Abstract

Twenty restrained eaters (REs) and 20 unrestrained eaters (UREs) were studied via a distorting video image technique under three conditions: (1) baseline; (2) induction of negative mood (NM), (3) induction of positive mood (PM). Under each condition they were asked: (a) to estimate the actual width of their own body; (b) to focus attention on their bodily sensations and indicate how wide their body sensed and (c) to estimate the width of a water bottle. In addition, subjects answered a body shape questionnaire (BSQ). Main effects were found for the factors Group (REs gave higher estimates). Mood (estimates were higher after induction of negative mood), and Instruction (estimates were higher for sensed width of body). There were significant interaction effects for Group x Mood (estimations of REs were higher after induction of negative mood) and for Group x Mood x Instruction. Dissatisfaction with body shape (BSQ) was significantly correlated with the estimations of sensed body width after induction of negative mood.  相似文献

Abstract

The enactment of relatively easy-to-implement and relatively difficult-to-implement goal intentions was investigated in a field study of body weight maintenance for 141 university students. Three appraisal processes were examined as mechanisms for implementing intentions: self-efficacy, outcome expectancy, and affect towards means. The results showed that goal-directed dieting behaviours for men and women and goal-directed exercising/sport activities for men were influenced by the appraisals in a linear compensatory manner, and goal-directed exercising/sport activities for women were influenced by the appraisals via a three-way interaction. Self-efficacy, in particular, was a strong, pervasive determinant of both dieting and exercising/sport activities for men and women.  相似文献

This study used self-determination theory (Deci, E.L., & Ryan, R.M. (2000). The ‘what’ and ‘why’ of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11, 227–268.) to examine predictors of body image concerns and unhealthy weight control behaviours in a sample of 350 Greek adolescent girls. A process model was tested which proposed that perceptions of parental autonomy support and two life goals (health and image) would predict adolescents’ degree of satisfaction of their basic psychological needs. In turn, psychological need satisfaction was hypothesised to negatively predict body image concerns (i.e. drive for thinness and body dissatisfaction) and, indirectly, unhealthy weight control behaviours. The predictions of the model were largely supported indicating that parental autonomy support and adaptive life goals can indirectly impact upon the extent to which female adolescents engage in unhealthy weight control behaviours via facilitating the latter's psychological need satisfaction.  相似文献

Abstract

The aim of This study was to investigate the association between menopausal stage and age and women's perception of their body image. Females from a community sample (n = 304. age range from 35 to 65 years) volunteered to complete a structured questionnaire which contained the Multidimensional Body Self Relations Questionnaire (MBSRQ) and the Stunkard Body Shape Figure Scale. One hundred and twenty women were premenopausal, 76 women were perimenopausal and 108 were postmenopausal. The effects of age and menopausal stage could not be separated in ratings of appearance evaluation, fitness evaluation, current, ideal and societal ratings of the Stunkard Body Shape Figure Scale. Premenopausal women (who were likely to be younger) had more positive ratings of appearance evaluation and fitness evaluation than menopausal women (who were likely to be older). Women who were premenopausal nominated smaller figures from the Stunkard Body Shape Figure Scale for ratings of the current, ideal and societal body shape than women who were perimenopausal and postmenopausal. The implications of these findings as they relate to women as they progress through the menopausal transition and as they become older is discussed.  相似文献

Despite consensus that exposure to media images of thin fashion models is associated with poor body image and disordered eating behaviours, few attempts have been made to enact change in the media. This study sought to investigate an effective alternative to current media imagery, by exploring the advertising effectiveness of average-size female fashion models, and their impact on the body image of both women and men. A sample of 171 women and 120 men were assigned to one of three advertisement conditions: no models, thin models and average-size models. Women and men rated average-size models as equally effective in advertisements as thin and no models. For women with average and high levels of internalisation of cultural beauty ideals, exposure to average-size female models was associated with a significantly more positive body image state in comparison to exposure to thin models and no models. For men reporting high levels of internalisation, exposure to average-size models was also associated with a more positive body image state in comparison to viewing thin models. These findings suggest that average-size female models can promote positive body image and appeal to consumers.  相似文献

Social self preservation theory asserts that situations high in social-evaluative threat elicit increases in cortisol, a hormone released by the hypothalamic-pituitary-adrenal axis. Most tests of the theory have examined threats associated with social evaluation of a performance. Two experiments examined the effects of threatened social evaluation of one's physique. In Experiments 1 (n?=?50) and 2 (n?=?40), participants allocated to an experimental (threat) condition had significantly higher post-manipulation cortisol than participants in a control (no threat) condition. In Experiment 1, perceptions of social-evaluative threat were significantly correlated with post-manipulation cortisol levels. These results suggest that the threatened social evaluation of one's body can activate the cortisol response. Women who frequently experience such threats may be at increased risk for a variety of health conditions associated with chronic cortisol exposure.  相似文献

The current study investigated the association between the severity and duration of physical disability and body esteem. A total of 748 participants (367 males, 381 females) who had a physical disability and 448 participants (171 males, 277 females) who were able-bodied participated in the study. The results demonstrated that people with more severe physical disability experienced lower levels of body esteem than people with milder physical disabilities and able-bodied people. The duration of physical disability was not related to levels of body esteem. Except for the face, people with physical disabilities devalued all aspects of their body more than able-bodied people. For males with physical disability, the unique predictors of high body esteem were decreased need for assistance, higher self-esteem, lower depression and higher sexual esteem; for females with physical disability, the unique predictors were higher self-esteem and higher sexual esteem. Overall, the study suggested that people with physical disability, particularly those with severe disabilities, may be particularly vulnerable to problems associated with their body esteem.  相似文献

Receptive vocabulary and associated semantic knowledge were compared within and between groups of children with specific language impairment (SLI), children with Down syndrome (DS), and typically developing children. To overcome the potential confounding effects of speech or language difficulties on verbal tests of semantic knowledge, a novel task was devised based on picture-based semantic association tests used to assess adult patients with semantic dementia. Receptive vocabulary, measured by word-picture matching, of children with SLI was weak relative to chronological age and to nonverbal mental age but their semantic knowledge, probed across the same lexical items, did not differ significantly from that of vocabulary-matched typically developing children. By contrast, although receptive vocabulary of children with DS was a relative strength compared to nonverbal cognitive abilities (p < .0001), DS was associated with a significant deficit in semantic knowledge (p < .0001) indicative of dissociation between word-picture matching vocabulary and depth of semantic knowledge. Overall, these data challenge the integrity of semantic-conceptual development in DS and imply that contemporary theories of semantic cognition should also seek to incorporate evidence from atypical conceptual development.  相似文献

This fMRI study explores how nonlinguistic cues modulate lexical activation in the bilingual brain. We examined the influence of face race on bilingual language production in a picture-naming paradigm. Chinese–English bilinguals were presented with pictures of objects and images of faces (Asian or Caucasian). Participants named the picture in their first or second language (Chinese or English) in separate blocks. Face race and naming language were either congruent (e.g., naming in Chinese when seeing an Asian face) or incongruent (e.g., naming in English when seeing an Asian face). Our results revealed that face cues facilitate naming when the socio-cultural identity of the face is congruent with the naming language. The congruence effects are reflected as effective integration of lexical and facial cues in key brain regions including IFG, MFG, ACC, and caudate. Implications of the findings in light of theories of language processing and cultural priming are discussed.  相似文献

ResearcherS used two behavioral prompts to compare increases in safety belt use: a Click It or Ticket prompt or a Flash-for-Life prompt. Participants were 1,822 unbuckled drivers exiting two student parking lots of a large university. Research assistants identified unbuckled drivers, flashed one of the two prompts, and recorded whether drivers buckled after the prompt and the drivers' facial expressions and hand gestures. Findings and implications are discussed.  相似文献
