Subjective disgust and facial electromyography responses towards unedited and morphed overweight self-pictures in women with varying levels of eating disorder symptomatology

Individuals with an eating disorder (ED) often report to be disgusted by their body. Body-related self-disgust could play an important role in the development and maintenance of EDs. We investigated if women with relatively high ED symptom scores indeed respond with disgust upon exposure to their body as indexed by facial electromyography (fEMG) of the m. levator labii superioris and self-report. Given that one's self-disgust may increase/decrease depending on the relative distance of the own body to the thin ideal, we also assessed women's disgust for overweight- and thin-morphs of their body. Female undergraduate students (N = 104) were photographed and presented with their (morphed) body pictures, next to disgust-relevant and overweight body control pictures. Higher levels of ED symptoms were associated with stronger self-reported disgust to unedited body-pictures and overweight-morphs. Disgust to thin-morphs was unrelated to ED symptoms. Participants generally showed heightened facial disgust towards overweight morphs, yet the strength of facial disgust was unrelated to ED symptoms. Thus, the findings provide evidence for the involvement of heightened body-related self-disgust in ED symptomatology, albeit only on the basis of self-report

Reducing body dissatisfaction by means of an evaluative conditioning procedure in undergraduate women:A replication study

The aim was to investigate whether a computer-based evaluative conditioning (EC) procedure using positive social feedback is effective in enhancing body satisfaction. Prior findings in three small-scale studies were mixed showing positive effects in pre-clinical samples, but not in a clinical sample of eating disorder patients. Therefore, our main goal was to replicate the original finding of Martijn et al. (2010) in a well-powered unselected sample of 129 female undergraduates. We assessed the impact of EC on questionnaire measures of body satisfaction as well as on affective ratings of the participants' body pictures used in the task to verify whether the EC procedure was effective in heightening the subjective valence of these pictures. Supporting the validity of the current EC procedure, participants in the experimental condition rated their own pictures after the training as more positive than participants in the control condition. However, this effect of the EC procedure did not transfer to the self-report indices of body satisfaction. In addition, women with relatively high body concern did not profit more from the EC procedure than women with relatively low body concern. Together, these findings suggest that the EC procedure in its present form is not ready for use as an intervention for improving body satisfaction. However, it seems worthwhile to investigate in future studies how the EC procedure can be further strengthened in a way that effects on stimulus ratings eventually also 'spill over' to the level of self-reported body satisfaction.</p

What’s not to like? Enhancing women’s body satisfaction by means of an evaluative conditioning procedure with positive social feedback

The prevalence of a negative body image among women is high. Because of its serious consequences for individuals’ mental health, there is an urgent need to improve current body image interventions. Recent studies using evaluative conditioning to strengthen the association between women’s body and positive (social) stimuli have shown promising results. In two experimental studies, we tested whether incorporating more age appropriate positive social stimuli as unconditioned stimuli (USs) can strengthen the conditioning procedure as a means to enhance women’s body satisfaction. In the experimental condition, participants’ body pictures were systematically followed by the Facebook like-button and youthful smiling faces (study 1, experimental condition: n = 68; control condition: n = 67) or positive Emojis (study 2, experimental condition: n = 64; control condition: n = 67). The results indicated that neither conditioning procedure enhanced participants’ body satisfaction more than a control procedure, and in both studies, there was no valence transfer from the positive USs to the body pictures. Thus, incorporation of age appropriate USs did not result in the anticipated conditioning effects. These findings challenge the utility of current evaluative conditioning procedures as an intervention technique to address a negative body image

What you don’t know, can’t hurt you:The differential effect of masked versus non-masked counterconditioning and mere exposure to spider pictures on women’s affective evaluation of spiders

Exposure therapy is the treatment of choice for specific phobias but prolonged exposure to feared stimuli is strenuous and may lead to treatment dropout. Previous research showed that repeated exposure to masked spiders was effective in reducing psychophysiological and behavioural fear responses, but appeared ineffective in changing subjective feelings towards spiders. This study investigated in an unselected female sample if masked counterconditioning would be more effective in reducing spider dislike compared to masked exposure, and if masked counterconditioning would also be more effective than non-masked counterconditioning. Women with varying levels of spider aversion (N = 272) were randomly assigned to one of four conditions. Three spider pictures were always (counterconditioning) or never (exposure) followed by smiling faces. For half of the participants in each condition the spiders were masked. Results indicated that participants rated the spider more positively after both masked counterconditioning and masked exposure. However, the increase in valence after masked counterconditioning was not significantly larger than after mere masked exposure, or after non-masked counterconditioning. Thus, our findings show that repeated exposure to masked spider pictures is effective in reducing spider aversion, but they provided no support for the anticipated added benefit of pairing the spider with positive stimuli

The effectiveness of a masked counterconditioning approach using continuous flash suppression to alleviate body dissatisfaction in women with high body image concerns

BACKGROUND AND OBJECTIVES: Research that used counterconditioning (CC) to reduce women's negative body image has led to mixed results. One explanation could be that the negative responses elicited by own body pictures hinder the effectiveness of CC procedures in adjusting overly negative attitudes towards the own body. In this study we therefore tried to prevent the impact of negative responses by limiting women's perceptual awareness of the own body pictures during the CC procedure.METHODS: Women with a negative body image were randomly assigned to an experimental (n = 75) or control (n = 71) condition. In the experimental condition, participants' masked body pictures were systematically followed by visible social approval cues (i.e., smiling faces), whereas neutral body-unrelated control pictures were followed by a blank screen. In the control condition, both own body and control pictures were followed by a blank screen.RESULTS: Participants in the experimental condition did not report a more positive evaluation of the own body (pictures) after CC than participants in the control condition. Also, the strength of automatic affective body evaluations as indexed by a single-target Implicit Association Test did not differ between conditions.LIMITATIONS: Many participants did not remain fully unaware of their body pictures during conditioning.CONCLUSIONS: The findings provided no support for the idea that CC with masked own body pictures can be used in women with body dissatisfaction to improve their body image.</p
