Two studies were conducted to explore the degree to which single- and multiple-risk profiles were evident in samples of African American early adolescents in low-income inner-city, rural, and suburban schools. Study 1 examined early adolescent risk status (i.e., single, multiple) in relation to later adjustment in a representative sample (70% European American, 30% African American). Youth who experienced a single risk in early adolescence had moderately increased levels of school dropout and criminal arrests, whereas youth with multiple risks (i.e., combination of 2 or more risks) had significantly increased levels of school dropout, criminal arrests, and teen parenthood. Study 2 examined the extent to which single- and multiple-risk profiles were evident in cross-sectional samples of African American youth from low-income inner-city and rural areas. About one fourth of both the inner-city and rural samples of African American youth were composed of youth in the single-risk category. A significantly greater proportion of boys in the inner-city sample (20%) than boys in the rural sample (13%) experienced multiple risks. Girls across the rural and inner-city samples did not differ in terms of risk. Overall, more than 60% of African American youth in these two low-income samples did not evidence risk for later adjustment problems. Implications for research and intervention are discussed.  相似文献

Teacher assessments of interpersonal characteristics were used to identify subtypes of rural African American early adolescents (161 boys and 258 girls). Teacher ratings of interpersonal characteristics were used to identify popular and unpopular aggressive subtypes for both boys and girls. Unpopular aggressive youths did not have elevated levels of rejected sociometric status but were more likely to have lower levels of peer-perceived social prominence and social skills. Conversely, popular aggressive youths were more likely to be disliked by peers even though they were perceived by peers as socially prominent and socially skilled and were identified by teachers as highly involved in extracurricular activities. Both popular and unpopular aggressive youths tended to associate with others who had similar levels of peer-perceived popularity.  相似文献

We examine a set of implicit and explicit claims about the concept of eye dominance that have been made over the years and note that the new literature on eye dominance does not reflect the old literature from the first half of the last century. We argue that the visual and oculomotor function of the dominant eye--defined by such criteria as asymmetry in acuity, rivalry, or sighting--remains unknown and that the usefulness of the concept for understanding its function is yet to be determined. We suggest that the sighting-dominant eye is the eye used for monocular tasks and has no unique functional role in vision.  相似文献

This essay forges links between Popperians and feminists by considering the connections between Donna Haraway's situated knowledge and Karl R. Popper's situational logic. It is concerned with the political commitments behind methodological issues, with the degree to which there can be a Popperian contribution to the feminist vision of a successor science, and with ways of dealing with, while not resolving, the political differences between socialist feminists and libertarian Popperians.  相似文献

The comparatively lower prevalence of eating disorders among Asian and Afro-Caribbean than Caucasian women in the UK has often been attributed to cultural differences in pressures for slimness. However, there have been no attempts to evaluate cultural differences in ideals for female physique directly among women in the at risk age groups. In the present study, cultural influences on body image were evaluated by comparing the body size ideals, body image and dieting concerns in a sample of 274 young white and Asian British women. The results indicate that Asian women are less likely to describe themselves as too fat, were less dissatisfied with their body size, less likely to want to lose weight and less restrained. However, Asian women were slimmer than white women and, after controlling for the difference in body size, the effects were reduced. The hypothesis that any body satisfaction differences could be explained by differences in ideal body size between the two groups were not supported; Asian women favoured even slimmer ideal body sizes than white women. Alternative explanations in terms of cultural differences in evaluation of fatness are discussed.  相似文献

Hering’s model of egocentric visual direction assumes implicitly that the effect of eye position on direction is both linear and equal for the two eyes; these two assumptions were evaluated in the present experiment. Five subjects pointed (open-loop) to the apparent direction of a target seen under conditions in which the position of one eye was systematically varied while the position of the other eye was held constant. The data were analyzed through examination of the relationship between the variations in perceived egocentric direction and variations inexpected egocentric direction based on the positions of the varying eye. The data revealed that the relationship between eye position and egocentric direction is indeed linear. Further, the data showed that, for some subjects, variations in the positions of the two eyes do not have equateffectsTjn egocentric direction. Both the between-eye differences and the linear relationship may be understood in terms of individual differences in the location of the cyclopean eye, an unequal weighting of the positions of the eyes in the processing of egocentric direction, or some combination of these two factors.  相似文献

Bullying and victimization are serious problems for youth of many ages and from a variety of backgrounds. These behaviors have not, however, been widely studied in rural minorities. The current work examined behavioral and social correlates of bullying and victimization in a sample of rural African American youth. Incidence rates of bullying, victimization, and aggressive victimization parallel those in other populations. Bullies were rated as aggressive, hyperactive, and manipulative. Bullies and victims were both sociometrically rejected, but while victims were on the margin of the social network, bullies were integrated in their groups. Bullies' associations were heterogeneous: they belonged to both aggressive and non-aggressive and popular and unpopular groups. They also were highly likely to be leaders of their groups.  相似文献
