We investigate the effects of emotional mood states on solving simple pattern comparison tasks. It is assumed that the effects of mood are mediated through response biases as well as effort expenditure. Departing from these assumptions, trend hypotheses are derived for the response biases evaluated by means of a signal detection analysis, for the response latencies, and for an adequate index of the underlying ability. The data support the hypotheses, and in particular, a positive mood state is found to improve performance. The assumption of mood-dependent differences in effort expenditure provides a parsimonious and integrative account of our results, while a reduced-capacity view cannot explain the findings obtained under positive mood induction. 相似文献

Summary In this study on Wilde's phenomenon (Wilde 1950) the two components of disparity, one of them processing displacement, and the other one apparent rotation, are analysed in terms of dependence on the disparity of the end-lines of the pattern (), and on the percentage of magnification (M) of one of the monocular patterns in relation to the other one. It was found that the component of disparity for displacement ' can be expressed as a linear regression equation '=–a+b.The component of disparity for rotation, expressed as a percentage of magnification effective for rotation (M) can be expressed as M=a–b1+b2M.It was concluded that the two components of disparity are processed through independent parallel channels, the processing of the component of disparity for displacement being the faster process, accounting for the larger part of the total disparity. 相似文献

A questionnaire was administered to 47 participants attending a workshop on nuclear energy shortly after publication of a report on a proposed nuclear fuel reprocessing plant. Supporters and opponents of the proposed development differed markedly in their estimates of its possible consequences, and of the relative importance of these consequences. They also differed in their endorsement of pro- and anti-nuclear lobbies, and the factors which they felt contributed most to the “quality of life”. Overall, pro-nuclear subjects appear to place emphasis on the economic benefits of nuclear energy, while anti-nuclear subjects appearad more concerned with social and political risks, and regraded alternative energy sources as more viable. It is concluded that an analysis of such attitudinal differences requires a consideration not only of differences in beliefs, but also of differences in belief salience. 相似文献

The Leipzig Center for Wilson's Disease in the GDR is charged with the registration and diagnosis of all homozygous Wilson gene carriers, the clarification of all suspected cases, including the heterozygote test, and the co-ordination of long-term treatment. At present, there are 78 recorded Wilson gene carriers living. On the basis of our own comprehensive observations and investigations over prolonged periods of time, questions concerning pathogenesis, genetics, diagnosis and therapeutic measures, including their side-effects, are dealt with. 相似文献

A comparison was made of the scores of 171 Japanese boys and 156 Japanese girls, and of 204 English boys and 165 English girls, on the Visual Aesthetic Sensitivity Test. Also compared were 145 male and 163 female Japanese students, with 38 male and 73 female English students. Japanese children had scores significantly higher than English children, while Japanese students had scores significantly lower than English students. There was little evidence of age increments in score for either group of children. Difficulty levels of the 42 item-pairs were very similar in the two cultures, as were internal (split-half) reliabilities. It is concluded that cultural differences between the two countries, as far as visual aesthetic appreciation is concerned, seem at best minimal. 相似文献

Four cases of brain-stem tumor were described, in which myokymias were electromyographically derived from the region of several cerebral nerves. An attempt is made to interpret the effects of twitching by reference to the electromyogram. Myokymias are a positive indication of organic brain stem damage. The use subtle techniques of electromyographic examination shows that this muscular hyperkinesis is not so infrequent a symptom as is generally believed. 相似文献

The scientific basis of psychotherapeutic findings involves a number of difficulties which are above all connected with the insufficient state of basic research in this field. In this situation, significant advances can only be expected on the basis of a systematic long-term investigation and research programme. This applies in particular to the problems of personality and efficiency diagnostics and to group process research. On the basis of some intermediate results, it is shown that by the combined and systematic use of procedures a number of possibilities for the differentiated recording of the complex processes in therapeutic groups can be obtained. 相似文献

Sixteen pairs of successive tones, with different amplitude combinations, were presented with 16 combinations of tone duration and interstimulus interval. A separate group of 12 subjects was assigned to each presentation condition and made comparative loudness judgments for each of the pairs. Perceived within-pair loudness differences were scaled by a Thurstonian method using the subjective width of the "equal" category as the unit. The scale differences were well described by weighted linear combinations of the sensation magnitudes of the tones in the pairs. The time error can be regarded as an effect of this differential weighting. For the longer interstimulus intervals, the weight of the second tone was the greater, causing the usual inverse relation between time error and stimulus intensity level. For the shorter interstimulus intervals, these effects were reversed. An analysis of the pattern of weights led to the development of two models, one of which is a generalization of Michels and Helson's time error model. The weights could be interpreted as reflecting the differential efficiency of the loudness information from the two compared stimuli. 相似文献

The authors report their experience with a special form of psychodrama for the treatment in small groups of neurotic children aged five to fifteen. The acting out of ambivalent, partly unconscious and restrained tendencies and inclinations by playing, i.e., by taking roles in spontaneous performances, is followed by alternation of identification in the group and, possibly, careful indirect verbalization by the therapeutist and/or group, of which the purpose is to arrive at a reorientation of the attitudes of patients and a consolidation of the newly won attitude. 相似文献
