions of the characteristics of high-risk youth was investigated. Based on current stereotype research, we examined the perspective that outgroup members would hold a more extreme stereotype of high-risk youth compared to the perceptions of ingroup members. A total of 955 7th- and 10th-grade southern California adolescents completed a questionnaire regarding the characteristics of their own peer group and a high-risk group. Support was obtained for an extremity of judgement effect. Outgroup youth perceived that their high-risk peers engaged in fewer school and nonschool low-risk activities, more high-risk activities, and greater drug use than did ingroup members. Outgroup members also held perceptions of high-risk youth as less likely to hold a white-collar job than did the ingroup members. The perceptions that adolescents have of these groups may play major roles in their own social behavior. The implications of these results for future tobacco use prevention programs are considered.  相似文献

Researchers have increasingly advocated social and developmental psychology perspectives to studying Type A behavior to increase understanding of how it emerges and of how Type A individuals’ entry into different naturalistic social situations may exacerbate their stress reactions. As an initial step in these directions, we tested structural equation models relating components of Type A behavior in adolescents to childhood and adolescent socially problematic behaviors. Results from two high-school district cohorts (Ns = approximately 300 and 700) showed that impatience, hostility, and leadership all were related to childhood problems, but that only impatience predicted an adolescent problem (conflict with friends).  相似文献

The moral right to liberal education involves issues of distribution and of content. The former issue bears on the distribution of educational resources. The latter issue bears on the issue of multiculturalism. Both issues are discussed from the standpoint of equal rights.Presented as the first Distinguished Lecture to the Association for Philosophy of Education at its meeting in New York, 28 December 1991.  相似文献

The recency effect in free recall features prominently in 1960s' theorizing about short-term memory, but has since been largely ignored. We argue that this stems from a preoccupation with the role of recency in the concept of primary memory and the neglect of its role in a broader working-memory framework. It is suggested that the recency effect reflects the application of an explicit retrieval strategy to the residue of implicit learning within a range of cognitive systems. When retrieved implicitly, the same residue is assumed to form the basis of priming effects. The various criteria for implicit learning described by Tulving and Schacter (1990) are successfully applied to the recency effect, and a retrieval process is outlined that can account for both long- and short-term recency effects. It is suggested that a framework combining recency, priming, and implicit learning provides a basis for understanding one of the most important features of cognition and memory, namely, that of maintaining orientation in time and place.  相似文献

The relationship between sex role flexibility and prosocial behavior among preschool children was investigated. Subjects included 16 boys and 18 girls, ranging in age from 36 to 60 months, from intact families of the upper middle class. A nonhierarchical multiple regression analysis was undertaken to determine the contributions of the predictor variables of sex, age, IQ, and sex role flexibility, as well as their interactions with prosocial behavior (criterion variable). Results indicated that while the overall regression model was not significant, the variable of Sex × Sex Role Flexibility did contribute significantly to the model. Inspection of the correlation coefficients associated with this variable revealed that while sex role flexibility and prosocial behavior among boys were significantly and positively related, among girls no significant relationship was found.  相似文献

The potential impact of perceived personal control on coping with a medical threat was investigated in genetic counseling, a clinical setting where issues of personal control are central. Data were collected from 72 counselees at a genetic clinic before, immediately after, and 1 month after initiating genetic counseling. Findings supported the hypothesized mediating model. Higher perceived control (cognitive-interpretive and decisional) and satisfaction with genetic counseling mediated between genetic counseling and the use of less emotion-focused coping strategies. Problem-focused coping was predicted only directly by counselees' knowledge of their problem after genetic counseling. Changes in emotion-focused coping were related to perceived increases in positive affect 1 month later, while changes in use of problem-focused coping were related to perceived decreases in both positive and negative affect.  相似文献
