Although prior research has shown that sexual objectification has the potential to undermine women’s cognitive performance, studies investigating this possibility have yielded mixed results. In particular, the impact of exposure to a thin-idealized body type on women’s cognitive processing is unexplored. We will randomly assign female participants to either an experimental condition in which participants will view photos of a thin female fashion model or a control condition in which participants will view photos depicting product advertisements without people. Participants will then complete an arithmetic task designed to gauge attention and working memory. I expect that participants exposed to the thin-ideal will have poorer cognitive performance than will participants assigned to the control condition. This study could have several clinical implications regarding the potency of the thin-ideal and its potential to negatively impact attention and cognitive function. This could prove to be useful in the development and implementation of interventions aimed at mitigating the effects of body dysmorphia and disordered eating.
