Past quantitative ethnic identity research on transracial and international adoptees (TRIAs) has focused on their birth culture. Given that adoptees may also identify with their adoptive family’s culture, we examined Korean and White European American ethnic identities in Korean American adoptees. Identity exploration and commitment were significantly positively correlated within each referent group. Results also indicated relatively higher levels of birth group identity exploration and higher adoptive group identity commitment. In addition, we used cluster analysis to create ethnic identity profiles and investigated the relations between identity profiles and sense of belonging and exclusion. Our findings signal a need to support TRIAs to develop inclusive flexible ethnic identities and suggest future research should examine multiple referent groups and the intersection of these identities. 相似文献

Metabotropic glutamate receptor 5 (mGlu5) has been implicated in a variety of learning processes and is important for inhibitory avoidance and conditioned taste aversion learning. MGlu5 receptors are physically connected with NMDA receptors and they interact with, and modulate, the function of one another in several brain regions. The present studies used systemic co-administration of an mGlu5 receptor positive allosteric modulator, 3-cyano-N-(1,3-diphenyl-1H-pyrazol-5-yl)benzamide (CDPPB) and an NMDA receptor antagonist dizocilpine maleate (MK-801) to characterize the interactions of these receptors in two aversive learning tasks. Male Sprague-Dawley rats were trained in a single-trial step-down inhibitory avoidance or conditioned taste aversion task. CDPPB (3 or 10mg/kg, s.c.), delivered by itself prior to the conditioning trial, did not have any effect on performance in either task 48 h after training. However, CDPPB (at 3mg/kg) attenuated the MK-801 (0.2mg/kg, i.p.) induced learning deficit in both tasks. CDPPB also reduced MK-801-induced hyperactivity. These results underlie the importance of mGlu5 and NMDA receptor interactions in modulating memory processing, and are consistent with findings showing the efficacy of positive allosteric modulators of mGlu5 receptors in reversing the negative effects of NMDA receptor antagonists on other behaviors such as stereotypy, sensorimotor gating, or working, spatial and recognition memory. 相似文献

We tested whether adults (experiment 1) and 4 - 5-year-old children (experiment 2) identify the sex of highly attractive faces faster and more accurately than not very attractive faces in a reaction-time task. We also assessed whether facial masculinity/femininity facilitated identification of sex. Results showed that attractiveness facilitated adults' sex classification of both female and male faces and children's sex classification of female, but not male, faces. Moreover, attractiveness affected the speed and accuracy of sex classification independently of masculinity/femininity. High masculinity in male faces, but not high femininity in female faces, also facilitated sex classification for both adults and children. These findings provide important new data on how the facial cues of attractiveness and masculinity/femininity contribute to the task of sex classification and provide evidence for developmental differences in how adults and children use these cues. Additionally, these findings provide support for Langlois and Roggman's (1990 Psychological Science 1 115 121) averageness theory of attractiveness. 相似文献

Patterns of intellectual abilities for Mexican American and Native American Papago children were contrasted with those of White children, independent of overall differences in ability. Large differences in highly verbal skills remained, with Whites consistently outscoring the other two groups. Native Americans showed higher performance than Whites on spatial-visualization tasks but Mexican Americans exceeded Whites on no tasks. These race-related patterns of ability are nearly opposite those found in Black–White comparisons. 相似文献

Eighty-seven parents of children with Down Syndrome (DS; 63 women, 24 men) wrote narratives about finding out that their child had DS and completed questionnaire measures of subjective well-being (SWB) and stress-related growth and completed the Sentence Completion Test as a measure of ego development. Forty-two of these individuals participated in a follow-up 2 years later. Foreshadowing and happy endings in the stories were related to heightened SWB at both time periods. Evidence of accommodative change—actively experiencing a paradigmatic shift—was related to stress-related growth and ego development at both time periods. A high sense of closure and accommodation in the stories was associated with the highest levels of stress-related growth. Implications for research on well-being and personal growth are discussed. 相似文献
