Two studies were conducted to investigate the possibility of individual differences in the ability of inpatients to process interactions in group psychotherapy. The first was a pilot study conducted on groups of major depressive patients and matched normal subjects. Subjects were asked to give process comments after viewing simulations of typical group therapy interactions. These comments were later rated on the extent to which they reflected process qualities and accuracy. These data led to a more rigorous and extensive study that included more appropriate control groups as well as measures of potential confounding factors, such as simulation realism, verbal ability, and interaction comprehension. Results indicated that major depressives suffer from deficits in the ability to process group interactions, relative to three types of control groups, including normals. These differences in processing were not significantly positively correlated with any of the potential confounding factors. The implications for understanding interactional processing and group psychotherapy are discussed. 相似文献

The cognitive effects of LOGO were examined among 11–12-year-old black and white Zimbabwean girls and boys. Fifty-two experimental group children were exposed to a BBC LOGO programme with a screen turtle. Forty-one control group children received no exposure to computers at school. Pre-tests on four WISC-R subscales were held in January, 1987 and post-tests on the same four WISC-R subscales were held in November/December, 1987. The data were analyzed with multivariate analysis of covariance, using pre-test scores as the covariate. The results suggested that children in the experimental group did better on the WISC-R Arithmetic scale and that black girls exposed to LOGO showed particular gains in spatial reasoning, as measured by the WISC-R Block Design scale. It is concluded that LOGO appears to facilitate cognitive growth. Methodological limitations of the present study are discussed and suggestions for future research are presented. 相似文献

Cerebral laterality and depression: differences in perceptual asymmetry among diagnostic subtypes 总被引:6,自引:0,他引:6

Examined the influence of diagnostic subtype of depression on perceptual asymmetry for dichotic listening and visual tachistoscopic tasks. A total of 65 unmedicated patients with major depressive disorders and 30 normal controls were tested on a verbal and nonverbal task in each modality. Patients diagnosed according to the DSM-III with melancholia had abnormal perceptual asymmetry for dichotic nonsense syllable and complex tone tasks. In contrast, patients having a nonmelancholic "atypical depression" (reactivity of mood with preserved pleasure capacity and associated features) did not differ from normal controls on these tasks, but had an increased incidence of left handedness. Bipolar depression (history of hypomania) differed from unipolar depression in showing abnormal perceptual asymmetry for a tachistoscopic dot enumeration task. Alterations of perceptual asymmetry in melancholia and bipolar depression were consistent with hypothesized right hemisphere dysfunction. 相似文献

Relations of sociotropic and autonomous personality characteristics to specific symptoms in depressed patients 总被引:2,自引:0,他引:2
A number of writers have suggested that two sets of personality characteristics are associated both with vulnerabilities to depression in response to different classes of events and with different clinical presentations of depression. The present study examined the relations between levels of sociotropic and autonomous personality characteristics and specific, theoretically derived clusters of symptoms in 80 unipolar depressed patients. As was predicted, sociotropy was related to the cluster of symptoms associated with the concept of anxious-reactive depression and was unrelated to the autonomous symptoms cluster. In contrast, the predicted relations of autonomous personality characteristics and symptoms were not found. These results support the idea that the symptom picture in depression may be related to personality characteristics, but they also suggest that the measurement of autonomy may require revision. 相似文献

Clinical neuropsychological findings are examined with respect to competing hypotheses about localized neuropathology in schizophrenia. Two general models of structural and functional impairment are described. The first addresses deficits in cortical/subcortical processes concerned with arousal, attention, and higher cortical functions. The second addresses impairments in the balance of lateralized functions consistent with left hemisphere overactivation. Empirical data provide support for both models, and suggest that the explanatory power of these models may vary when they are applied to different subtypes of schizophrenia. 相似文献

Nonclinical panic in college students: an investigation of prevalence and symptomatology 总被引:2,自引:0,他引:2
This article presents data on the prevalence and symptomatology of panic attacks and panic disorder (PD) in a large nonclinical sample (n = 2,375) of college students. Results showed that approximately 12% of the sample had experienced at least one unexpected panic attack and that 2.36% met DSM-III-R criteria for panic disorder. Although there were no sex differences in overall panic attack prevalence, men reported significantly more panic-related worry than women, and women reported a higher panic frequency than men. Compared to subjects who met DSM-III-R criteria for PD, infrequent panickers presented with fewer panic symptoms, fewer panic episodes, less panic-related worry, lower anxiety sensitivity, and less panic-related avoidance. Moreover, compared with PD subjects, the infrequent panickers were much less likely to report fears of dying, going insane, and derealization during a panic attack. The findings provide preliminary support for the role of anxious apprehension as a psychological vulnerability factor in the pathogenesis of panic disorder. 相似文献

Family functioning of 20 alcoholic male veterans and their female partners was assessed in relation to drinking (wet) and abstinent (dry) intervals. Repeated measures analyses performed on the McMaster Family Assessment Device (FAD) indicated that on all 7 scales of the FAD, alcoholics and their mates perceived family functioning to be better during dry than wet periods. In contrast to their alcoholic mates, female partners gave healthier ratings to all FAD scales except Roles in the dry condition and Affective Involvement in the wet condition. According to published cutoff scores for healthy and unhealthy family functioning, alcoholics as a group viewed their wet and dry family functioning as unhealthy, although the female group regarded the family's dry Problem Solving and Behavioral Control as healthy. These findings suggest that the family functioning of alcohol-involved couples is biphasic, oscillating between drinking and abstinent periods. 相似文献

Typically, family therapy task interventions involve direct assignment of specific behaviors, which may or may not encourage client compliance. To enhance the clinician's probability of bringing about progress in treatment, this article broadens the parameters of task intervention to include (a) Direct versus Indirect, (b) Behavioral versus Nonbehavioral, and (c) Paradoxical versus Nonparadoxical dimension alternatives. The resulting 2 x 2 x 2 model, the Family Therapy Task Construction Paradigm, yields eight possible choices for end-of-the-session punctuation. Each option is linked to corresponding treatment contexts and illustrated with examples from productive case vignettes. 相似文献

We examined the amenability of abstractions of categories to new and relevant information. In Experiment 1, Ss formed impressions of 2 sets of numbers by periodically estimating the cumulative means of each set. During the 1st half of the procedure, the 2 means were mathematically stable. During the 2nd half of the procedure, the mean of 1 set was modified and the mean of the other set remained unchanged. We predicted and found that the resultant estimates for the modified category changed more when the mean difference between the 2 categories was enhanced than when it was reduced. Experiment 2 suggested that the accentuation effect results from a 2-stage process of category learning (Stage 1) and category change (Stage 2). Experiment 3 replicated the effect with person categories. The relevance of category accentuation is discussed with respect to the modifiability of social beliefs. 相似文献
