In order to characterize more completely the nature of the frontal lobe-type cognitive changes in patients with dominantly inherited olivopontocerebellar atrophy (OPCA) we administered two tasks sensitive to frontal system dysfunction, delayed alternation (DA) and delayed response (DR), to 12 patients from one OPCA family. Affected members from this family have previously been shown to have a marked and widespread cerebral (including frontal) cortical cholinergic reduction as severe as that observed in Alzheimer's disease. Performance on DA, but not on DR, was significantly impaired in the OPCA patients compared to that in the controls. We suggest that the DA deficits in OPCA could be a consequence of a loss of cholinergic innervation to orbitofrontal or possibly temporal cortical areas and/or damage to the integrity of the cerebello-frontal neuronal connections. 相似文献

Recruiting help from mentors and other potential helpers is a promising strategy for helping disadvantaged and minority youths meet their personal and educational goals. Three African-American high school seniors participated in a project designed to evaluate the effectiveness of training procedures that would allow them to ask for help in attaining educational and other personal goals. A behavioral training procedure that included instructional materials, role-play practice, praise, and feedback was used. Targeted skills included goal setting and 30 responses involved in the process of meeting with a potential helper. Role-play situations were used to evaluate participants' help-recruiting skills before and after training. Participants increased their help-recruiting skills from an average of 38% during baseline, to an average of 75% after training. Self-reported measures of goal attainment suggested that the students benefited from the training. Implications for mentoring programs designed to increase minority students' opportunities to reach educational goals were discussed. 相似文献

The interface between religion, psychiatry, and ethics is often a locus for considerable controversy. This article focuses on the response of American psychiatry to religious nonconformism, and to religious conversion generally. At issue is the societal pressure against unpopular religious movements. The author argues for an ethic that conserves the freedom of religious conscience, and that guards against inquisitions in the guise of medical expertise and nosology. 相似文献

Early infantile autism was found to be associated with an atypical pattern of cerebral lateralization. Based on EEG measures of hemispheric activation during cognitive processing, it was found that 7 of the 10 autistic individuals tested showed a pattern of hemispheric specialization rarely seen in the normal population; namely, a “reversal” in lateralization reflective of a lack of left-hemisphere specialization for linguistic functions. Furthermore, the autistic individuals' pattern of cognitive strengths and weakness is suggestive of a selective impairment of the left cerebral hemisphere. 相似文献

In a between-subjects design, 46 male and 101 female Australian university students rated a target person described as male or female, overweight or average weight, and wearing glasses or not, on twelve 7-point rating scales. As predicted, a negative stereotype of the overweight person and a complex one of the person with glasses were found. However, there was no significant effect of sex of target except on the ratings of masculine and feminine and no interaction of sex of target with either the glasses or obesity variables. Nor did sex of subject influence the ratings. The results suggest that, although stereotypes of obesity and glasses do exist, they may be as severe for men as for women. 相似文献

The study examined the interactive effects of degree of biculturalism and locus of control on leader behavior in supportive and nonsupportive ethnically mixed small groups. Subjects were 36 male Chicano college students who participated in a small group discussion composed of four members: a naive subject who invariably served as group leader, and three confederates representing distinct ethnic groups (Anglo, Black, and Chicano). Behavioral observations revealed several interesting interactions involving group support. High biculturals, in comparison to low biculturals, adopted a more active leader role in nonsupportive than in supportive groups, asking for more opinions and evaluations, and making more clarification statements. Furthermore, while low bicultural externals and high bicultural internals tended to be more interpersonally assertive and to make more clarification statements under supportive conditions, it was low bicultural internals and high bicultural externals who exhibited the most active leader roles in nonsupportive groups. Additional findings revealed that statements made by the Anglo confederate were clarified more often in the supportive condition, while statements made by either the Black or the Chicano confederate were clarified more often in the nonsupportive condition. The results are discussed in relation to previous literature and the need to develop a more responsive social psychology of interethnic dynamics. 相似文献

Two experiments were carried out to investigate whether visual imagery was used in representing transitive linear ordering relationships. Subjects were presented with passages describing either a linear ordering or a set inclusion relationship, while being subjected to either visual or verbal interference. Performance was tested by asking subjects to judge the truth or falsity of statements concerning both the information presented in the passages and inferences that could be drawn from this information. In neither experiment was there any evidence for the linear ordering material being selectively disrupted by the visual interference task, as would have been predicted by the imagery theory. Thus it is concluded that linear orderings are probably not represented as visual images. 相似文献

Direct biofeedback of blood pressure was compared with frontal EMG biofeedback and with self-instructed relaxation for the treatment of essential hypertension in a controlled group outcome study. Patients were followed up for four months after the end of treatment. Generalization of treatment effects was assessed through pre- and posttreatment measurements of blood pressure under clinical conditions in a physician's office. There were no significant reductions in diastolic blood pressure. The systolic blood pressure (SBP) of the patients receiving blood pressure biofeedback decreased 8.1 mm mercury (p = 0.07) and the SBP of the patients in the relaxation condition decreased 9.5 mm mercury (p = 0.05). In the generalization measures, there were significant reductions in SBP for the relaxation group. The results are discussed in terms of the general lack of replicability within the area of biofeedback treatment of hypertension. 相似文献
