INFLUENCE OF ASSESSMENT CENTER METHODS ON ASSESSORS'RATINGS 总被引:2,自引:0,他引:2
WILLIAM H. SILVERMAN ANTHONY DALESSIO STEVEN B. WOODS RUDOLPH L. JOHNSON JR 《Personnel Psychology》1986,39(3):565-578
Recently a number of authors have argued persuasively that performance ratings are influenced to a large extent by the way the rater selects, organizes, stores, and recalls information. Although the influence of the rater's cognitive processes on the obtained ratings has been considered in the job-performance evaluation literature, this issue has not been considered in the assessment center literature. The purpose of the present study was to examine how assessment center methods affect the way assessors organize and process assessment center information and affect the ratings they make. Independent groups of assessors underwent one of two methods for evaluating candidates in an assessment center. Data indicated differences in the convergent and discriminant validities and differences in the factor structures of the ratings for the two methods. The pattern of results suggested that the two methods for evaluating assessment center candidates affected the way the assessors organized the assessment center information and affected the obtained ratings. Future research should consider assessment center methods and assessors as sources of variation in assessment center ratings. 相似文献

The relapse rate of haemorrhages was about 5%. The encephalomalacia existed by way of secondary finding in 24.7%, and the haemorrhage in 2.2%. The investigations showed an important arteriosclerosis by 39.8% in haemorrhages and by 51.6% in brain infarct. It was remarkable by the hypertensive brain haemorrhages a dominant right hemisphere. 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

Significance of psychopathological findings for early detection and prognosis of intracranial tumors
B Sachs 《Psychiatrie, Neurologie, und medizinische Psychologie》1986,38(6):331-336
Psychic findings of 266 patients suffering from cerebral tumor have been analysed. Psychopathological findings, therefore, were among the most frequent symptoms, at the same time being the second most frequent primary symptom after headache. Disturbance of consciousness and orientation were primarily an indication of malign tumors with increase in cerebral pressure whereas disturbance of motive and cognitive functions were more an indication of slowly growing tumors. Despite the same kind of tumors, same localisation and same duration of anamnesis psychic primary symptoms and disturbance of consciousness and orientation have been found considerably more frequently in older patients than in younger patients. 相似文献

The influence in 8 of our patients with ophthalmic migraine of photic driving with sine-like flashing lights on EEG background activity was checked and the visually evoked potentials following the application of diffused simple light stimuli were analyzed using the recovery cycle technique. The results indicate a slightly increased tonic activity of the structures of the mesencephalic formatio reticularis, such as may be produced by slight functional disturbances. Some vegetative secondary symptoms of migraine attacks and some of the changes in EEG observed in patients with ophthalmic migraine are explicable by such an abnormality. 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

The contribution deals with the critical transition from ward treatment and follow-up care as an outpatient. Patients with primary psychic maldevelopment are compared with those of a secondary psychic development. Changes in symptoms and personality were measured with a battery of tests during a pre-post follow-up study (intervals of eight weeks between tests). Special attention is paid to changes after discharge from hospital and deterioration, which was common among the patients with secondary psychic maldevelopment, is discussed. 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
