Abstract

Visual attentional bias has important functions during the appearance social comparisons. However, for the limitations of experimental paradigms or analysis methods in previous studies, the time course of attentional bias to thin and fat body images among women with body dissatisfaction (BD) has still been unclear. In using free reviewing task combined with eye movement tracking, and based on event-related analyses of the critical first eye movement events, as well as epoch-related analyses of gaze durations, the current study investigated different attentional bias components to body shape/part images during 15s presentation time among 34 high BD and 34 non-BD young women. In comparison to the controls, women with BD showed sustained maintenance biases on thin and fat body images during both early automatic and late strategic processing stages. This study highlights a clear need for research on the dynamics of attentional biases related to body image and eating disturbances.

摘要

视觉注意偏向在外观社会比较中具有重要作用。然而,由于以往研究中实验范式或分析方法的局限性,身体不满意(BD)女性对瘦和胖身体形象的注意偏向的时间进程仍不明确。本研究采用自由回顾任务结合眼动追踪技术,基于对关键首次眼动事件的事件相关分析以及注视持续时间的时段相关分析,对34名高BD和34名非BD年轻女性在15秒呈现时间内对身体形状/部位图像的不同注意偏向成分进行了研究。与对照组相比,BD女性在早期自动和晚期策略加工阶段对瘦和胖身体图像均表现出持续的维持偏向。本研究凸显了对与身体形象和饮食障碍相关的注意偏向动态进行研究的迫切需求。
