Nonverbal motion cues (a clenched fist) convey essential information about the intentions of the actor. Individuals with anorexia nervosa (AN) have demonstrated impairment in deciphering intention from facial affective cues, but it is unknown whether such deficits extend to deciphering affect from body motion cues.
We examined the capacities of adults with AN (n = 21) or those weight restored for ≥12 months (WR; n = 20) to perceive affect in biological motion cues relative to healthy controls (HC; n = 23).
Overall, individuals with AN evidenced greater deficit in discriminating affect from biological motion cues than WR or HC. Follow-up analyses showed that individuals with AN differed especially across two of the five conditions—deviating most from normative data when discriminating sadness and more consistently discriminating anger relative to WR or HC.
Implications of these findings are discussed in relation to some puzzling interpersonal features of AN. © 2012 by Wiley Periodicals, Inc. (Int J Eat Disord 2013)

    • "Our result is in accordance with some earlier findings (Medina-Pradas et al., 2012; Mendlewicz et al., 2005), which highlighted that both groups had similar abilities in decoding negative, positive and neutral emotions at the RMET. On the other hand, other studies showed difficulties in women with AN with recognising and describing specific emotions compared to controls: negative (Kucharska-Pietura et al., 2003; Zucker et al., 2013), both negative and neutral (Pollatos et al., 2008) or both positive and negative (Oldershaw et al., 2010).

    ABSTRACT: Introduction: The present study aimed to investigate mindreading abilities in female adolescent patients with AN compared to healthy controls (HCs), analysing differences for emotional valence of facial stimuli. Methods: The Eating Disorder Inventory) for evaluating psychological traits associated with eating disorders and the Children's version of the Reading the Mind in the Eyes Test for evaluating mindreading abilities were administered to 40 Italian female patients (mean age = 14.93; SD = 1.48) with restrictive diagnosis of anorexia nervosa (AN) and 40 healthy females (mean age = 14.88; SD = 0.56). Results: No significant differences between the AN group and HCs for the Eyes Total score were found. Even when analysing emotional valence of the items, the two groups were equally successful in the facial recognition of positive, negative and neutral emotions. A significant difference was revealed for the percentage of correct responses of item 10 and item 15, where the AN group was less able to correctly identify the target descriptor (Not believing) over the foils than HCs. A significant difference was revealed in discriminating for affective emotions versus cognitive states; only for affective but not for cognitive states, patients with AN were found to perform better than controls on the mindreading task. Conclusions: Our study highlighted the importance of analysing and discriminating for different valences of facial stimuli when assessing mindreading abilities in adolescents with AN, so that more precise and specific treatment approaches could be developed for female adolescents with AN.

    • "In contrast, people with BN have little or no impairment in facial emotion recognition [52], and may be better than healthy controls at recognizing negative emotions [53]. In AN, interpreting emotional meaning from the voice [54,55], body movement [56] and from films [54] is also impaired. For the most part, these impairments are less marked after recovery, suggesting that they may be starvation, state effects. "

    ABSTRACT: To describe the evidence base relating to the Cognitive-Interpersonal Maintenance Model for anorexia nervosa (AN). A Cognitive-Interpersonal Maintenance Model maintenance model for anorexia nervosa was described in 2006. This model proposed that cognitive, socio-emotional and interpersonal elements acted together to both cause and maintain eating disorders. A review of the empirical literature relating to the key constructs of the model (cognitive, socio-emotional, interpersonal) risk and maintaining factors for anorexia nervosa was conducted. Set shifting and weak central coherence (associated with obsessive compulsive traits) have been widely studied. There is some evidence to suggest that a strong eye for detail and weak set shifting are inherited vulnerabilities to AN. Set shifting and global integration are impaired in the ill state and contribute to weak central coherence. In addition, there are wide-ranging impairments in socio-emotional processing including: an automatic bias in attention towards critical and domineering faces and away from compassionate faces; impaired signalling of, interpretation and regulation of emotions. Difficulties in social cognition may in part be a consequence of starvation but inherited vulnerabilities may also contribute to these traits. The shared familial traits may accentuate family members’ tendency to react to the frustrating and frightening symptoms of AN with high expressed emotion (criticism, hostility, overprotection), and inadvertently perpetuate the problem. The cognitive interpersonal model is supported by accumulating evidence. The model is complex in that cognitive and socio-emotional factors both predispose to the illness and are exaggerated in the ill state. Furthermore, some of the traits are inherited vulnerabilities and are present in family members. The clinical formulations from the model are described as are new possibilities for targeted treatment.

    ABSTRACT: Objective There is consistent evidence of difficulties in social cognition in adults with anorexia nervosa (AN), but less is known about adolescents. The aim of this study was to investigate the ability to recognise emotion expressed in body movement in adults and adolescents with AN.Method One hundred and ninety-three females participated in the study (AN = 97: 61 adults and 36 adolescents). The performance of participants with AN on a body emotion recognition task was compared to age-matched healthy controls (HC = 96).ResultsAN participants were significantly worse than HC recognising sadness, with adolescent AN participants showing worse performance overall. There were no difficulties in the recognition of other emotions.DiscussionThe results partially support previous studies and the literature on facial emotion recognition, showing poorer recognition of sadness in AN. The results also suggest that difficulties in emotion recognition through body movements may be more subtle than other socio-emotional difficulties observed in AN.
