The present study sought to extend our knowledge of dysphoric adolescents' dyadic peer interactions. Thirty female dyads (ages 13–17) were videotaped interacting during both a structured and an unstructured task. Fourteen of the dyads were each comprised of a dysphoric girl and a nondysphoric girl; the remaining dyads were comprised of two nondysphoric girls. Girls were considered dysphoric if they scored 10 or higher on the Beck Depression Inventory. Dysphoric subjects evaluated their performances more negatively than nondysphoric subjects and rated their partners more negatively overall. The partners of the dysphoric girls were viewed by raters as less positive and less happy. They saw the dysphoric teens as making more critical comments and evaluated them more negatively overall. There was also a tendency for these girls to reject their dysphoric partners and to become more passive during the unstructured task. The findings indicate that dysphoric adolescent girls evoke negative reactions from peers and negatively influence their peers' behavior. These negative reactions from others may lead to further difficulties in negotiating the developmental tasks of adolescence. 相似文献

The effects of selective cholinergic cell loss within the basal forebrain (BF) were determined using a task that requires shifting of attention between two visual stimuli. Discriminability between two stimuli and response bias were determined in young and old F-344 rats given BF injections of IgG-192 saporin (100 ng). The lesion reduced ChAT activity in the frontal and parietal cortices, hippocampus, and olfactory bulbs. The lesion did not significantly alter Na+/K+-ATPase activity in cortex, hippocampus, or olfactory bulbs, or endogenous levels of neuropeptide Y and neurokinin B within the BF. The BF lesions impaired both stimulus discriminability and response bias in young and old rats. The BF lesions had a significantly greater effect upon stimulus discriminability and response bias in aged rats, compared to young rats, only when the stimulus duration was very brief, i.e., when the task was most difficult to solve. At longer stimulus durations, aging and lesions showed no interaction. The results suggest that the selective loss of cholinergic cells in the BF, but not normal aging, impairs the ability to discriminate between independent sensory stimuli. The loss of these cells confers a response bias in simple operant tasks involving motor responses to reward-related visual stimuli. 相似文献

The effect of text difficulty on metamemory for narrative and expository text was investigated. In Experiment 1, we found an interaction between type of text and type of question (thematic or detailed). For readers of narrative texts, correlations between predicted and actual performance were highest for detailed questions, but this pattern was reversed for readers of expository texts. Next, text difficulty was explored as a possible factor affecting metamemory accuracy. In Experiments 2 and 3, metamemory accuracy was a nonmonotonic function of text difficulty. Subjects made remarkably accurate predictions of future performance (meanG > .6) for both narrative and expository texts that were of intermediate difficulty (approximately a 12th-grade reading level). We propose anoptimum effort hypothesis, predicting greatest metamemory accuracy when the texts are of intermediate difficulty. 相似文献

To apply group therapy or counseling, a branch of helping methodology rooted in modern Western psychology, to a culturally different context, such as the Chinese cultural environment, group counselors need to increase their awareness, knowledge, and skills that are compatible with the group climate they encounter. A group counselor needs to understand the general characteristics of the culture. The counselor should use his or her leadership quality to deal appropriately with group clients' psychological dynamics, which bear unique cultural preferences with respect to thinking, feeling, and doing. While many group counseling communication skills from a Western theoretical framework can be helpful and applicable to the Chinese group clientele, some of these skills need to be contextually modified. The counseling goal is to properly integrate Chinese cultural and therapeutic norms into the group process.He also teaches as a Sessional-Instructor in the same department. 相似文献

Despite frequent mention, we know relatively little about the effect of ambient environmental factors on consumer behavior. This paper discusses one important aspect of the environment, ambient scent. Based on research from several disciplines, a model describing the effect of ambient scent on consumers is propossed. Ambient scent is portrayed as an environmental cue that is compared with scent preferences to influence affective responses and ultimately approach-avoidance reactions. Moderators of these presumed relationships are also described. Suggestions for empirical research are provided and implications for marketing management are presented. 相似文献

Following Haring's (1992) recommendation, we have utilized qualitative research techniques to assist us in designing a program of research on inclusive education which is responsive to the outcome values and priorities identified by teachers and parents. Using interviews, observations, and document analysis to follow 35 children in full inclusion classrooms over a period of two years, we have described outcomes for these children in three major domains. These outcome domains, and subthemes within them, have been evaluated and revised based on interviews and social validation ratings by parents and teachers. Dependent measures based on our qualitative research findings are currently being used in a series of behavior analytic studies designed to evaluate the effects of specific interventions on outcomes of inclusion for children with and without disabilities. 相似文献
