This research examined how efforts to ensure demographic diversity in a work group affected perceptions of the competence of individuals who are likely targets of such efforts. In three experiments, 262 undergraduates gave their impressions and performance expectations of members of a group assembled to work on a task. When a diversity rationale rather than a merit rationale was provided for how the work group was assembled, both women (Studies 1 and 2) and Black men (Study 3) were perceived as less competent and were expected to be less influential. This effect occurred regardless of the proportional representation of women or the degree of the groups' heterogeneity. The diversity rationale also produced more negative characterizations than did another non‐merit‐based rationale: scheduling convenience. 相似文献

This study investigated developmental and sex-related differences in affective decision making, using a two-deck version of Children's Gambling Task administered to 3- and 4-year-old children. The main findings were that 4-year-old children displayed better decision-making performance than 3-year-olds. This effect was independent of developmental changes in inductive reasoning, language, and working memory. There were also sex differences in decision-making performance, which were apparent only in 3-year-old children and favored girls. Moreover, age predicted awareness of task and the correlation between the latter and decision-making performance was significant, but only in 4-year-old children. This study thus indicates that there is a remarkable developmental leap in affective decision making, whose effects are apparent around the age of 4, which according to our results, also marks the age when the correlation of declarative knowledge and decision-making performance becomes significant. 相似文献

Most right-handed crossed aphasics are not apractic. They usually have agraphia characterized by misspellings but retain the ability to write well-formed graphemes. We describe a right-handed patient with a right parietal lesion who was aphasic and not apractic. He was unable to write any formed graphemes despite a relatively preserved ability to spell aloud. We postulate that praxis and writing are dissociated in this patient because the motor engrams for praxis were located in his left hemisphere and the engrams for writing were in his right hemisphere. In addition, he comprehended commands for limb motor activities (praxis) far better than he comprehended other speech. This suggests that in this patient the areas used to comprehend limb motor commands may be anatomically distinct from areas important in comprehending other aspects of speech. 相似文献

This study was designed to investigate the conditions under which the negative consequences of social influence attempts can be mitigated by freedom-affirming interventions. Eighty-eight high school girls received an influence message, presumably written by a co-worker, containing either a threat or a promise. In addition, subjects were or were not given a choice option as to mode of compliance, if they chose to comply with the message. In half the cases, the Interpersonal condition, subjects received their choice/no choice option from their co-worker; in the other half of the cases, the Noninterpersonal condition, subjects were assigned the choice/no choice option by a random event unknown to the influencing agent. As anticipated, in the Interpersonal as compared to the Noninterpersonal condition, (a) threats produced greater compliance when a choice was offered than when it was not, and (b) promises and threats were more equivalent in gaining compliance when a choice was offered than when it was not. These results, which suggest that in a social setting individuals' concerns about freedom are interpersonally motivated, are discussed in terms of their relation to and implications for reactance theory. 相似文献

It has been suggested that the repetition defect seen in conduction aphasia is caused by an auditory immediate memory defect. The purposes of this study were the following: to ascertain whether the finding of an auditory immediate memory defect in conduction aphasia could be replicated, to ascertain whether Broca's aphasics have a similar type of immediate memory defect, and to ascertain whether a relationship exists between immediate memory and comprehension of spoken language. Digits were either spoken or presented visually to Broca's and conduction aphasics. An analysis of span scores reveals that within each group there were no significant differences between the modes of presentation or the response modes. There were no significant differences between the aphasic groups. Comprehension of spoken language significantly correlated with digit span scores. 相似文献

In this paper we describe the performance of an amnesic with a left retrosplenial lesion on three memory tasks assessing his ability to judge when a previously learned event had occurred. This patient was dramatically impaired in acquiring temporal information about new stimuli, and this defect could not be attributed to recognition failures or to frontal lobe dysfunction. In contrast to his impaired acquisition of temporal information, he had no difficulty judging the temporal order of remote historical events. The pattern of performance displayed by this patient suggests a specific defect in "time-tagging" of new incoming information. 相似文献

Letter imagery deficits in a case of pure apraxic agraphia 总被引:4,自引:0,他引:4
Pure apraxic agraphia is a condition in which motor writing is impaired but limb praxis and nonmotor writing (typing, anagram letters) are preserved. This condition is believed to result from disruption of a parietal lobe graphemic area which generates grapheme representations used to program motor-writing patterns. We report a single case of pure apraxic agraphia in which defective letter imagery was evident. Results of writing and imagery evaluations suggest that the graphemic area may be responsible for generating letter images. In this respect, clinical evaluation of letter imagery abilities in cases of apraxic agraphia may be useful in identifying subtypes of the disorder resulting in a better understanding of the neuropsychological process involved in writing. 相似文献

The background page on which a stimulus is presented can influence the allocation of attention to that stimulus. The purpose of this study was to learn if there are hemispheric asymmetries in how background distraction affects attentional processing. Asymmetries were investigated by having right eye dominant subjects perform line bisections and manipulating the side of background distraction (right versus left), the eye of regard (right versus left), and the type of attention allocated (focal versus global). Overall subjects bisected lines to the left of center (pseudoneglect) and when viewing with the right eye (versus left) deviated more to the left. Subjects had more background distraction when viewing symbol than solid lines. Although overall, bias did not differ with the side of background distraction or the line being on one side or the other, when subjects viewed symbol, but not solid lines, this leftward bias was increased when the line was displaced to the right, thereby increasing the size of the left sided background. These findings suggest that when engaging the left hemisphere by using focused attention and placing the line on the right side, there is more distraction than when the right hemisphere is engaged. 相似文献

This research examines how the method of selecting women leaders affects other women's leadership interest. The results of three experiments (N = 1,015) indicated that only when women leaders were selected due to merit, not quota-based policies, did they boost female participants’ interest in a leadership position. These reactions were mediated by perceptions of the woman leader's deservingness of her position (Studies 1–3) and consequent acceptance as a role model (Studies 2 and 3). Accordingly, success information validating quota-based selected leaders’ competence provided a boost in leadership interest equal to that of merit-based selected leaders (Study 2). For male participants, quota but not merit-based selected women leaders lowered interest in leadership due to their pessimistic assessment of the probability of being selected (Study 1). These results suggest that a wise implementation of quota regulations includes validating women's competence so they are perceived as deserving of their leader roles and can thus serve as inspiring role models. 相似文献

We tested the hypothesis that the right hemisphere is dominant for motor activation of "intention." If the right hemisphere is dominant for intention and if intention is a prerequisite for movement, motor impairment should be worse after an infarct in the right hemisphere than in the left. We asked nine subjects with right and nine with left hemisphere infarcts to elevate each shoulder independently. Subjects with right hemisphere lesions had more trouble moving the contralateral shoulder. The data are consistent with the hypothesis that the right hemisphere is dominant for motor activation or intention. 相似文献
