Self-awareness was either manipulated by a mirror (experimental) or not (control). Subjects were selected for being high or low in private self-consciousness (disposition to attend to one's thoughts, feelings, motives). Private self-consciousness had a stronger effect on self-attributions than did self-awareness. These findings have implications for attribution, self-consciousness, and the relationship between manipulations and dispositions.  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

The sensitivity of the scalp-recorded, auditory evoked potential to selective attention was examined while subjects monitored one of two dichotically presented speech passages for content. Evoked potentials were elicited to irrelevant probe stimuli (vowel sounds) embedded in both the right- and the leftear’s message. The amplitude of the evoked potential was larger to probe stimuli embedded in the attended message than to probe stimuli in the unattended message. Recall performance was unaffected by the presence of the probes. The results are interpreted as supporting the hypothesis that this evoked potential sensitivity reflects an initial “input selection” stage of attention.  相似文献

Most personality tests are based on concepts assessing typical performance, and tests of this sort have not been generally successful in predicting criterion behaviors with useful levels of efficiency. Ability tests, which call for maximal performance, have been much more successful as predictors of criterion outcomes. Following a model derived from ability tests, predictors requiring separate typical and maximal self-reports of emotional expressivity were compared to measures of typical and maximal emotional expression in the laboratory. For angry expression, self-reports of maximal expressivity tended to outpredict self-reports of typical expressivity for both typical and maximal laboratory measures of angry expression. Although similar trends were observed for elation, the advantage of maximal self-report measures over typical self-report measures was negligible. Results were discussed in terms of both experimental and clinical implications.  相似文献

In four experiments, subjects read 100-word passages and circled instances of the letter t. Subjects missed a disproportionate number of ts in the word the. Evidence was provided against explanations of this effect involving the location and pronunciation of the t in the and against an explanation in terms of the redundancy of the. Rather the high frequency of the appeared to be critical, and it was suggested that high-frequency words are read in terms of units larger than the letter.  相似文献

The Berger Self-Esteem Measure, the Marlowe-Crowne Social Desirability Scale, and Spence's (1972) Attitudes Toward Women Scale (AWS) were used to test 96 undergraduates. Subjects were divided according to sex and median split scores on the personality measures. Analysis of variance revealed a significant main effect for sex and defensiveness and approached significance for the sex × self-esteem effect (p<.10). Males and females were found to respond significantly differently on the AWS scale. Highly defensive males were more discriminating toward women and self-concept appeared to be an influential variable. However, self-esteem alone did not seem to have any significant effects.  相似文献
