This study aimed to identify the differences in body self-esteem, general self-esteem and eating attitudes in a representative sample of children, aged 9-12 years, attending school in México DF. The logistic regression model incorporated the variables of sex, general self-esteem, BMI, age and discrepancy between the perceived image and the ideal image. Participants with an increased risk of eating disorders were girls: a) with less general self-esteem; b) BMI at the upper range of normal weight; c) greater negative discrepancy between perceived and ideal image; d) aged 11-12 years. Higher general self-esteem would act as a protector for eating disorders, while the desire for a thinner ideal body would be a risk factor. 相似文献

Three experiments investigated the mental representation of meaningful event sequences. Experiment 1 used extended (5 min long) naturalistic scenes excerpted from commercial movies. Experiments 2 and 3 presented everyday activities by means of sequences of six photographs. All experiments found both left–right and distance
effects in an order decision task, suggesting that when contemplated in hindsight, experienced events unfold along a left-to-right
analogical mental line. Present results are discussed in the context of the mental representation of other kinds of ordinal
sequences, and other left–right effects reported in non-ordinal domains. 相似文献

Associative learning theory postulates two main determinants for human causal learning: contingency and contiguity. In line with such an account, participants in Shanks, Pearson, and Dickinson (1989) failed to discover causal relations involving delays of more than two seconds. More recent research has shown that the impact of contiguity and delay is mediated by prior knowledge about the timeframe of the causal relation in question. Buehner and May (2002, 2003) demonstrated that the detrimental effect of delay can be significantly reduced if reasoners are aware of potential delays. Here we demonstrate for the first time that the negative influence of delay can be abolished completely by a subtle change in the experimental instructions. Temporal contiguity is thus not essential for human causal learning. 相似文献

Individuals have affective associations with health behaviors. In other domains such associations have been shown to influence behavior, but affective associations with health behaviors are not included in current health decision-making models. The authors examined whether affective associations with exercise predicted individuals' activity behavior and, if so, how they interfaced with other decision-making constructs to influence behavior. Adult participants (N = 433) reported their current physical activity behavior and affective associations with physical activity. Health belief model and theory of planned behavior constructs were also assessed. More positive affective associations with activity significantly predicted greater activity behavior. Moreover, the influence of the health belief model and theory of planned behavior constructs on activity behavior was mediated through affective associations. Affective associations were shown to play a central role in individuals' activity behavior, both as a mediator of the effects of cognitively based decision-making factors and as an independent predictor of activity behavior. The results suggest the need to include affective influences on behavior in formal models of health decision making and, potentially, to explore affectively based intervention routes to change behaviors. 相似文献
