Heterosexual dating partner preferences were examined in a multi-ethnic context. Four groups at UCLA were studied: Asian Americans, African Americans, Latino Americans, and Euro Americans. Participants completed surveys asking them to rate a ‘typical/hypothetical’ opposite-sex member for each of the four ethnic groups on physical attractiveness, similarity, social network approval, status, and desirability as a dating/marriage partner; social identification with the ethnic ingroup was also assessed. Members of all four ethnic groups demonstrated some degree of ethnocentrism on most measures (especially partner preferences) by rating opposite-sex members of their own group higher than outgroup members rated them; however, Asians and Latinos rated opposite-sex Whites as more physically attractive than typical members of their own group, and Latinos and Blacks rated Whites and Asians as higher status. Overall, Whites received more favourable ratings than any of the three minority groups. Regression analyses indicated that social network approval (by far), similarity, and physical attractiveness were (in that order) the most powerful predictors of ethnocentrism in partner preferences. Avenues of integration and interpretation between theories of inter-personal attraction and intergroup relations were considered, including the dimensionality of ingroup favouritism, and the need for stronger consideration of social influence in theories of intergroup relations. 相似文献

Neural Network models are commonly used for cluster analysis in engineering, computational neuroscience, and the biological sciences, although they are rarely used in the social sciences. In this study we compare the classification capabilities of the 1-dimensional Kohonen neural network with two partitioning (Hartigan and Späthk-means) and three hierarchical (Ward's, complete linkage, and average linkage) cluster methods in 2,580 data sets with known cluster structure. Overall, the performance of the Kohonen networks was similar to, or better than, the performance of the other methods. 相似文献

AIDS/HIV has been described as one of the most pressing medical and social problems of this century. A review of the psychosocial and counselling literature relating to it indicates that the predominant psychotherapeutic approach with clients is symptom-focused and presents psychological problems as being inevitable in the course of illness. A systems approach is considered to have a good fit' with HIV-related problems because of issues relating to unpredictability, relationships, interaction, complexity and secrecy which arise in the course of the illness and its management. Some of the counselling tasks of an AIDS counsellor are set out. Consideration of these can help the system (client, family, health care team, counsellor) both to define problems and to find solutions to them without resorting to prior assumptions about either. 相似文献

By most theories of lexical access, idiosyncratic aspects of speech (such as voice details) are considered noise and are filtered in perception. However, episodic theories suggest that perceptual details are stored in memory and mediate later perception. By this view, perception and memory are intimately linked. The present investigation tested this hypothesis by creating symmetric illusions, using words and voices. In two experiments, listeners gave reduced noise estimates to previously heard words, but only when the original voices were preserved. Conversely, in two recognition memory experiments, listeners gave increased old responses to words (or voices) presented in relatively soft background noise. The data suggest that memory can be mistaken for perceptual fluency, and perceptual fluency can be mistaken for memory. The data also underscore the role of detailed episodes in lexical access. 相似文献

Allocentric spatial memory was studied in dogs of varying ages and sources using a landmark discrimination task. The primary goal of this study was to develop a protocol to test landmark discrimination learning in the dog. Using a modified version of a landmark test developed for use in monkeys, we successfully trained dogs to make a spatial discrimination on the basis of the position of a visual landmark relative to two identical discriminanda. Task performance decreased, however, as the distance between the landmark and the “discriminandum” was increased. A subgroup of these dogs was also tested on a delayed nonmatching to position spatial memory task (DNMP), which relies on egocentric spatial cues. These findings suggest that dogs can acquire both allocentric and egocentric spatial tasks. These data provide a useful tool for evaluating the ability of canines to use allocentric cues in spatial learning. 相似文献

Self-evaluations of body image were examined in a 2 (attractiveness of stimulus person) × 2 (sex of stimulus person) design to determine if contrast effects consistent with evolutionary psychology occur for women's self-perceptions of their body image. Main effects for attractiveness were hypothesized. Higher self-ratings for figure-related aspects of body image were predicted for women exposed to an unattractive male or female. These effects were significant. Women exposed to an unnattractive male or female had more positive feelings about figure-related aspects of their body image than women exposed to an attractive male or female. Contrast effects in accordance with evolutionary theory occur for aspects of body image that play a role in inferences regarding reproductive fitness. 相似文献

The purpose of this investigation was to examine the extent to which racial identity attitudes mediate the relationship between
gender role conflict and psychological symptoms in Men of Color. The mediating role of racial identity was tested in Study
1 with a sample of Black men and in Study 2 with a sample of Asian and Latino men. The results of Study 1 provided support
for full mediation, whereas in Study 2 evidence was found for partial mediation. The combination of the studies' findings
underscores the importance of considering the extent to which Men of Color identify with their own racial group when examining
the relationship between gender role conflict and psychological symptoms. 相似文献
