This study aimed to analyze the covert attentional time course in early body processing areas in women with high body concerns. Therefore, we assessed the effect of pictures of one's own body and other bodies as distractions from a demanding dot detection task in 24 women with low and 20 women with high body concerns. Participants were instructed to attend to flickering dots eliciting steady-state visual evoked potentials (SSVEP) measured by EEG. Both groups showed a sustained SSVEP amplitude reduction, which was more pronounced for average-weight or thin bodies than for overweight bodies. For women with high body concerns, SSVEP amplitudes decreased more in the case of pictures of their own body. The results indicate covert vigilance and maintenance patterns for body stimuli, especially for bodies representing the thin ideal. Moreover, women with high body concerns attend more to information about their own body, which might maintain body dissatisfaction.
本研究旨在分析身体关注度高的女性早期身体加工区域的隐蔽注意时间进程。因此，我们评估了自己身体和他人身体图片作为一项要求较高的点检测任务的干扰因素对24名身体关注度低的女性和20名身体关注度高的女性的影响。参与者被指示关注闪烁的点，这些点会引发通过脑电图（EEG）测量的稳态视觉诱发电位（SSVEP）。两组均表现出持续的SSVEP振幅降低，平均体重或瘦体型身体的这种降低比超重体型身体更明显。对于身体关注度高的女性，自己身体图片情况下的SSVEP振幅下降更多。结果表明对身体刺激的隐蔽警觉和维持模式，尤其是对于代表瘦理想体型的身体。此外，身体关注度高的女性更多地关注有关自己身体的信息，这可能会维持身体不满意感。
