Many studies point directly to the role played by sex roles and indirectly to the role played by gender identity in the onset of disordered eating. In this study, women who report adhering to nontraditional sex role aspirations are almost twice as likely as other women to report purging or frequent bingeing. Women who exhibit gender identity conflict by drawing a male or androgynous figure on the Draw-A-Person Test or by reporting a pattern of wishing they had been born a male are more likely than other women to report purging or frequent bingeing. The results are consonant with a hypothesis regarding the etiology of disordered eating that implicates gender identity conflicts among women, particularly women who exhibit nontraditional sex role aspirations. 相似文献

This experiment tests the hypothesis that relative to nondepressed college students, depressed college students will underestimate the potential amount of control they can exert over an environmental outcome when they must generate a complex hypothesis in order to exert control, but not when the complex hypothesis is generated for them. Following the method of Alloy and Abramson (1979b), depressed and nondepressed students' judgments of response-outcome contingency were assessed in either a ‘self-generated’ or an ‘experimenter-generated’ condition. In the ‘self-generated’ condition, subjects generated and tested potential hypotheses for controlling the outcome themselves. In the ‘experimenter-generated’ condition, the experimenter generated a small set of potential hypotheses to be tested by the subject. Relative to nondepressed students, depressed students were less likely to perform the correct controlling response, received fewer rewards, and judged that they exerted less control over the outcome in the ‘self-generated’ condition. These results fail to support the ‘associative’ deficit of the learned helplessness theory of depression, but are consistent with the ‘motivational’ deficit of helplessness theory. 相似文献

One hundred and forty-eight undergraduate women were orally instructed to repeatedly and quickly draw circles in spatial relation to squares printed on sheets of paper. On each trial, the instructions required the circle to be drawn either above, below, to the right of, or to the left of the square. The instructions were expressed so that the circle was either the logical subject (e.g., "circle above square") or the logical object (e.g., "square below circle") of the statement. Each subject received all experimental conditions for a total of 24 separate drawings per subject. Analysis of variance of the total number of errors disclosed significant effects of all experimental variables. Performance was significantly more accurate when the circle was the logical subject, when the orientations were "above" and "right of" rather than "below" and "left of" and for the vertical dimension. The results are discussed in terms of current theories on "asymmetries" in information processing. 相似文献

Since socialization is a learned process, it has been hypothesized that through a group experience individuals might be assisted to develop improved interpersonal relationships, improved self-confidence, and more relevant work attitudes and, thus, might be assisted to improve their employability. A questionnaire was devised in order to study the utilization and practice of group guidance in an Employment Service setting. 相似文献

This experiment tested alternative explanations of list method directed forgetting effects. Two word lists were studied by 135 subjects. Between lists, subjects were instructed to remember both lists (remember group), remember both lists as well as in which list words were studied (segregate group), or to forget the first list and remember the second (forget group). All subjects took both recall and recognition tests with test order varied between subjects. Among subjects who took the recall test first, the forget group showed a directed forgetting effect (poorer performance on List 1 than List 2) with both recall accuracy, recall typing time, and recognition reaction time measures. Contextual segregation of List 1 words by forget subjects was ruled out as a sufficient cause of the effect. Limited support was obtained for a differential rehearsal explanation of the effect. Within-group comparisons and findings of release from directed forgetting support inhibitory processes as the major cause of the directed forgetting effect. 相似文献

A large school-based sample of children in Grades 1, 2, 3, and 4 were screened for disruptive behavior and subsequently assessed over a 5-year period for DSM-III-R symptoms of attention deficit hyperactivity disorder (ADHD) and other externalizing and internalizing behavior disorders. Parents completed structured diagnostic interviews in Years 1, 4, and 5, and teachers completed Behavioral Assessment for Children—Teacher Rating Scales behavioral ratings annually. For parent-derived diagnostic data, both inattention and hyperactivity/impulsivity symptom groups declined from Year 1 to Year 4, with hyperactivity showing more significant decline. For teacher-rated behavioral dimensions, the Attention Problems scale declined from Year 1 to Year 3 and stabilized thereafter. The Hyperactivity scale showed stability during the first 3 years before declining in Year 4. Of those children diagnosed with ADHD in Year 1, 69% still met criteria for ADHD in either Year 4 or 5. Persisters were more likely to exhibit coexisting conduct disorder in Year 1 and oppositional defiant disorder in Years 1, 4, and 5. Parents of persisters reported more psychosocial adversity on measures of parenting and marital satisfaction. 相似文献
