Adolescent body image and psychosocial functioning 总被引:2,自引:0,他引:2
Researchers have highlighted the significance of a poor body image in the development of dysfunctional eating but have systematically investigated few other outcomes. The authors examined the relationships between different aspects of body image and psychosocial functioning. Participants were 245 boys and 173 girls from Grades 8 and 9 (M age = 13.92 years, SD = 0.69 years). Respondents completed measures of physical attractiveness, body satisfaction, body image importance, body image behaviors, appearance comparison, social physique anxiety, self-esteem, depression, anxiety, and same-sex and opposite-sex relations. Whereas girls tended to report a more negative body image than did boys, the relevance of body image to self-esteem was similar for boys and girls. Concern about others' evaluation of their bodies was especially important in understanding low female self-esteem, whereas for boys, ratings of general attractiveness most strongly predicted self-esteem. The authors found a negative body image to be unrelated to symptoms of negative affect but to be strongly associated with poor opposite-sex peer relationships, especially among boys. A negative body image also affected same-sex relations among girls. 相似文献

The two studies reported in this paper were designed to evaluate the efficacy of a multidimensional model of body image that incorporated the dimensions of perception, affect, cognition, and behavior. Study 1 selected items from established measures that were judged to reflect these four dimensions. This four-factor model was then tested in Study 2. The participants for Study 2 were 175 females. The results did not support the hypothesized four-factor model. An exploratory factor analysis revealed a model that consisted of three factors: Cognitions and Affect Regarding Body, Body Importance and Dieting Behavior, and Perceptual Body Image. Below-average-weight respondents rated the Cognitions and Affect Regarding Body factor as more important than did above-average-weight respondents. Below-average-weight respondents overestimated their body size, whereas average-weight and above-average-weight respondents made underestimates, with above-average-weight respondents underestimating their body size to a greater extent than average-weight respondents. The results highlight the multidimensionality of the body image construct and the difficulty in attempting to simplify this construct. Implications of these findings for better understanding problems among people with disturbed body image are discussed. 相似文献

Infants and toddlers discriminate amount: are they measuring? 总被引:1,自引:0,他引:1
Four experiments that show an early ability to encode and retain information about extent are presented. We found that infants discriminate between the heights of dowels in a habituation task. We also found that toddlers discriminate between heights on a choice task in which a target dowel is presented and removed and they then choose between the target and a foil. Until 4 years of age, however, discrimination occurs only in the presence of a perceptually salient standard. Adults do not require a perceptually present standard; they can assess extent across temporal or spatial gaps by imposing a standard (measure). The present findings indicate that infants and toddlers do not possess an adult ability to establish extent, but that they do possess a skill that provides a start point for this important intellectual achievement. 相似文献

Society provides messages about how people should ideally look and previous research has indicated these messages, both the actual messages provided and the perception of the message, influence body image. Research into male body image has shown males are concerned with having a lean and muscular body and as such, may want to decrease fat and increase their muscles. This paper explored the influence of a range of messages from parents, peers, and the media on a number of different measures of 362 adolescent boys’ body image and body change strategies. Specifically, messages about shape, food, exercise, losing weight and increasing muscles were explored in relation to satisfaction with weight and muscles, and the use of strategies to decrease weight and increase muscles. The findings indicated that parental messages were the strongest influence on body image and that parents, the media, and to a lesser extent messages from male friends were the strongest predictors of body change strategies. 相似文献

This study was conducted to examine factors associated with blaming the target of sexual harassment. Participants' experiences of sexual harassment, sexist attitudes, gender, gender role identity, age, worker or student status, and belief in a just world were included as independent variables. Level of blame was evaluated using a series of 12 vignettes that manipulated the gender of the target and harasser as well as the seriousness of the harassing behavior. The sample comprised 30 female and 32 male workers from two workplaces, whose ages ranged from 18 to 65 (M = 35) years, and 102 female and 18 male university students whose ages ranged from 17 to 40 (M = 21) years. Approximately 70% of the sample were from Anglo Australian background, and 30% from European, Middle Eastern or Asian background. Females experienced more sexual harassment than males did, although the male rate was higher than expected. Although the majority of subjects attributed little blame to the target, males blamed the target of sexual harassment more than females did, and workers blamed the target of harassment more than university students did. Worker status, sexist attitudes, and gender significantly predicted blame for the total sample. Gender-typing increased the blame of the target by males but not by females. Attribution of blame was significantly influenced by worker versus student status, which supports the social psychological perspective that gender-related behavior is context dependent. The findings from this study suggest that organisational culture and environment influence respondents' attitudes to sexually harassing behavior. 相似文献

Five experiments demonstrate how potential moral stigma leads people to underplay their susceptibility to sexually transmitted diseases (STDs) and dampens their interest in getting tested. After adding unprotected sex to a list of otherwise innocuous possible vectors for a disease, the authors found that infected people were perceived to be less moral (Experiment 1a), and individuals believed that if they had the disease, others would see them as less moral too (Experiment 1b). Adding this stigmatized vector also reduced reported testing intentions (Experiment 2) and perceived risk of exposure (Experiment 3)--a disjunction fallacy because adding a potential cause reduced estimated likelihood, in violation of basic probability rules. Finally, the authors replicated the effect in a computer virus analog (Experiment 4) and showed that it did not result from simply knowing that one has not engaged in the stigmatized behavior. Results suggest that avoidance of potential stigma can have dramatic health consequences, both for an individual's health decision and for health policy. 相似文献

The relation between subjects’ predicted and actual memory performance is a central issue in the domain of metacognition.
In the present study, we examined the influence of item similarity and associative strength on judgments of learning (JOLs)
in a cued recall task. We hypothesized that encoding fluency would cause a foresight bias, so that subjects would overestimate
recall of identical pairs (scale-scale), as compared with strong associates (weight-scale) or unrelated pairs (mask-scale).
In Experiment 1, JOLs for identical word pairs were higher than those for related and unrelated pairs, but later recall of
identical pairs was lower than recall of related pairs. In Experiment 2, the effect of encoding fluency (inferred from self-paced
study time) was examined, and a similar pattern of results was obtained, with subjects spending the least amount of time studying
identical pairs. We conclude that overconfidence for identical pairs reflects an assessment of item similarity when JOLs are
made, despite associative strength being a better predictor of later retrieval. 相似文献

Entorhinal cortex lesions induce significant reorganization of several homotypic and heterotypic inputs to the hippocampus. This investigation determined whether surviving heterotypic inputs after bilateral entorhinal lesions would support the acquisition of a learned alternation task. Rats with entorhinal lesions or sham operations were trained to acquire a spatial alternation task. Although the sham-operated rats acquired the task within about 3 weeks postsurgery, rats with bilateral entorhinal lesions failed to learn the task after 12 consecutive weeks of training despite heterotypic sprouting of the cholinergic septodentate pathway and the expansion of the commissural/associational fiber plexus within the dentate gyrus. Thus, heterotypic sprouting failed to ameliorate significantly the effects of bilateral entorhinal lesions. Rather, entorhinal lesions produced a persistent impairment of spatial memory, characterized by a mixture of random error production and perseverative responding. 相似文献
