In order to determine how adolescents perceive their relationships, a set of eight drawings representing one, two or three characters, whose sex and relationships where not clearly defined, were shown to 403 Parisian adolescents (227 girls and 176 boys) aged 15 to 19. The majority of data converge for all subjects, regardless of the sex, curriculum or socioeconomic factors. The subjects consistently identify more mixed-sex dyads and triads than same-sex in all pictures. This predominance does not imply that the adolescents perceived all relationships as having a romantic connotation. Some data seem consistent with the traditional sex role stereotypes. The subjects' responses do not seem to reflect the reality of their own peer relationships. 相似文献

René Magritte was profoundly influenced in his painterly style and in the content of many of his paintings by his mother's suicide when he was fourteen. This paper explores the influence of this traumatic event on his work. My thesis is that the nighttime suicide of Magritte's mother by drowning: (1) had a profound impact on the form and style of his paintings; (2) his paintings represented an effort, mostly successful, to contain and master through intellectual control with isolation of affect the trauma of this experience, which must at the time have evoked helplessness and despair; (3) the contents of a series of his paintings directly reconstruct the traumatic experience under control and in the service of mastery; and (4) there are paintings, mostly painted at the time he clearly developed his own style (1926-1930), that reveal a breakthrough of projected primitive aggressive impulses and unconscious representations of the aggressive mother. In these latter paintings, both form and content are dramatically different from the main corpus of Magritte's work. 相似文献

The effects of anxiety management training were evaluated by allocating 66 generally anxious clients to either a wait list condition, non-directive counselling, or a combination of relaxation and brief cognitive therapy. Anxiety management was significantly more effective than the wait list condition on a number of relevant measures at post-treatment, but there were relatively few differencs between anxiety management and non-directive counselling, either at post-treatment or at 6 months follow-up. Those differences which were found could plausibly be explained in terms of the demand characteristics of training in relaxation or cognitive therapy. It was concluded that anxiety management is clearly better than a non-treatment control condition, but that its superiority to plausible alternatives which lack the specific components thought to be responsible for improvement has yet to be demonstrated. 相似文献
