Object recognition research is typically conducted using 2D stimuli in lieu of 3D objects. This study investigated the amount and complexity of knowledge gained from 2D stimuli in adult chimpanzees (Pan troglodytes) and young children (aged 3 and 4 years) using a titrated series of cross-dimensional search tasks. Results indicate that 3-year-old children utilize a response rule guided by local features to solve cross-dimensional tasks. Four-year-old toddlers and adult chimpanzees use information about object form and compositional structure from a 2D image to guide their search in three dimensions. Findings have specific implications to research conducted in object recognition/perception and broad relevance to all areas of research and daily living that incorporate 2D displays. 相似文献

In a 2‐phase study with a total of 392 participants, depressive symptoms mediated the association between disordered eating and lower problem‐solving confidence and an avoidance problem‐solving style. Depressive symptoms did not mediate the association between the ability to generate competent solutions to hypothetical stressful situations and disordered eating. Depressive symptoms appeared to influence responses to problem‐solving inventories/coping checklists but had less of an influence on open‐ended problem‐solving measures. 相似文献

What Causes Specific Language Impairment in Children? 总被引:2,自引:0,他引:2

ABSTRACT— Specific language impairment (SLI) is diagnosed when a child's language development is deficient for no obvious reason. For many years, there was a tendency to assume that SLI was caused by factors such as poor parenting, subtle brain damage around the time of birth, or transient hearing loss. Subsequently it became clear that these factors were far less important than genes in determining risk for SLI. A quest to find "the gene for SLI" was undertaken, but it soon became apparent that no single cause could account for all cases. Furthermore, although fascinating cases of SLI caused by a single mutation have been discovered, in most children the disorder has a more complex basis, with several genetic and environmental risk factors interacting. The clearest evidence for genetic effects has come from studies that diagnosed SLI using theoretically motivated measures of underlying cognitive deficits rather than conventional clinical criteria. 相似文献

The purpose of the present study was to test whether or not a biodata instrument could be used to predict turnover, organizational commitment, and job performance in healthcare organizations. A criterion‐related, predictive validation strategy was used using a sample of 672 employees from two different hospitals in the southeastern United States. Supervisory ra0tings of organizational commitment and job performance were highly correlated with responses to the organizational commitment scale and the total score on the biodata instrument, respectively. Actual turnover was correlated with responses to the retention scale, although the effect size was small. Additionally, the study examined the fairness of biodata in this context as it relates to differences in performance among minority and non‐minority candidates. The findings in this study suggest that using such an instrument may provide organizations with the potential to improve organizational commitment and job performance, while reducing turnover with minimal group differences. 相似文献

One particular aspect of the literature on preferences for female body shapes has focused on the purported universality of preferences for a low waist‐to‐hip ratio (WHR), despite substantial evidence of cross‐cultural variability in such preferences. In the present study, we examined the effects of manipulating women's profile WHR, breast size, and ethnicity on men's ratings of physical attractiveness and health. A total of 51 African men in South Africa, 56 British Africans, and 114 British Caucasians rated 12 line drawings that varied in two levels of ethnicity, three levels of WHR, and two levels of breast size. Overall, the results suggested that there were cross‐cultural differences in preferred body shape, with the preferred body configuration varying as a function of the ethnicity of the figure being rated. In addition, there was a strong positive correlation between ratings of attractiveness and health. These findings are discussed in relation to the interplay between culture and evolution in determining ideals of attractiveness. 相似文献

Bullying experiences and male sexual violence (SV) perpetration are major public health problems, and while extant literature suggests that they may share some developmental correlates, there is no established empirical link between being a perpetrator or victim of bullying and SV perpetration in the literature. Nonetheless, some SV prevention programs in the U.S. include bullying prevention components for elementary and middle-school aged children. Research is needed to test the hypothesized links between bullying experiences and SV perpetration to determine whether bullying prevention programs are likely to prevent SV perpetration. The purpose of this paper is to present results from a review of research on each of these topics and to discuss the potential shared and unique risk and protective factors within a social-ecological framework. The paper concludes with suggested directions for future research. 相似文献
