People differ in the degree to which their identities are based on personal versus social identity characteristics. This experiment tested the hypothesis that people are most concerned about evaluations that are relevant to their salient identity orientation. The Aspects of Identity Questionnaire was used to classify subjects as low or high in personal and social identities. Subjects then anticipated taking a test, believing that their performance would be known by only them, by only a research assistant, by both them and a research assistant, or by no one. Subjects then completed thought-listing and self-report measures of evaluation apprehension. Subjects who scored high in social identity reacted more strongly to the social evaluation than subjects low in social identity. Although subjects high in personal identity were not particularly threatened by private feedback, personal identity seemed to buffer subjects against the threat of social-evaluation. The results are discussed in the context of recent work on private and public aspects of the self. 相似文献

The relationship between mental rehearsal and facial identification accuracy was explored in two experiments involving either a staged classroom event or a video scenario. The results suggest that when subjects rehearsed immediately following an event, compared to subjects in non-rehearsal conditions, identification accuracy was increased when the target face was unchanged in appearance but was reduced when the face was changed slightly in appearance from viewing to test. However, when rehearsal of the event was delayed 10 minutes, identification accuracy was improved even when the face had changed in appearance. Immediate rehearsal, in contrast, led to a reduction in identification performance. In short, in some circumstances the gains in specific memory brought about by mental rehearsal serve to reduce than improve identification accuracy. The relevance of these findings to memory theory and everyday eyewitness testimony is discussed. 相似文献

Psychophysical studies with infants or with patients often are unable to use pilot data, training, or large numbers of trials. To evaluate threshold estimates under these conditions, computer simulations of experiments with small numbers of trials were performed by using psychometric functions based on a model of two types of noise:stimulus-related noise (affecting slope) andextraneous noise (affecting upper asymptote). Threshold estimates were biased and imprecise when extraneous noise was high, as were the estimates of extraneous noise. Strategies were developed for rejecting data sets as too noisy for unbiased and precise threshold estimation; these strategies were most successful when extraneous noise was low for most of the data sets. An analysis of 1,026 data sets from visual function tests of infants and toddlers showed that extraneous noise is often considerable, that experimental paradigms can be developed that minimize extraneous noise, and that data analysis that does not consider the effects of extraneous noise may underestimate test-retest reliability and overestimate interocular differences. 相似文献

In familial breast/ovarian cancer, the information that the proband is able to supply about other family members is of critical importance for genetic counseling. This frequently requires family communication. Forty-six women attending a cancer genetics clinic were interviewed as part of a longitudinal study. Nearly all reported affected maternal, rather than paternal relatives, which may indicate lack of awareness by women with paternal histories. There was also much more communication among female relatives. Mothers, where they were still alive, were key figures in supplying family information. Although the majority of the sample contacted at least one relative regarding counseling, most named a relative with whom they did not feel able to communicate on this subject. Probands balanced the perceived obligation of passing on information with that of not causing alarm. Communication, both obtaining and giving information, was impeded by adoption, divorce and remarriage, family rifts, and large age gaps between siblings. 相似文献

Studied the factor structure of the Behavior Problem Checklist using children from a middle to upper-middle-class suburban school system, determined the extent to which factors generated from children in regular classrooms approximated those generated from children in special education, and examined the effects of class placement, sex, and the interactions of these variables on the average rating children receive on the generated factors. One hundred children from 12 classes for the emotionally disturbed or learning disabled and 527 children from regular forst-through seventh-grade classes were rated by their teachers on the Behaviors Problem Checklist. Following a varimax factor rotation, coefficients of factor congruence and analysis of variance were conducted to test the hypotheses. Results indicated that although teacher ratings of special education and normal children are structurally similar, special education children scored higher on all three factors than did their regular class counterparts. Furthermore, almost all percentages of occurance for individual items were higher for special education children. Further research is suggested to deal with a possible expectancy effect in teacher ratings of problem behaviors. 相似文献

Summary Binocular rivalry was generated by projecting dissimilar Julesz-type patterns to each eye. The minimum angular width of the patterns needed to observe rivalry was measured at four retinal eccentricities for two simulated viewing distances: 200 and 20 cm. The angular width needed to just detect rivalry was up to 50% greater for the 20 cm viewing distance as compared with the threshold width measured at 200 cm. This increased tolerance for rivalry for near fixation was inversely proportional to the change in apparent size. The results suggest that the lateral geniculate nucleus is the site of size-scaling or zooming.Supported by the U. S.
