An X Windows software tool for the construction of faces with a weighted combination of eigenvectors is described. The eigenvectors were extracted from an autoassociative matrix that comprised 100 face images. The program input consists of eigenvectors and sets of weights that describe individual faces and combines these to create face images. The tool creates a panel of buttons that permits the display of individual eigenvectors and the display of an average face as well. Facilities for on-line changes to the intensity of individual eigenvectors can be used to change the appearance of a face. Previously, O’Toole, Abdi, Deffenbacher, and Bartlett (1991) have shown that the intensity of certain individual eigenvectors contains reliable information for determining the sex and race of the face. 相似文献

A proximal-distal theoretical framework was developed to examine the multivariate roots of homophobia. Using data from a sample of 288 undergraduates who had participated in a computer-assisted panel study over a three-year period, the effects on homophobia of distal and proximal family factors (e. g., parental education and family environment), distal and proximal individual factors (e. g., personality constructs and current beliefs), and proximal individual-situational factors (e. g., acquaintance with homosexuals) were tested in regression analyses. Both analyses employing sets of variables varying in proximity to the homophobic attitude and hierarchical regression employing variables contributing significantly in each set supported the proposed framework. All sets predicted significantly when regressed separately on homophobia; the sets containing the distal factors contributed most weakly, and the sets containing the proximal factors contributed most strongly. In hierarchical regression analysis, this pattern maintained such that the incremental increase in r2 decreased with the addition of each more distal set, with the most distal factors failing to contribute significantly to the prediction. The importance of study findings for attitude change efforts is discussed. 相似文献

This study compared social values and relationships with parents among American college women of Chinese and European descent. Chinese-American women scored higher on a measure of practicality and pragmatism (mastery), hierarchy, and traditionality. The Euro-American women showed a greater interest in voluntary prosocial behaviour and philanthropy. Both groups of women reported having a sense of self, autonomous of their parents. Within the Chinese-American group, ethnic identification and religion, but not generation, moderated scores on a measure of traditionality of outlook regarding issues of law and order and social equality. We discuss the implications of our findings for recent debates in cross-cultural psychology, including the growing challenge to the individualism-collectivism dimension. 相似文献

Computational models of colour vision assume that the biological function of colour vision is to detect surface reflectance. Some philosophers invoke these models as a basis for externalism about perceptual content (content is distal) and objectivism about colour (colour is surface reflectance). In an earlier article (Thompson et al. 1992), I criticised the computational objectivist position on the basis of comparative colour vision: There are fundamental differences among the colour vision of animals and these differences do not converge on the detection of any single type of environmental property. David R. Hilbert (1992) has recently defended computational objectivism against my comparative argument; his arguments are based on the externalist approach to perceptual content originally developed by Mohan Matthen (1988) and on the computationally inspired theory of the evolutionary basis for trichromacy developed by Roger N. Shepard (1990). The present article provides a reply to Hilbert with extensive criticism of both Matthen's and Shepard's theories. I argue that the biological function of colour vision is not to detect surface reflectance, but to provide a set of perceptual categories that can apply to objects in a stable way in a variety of conditions. Comparative research indicates that both the perceptual categories and the distal stimuli will differ according to the animal and its visual ecology, therefore externalism and objectivism must be rejected.Versions of this article were read to the Department of Philosophy at the University of Chicago and to the Department of Philosophy at Boston University. I am grateful to the audiences for the discussions that ensued. I am also grateful to an anonymous referee for constructive criticism of certain points in the article. Special thanks are due to my comparative colour vision collaborators, Adrian Palacios and Francisco Varela. 相似文献

In this study, female and male college dyads (primarily Caucasian) involved in a “romantic relationship” used schematic figures to rate their conceptions of body size on a variety of rating protocols, including actual self, ideal self, ideal opposite gender, perceived partner's ideal opposite gender, perceived partner's rating of self, and rating of partner's body size. Based on the reflected-appraisal literature and previous body image research on perceived—actual disparities in body size ratings, five discrepancy indices were created and related to dispositional levels of body image disturbance, eating dysfunction, and general psychological function (self-esteem, depression). The results clearly indicated gender differences in the particular predictor associated with all measures of disturbance. For females, the discrepancy between the Self rating and the Perceived Partner's Ideal Other Gender rating accounted for almost all of the variance associated with clinical indices of disturbance. For males, the discrepancy between the Self rating and the Actual Partner's Ideal Other Gender rating was the only important predictor to emerge in regression analyses. The findings are interpreted in light of recent research on actual/perceived differences in body size ratings. 相似文献
