Many people rely on academic performance as an important part of their self-concept, or have academic contingencies of self-worth. We compared academic contingencies of self-worth in three groups of participants, who varied in their feelings about two minority identities: sexual minority Asian/Pacific Islanders, straight Asian/Pacific Islanders, and sexual minority Whites. Comparing pairs of groups that shared one marginalized social identity, we confirmed our hypothesis that participants’ feelings about their racial identity related to contingent self-worth differently based on their sexuality; in contrast, participants’ feelings about their sexual identity related to contingent self-worth in the same way regardless of race. The group defined by the intersection of two minority social identities (Asian/Pacific Islander and sexual minority) is of particular interest. 相似文献

Systematic investigations indicate that some of the recognized psychiatric disorders can be identified among those with mental retardation due to chromosomal abnormalities. We report a psychotic patient with mild mental retardation (intelligence quotient: 68) and minor anomalies that had a chromosomal aberration not previously described in a psychotic patient. Our patient highlights the importance of the cytogenetic study in psychiatric patients with comorbid mental retardation or minor anomalies. In addition, her psychosis symptoms may be helpful to propose a new candidate gene for psychosis. 相似文献

The facial expressions of fear and anger are universal social signals in humans. Both expressions have been frequently presumed to signify threat to perceivers and therefore are often used in studies investigating responses to threatening stimuli. Here the authors show that the anger expression facilitates avoidance-related behavior in participants, which supports the notion of this expression being a threatening stimulus. The fear expression, on the other hand, facilitates approach behaviors in perceivers. This contradicts the notion of the fear expression as predominantly threatening or aversive and suggests it may represent an affiliative stimulus. Although the fear expression may signal that a threat is present in the environment, the effect of the expression on conspecifics may be in part to elicit approach. 相似文献

"Economic man" in cross-cultural perspective: behavioral experiments in 15 small-scale societies 总被引:1,自引:0,他引:1

Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model - based on self-interest - fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life. 相似文献

Object naming studies have generally observed that both normal and brain damaged individuals are faster and more accurate at identifying non-living objects than living objects (). However, a potential confounding variable, manipulability, has been present in past studies that may mediate this effect. Previous studies that have observed a non-living advantage have often used manipulable and non-manipulable exemplars to represent the non-living and living groups, respectively. Under conditions which controlled for object manipulability and familiarity, results demonstrated advantages for the identification of non-manipulable and for living objects. 相似文献

Food-storing birds, black-capped chickadees (Poecile atricapilla), and nonstoring birds, dark-eyed juncos (Junco hyemalis), matched color or location on a touch screen. Both species showed a divided attention effect for color but not for location (Experiment 1). Chickadees performed better on location than on color with retention intervals up to 40 s, but juncos did not (Experiment 2). Increasing sample-distractor distance improved performance similarly in both species. Multidimensional scaling revealed that both use a Euclidean metric of spatial similarity (Experiment 3). When choosing between the location and color of a remembered item, food storers choose location more than do nonstorers. These results explain this effect by differences in memory for location relative to color, not division of attention or spatial discrimination ability. 相似文献

The model of apraxia proposed by Roy (1996) states that three patterns of apraxia should be observed across pantomime and imitation conditions. In the present analysis the frequency and severity of each pattern of apraxia were examined in a consecutive sample of left-(LHD) and right-hemisphere-damaged (RHD) patients during the production of intransitive limb gestures. The results indicated that a significant proportion of LHD and RHD patients were selectively impaired in formulating the ideational component of intransitive limb gestures. 相似文献

Twenty-nine right-handed participants made unimanual movements to 5 target locations while standing and while balancing on a rocker platform. Manual preference was affected by target location (p < .001; manual preference tended to be concordant with target hemispace) and posture (p < .05; responses from the rocker platform were associated with a lower level of right-hand responding). A location by posture interaction (p < .05) indicated that the effect of posture was present only for targets in left hemispace; the right hand was used less frequently in the rocker condition than simple standing. Manual preference is viewed as a process of response selection motivated by an effort to minimize neural processing and mechanical costs. 相似文献

Given the importance of individual differences in the study of applicant attraction to organizations, we conducted a meta-analysis to assess the relationship between both applicant deep-level characteristics (e.g., applicant ability, personality, and experience) and surface-level characteristics (e.g., race, gender, and age) with applicant attraction. Results of our review of over 1700 articles (of which, 85 provided relevant data for our analysis) indicated that several relevant applicant individual differences are related to applicant attraction, independent of organizational influences. Stronger effect sizes were found for applicant deep-level characteristics (versus surface level) as well as field studies (versus lab studies). Extraversion and conscientiousness had the strongest positive relationships with applicant attraction, while applicant grade point average, as an indicator of ability, had the strongest negative relationship. The significance of these findings, including implications for applicants and organizations, is discussed. 相似文献

Four experiments are reported on the importance of retrospective judgments of performance (postdictions) on tests. Participants answered general knowledge questions and estimated how many questions they answered correctly. They gave higher postdictions when easy questions preceded difficult questions. This was true when time to answer each question was equalized and constrained, when participants were instructed not to write answers, and when questions were presented in a multiple-choice format. Results are consistent with the notion that first impressions predominate in overall perception of test difficulty. 相似文献
