Time Course of Attentional Biases Toward Body Shapes in Women Who Are Overweight or Obese

Attentional Biases Towards Body-Related Stimuli in Healthy Males: A Systematic Review

Recent literature has discussed the role of attentional biases towards body-related stimuli. Specific foci have been on those with high levels of body image concerns and female samples. Unfortunately, there has been limited focus on male samples within existing literature. The aim of the current study was to provide a critical synthesis of the findings of existing studies exploring attentional biases in adult males towards body-related stimuli. Critical synthesis of the findings of 20 studies explored four key methodologies: eye-tracking, dot-probe, visual search, and other methodologies (e.g. ARDPEI task). The current review provides evidence of specific attentional biases towards body-related stimuli in adult males experiencing body image concerns. Similar patterns of attentional biases are also demonstrated in males with body image pathologies. However, there appears to be distinct patterns of attentional biases for male and female participants. It is recommended that future research considers these findings and utilises measures developed specifically for male samples. Furthermore, additional variables require further attention, i.e. reasons for engaging in social comparison and/or engaging in physical activity.

Attentional processing of body images in women with overweight and obesity

PURPOSE

Despite the claim to integrate body image interventions in obesity treatment, little is known about the mechanisms involved in maintaining body dissatisfaction in persons with overweight and obesity. Therefore, the present study sought to investigate attentional processing of body stimuli in women with overweight and obesity (OW).

METHODS

Women with OW (n = 82) and normal weight controls (NW; n = 44) conducted two eye-tracking paradigms. In the first paradigm, fixation duration on the subjectively most beautiful and ugliest body part of one's own and a weight-matched control body were analyzed. In the second paradigm, picture pairs including the own and a control body or object were presented and initial fixation orientation was measured. Automatic and intentional processing of the body pictures was manipulated by either indicating on which side which stimuli would appear or not.

RESULTS

Women with OW displayed a bias towards the ugliest as opposed to the most beautiful body part, whereas women with NW showed a balanced viewing pattern. Furthermore, both groups showed a preference for bodies relative to the object. However, only women with OW preferred their own relative to the control body during intentional processing.

CONCLUSION

Taken together, results point towards a self-focused and deficit-oriented gaze pattern in women with overweight and obesity. Targeting these processes might help to improve obesity treatment outcomes.

Blinded by bodies: Elevated eating disorder symptomatology is associated with increased attentional priority for thin bodies

Selective processing of female thin-ideal body imagery is associated with greater body dissatisfaction, and eating disorder-specific rumination has been shown to mediate this relationship. Across two studies, we employed a modified rapid serial visual presentation task (similar to that used within the emotion-induced blindness literature), such that participants searched for a task-relevant target that was sometimes preceded by a thin body, non-thin body, or neutral task-irrelevant distractor. Our first experiment (N = 372) revealed a "body-induced blindness" in an unselected female sample, such that bodies in general distracted attention more than neutral images, and non-thin bodies distracted more than thin-ideal bodies. In our second experiment, female participants were selected based on eating disorder symptomatology (N = 114). Females that exhibited elevated eating disorder symptoms were distracted more by thin bodies compared to those low in symptomatology, greater distraction from thin bodies was associated with greater body dissatisfaction, and this relationship was mediated by eating disorder-specific rumination. Altogether, our findings illustrate the persistent nature of attentional distortions that occur early in cognitive processing and across time for those high in eating disorder symptomatology.
