The purpose of the present study is to provide a perspective on the recognition of other-race faces, i.e., black faces by white subjects. Past research has indicated that individuals have greater difficulty recognizing other-race faces than they do same-race faces. On the basis of previous findings, we chose to investigate the recognition of black faces by white subjects as a function of the quantity and quality of previous experience with blacks, racial attitudes, field dependence/independence, and recognition training. Forty-two white subjects participated in pre-, post-, and delayed recognition tests. Subject data were also collected to explore individual differences in recognition performance. Using multiple regression techniques, it was found that field dependence/independence accounted for the largest proportion of variance in recognition performances; a feature-discrimination training task and past experience with blacks were also found to significantly relate to recognition performance. The applied aspects of these results are discussed. 相似文献

Sixteen observers palpated silicone models of human breasts containing lumps 1.6-12.1 mm in diameter. Detectability depended on the size of the lump, producing a systematic psychometric function. In eight observers who participated in three or more sessions, performance improved with practice, with most improvement occurring within one or two 26-trial sessions. Three-week retention measures disclosed no appreciable decrease in performance, but a significant correlation was found between the number of lumps detected and duration of trial (p < .01). There was no difference in performance between four observers who used their preferred hands and four observers who used their nonpreferred hands. These data establish that examination of breast models for the detection of lumps simulating cancer is a task amenable to experimental analysis. 相似文献

Untreated rats were observed to either bite or box with Pentobarbital-treated opponents in a shockelicited aggression situation. Specific behaviors such as ataxia movements and submissive postures immediately preceded biting attacks, but rarely boxing whereas behaviors such as moving around the chamber and upright threat postures immediately preceded boxing attacks, but rarely biting. These data suggest that the topography of aggressive behavior of an attacking rat is determined by the behavior of the victim. 相似文献

Fifteen hermaphroditic females with the adrenogenital syndrome received corrective, androgen-suppressing therapy with cortisone from birth onward. They were studied psychologically in late adolescence and adulthood, with particular attention to a possible long-term effect of fetal androgenization on aggressive manifestations. No such effect was evident. The girls were tomboyish in the manner previously reported for the adrenogenital syndrome. 相似文献

OBJECTIVE: To examine the influence of parental solicitousness on self-reported somatic complaints in school-age children. DESIGN AND MAIN OUTCOME MEASURES: Participants were 564 children (mean age 10 years) and their parents. Children completed self-report measures of somatic complaints, parental solicitousness, depressiveness, fear, and sense of coherence. Somatic complaints were assessed again 6 months later. Parents also completed a questionnaire about solicitousness. RESULTS: Parental solicitousness as reported by children or parents was unrelated to the frequency of self-reported somatic complaints. Symptoms of depression, fear, and lower sense of coherence were associated with more somatic complaints, but did not interact with parental solicitousness. CONCLUSION: Parental solicitousness seems unrelated to more frequent somatic complaints in schoolchildren. 相似文献
