86 stutterers' disfluency patterns were examined in relation to their laterality preferences. Results suggest that young stutterers are a heterogeneous group and that specific disfluency variables were not related to ear preferences on a dichotic consonant-vowel listening task.  相似文献

This study examined supervisor perceptions and subordinate reactions to formal performance-appraisal reviews. The performance-appraisal behaviors of supervisors and the reactions of their subordinates were studied in a sample of university employees. A factor analysis revealed that there were three dimensions of formal performance appraisals: two developmental dimensions (being supportive; emphasizing performance improvement) and one administrative dimension (discussing pay and advancement). Regression analyses suggested that supervisors supported highly rated individuals and stressed improvement efforts for poor performers. After controlling for the level of previous performance ratings, results indicated that support in the appraisal review was associated with higher levels of employee motivation, while discussing pay and advancement was associated with higher levels of employee satisfaction. Unfortunately, improvement efforts by the supervisors did not influence job performance one year later.  相似文献

The author reports on an improvement in ECT in which Dexamethasone is used to prevent cerebral edema. This improved technique has been used for 823 EC treatment since 1979. Since then, no post-paroxysmal passage syndromes have been observed in gerontopsychiatric patients even in cases where ECT is applied relatively frequently.  相似文献

The authors sum up the most important basic principles of diagnostics and genetics of the schizophrenic psychoses from the viewpoint of genetic counseling for the practising psychiatrist and medical geneticist. Regarding genetic counselling strategy, in addition to nosological considerations, they stress the importance of socio-cultural and social psychological factors and of the emotional atmosphere in the family, which should all be taken into account together. Because of the special situation of schizophrenic (and in general, psychiatric) patients and their families, they regard it as advisable to set up a separate psychiatric genetic counselling service.  相似文献

The relationship between endogenous-psychotic and hysterical behavior is presented in this paper on the basis of typical patients' accounts. Various patterns of behavior are revealed: chronic hysterical psychotic syndromes, acute hysterical psychotic syndromes, hysterical exalted psychotic episodes, simulated hysterical psychotic syndromes, hysterical behavior in the attempt to cope with psychosis, and pseudohysterical behavior in endogenous psychoses. The specific aspects of the doctor-patient relationship in the case of these patients are described.  相似文献

The use of the communication-promoting gesture therapy in a locked psychiatric men's ward led to the result, that a part of the restlessness and aggression potential of the patients could be commuted into a constructive social behaviour. Simultaneous increased frankness and confidence of patients in physicians and male nurses. A tied group doesn't seem to be a condition for that.  相似文献

Hitherto it has not been usual to talk in the German language about the therapy-oriented concept of two forms of the progress of atypical depression (Type A and Type V). The characteristic symptom of Type A is angst, together with phobias, physical complaints, etc. In Type V there are vegetative symptoms, often towards evening (Hypersomnia, difficulty in getting to sleep, increased appetite, increased weight, increased libido), accompanied by hysterical extrovert personality traits, and of intermittent occurrence. These clinical pictures are amenable to psychopharmalogical therapy. In conformity with the assumption of "somatic accommodation" treatment with antidepressives is recommended in the case neurotic depression, too, at least in the initial stages of treatment.  相似文献

15 patients with psychosomatic diseases and the phenomenon of alexithymia, together with neurotic patients are treated psychotherapeutically in half-open groups. Contrary to the neurotics the patients show some special features regarding the process diagnostics. In assessing the wished and really experienced nearness to the group members there is a deficient ability to differentiate. During the therapeutic process the intrapsychic tension (EMI - Inventory of Emotionalities) is subject to great fluctuations or doesn't change. The occurrence of fluctuations in the EMI and of greater differentiations in the N-D-Test (Nearness-Distance-Test) suggest a good prognosis. A therapy of psychosomatic patients together with neurotic patients seems to be more effective than the treatment in homogeneous groups.  相似文献
