Studies show that touch in adults is referenced to a representation of the body that is structured topologically according to body parts; the perceived distance between two stimuli crossing over a body part boundary is elongated relative to the perceived distance between two stimuli presented within one body part category. Here we investigate this influence of body parts on tactile space perception in children of 5, 6 and 7 years of age. We presented children with pairs of tactile stimuli on the left hand/arm, either within the hand, within the forearm, or over the wrist. With their eyes closed children were asked to adjust the distance between the thumb and forefinger of their right hand to represent the felt distance between the two tactile stimuli. Like adults, the children perceived the distance between two stimuli that cross the body part boundary to be further apart than those that were presented within the hand or arm. They also perceive tactile distance to be greater on the hand than the arm which is the first observation of Weber's illusion in young children. We propose that a topological mode of body representation is particularly advantageous during early life given that body part categories remain constant while the metric proportions of the body change substantially as the child grows.  相似文献

Using prospective data collected across 14 years by the National Youth Survey Family Study (N = 1,436), we assessed change in aspirations, future expectations, and strain, as well as contemporaneous and longitudinal effects of these predictors on drug use, offending, and the perpetration of intimate partner violence. Growth curve models showed that, although time significantly predicted change in these variables, trajectories remained relatively stable. Contemporaneous random-intercept regression models revealed that all three measures were associated with all three problem behaviors. The effects were predictive longitudinally but some associations and gender differences were attenuated when controlling for prior involvement in outcomes.  相似文献

Abstract

College preparation programs, such as College Bound, aim to increase low-income students’ preparation for achieving future goals. Yet, little research has examined the nature of these students’ future goals and purposes from their own perspectives. In this study, in-depth interviews with 10 adolescents (six males and four females) participating in College Bound were analyzed using a qualitative approach informed by grounded theory. Four interrelated themes related to the development of youth purpose emerged: (a) people; (b) propensity; (c) passion; and (d) prosocial benefits. These themes were further categorized across two major dimensions: influences (i.e. capability and motivation) and sources of such influences (i.e. intrinsic and extrinsic). Moreover, ways in which students’ unique social contexts contributed to their experiences of purpose are discussed. Findings inform an understanding of the development of purpose in underrepresented youth, as well as provide insights for programs designed to promote their positive development and post-secondary school success.  相似文献

To assess current attitudes to body weight and shape in the South Pacific, a region characterised by relatively high levels of obesity and traditionally positive views of large bodies, 38 high socio-economic status (SES) adolescent males and 38 low SES adolescent males in Independent Samoa were asked to rate a set of images of real women for physical attractiveness. Participants in both SES settings preferred women with a slender figure, as did a comparison group in Britain, suggesting that the traditional veneration of large bodies is no longer apparent in Samoa. However, the results also showed that low SES adolescents were more likely to view overweight figures as attractive, which suggests that the veneration of slim figures may be associated with increasing SES. Implications of this finding are discussed in conclusion.  相似文献

Although a great deal of research has focussed on and continues to focus on fraud prevention and detection, there is still no reliable way to predict who will become a white‐collar criminal/fraudster. Significant benefits would result if and when this can be done. This paper recognizes that there are many common characteristics that exist among fraudsters and investigates whether fraud can be predicted based on the psychological, sociological, and environmental state of children throughout their upbringing. Research shows that children with a negative childhood develop negative habits, emotions, and mentalities, including disorders that can linger well into their adult lives. These negative characteristics can ruin relationships and possibly even influence an individual to commit fraud. This paper provides initial evidence regarding the potential significance of some childhood characteristics that may contribute to the likelihood that someone will become a white‐collar criminal. Given that no other similar research exists, this paper may help guide future researchers who are also attempting to solve this complex problem.  相似文献
