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.
选择性处理女性理想化身体意象与更大的身体不满有关,而饮食障碍特异性的反刍思维已被证明可以介导这种关系。在两项研究中,我们采用了改良的快速序列视觉呈现任务(类似于情绪诱导性盲视文献中使用的任务),参与者在该任务中搜索与任务相关的目标,而该目标有时会先出现理想化身体、非理想化身体或中性无关分心物。我们的第一项实验(N=372)在一个未选择的女性样本中揭示了“身体诱导性盲视”,即身体总体上比中性图像更分散注意力,而非理想化身体比理想化身体更分散注意力。在我们的第二项实验中,根据饮食障碍症状选择了女性参与者(N=114)。与症状较轻的女性相比,表现出较高饮食障碍症状的女性更容易被理想化身体分心,对理想化身体的更大分心与更大的身体不满有关,而这种关系是由饮食障碍特异性反刍思维介导的。总的来说,我们的发现说明了在认知加工早期和高饮食障碍症状个体中,注意力扭曲具有持续存在的性质。
