Understanding the perception of multiracial persons is increasingly important in today's diverse society. The present research investigated the process of categorizing multiracial persons as “Multiracial.” We hypothesized that perceivers would make fewer Multiracial categorizations of multiracials and that these categorizations would take longer than monoracial categorizations. We found support for these hypotheses across six experiments. Experiment 1 demonstrated that perceivers did not categorize morphed Black–White faces as Multiracial with the same frequency with which they categorized Black and White faces as Black and White (respectively), and that categorizations of multiracials as Multiracial took longer than monoracial categorizations. Experiment 2 replicated and extended these effects to real Black–White faces. Experiment 3 showed that these findings generalized to Asian–White faces. We used pixel variance analysis to show that these effects were not due to increased variance among Multiracial faces. The image analysis showed that the Black–White morphs and real biracials were actually less varied than either the Black or White sets of faces. Experiments 4 and 5 demonstrated that cognitive load and time constraints detrimentally affected multiracial, but not monoracial, categorizations. Experiment 6 showed that imbuing monoracial categories with importance decreases the use of the Multiracial category. Implications of these findings for understanding perceptions of multiracial persons are discussed. 相似文献

Incremental validity of person-organization fit over the Big Five personality measures 总被引:1,自引:0,他引:1
Few studies have provided the validity evidence of a measure of objective person-organization fit (P-O fit) as a selection tool. The present study used a concurrent validation design to examine the criterion-related validity and the incremental validity of a P-O fit measure beyond the validity of the Big Five personality test for predicting job performance (task performance and organizational citizenship behavior) and employee commitment (organizational commitment and supervisory commitment) for a group of high-tech professional employees in Taiwan. Results showed that P-O fit predicted the contextual component of overall job performance and was significantly related to two types of employee commitment. Moreover, P-O fit had an incremental validity beyond that of the personality measures for predicting some of our outcome variables. 相似文献

A hypothesis was examined, that gelotophobia (the fear of being laughed at) was negatively related to Type I thinking styles and positively related to Type II thinking styles as defined in Sternberg's theory of mental self-government. 431 university students (250 women, 181 men; M age = 20.4 yr., SD = 1.2) completed self-report measures of gelotophobia (GELOPH <15>) and thinking styles (Thinking Styles Inventory-Revised). Correlation and regression analyses were conducted. The results indicated that gelotophobia was negatively and significantly related to four Type I thinking styles (legislative, judicial, liberal, and hierarchical thinking styles) and a Type III thinking style (external), while it was positively and significantly related to a Type II thinking style (conservative). Thinking styles uniquely explained 18% of the total variance in gelotophobia scores. Possible interventions from the perspective of thinking styles in the treatment of gelotophobia were discussed. 相似文献

The aims of this paper are two‐fold: (i) to examine the impact of audience individualism and collectivism orientation on the judgment of strategic self‐presentations and (ii) to test whether audience individualism and collectivism orientation would affect the importance of likeability and competence in determining social outcomes. In two studies, participants evaluated modest and boastful presentations in an achievement context. It was found that the more collectivistic the audience was, the more likely the modest presenter was to be rated as likable, competent, and deserving of a desirable social outcome. In contrast, the more individualistic the audience was, the more likely the boastful presenter was to be rated as likeable, competent, and deserving of a desirable social outcome. The importance of likeability and competence in predicting the final social outcome was moderated by audience individualism and collectivism orientation. Likeability was more important in deciding the social outcome for those who were more collectivistic than for those who were less so (Study 1). Competence was more important in determining the social outcome for those who were more individualistic (Study 2). These studies build a potential theoretical bridge between social influence and social perception/social judgment literature. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Driving on a busy road, eluding a group of predators, or playing a team sport involves keeping track of multiple moving objects. In typical laboratory tasks, the number of visual targets that humans can track is about four. Three types of theories have been advanced to explain this limit. The fixed-limit theory posits a set number of attentional pointers available to follow objects. Spatial interference theory proposes that when targets are near each other, their attentional spotlights mutually interfere. Resource theory asserts that a limited resource is divided among targets, and performance reflects the amount available per target. Utilising widely separated objects to avoid spatial interference, the present experiments validated the predictions of resource theory. The fastest target speed at which two targets could be tracked was much slower than the fastest speed at which one target could be tracked. This speed limit for tracking two targets was approximately that predicted if at high speeds, only a single target could be tracked. This result cannot be accommodated by the fixed-limit or interference theories. Evidently a fast target, if it moves fast enough, can exhaust attentional resources. 相似文献

This study examined relations of achievement goals of writers who are speakers of English as a foreign language (EFL), the frequency of their writing strategy use, and the quality of their writing from a multiple goals perspective. The goal profiles of 57 EFL college students with similar writing proficiency were based on rating items of an unpublished scale; Group 1 had strong mastery and strong performance-approach goals, and two groups included students with only one strong mastery (Group 2) or performance (Group 3) goal. Think-aloud protocols indicated that the participants adopted 21 strategies in an argumentative writing task, classified into five categories. Group 1 was found to use writing strategies of monitoring or evaluating, revising, and compensating significantly more often than the other two groups, and produced better essays. Strong mastery and performance-approach goals might be beneficial for EFL college writers. 相似文献

When making choices between risky options, human decision-makers exhibit a number of framing effects. One of the most prominent framing effects is the tendency for decision makers to evaluate gambles relative to a reference point, and to act risk-seeking when prospects are framed as losses but risk-averse when identical prospects are framed as gains. This tendency for risk-preferences to reverse between loss and gain frames has been termed the reflection effect, and is one of the primary predictions of Prospect Theory. Here, we explore whether non-human primates exhibit a similar reflection effect. Using a token-trading task, we show that capuchin monkeys (Cebus apella) exhibit an analogous reversal of risk preferences depending on whether outcomes are presented as gains or losses, suggesting that similar framing effects also influence choice in non-human primates. This finding suggests that the mechanisms that drive framing effects in humans may be evolutionarily ancient, extending broadly across the primate order. 相似文献

The objective of this study investigated cognitive impairments and their correlations with fractional anisotropy (FA) and mean diffusivity (MD) in patients with neuromyelitis optica (NMO) without visible lesions on conventional brain MRI during acute relapse. Twenty one patients with NMO and 21 normal control subjects received several cognitive tests to assess cognitive function. Head diffusion tensor imaging (DTI) of all patients with NMO were collected with a 3-T MR system. Correlations of cognitive test scores and whole brain FA and MD were examined by voxel-based analysis. Region-of-interest analysis was applied to the significantly correlated regions which the most frequently appeared. We found that NMO patients without visible brain lesions had significantly impaired learning and memory, decreased information processing speed, and damaged attention compared with normal control subjects. These impaired cognitive domains were significantly correlated with FA and MD in local regions of corpus callosum, anterior cingulate and medial frontal cortex. In corpus callosum of NMO patients, mean FA was significantly lower and mean MD higher than normal control subjects. Our findings suggest that cognitive impairments in learning and memory, information processing speed and attention occur in NMO patients without visible brain lesions during acute relapse. The impairments in immediate and short-term memory in NMO patients may be due to information encoding deficits in the process of information acquisition. The corpus callosum of such patients may have local microscopic damages that play a role in cognitive impairments during acute relapse. 相似文献
