This work examines the hypothesis that stereotypes of groups to which low-power people belong should influence the perceptions and behavior of powerful people only when those stereotypes are both contextually relevant (e.g., women in masculine domains) and provide information of relevance given powerful people's beliefs about the relation between subordinates and goal attainment. Findings across two studies supported predictions. In a masculine domain, when high-power men were attentive to subordinate weaknesses that may produce thwarts to goal attainment, stereotypes of women defined the contextually relevant shortcomings of women, and stereotype-consistent high-power behaviors ensued. In contrast, when powerful men were attentive to subordinate strengths that may enhance goal strivings, stereotypes of women were uninformative (i.e., did not contain information about relevant strengths); female and male employees were responded to and, in turn, performed and reacted similarly. The implications of these findings for theorizing on the relation between power and stereotyping are discussed. 相似文献

Temporal integration of speech prosody is shaped by language experience: an fMRI study 总被引:5,自引:0,他引:5

Differences in hemispheric functions underlying speech perception may be related to the size of temporal integration windows over which prosodic features (e.g., pitch) span in the speech signal. Chinese tone and intonation, both signaled by variations in pitch contours, span over shorter (local) and longer (global) temporal domains, respectively. This cross-linguistic (Chinese and English) study uses functional magnetic resonance imaging to show that pitch contours associated with tones are processed in the left hemisphere by Chinese listeners only, whereas pitch contours associated with intonation are processed predominantly in the right hemisphere. These findings argue against the view that all aspects of speech prosody are lateralized to the right hemisphere, and promote the idea that varying-sized temporal integration windows reflect a neurobiological adaptation to meet the 'prosodic needs' of a particular language. 相似文献

This study tested Annett's right-shift theory on spatial ability with two samples from China. The Vandenberg Mental Rotation Test (MRT), Edinburgh Handedness Inventory, and Family Handedness Questionnaire were administered to 266 high school students and 297 undergraduates. We found very few r++ or r-- among Chinese students. Most Chinese are either moderately right-handed or ambidextrous. Consistent with Casey's finding, we found using different methods to classify handedness leads to different conclusions. However, we did not find the effect of familial handedness that Casey found. Visual strategy is related to success on the MRT but handedness is not. 相似文献

Early life experience affects behavior and brain mechanisms. Handling rats during the first three weeks in life can slow age-related cognitive decline (as measured by a hippocampal-dependent spatial learning task) and reduce age-related hippocampal neuron loss. It is not clear, however, whether this early environmental influence on learning is selective for old age or is more general, affecting cognitive development during infancy and young adulthood as well. We briefly exposed neonatal rats to a novel non-home environment for 3 min daily during the first three weeks of life (as a component of the handling method). We found that this brief early environmental manipulation resulted in enhanced hippocampal-dependent learning immediately after weaning and that this learning enhancement persisted into adulthood. These results suggest that subtle early life events can affect cognitive development in all developmental stages and that changes in neural mechanisms other than neuron number are likely to mediate the learning enhancement at multiple developmental stages. 相似文献

Cultural and ethnic influence on proxemic behavior and invasions of personal space were investigated. 173 Chinese Singaporean undergraduates rated minimum interpersonal distance for perceived male intruders from four ethnic groups in Singapore--Malay, Indian, Chinese, and Caucasian. Rated distance scores ranked from "most distant" Indian Chinese dyads decreasing (in order of minimum distance) through Malay-Chinese. Caucasian-Chinese, and Chinese-Chinese dyads, independent of sex. 相似文献

We present observations on the use of racial and cultural stereotypes in psychoanalytic psychotherapy with patients from the majority culture and with those from minority backgrounds. Earlier work has centered on black/white patient dyads and has not taken other possible combinations into account. "Race" and "culture" have sometimes been used synonymously. Our clinical experience indicates that there is some overlap in the themes of transferences to us as members of different racial minorities. We note, however, that for the African-American therapist, projections are more often based on racial stereotypes, whereas for the Chinese-American therapist, projections are based more on cultural assumptions. When careful attention is paid to the manifestations of racial and cultural stereotyping, much can be learned about the patient's inner life, to the benefit of the analytic work. 相似文献
