A 5-study investigation of reactions of dominant group members (i.e., White Americans) to diversity (relative to racial minority reactions) provides evidence of implicit and explicit associations between multiculturalism and exclusion and of a relationship between perceived exclusion and reactions to diversity. In Study 1, Whites but not racial minorities were faster in an implicit association task at pairing multiculturalism with exclusion than with inclusion. This association diminished in Study 2 through a subtle framing of diversity efforts as targeted toward all groups, including European Americans. In Study 3, in a "Me/Not Me" task, Whites were less likely than minorities to pair multiculturalism concepts with the self and were slower in responding to multiculturalism concepts. Furthermore, associating multiculturalism with the self (Study 3) or feeling included in organizational diversity (Study 4) predicted Whites' endorsement of diversity and also accounted for the oft-cited group status difference in support for diversity initiatives. Study 5 showed that individual differences in need to belong moderated Whites' interest in working for organizations that espouse a multicultural versus a color-blind approach to diversity, with individuals higher in need to belong less attracted to organizations with a multicultural approach. Overall, results show that the purportedly "inclusive" ideology of multiculturalism is not perceived as such by Whites. This may, in part, account for their lower support for diversity efforts in education and work settings.  相似文献

The present study investigated whether facial expressions of emotion presented outside consciousness awareness will elicit evaluative responses as assessed in affective priming. Participants were asked to evaluate pleasant and unpleasant target words that were preceded by masked or unmasked schematic (Experiment 1) or photographic faces (Experiments 1 and 2) with happy or angry expressions. They were either required to perform the target evaluation only or to perform the target evaluation and to name the emotion expressed by the face prime. Prime-target interval was 300 ms in Experiment 1 and 80 ms in Experiment 2. Naming performance confirmed the effectiveness of the masking procedure. Affective priming was evident after unmasked primes in tasks that required naming of the facial expressions for schematic and photographic faces and after unmasked primes in tasks that did not require naming for photographic faces. No affective priming was found after masked primes. The present study failed to provide evidence for affective priming with masked face primes, however, it indicates that voluntary attention to the primes enhances affective priming.  相似文献

Being able to use information communication technology (ICT) effectively has become an essential element of participation within an increasingly digital culture. However, there are differences in participation within this digital culture. Prenatal testosterone exposure is thought to influence the development of numeric capabilities and relate to levels of anxiety, both of which contribute towards engagement with ICT. This study examined whether an index of prenatal exposure to testosterone, digit ratio (2D:4D), is related to successful involvement within a computer-technology context - performance in a Java programming course. Three studies (N = 73,75,65) identified a consistent negative correlation between 2D:4D digit ratio and attainment (r ≈ −0.2). A fourth study (N = 119) found that 2D:4D digit ratio positively correlated with two indices of computer-related anxieties, as well as anxiety sensitivity (r = 0.32/0.51). These results suggest that males and females who have been exposed to higher levels of testosterone within the womb perform better upon academic assessments of Java-related programming ability within computer science education, and have lower levels of computer-related anxieties outside computer science education. Thus, the 2D:4D index of prenatal testosterone exposure correlated with the two factors that directly impact upon ICT engagement, which is increasingly essential to effectively participate within educational and occupational environments.  相似文献

Congenital amusia manifests as a lifelong difficulty in making sense of musical sound. The extent to which this disorder is accompanied by deficits in visuo-spatial processing is an important question, bearing on the issue of whether pitch processing draws on supramodal spatial representations. The present study assessed different aspects of visuo-spatial processing with a range of tasks (Shepard-Metzler Mental Rotation, Corsi Blocks Task, Visual Patterns Test) in 14 amusics and matched controls. The absence of a group difference on any of these tasks fails to support a previous claim that the disorder is strongly related to deficits in spatial processing. However, a subgroup of amusics, with significantly elevated thresholds on a pitch direction discrimination task relative to the rest of the group, were slower, but equally accurate, at Mental Rotation. This finding is discussed in relation to the nature of supramodal representations of contour and strategies for dynamic mental transformation.  相似文献

Background  

Social and structural inequities shape health and illness; they are an everyday presence within the doctor-patient encounter yet, there is limited ethical guidance on what individual physicians should do. This paper draws on a study that explored how doctors and their professional associations ought to respond to the issue of social health inequities.  相似文献

We assessed lay perceptions of the causes of and solutions to ethnic prejudice, and determined whether individual differences related to intergroup relations (social dominance orientation, right‐wing authoritarianism) and to cognitive style (personal need for structure, need for cognition) were predictive of these perceptions. Results revealed clear and coherent lay beliefs about the causes of and solutions to ethnic prejudice, and significant relations between perceived causes and solutions. Systematic relations between the intergroup‐relevant individual differences and these perceptions also emerged, in ways that may serve to justify and legitimize ethnic bias. Implications for the justification and maintenance of ethnic bias and for intervention programmes are discussed. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

Logistic Approximation to the Normal: The KL Rationale   总被引:1,自引:0,他引:1  
A rationale is proposed for approximating the normal distribution with a logistic distribution using a scaling constant based on minimizing the Kullback–Leibler (KL) information, that is, the expected amount of information available in a sample to distinguish between two competing distributions using a likelihood ratio (LR) test, assuming one of them is true. The new constant 1.749, computed assuming the normal distribution is true, yields an approximation that is an improvement in fit of the tails of the distribution as compared to the minimax constant of 1.702, widely used in item response theory (IRT). The minimax constant is by definition marginally better in its overall maximal error. It is argued that the KL constant is more statistically appropriate for use in IRT. The author would like to thank Sebastian Schreiber for his generous assistance with this project.  相似文献

Background/ObjectiveThe comorbidity of depression and fibromyalgia chronic syndrome has been well documented in the literature; however, the cognitive structure of these patients has not been assessed. Previous results reported variability in cognitive rigidity in depressive patients, the key for this might be the presence of chronic physical pain such as fibromyalgia. The present study explores and compares the cognitive rigidity and differentiation, between patients with depression with and without fibromyalgia syndrome.MethodThirty one patients with depression and fibromyalgia were matched, considering age, sex and number of depressive episodes, with 31 patients with depression but without fibromyalgia diagnosis. Cognitive rigidity and differentiation were measured with the repertory grid technique.ResultsThe results indicated that depressed patients with fibromyalgia presented higher levels of depressive symptoms, greater cognitive rigidity and lower cognitive differentiation than those without fibromyalgia.ConclusionsThe results might inform future treatments to address the cognitive structure of these patients.  相似文献
