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

In this paper, I show that we should understand the direction of fit of beliefs and desires in normative terms. After rehearsing a standard objection to Michael Smith’s analysis of direction of fit, I raise a similar problem for Lloyd Humberstone’s analysis. I go on to offer my own account, according to which the difference between beliefs and desires is determined by the normative relations such states stand in. I argue that beliefs are states which we have reason to change in light of the world, whereas desires are states that give us reason to change the world. After doing this, I show how the view avoids various objections, including two from David Sobel and David Copp. The paper ends by briefly discussing the relevance of the view to the Humean theory of motivation. 相似文献

Neediness, as a maladaptive form of interpersonal dependency, has been implicated in a range of psychopathology, most commonly mood and personality disorders. In light of the literature's sparse and inconsistent findings, Bornstein, Hilsenroth, Padawer, and Fowler (2000) have called for a systematic evaluation of dependency's role across the spectrum of Axis II disorders. The current study of individuals without current or past Axis I diagnoses found that Neediness was significantly related to dimensions of dependent, borderline, and histrionic personality disorders. Implications for the assessment of interpersonal dependency and issues in need of further clarification are highlighted. 相似文献

One of the most robust experience-related cortical dynamics is reduced neural activity when stimuli are repeated. This reduction has been linked to performance improvements due to repetition and also used to probe functional characteristics of neural populations. However, the underlying neural mechanisms are as yet unknown. Here, we consider three models that have been proposed to account for repetition-related reductions in neural activity, and evaluate them in terms of their ability to account for the main properties of this phenomenon as measured with single-cell recordings and neuroimaging techniques. We also discuss future directions for distinguishing between these models, which will be important for understanding the neural consequences of repetition and for interpreting repetition-related effects in neuroimaging data. 相似文献

Ellis and Beaton (1993a) reported that the keyword method of learning enhanced memory of foreign vocabulary items when receptive learning was measured. However, for productive learning, rote repetition was superior to the keyword method. The first two experiments reported here show that, in comparison with rote repetition, both receptive and productive learning can be enhanced by the keyword method, provided that the quality of the keyword images is adequate. In a third experiment using a subset of words from Ellis and Beaton (1993a), the finding they reported, that for productive learning rote repetition was superior to the keyword method, was reversed. The quality of keyword images will vary from study to study and any generalisation regarding the efficacy of the keyword method must take this into account. 相似文献

Advance preparation reduces RT task-switching cost, which is thought to be evidence of preparatory control in the cuing task-switching paradigm. In the present study, we emphasize errors in relation to response speed. In two experiments, we show that (1) task switching increased the rate at which the currently irrelevant task was erroneously executed ("task errors") and (2) advance task preparation reduced the task error rate to that seen in nonswitch trials. The implications of the results to the hypothesis concerning task-specific preparation are discussed. 相似文献

Auditory trace fear conditioning is a hippocampus-dependent learning task that requires animals to associate an auditory conditioned stimulus (CS) and a fear-producing shock-unconditioned stimulus (US) that are separated by an empty 20-s trace interval. Previous studies have shown that aging impairs learning performance on hippocampus-dependent tasks. This study measured heart rate (HR) and freezing fear responses to determine if aging impairs hippocampus-dependent auditory trace fear conditioning in freely moving rats. Aging and Young rats received one long-trace fear conditioning session (10 trials). Each trial consisted of a tone-CS (5 s) and a shock-US separated by an empty 20-s trace interval. The next day rats received CS-alone retention trials. Young rats showed significantly larger HR and freezing responses on the initial CS-alone retention trials compared to the Aging rats. A control group of aging rats received fear conditioning trials with a short 1-s trace interval separating the CS and US. The Aging Short-Trace Group showed HR and freezing responses on the initial CS alone retention trials that were similar to the Young Long-Trace Group, but greater than the Aging Long-Trace Group. A second aging control group received unpaired CSs and USs, and showed no HR or freezing responses on CS-alone retention trials. These data show that HR and freezing are effective measures for detecting aging-related deficits in trace fear conditioning. 相似文献
