Body dissatisfaction and selective attention to thin-ideal bodies: The moderating role of attentional control

This is the final version. Available on open access from Elsevier via the DOI in this recordData availability: Materials, data, and analyses reported in the manuscript are available at: https://osf.io/b4vxp/It has been widely hypothesised that elevated body dissatisfaction is characterised by a biased pattern of attentional selectivity that reflects increased attention to stimuli portraying the thin-ideal. Empirical evidence in support of this notion, however, has been inconsistent. The current study aimed to examine the potential moderating role of attentional control in the association between body dissatisfaction and selective attentional responding to thin-ideal bodies. Female undergraduate students (N = 232) completed a self-report measure of body dissatisfaction followed by performance-based measures of attentional control and selective attention. Results provided support for the moderating role of attentional control. Specifically, a positive association between body dissatisfaction and biased selective attention towards thin-ideal bodies was evident only amongst individuals with relatively low levels of attentional control. A general association between body dissatisfaction and selective attention was not observed. These findings may explain previous inconsistent findings and highlight the importance of considering the potential role of attentional control in the expression of body dissatisfaction-linked attentional responding to thin-ideal bodies.Australian Research Council (ARC

Reliability and convergence of approach/avoidance bias assessment tasks in the food consumption domain

Theories of motivation posit that people will more readily approach positive or appetitive stimuli, and there has been growing interest in the relationship between biases in approach and avoidance behaviours for food cues and food craving and consumption behaviour. Two paradigms commonly employed by research to investigate this relationship are the approach-avoidance task (AAT) and the stimulus-response compatibility task (SRCT). However, it is yet to be determined whether the measures yielded by these tasks reflect the same processes operating in the food craving and consumption domain. The present study examined the internal reliability and convergence of AAT and SRCT paradigms in their assessment of biased approach to unhealthy compared with healthy food stimuli, and whether the measures yielded by the AAT and SRCT paradigms demonstrated associations with individual differences in food craving and eating behaviour. One hundred twenty-one participants completed an SRCT, an AAT using an arm movement response mode, and an AAT using a key-press response mode. The measures yielded comparable and acceptable levels of internal consistency, but convergence between the different task bias scores was modest or absent, and only approach bias as measured with the AAT task using an arm movement response mode was associated with self-report measures of eating behaviour and trait food craving. Thus, tasks did not converge strongly enough to be considered equivalent measures of approach/avoidance biases, and the AAT task using an arm movement response seems uniquely suited to detect approach biases argued to characterise maladaptive eating behaviour and craving.</p
