A study of body dissatisfaction, as measured by the Figure Rating Scale (Stunkard, Sorenson, & Schlusinger, 1983) and the
Body Esteem Scale (Franzoi & Shields, 1984), in 75 college women and their mothers indicated that both daughters and mothers
experienced body dissatisfaction. When body size was statistically controlled, either no difference was found between the
groups or daughters were found to have greater body dissatisfaction than mothers. The results supported the hypotheses that
(1) there are generational differences in body dissatisfaction, (2) both cohort and developmental effects contribute to these
differences, and (3) that a developmental effect (mothers' greater body size) may obscure a cohort effect (daughters' greater
exposure to the thin body ideal). Body dissatisfaction measures based on the mothers' retrospective ratings of how they felt
at their daughters' age were consistent with these hypotheses. Relationships between body dissatisfaction and the Sociocultural
Attitudes Toward Appearance Questionnaire (Heinberg, Thompson, & Stormer, 1995) were stronger and more frequent for daughters
than for mothers and for the Internalization Scale than for the Awareness Scale. Relationships between the Ambivalent Sexism
Inventory (Glick & Fiske, 2001) and body dissatisfaction were stronger for mothers than for daughters and for Benevolent Sexism
than for Hostile Sexism. 相似文献

The current study used the partially-baited radial-arm maze paradigm to study the effects of a single-treatment high-dose exposure ('binge') to MDMA (± 3,4-methylenedioxymethaphemtamine or 'Ecstasy') on memory task acquisition. Sprague-Dawley rats were administered a binge dose (4 × 10 mg/kg) of MDMA and their ability to subsequently acquire the radial-arm maze task was compared against saline controls. The MDMA-treated rats were significantly slower to learn the task and made more reference memory errors than the controls. Working memory function was found to be relatively unimpaired. Following a reversal of task rules the MDMA-treated rats were again significantly slower to acquire the appropriate rule despite having eventually achieved a similar level of overall performance as control rats. However evidence of drug tolerance was found when all rats were challenged with an acute low dose of MDMA (1 × 4.0 mg/kg) because the binge MDMA rats were relatively less impaired. Therefore, although binge treated MDMA rats were able to achieve very accurate performance equivalent to the controls they took significantly longer to do this and were less able to adapt their behavior to a change in task rules. In addition the binge treated MDMA rats displayed tolerance to acute MDMA exposure. These findings are consistent with the possibility that human Ecstasy users may show deficits in acquiring information and may experience deficits in cognitive flexibility as well as developing tolerance to the drug with repeated exposure. 相似文献

Support for lateralization of the Whorf effect beyond the realm of color discrimination 总被引:1,自引:0,他引:1
Recent work has shown that Whorf effects of language on color discrimination are stronger in the right visual field than in the left. Here we show that this phenomenon is not limited to color: The perception of animal figures (cats and dogs) was more strongly affected by linguistic categories for stimuli presented to the right visual field than those presented to the left. Moreover, the magnitude of the visual field asymmetry was reduced when demands on verbal working memory were increased by a secondary task. This reduction did not occur when the secondary task imposed demands on spatial working memory. Taken together, these results demonstrate that the lateralized Whorf effect may be quite general, reflecting an interaction of linguistic and perceptual codes primarily in the left hemisphere. 相似文献

God and the government: testing a compensatory control mechanism for the support of external systems
Kay AC Gaucher D Napier JL Callan MJ Laurin K 《Journal of personality and social psychology》2008,95(1):18-35
The authors propose that the high levels of support often observed for governmental and religious systems can be explained, in part, as a means of coping with the threat posed by chronically or situationally fluctuating levels of perceived personal control. Three experiments demonstrated a causal relation between lowered perceptions of personal control and the defense of external systems, including increased beliefs in the existence of a controlling God (Studies 1 and 2) and defense of the overarching socio-political system (Study 4). A 4th experiment (Study 5) showed the converse to be true: A challenge to the usefulness of external systems of control led to increased illusory perceptions of personal control. In addition, a cross-national data set demonstrated that lower levels of personal control are associated with higher support for governmental control (across 67 nations; Study 3). Each study identified theoretically consistent moderators and mediators of these effects. The implications of these results for understanding why a high percentage of the population believes in the existence of God, and why people so often endorse and justify their socio-political systems, are discussed. 相似文献

While recent research using peer ratings demonstrates positive relations between youth's reputations for aggression and popularity, it is not clear whether aggressive youth themselves make these links. Using youth's self‐reports, this study assessed the associations of relational and physical aggression with indicators of both personal gains in peer relations (perceived popularity and receipt of prosocial attention) and personal costs in terms of retaliation or depressive responses (peer victimization and depressive symptoms) in a large sample (n=455) of eighth‐ to tenth‐grade students. Regression analyses reveal that more relationally aggressive youth report more prosocial attention but also more relational (but not physical) victimization. In contrast, more physically aggressive youth report more depressive symptoms and physical (but not relational) victimization. Findings suggest that some costs of aggression (victimization) are higher for boys while others (depressive symptoms) are greater for girls. Group differences were also found for aggressive, victimized, and aggressive/victimized youth compared to the typical low aggressive/low victimized youth. These data suggest that the costs of relational and physical aggression may outweigh benefits except for aggressive non‐victimized boys. Aggr. Behav. 32:409–419, 2006. © 2006 Wiley‐Liss, Inc. 相似文献

After a long time of growth current studies on representative samples of adolescents indicate that the number of adolescent cannabis users in Germany is possibly decreasing. However, it may be presumptuous to expect a similar trend concerning the number of clients with cannabis-related disorders. Even if there is in fact a downward trend which is not yet proven, the rapidly growing number of clients presenting with these disorders in recent years cannot be explained by a similar growth in the number of regular cannabis users. Treatment centres should therefore expect a further inreasing number of especially male adolescents and young adults seeking help for problems related to cannabis use. The development, evaluation and implementation of specific treatment options concerning cannabis use disorders will be increasingly needed in the future. Cognitive-behavioral and motivational interventions have been shown to be evidence-based treatments. The paper describes some promising or already successful treatment approaches and related research projects in Germany. 相似文献
