Response Style Theory [S. Nolen-Hoeksema (1987) “Sex Differences in Unipolar Depression: Evidence and Theory,” Psychological Bulletin, Vol. 101, pp. 259–282] suggests that, when depressed, women ruminate on their sad feelings while men distract themselves from theirs. We sought to examine this gender difference in more detail. In Study 1, 155 students provided stereotype ratings or self-reports of responses to depression. The stereotype ratings conformed precisely to Response Style Theory yet exaggerated self-reported gender differences, especially for men. In Study 2, 40 roommate pairs completed a similar set of ratings. Again, other-ratings conformed exactly to Response Style Theory's predictions while self-ratings showed a more moderated pattern. In both studies, women reported ruminating more than did men, yet men and women were equally likely to report distraction. We conclude by examining several hypotheses for the discrepancies between stereotypes and self-reports for men as well as the increased rates of rumination among women. 相似文献

Using a classical conditioning technique, this study investigated whether nonconscious associative learning could be indexed by event-related brain activity (ERP). There were three phases. In a preconditioning baseline phase, pleasant and unpleasant facial schematics were presented in awareness (suprathreshold). A conditioning phase followed, in which stimuli were presented outside awareness (subthreshold, via energy masking), with an unpleasant face (CS+) linked to an aversive shock and a pleasant face (CS−) not linked to a shock. The third, postconditioning phase, involved stimulus presentations in awareness (suprathreshold). Evidence for acquisition of a conditional response was sought by comparing suprathreshold pre- and postconditioning phases, as well as in the subthreshold conditioning phase itself. For the pre-postconditioning phase analyses, significant ERP component differences differentiating CS+ and CS− were observed for N1, P2, and especially P3. For the conditioning phase, significant differences were observed in the 100–400 ms. post-stimulus region reflecting a CS+ processing negativity. Brain activity does indeed index the acquisition of a conditional response to subthreshold stimuli. Associative learning can occur outside awareness. 相似文献

The Child and Adolescent Functional Assessment Scale (CAFAS) is a multidimensional measure of degree of impairment in functioning. Interrater reliability data are presented for lay raters, graduate students, and frontline staff. Reliability was high for the total score and behaviorally-oriented scales. Construct, concurrent, and discriminant validity were assessed with the sample of children and adolescents evaluated at the Fort Bragg Demonstration Evaluation Project. Youth and their caregivers were evaluated via interview and selfcompleted instruments at four time points. Significant correlations were found between the CAFAS and other related constructs. Concurrent validity was demonstrated by logistic regression analyses examining the relationship between CAFAS ratings and problematic behaviors endorsed on measures completed by parents, teachers, or the youth. Youth with higher CAFAS total scores were much more likely to have poor social relationships, difficulties in school, and problems with the law. Discriminant validity was assessed with a repeated measures analysis of variance with intensity of care at intake and time as factors. Youth who were inpatients or in residential treatment centers at intake had higher CAFAS scores than those who were outpatients. These findings provide strong evidence for the reliability and validity of the CAFAS. 相似文献

Rehearsal in Spatial Working Memory: Evidence From Neuroimaging 总被引:7,自引:0,他引:7

A variety of biological evidence has identified a frontal-parietal circuit underlying spatial working memory for visual stimuli. But the question remains, how do these neural regions accomplish the goal of maintaining location information on-line? We tested the hypothesis that the active rehearsal of spatial information in working memory is accomplished by means of focal shifts of spatial selective attention to memorized locations. Spatial selective attention has been shown to cause changes in the early visual processing of stimuli that appear in attended locations. Thus, the hypothesis of attention-based rehearsal predicts similar modulations of visual processing at memorized locations. We used functional magnetic resonance imaging to observe posterior visual activations during the performance of a spatial working memory task. In line with the hypothesis, spatial rehearsal led to enhanced activation in the early visual areas contralateral to the memorized locations. 相似文献

Models describing the role of source credibility in information integration were tested in two experiments. In the first experiment, subjects estimated the value of used cars based on two cues: blue book value and an estimate provided by one of three friends who examined the car. The three sources were described as differing in mechanical expertise. In the second experiment, subjects rated the likeableness of persons described by either one or two adjectives, each adjective contributed by a different source. The sources differed with respect to the length of their acquaintance with the person to be rated. In both experiments, credibility of the source magnified the impact of the information he provided. Further, this multiplicative effect of a source was inversely related to the credibility of the other source, in violation of additive or constant-weight averaging models, but consistent with a relative-weight averaging model. 相似文献

Two studies were conducted to assess and train clinical interviewing skills. In Experiment 1, eight university practicum students (“therapists”) and either role played or volunteer “clients” were audiotaped during simulated interviews. Following the collection of baseline data on both therapist and client responses, training was provided by way of written materials, classroom instruction and practice, and quizzes. Results of a multiple baseline design across subjects showed improvements in therapists' interviewing skills and subsequent increases in client responding. Experiment 2 replicated and extended the research to a hospital outpatient clinic, in which therapists interviewed the parents of children with behavior problems. In addition, four months following the completion of Experiment 2, follow-up data collected during a maintenance condition showed continued high levels of therapist and client behavior. Finally, a panel of expert peers indicated that each response category was judged highly relevant to the behavioral assessment process. 相似文献
