“…In line with previous studies (Voges et al, 2018; Voges et al, 2017, 2019; von Wietersheim et al, 2012), we interpret our observations in the context of double standards for the own and other person's bodies. Our observations line up with studies (Cornelissen et al, 2015; Mergen et al, 2018; Mölbert et al, 2018) arguing that patients with AN do not show altered body representation in general, but rather a top–down cognitive–affective distortion in evaluating their own body. In this sense, social media contents that pick up weight based stereotypes and eating disorder symptoms (Branley & Covey, 2017; Cavazos‐Rehg et al, 2019) most likely reflect over‐occupation with weight and shape rather than shifted stereotypes.…”

“…To date, a significant proportion of clinical research on body image in AN was motivated by the question whether the patient's typical worries about being ‘too fat’ might be due to a perceptual deficit in judging body size and shape. Indeed, patients with AN frequently overestimate their body size in vision‐based body size estimation tasks (for a review see Mölbert, Klein, et al, 2017) and, partly, also show altered performance in nonvisual tasks assessing body perception (Engel et al, 2020; Gaudio, Brooks, & Riva, 2014; Mergen, Keizer, Koelkebeck, van den Heuvel, & Waner, 2018). However, the effect pattern seen in a meta‐analysis conducted by Mölbert, Klein, et al (2017) as well as several well‐controlled experimental studies (Cornelissen, Bester, Cairns, Tovee, & Cornelissen, 2015; Fernández Aranda, Dahme, & Meermann, 1999; Mölbert et al, 2018) suggest that the patients' idea of being ‘too fat’ is unlikely due to a deficit in representing the own body weight and dimensions accurately.…”

This study provides a comprehensive assessment of own body representation and linguistic representation of bodies in general in women with typical and atypical anorexia nervosa (AN). Methods: In a series of desktop experiments, participants rated a set of adjectives according to their match with a series of computer generated bodies varying in body mass index, and generated prototypic body shapes for the same set of adjectives. We analysed how body mass index of the bodies was associated with positive or negative valence of the adjectives in the different groups. Further, body image and own body perception were assessed. Results: In a German-Italian sample comprising 39 women with AN, 20 women with atypical AN and 40 age matched control participants, we observed effects indicative of weight stigmatization, but no significant differences between the groups. Generally, positive adjectives were associated with lean bodies, whereas negative adjectives were associated with obese bodies. Discussion: Our observations suggest that patients with both typical and atypical AN affectively and visually represent body descriptions not differently from healthy women. We conclude that overvaluation of low body weight and fear of weight gain cannot be explained by generally distorted perception or cognition, but require individual consideration.

“…The assessment of multisensory body representation is challenging. However, an increasing number of experimental paradigms have been developed in recent years to assess such concepts as: interoception [e.g., (73)(74)(75)], implicit knowledge of body dimensions (76)(77)(78) and multisensory integration (24). Despite reports of potentially disturbed multisensory integration and interoception in eating disorders (24,79,80), these measures have so far been largely neglected in clinical research.…”

Distorted representation of one's own body is a diagnostic criterion and corepsychopathology of disorders such as anorexia nervosa and body dysmorphic disorder. Previousliterature has raised the possibility of utilising physical activity intervention (PI) as atreatment option for individuals suffering from poor body satisfaction, which is traditionallyregarded as a systematic distortion in "body image." In this systematic review,conducted according to the PRISMA statement, the evidence on effectiveness of PI on body representation outcomes is synthesised. We provide an update of 34 longitudinal studies evaluating the effectiveness of different types of PIs on body representation. No systematic risk of bias within or across studies were identified. The reviewed studies show that the implementation of structured PIs may be efficacious in increasing individuals' satisfaction of their own body, and thus improving their subjective body image related assessments. However, there is no clear evidence regarding an additional or interactive effect of PI when implemented in conjunction with established treatments for clinical populations. We argue for theoretically sound, mechanism-oriented, multimethod approaches to future investigations on body image disturbance. Specifically, we highlight the need to consider expanding the theoretical framework for the investigation of body representation disturbances to include further body representations besides body image.

“…Several authors have suggested that body size over-estimation in conditions like AN might be explained solely in terms of changes in attitudinal body image (Mergen, Keizer, Koelkebeck, van den Heuvel, & Wagner, 2018;Mölbert et al, 2018;Smeets, 1997Smeets, , 1999, and tasks that purportedly measure perceptual body image may in fact be visual proxies for estimates of attitudinal body image. Based on this study of women who experienced high-level adaptation to images of female bodies at different BMIs, our results suggest that both attitudinal and perceptual tasks do indeed measure independent aspects of body image and to fully characterise this problem, both components must be fully understood.…”

Are attitudinal and perceptual body image the same or different? Evidence from high-level adaptation

et al. 2019

Highlights  Do measures of perceptual and attitudinal body image assess the same or different constructs?  The outcomes from a high-level body adaptation task for each case are hypothesized and tested.  Unambiguous support for independence between attitudinal and perceptual body image was found.  Novel suggestions how sufferers of anorexia nervosa come to overestimate their body size are offered.
