Using a Piagétan perspective, this study investigated the ways in which elementary school children perceive changes in the size of a televised image (in this case, a candy bar). The findings suggest that younger children perceive changes in image size from a medium shot to a close-up as changes in the object itself. Children's responses to changes in the televised image parallel their responses to traditional conservation tasks, but conservation of televised images occurs at a later age. In addition, children appear to use different cognitive skills to interpret how a zoom or a cut transforms the size of a televised image. When a zoom is used, children more readily perceive the object as “growing larger.”  相似文献

Our aim was to explore the role of parents in the transmission of stereotypical body size attitudes and awareness of weight loss strategies to preschool children. Participants were 279 3‐year‐old children and their parents, who provided data at baseline and 1 year later. Parents completed self‐report body size attitude and dieting measures. Child weight bias and awareness of weight loss strategies were assessed through interview. Over time, negative associations with large bodies and awareness of weight loss strategies increased. Fathers’ attitudes prospectively predicted boys’ weight bias and awareness of weight loss strategies. Among girls, parental attitudes were less predictive. Findings confirm the importance of fathers in the development of boys’ body attitudes and inform prevention programmes.  相似文献

This study examined the fairness reactions to 10 personnel selection methods in a sample of Italian students. University students (N=137) were asked to rate the favorability of these selection procedures and then to evaluate them on eight procedural justice dimensions. Work‐sample tests were the most favorably rated of the selection methods, followed by résumés, written ability tests, interviews and personal references. Graphology was perceived negatively. Opportunity to perform and the perceived face validity of selection procedures were the strongest procedural justice dimensions for predicting the process favorability ratings. The results of this study are compared with those from similar studies conducted in other countries. Similar results have been found in the various countries where such research has been conducted to date.  相似文献
