Ethnic and American identity, as well as positivity and negativity toward multiple social groups, were assessed in 392 children attending 2nd or 4th grade in various New York City neighborhoods. Children from 5 ethnic groups were recruited, including White and Black Americans, as well as recent immigrants from China, the Dominican Republic, and the former Soviet Union. For ethnic minority children, greater positivity bias (evaluating one's ingroup more positively than outgroups) was predicted by immigrant status and ethnic identity, whereas negativity bias (evaluating outgroups more negatively than one's ingroup) was associated with increased age, immigrant status, and (among 4th graders only) ethnic identity. In addition, a more central American identity was associated with less intergroup bias among ethnic minority children. 相似文献

Biases in visual orienting to negative and positive scenes in dysphoria: An eye movement study 总被引:1,自引:0,他引:1
The study investigated biases for negative information in component processes of visual attention (initial shift vs. maintenance of gaze) in dysphoric and nondysphoric individuals. Eye movements were recorded while participants viewed a series of picture pairs depicting negative, positive, and neutral scenes (each pair presented for 3 s). Biases in initial orienting were assessed from the direction and latency of the initial shift in gaze, whereas biases in the maintenance of attention were assessed from the duration of gaze on the picture that was initially fixated. Results indicated that the dysphoric group showed a significantly greater bias to maintain gaze longer on negative pictures, relative to control pictures, compared with the nondysphoric group. There was no evidence of a dysphoria-related bias in initial shift of orienting to negative cues. Results are consistent with a depression-related bias that operates in the maintenance of attention on negative material. 相似文献

The authors assessed the degree to which schizotypal characteristics in a nonclinical population were associated with impairments in the ability to correctly identify emotions as expressed in facial, paralinguistic, and postural cues. Participants completed the Schizotypal Personality Questionnaire (SPQ; A. Raine, 2005), and the 3 receptive subtests of the Diagnostic Analysis of Nonverbal Accuracy-2 (DANVA2; S. Nowicki Jr., 2005). The SPQ subscales No close friends and Suspiciousness were correlated with impaired ability to correctly identify postural affective cues on the DANVA2. Unusual perceptual experiences were correlated with deficits in the ability to identify emotions on the DANVA2 paralinguistic measure. Impairments in the ability to correctly perceive and respond to expressions of affect may be part of a deficit in social cognition that contributes to development of schizotypal traits. 相似文献

Disparities exist between Indigenous Australians and non‐Indigenous Australians on indicators of life expectancy, alcohol and drug use, adult and juvenile incarceration, and rates of hospitalisation for self‐harm, suicide, and mental and behavioural disorders due to psychoactive substance use. Psychology is a discipline that can assist in remedying these issues, yet disparities are evident in Indigenous participation in higher education generally, as well as within tertiary psychology education specifically. Ten Indigenous Australian psychologists were interviewed to investigate possible barriers and enablers for Indigenous students studying psychology at university. Hermeneutic phenomenology guided the research and its analysis, whereby the data went through a process known as the “hermeneutic circle”; data were analysed in itself, as well as part of the whole, leading to the world views of the participant and researcher converging into a “horizon of meaning.” Sources of support for Indigenous students included family support, financial assistance, and Indigenous student support centres. Potential barriers to university study of psychology were negative conceptions of higher education and psychology by the Indigenous community, “culture shock” upon relocating to the metropolitan area, a lack of Indigenous content and staff, and culturally insensitivity by staff members. Efforts should be made to address these barriers to participation, as well as to support those structures and services that were supportive for students. 相似文献

The present research tested a prejudice‐reduction intervention based on imagined contact. White children imagined interacting with a child from an ethnic out‐group (Asian) once a week for 3 weeks, or did not take part in this activity (control group). Compared with the control group, children who engaged in imagined contact subsequently showed more positive attitudes, greater perceived similarity, and willingness for intergroup contact. The effect of the intervention on willingness for contact was mediated by positive attitude change. Implications for imagined‐contact theory and the development of prejudice‐reduction techniques for schools are discussed. 相似文献

Evidence-based medicine (EBM) makes use of explicit procedures for grading evidence for causal claims. Normally, these procedures categorise evidence of correlation produced by statistical trials as better evidence for a causal claim than evidence of mechanisms produced by other methods. We argue, in contrast, that evidence of mechanisms needs to be viewed as complementary to, rather than inferior to, evidence of correlation. In this paper we first set out the case for treating evidence of mechanisms alongside evidence of correlation in explicit protocols for evaluating evidence. Next we provide case studies which exemplify the ways in which evidence of mechanisms complements evidence of correlation in practice. Finally, we put forward some general considerations as to how the two sorts of evidence can be more closely integrated by EBM. 相似文献

Impairments in cognitive control are a defining feature of schizophrenia. Aspects of cognitive control include proactive control—the maintenance of task rules or goals to bias attention and maintain preparedness—and reactive control—the engagement of attention in reaction to changing cognitive demands. Proactive control is thought to be particularly impaired in schizophrenia. We sought to examine proactive and reactive control in schizophrenia, as measured by reaction time (RT) variability, and especially long RTs, which are thought to represent lapses in proactive control, during the Stroop paradigm. Furthermore, we sought to examine the neural underpinnings of lapses in proactive control and the subsequent engagement of reactive control in those with schizophrenia, as compared to healthy controls, using fMRI. We found that patients with schizophrenia displayed greater RT variability and more extremely long RTs than controls suggesting that proactive control was weaker in the schizophrenia than in the control group. All of the subjects engaged regions of the cognitive control network during long RTs, consistent with an engagement of reactive control following a failure in proactive control on these trials. The schizophrenia group, however, displayed significantly diminished activity in these regions relative to controls. Our results suggest increased failures in proactive control, but also impaired reactive control, in schizophrenia as compared to healthy subjects. 相似文献

In location-based tasks, responses related to (prime trial) distractor-occupied locations automatically undergo activation, followed by inhibition, which causes these responses to become execution-resistant (ER). Distractor-response ER takes time to override, delaying target reactions that later require this response (e.g., probe, ignored-repetition trials), causing the spatial negative priming (SNP) phenomenon. We learned in this study that distractor-response ER affords this output a degree of error protection. Specifically, when the probe target appeared at a new location, former (prime) distractor responses were used erroneously significantly less often than their control response counterparts, likely due to their ER feature, which discourages their inappropriate selection (i.e., “ER” provides error protection). This error protection also was evident when a previous distractor response was activated by a distractor on the probe (i.e., distractor-repeat trial). Notably, error protection remained effective over extensive practice, as did SNP size (i.e., ER override time) after an initial decline. 相似文献
