Differences in eye-movement patterns between anorexic and control observers when judging body size and attractiveness

Attentional biases may influence the eye-movements made when judging bodies and so alter the visual information sampled when making a judgment. This may lead to an overestimation of body size. We measured the eye-movements made by 16 anorexic observers and 16 age-matched controls when judging body size and attractiveness. We combined behavioural data with a novel eye-movement analysis technique that allowed us to apply spatial statistical techniques to make fine spatial discriminations in the pattern of eye-movements between our observer groups. Our behavioural results show that anorexic observers overestimate body size relative to controls and find bodies with lower body mass indexes more attractive. For both judgments, the controls' fixations centre on the stomach, but the anorexic observers show a much wider fixation pattern extending to encompass additional features such as the prominence of the hip and collar bones. This additional visual information may serve to alter their behavioural judgments towards an overestimation of body size and shift their ideal body size towards a significantly lower value.     

The importance of body satisfaction to physical self‐concept and body mass index in Spanish adolescents

This research examines the association between measured body mass index (BMI) and the perception of BMI by young students. Moreover, this research tests the importance of BMI and self‐concept, in order to predict body dissatisfaction in high school students. The sample consisted of 2087 individuals from different high schools in Extremadura, Spain, both males (n = 1046) and females (n = 1041), ranging in age from 15 to 17 years old (M = 15.42; SD = 0.86). Initially, participants' BMIs were assessed through anthropometry. Later, all individuals were asked about their weight and height, and their self‐reported BMI was calculated. Participants also answered a questionnaire about their perception of self‐concept, as well as completed a test about body image perception using Stunkard images. Outcomes revealed that factors concerning self‐concept and perceived BMI explained body dissatisfaction. Finally, results are discussed with the aim of improving knowledge in body dissatisfaction context.     

Muscle and fat aftereffects and the role of gender: Implications for body image disturbance

Body image disturbance – a cause of distress amongst the general population and those diagnosed with various disorders – is often attributed to the media’s unrealistic depiction of ideal bodies. These ideals are strongly gendered, leading to pronounced fat concern amongst females, and a male preoccupation with muscularity. Recent research suggests that visual aftereffects may be fundamental to the misperception of body fat and muscle mass – the perceptual component of body image disturbance. This study sought to establish the influence of gender on these body aftereffects. Male and female observers were randomly assigned to one of four adaptation conditions (low-fat, high-fat, low-muscle, and high-muscle bodies) and were asked to adjust the apparent fat and muscle levels of male and female bodies to make them appear as ‘normal’ as possible both before adaptation and after adaptation. While neither the gender of observers nor of body stimuli had a direct effect, aftereffect magnitude was significantly larger when observers viewed own-gender (compared with other-gender) stimuli. This effect, which may be due to attentional factors, could have implications for the development of body image disturbance, given the preponderance of idealized own-gender bodies in media marketed to male and female consumers.     

The impact of advertisements featuring ultra‐thin or average‐size models on women with a history of eating disorders

Previous research demonstrates that exposure to ultra‐thin media models leads to increased body image concerns amongst women (Groesz, Levine, & Murnen, 2002 ). There is emerging evidence that attractive, average‐size models do not have this negative effect and can be effective in advertising (e.g. Halliwell & Dittmar, 2004 ). The present study investigates these factors amongst women with a history of eating disorders. Participants either viewed advertisements featuring ultra‐thin, average‐size or control images. Immediately after exposure, they reported their body‐focused anxiety and rated the effectiveness of the advertisements. Whereas exposure to ultra‐thin models did not lead to increased body‐focused anxiety, exposure to average‐size models produced a relief effect, whereby women reported lower levels of body‐focused anxiety. Advertisements featuring ultra‐thin and average‐size models were equally effective. The results suggest that average‐size, attractive models could be used effectively in advertising, which may help to relieve body image concerns amongst these women.

Body image in bulimic,dieting, and normal females

The present investigation examined body-size estimation and overvaluation of a thin shape in bulimic females, females having been obese as adults who later lost weight, females with no history of obesity who were dieting, and females with no history of obesity as adults and not currently dieting. Each subject was presented with a set of seven silhouettes, one having been drawn from the subject's actual photograph and the remaining silhouettes representing 2.5, 5, and 7.5% increases and decreases in the size of certain body areas of the original figure. Subjects selected both their actual size and their ideal size. In addition, objective raters selected an ideal size for each subject. The hypotheses that bulimics would overestimate their size or overvalue an ultrathin body size as compared with other females were not supported. A history of childhood obesity appears to influence significantly body-size overestimation. Finally, the hypothesis that bulimics would appear more dissatisfied with their body image was not supported, with the three groups currently dieting appearing equally dissatisfied with their shape.The authors greatly appreciate the assistance of the graphic artist, Susan Meier.     

An assessment of body appreciation and its relationship to sexual function in women

Objectification theory posits internalization of an observer's gaze may negatively impact women's feelings about their bodies, which may subsequently affect their sexual function. Subjective body image and body size (i.e., body mass index [BMI]) have mixed relationships to women's sexuality, but assessment of positive body image as a sign of resistance to objectification has not been researched. This study explored relations between body appreciation and sexual function in women and assessed whether body size impacted this relationship. Cross-sectional data were collected online from 247 women, ages 18 to 58. Body appreciation scores were modestly negatively correlated with BMI, while BMI was not related to sexual function scores. After controlling for sexual orientation, partner status, and age, body appreciation predicted the arousal, orgasm, and satisfaction aspects of sexual function. Practitioners’ encouragement of body appreciation may improve sexual function in a way that encouraging a reduction in body size may not.     

Two‐year‐olds’ understanding of self‐symbols

This study investigated 48 2.5‐year‐olds’ ability to map from their own body to a two‐dimensional self‐representation and also examined relations between parents’ talk about body representations and their children's understanding of self‐symbols. Children participated in two dual‐representation tasks in which they were asked to match body parts between a symbol and its referent. In one task, they used a self‐symbol and in the other they used a symbol for a doll. Participants were also read a book about body parts by a parent. As a group, children found the self‐symbol task more difficult than the doll‐task; however, those whose parents explicitly pointed out the relation between their children's bodies and the symbols in the book performed better on the self‐symbol task. The findings demonstrate that 2‐year‐old children have difficulty comprehending a self‐symbol, even when it is two‐dimensional and approximately the same size as them, and suggest that parents’ talk about self‐symbols may facilitate their understanding.     

The influence of materialism and ideal body internalization on body‐dissatisfaction and body‐shaping behaviors of young men and women: Support for the Consumer Culture Impact Model

Exposure to media images of the ‘body‐perfect’ ideal has been partly blamed for the pursuit of thinness among women and muscularity among men. Research has largely overlooked the materialistic messages frequently associated with these images. We present findings from two studies with Icelandic students aged 18–21, one focusing on young women (n = 303) and one on young men (n = 226), which test associations of materialistic and body‐perfect ideals with body dissatisfaction and excessive body shaping behaviors. In both studies, the internalization of materialistic values is strongly linked to the internalization of body‐perfect ideals: the thin‐ideal for young women, and the muscular‐ideal for young men. A materialist value orientation also predicted body dissatisfaction in both studies, and was linked to body shaping behaviors, albeit differently for young women and men. Thus, the research identifies materialism as a further correlate of both body dissatisfaction and excessive body‐shaping behaviors. The findings support Dittmar's ( 2008 ) Consumer Culture Impact Model, which proposes that the body‐perfect and ‘material good life’ ideals jointly impact well‐being.     

The psychometric properties of several measures of body image

Despite the recent upsurge of interest in the construct of body image, there is relatively little information on the psychometric properties of the instruments used to measure it. This study investigated the reliability and validity of several measures of body image and compared bulimics and normals on these measures. One hundred ten normal weight females, half of whom were diagnosed as bulimic, were administered two measures of affect toward one's body, two measures of perceptions of one's entire body, and three measures of perceptions of the size of specific body sites (face, shoulders, waist, and hips). In themain, the measures provided reliable indices of body image. Examination of the correlation matrix for the measures disclosed convergence for the affective measures of body image and for all but one of the perceptual measures of body image. There was also significant covariation between the affective and the perceptual measures. The multitrait-multimethod technique was used to investigate the construct validity of the measures concerned with perceptions of the size of body sites. The multitrait-multimethod matrices disclosed substantial convergence between perceptions of face, shoulder, waist, and hip size across the three measures. However, the measure which used kinesthetic estimates of body-site size produced low reliabilities and all three of the measures showed substantial method variance. Bulimics and normals differed significantly on both the affective and the perceptual components of body image.This study is based on the first author's masters thesis. Portions of this study were represented at the 1986 meeting of the Southeastern Psychological Association. A grant to the third author from the Anclote Psychiatric Center provided support for this research project.     

Weight‐Based Discrimination in Occupational Hiring and Helping Behavior1

This study explored weight‐based discrimination using a range of weight categories, as represented by images of real women with known body mass index (BMI). In the first study, 30 men rated each image according to likelihood of occupational hiring for a managerial post. In the second study, 28 men rated the same images for likelihood of helping behavior following a minor accident. Study results showed that individuals with a slender body weight (BMI = 19–20) were most likely to be hired and helped, while obese (BMI > 30) participants were least likely to be hired and helped. However, results also showed that emaciated (BMI < 15) individuals were likely to be discriminated against. Implications for real‐life settings are discussed.     

Cross‐cultural,population‐based study on adolescent body image and eating distress in Japan and Finland

This cross‐sectional population‐based survey compares the prevalence of self‐reported body image and eating distress symptoms among adolescents in Japan and Finland, and associations between emotional/behavioral problems, body image and eating distress from a cross‐cultural perspective. The study included 1,840 Japanese and 1,135 Finnish 8th grade students. The self‐reported questionnaire included the Body Image and Eating Distress Scale and Strengths and Difficulties Questionnaire (SDQ). The female adolescents from both Finland and Japan reported much greater dissatisfaction with, and concern about, their bodies than the males and Japanese females expressed even higher distress than Finnish females. High levels of body image and eating distress were associated with psychiatric problems measured with the SDQ. There was a significant three‐way interaction effect of body image and eating distress, gender and country with SDQ peer problems and prosocial behavior.     

Ideal body shape preferences and eating disorder scores in adolescent women

Abstract

Using the body figure-preference ratings of Fallon and Rozin (1985), this study investigated the relationship between body shape preferences and eating disorder scores in a sample of adolescent women. These young women were found to express a large degree of body dissatisfaction, which was positively related to eating disorder symptomology. For the sample as a whole, there was no difference between ratings of the ideal figure and that perceived as most attractive. However, the Bulimia and Perfectionism scales did offer unique prediction of the ideal figure, over and above the Attractive figure. It was concluded that young women with high bulimic scores wish to be thinner than what they perceive as attractive. The present study suggests that what motivates this wish is the search for perfectionism.     

Lonelier, lazier, and teased: the stigmatizing effect of body size

The authors conducted 2 studies to examine the stigmatization of the female and male body using photographic stimuli of real people. In the first study, 75 female and 55 male undergraduates rated a series of 50 photographs of women ranging in body mass index (BMI) on 3 items: gets teased, lonely, and lazy. Both male and female observers rated bodies on either side of BMI 19-20 kg/m2 higher for the gets teased and lonely items. For the lazy item, there was a clear pattern of greater stigmatization with increasing BMI. In the second study, 40 male and 40 female observers rated a series of photographs of the male body that varied in BMI and waist-to-chest ratio on the same items. Results showed that men and women judged overweight and more tubular men to be lazier, lonelier, and teased. These findings suggest that body size is an important characteristic to consider when examining body stigmatization among men and women. These results also show support for the beautiful-is-good bias.     

The Influence of Societal Factors on Female Body Image

Abstract

This study was designed to identify factors associated with the perceptual and attitudinal components of female body image. The influence of society and factors thought to mediate the relationship between body image and society (field dependence, locus of control, and self-esteem) were investigated. Age and body mass index (BMI) were also included as independent variables. A total of 101 female university students in Australia ranging in age from 18 to 55 years (M = 24.11) participated in the study. A video camera apparatus (VCA) was used to assess perceptual distortion of body size. The VCA, the Body Esteem Scale, and the Appearance Evaluation subscale of the Multidimensional Body Self Relations Questionnaire were used to assess body satisfaction. On average, women underestimated their body sizes by 4%, and they typically wanted to be smaller than their actual body sizes. About two fifths of the women expressed moderate to strong negative feelings about both individual body parts and their bodies as a whole. Multiple regression analyses revealed that perceptual distortion of body size could not be predicted from the independent variables. Body satisfaction was best explained by societal factors, self-esteem, and BMI.     

A comparison of body size ideals, body dissatisfaction, and media influence between female track athletes, martial artists, and non-athletes

ObjectivesIn assessments of body image among athletes, there remains an important discrepancy between studies reporting, on one hand, increased body dissatisfaction among athletes and, on the other, lower body image concerns. In order to help resolve this contradiction, the present study examined body size ideals, body dissatisfaction, and media influence among female recreational athletes and non-athletes.MethodForty-one track athletes (a judged sport in which leanness is actively promoted), 47 women involved in Taek Won Do (a martial art with little or no emphasis on leanness), and 44 non-athletes completed self-report measures of ideal body size, body dissatisfaction, and media influence, and provided their demographic details.ResultsResults showed that, after controlling for participants' body mass index (BMI), there were no significant between-group differences in ideal body size. By contrast, track athletes reported the highest body dissatisfaction scores and the highest internalisation of athletic media messages. Results of a regression analysis showed that, for the total sample, participants' BMI and internalisation of athletic media messages predicted body dissatisfaction over-and-above involvement in the different sports.ConclusionThese results support the suggestion that women participating in leanness-promoting sports experience greater body dissatisfaction than women in other sports or non-athletes.     

Perceptions of female body weight and shape among indigenous and urban Europeans

Two important cues to female physical attractiveness are body mass index (BMI) and body shape as measured by the waist-to-hip ratio (WHR). This study examined the relative contribution of both cues in three culturally distinct populations. A total of 119 Finnish, Sámi and British male observers rated a set of un-edited photographs of women with known BMI and WHR. The results showed that there were significant differences in preferences for physical attractiveness, with the indigenous Sámi preferring figures with larger BMIs and more tolerant of heavyweight figures than either Finnish participants in Helsinki or Britons in London, who were indistinguishable in their preferences for slim figures. The findings are discussed in terms of evolutionary psychological explanations of mate selection, and sociocultural theories which emphasizes the learning of preferences for body sizes in social and cultural contexts.     

Body-image disturbances in bulimia nervosa: influences of actual body size

This study evaluated body-image distortion and ideal body-size preferences in 423 nonbulimic women and 108 bulimics. Analyses of covariance were utilized to compare the bulimic and nonbulimic groups on measures of current and ideal body size. Weight was used as a covariate to evaluate the influence of actual body size on perception of current body size and selection of ideal body size. Bulimics chose current body sizes that were significantly larger than those picked by nonbulimics regardless of actual body size. Bulimics also chose thinner ideal body sizes than did nonbulimics, regardless of actual body size. These results suggest that body-image distortion and extreme preference for thinness are a fundamental characteristic of bulimia nervosa. These results were discussed in terms of how perception of a large body size and preference for a very thin body size might interact to produce a high degree of dissatisfaction and overconcern with body size in bulimia nervosa.     

Effects of a physical exercise session on state body image: The influence of pre-experimental body dissatisfaction and concerns about weight and shape

The effects of a physical exercise session on state body image and mood were examined. In a cross-over design, participants were randomised to two groups starting either with physical exercise (PE; experimental condition) or with reading a newspaper (RN; control condition). Before and after PE and RN, participants (N = 65) rated their body dimensions using a digital photo distortion technique and indicated their attitudinal body image and mood. Participants’ judgements of their ‘felt’ body dimensions and attitudes toward their own body were affected differently by PE and RN, indicating that participants felt slightly slimmer and were more satisfied with their bodies after PE. Exercise-induced changes in body perception were greater, the higher the pre-experimental drive for thinness, body dissatisfaction and weight/shape concerns were. Especially in those participants with higher body image disturbances, physical exercise can have a reinforcing effect on immediate body image and mood improvement.
