Although there is substantial evidence of visual attentional biases in processing weight-related information among individuals with weight dissatisfaction, few studies have examined auditory attentional biases in these individuals. The identification of attentional biases may provide an impetus for interventions to reduce distress, negative body image, and pathological eating patterns among weight-dissatisfied individuals. Therefore, the present study aimed to investigate the attentional biases, as well as the neural consequences, toward auditory weight-related information among weight-dissatisfied young females. In this experiment, young female participants were assigned to an experimental group with high weight dissatisfaction (HWD) and a control group with low weight dissatisfaction (LWD) according to the levels of weight dissatisfaction. Using a spatial cueing paradigm, auditory fatness-related, thinness-related, and neutral household words were presented laterally as cue stimuli, followed by visual stimuli presented at either the cued or uncued location. The results revealed that auditory fatness-related words elicited significantly larger N2ac amplitudes than auditory thinness-related and neutral words in the HWD group. However, for the LWD group, thinness-related words elicited a significantly larger N2ac than fatness-related and neutral words. These results suggest an orienting attentional bias toward auditory fatness-related body words among females with HWD and an orienting attentional bias toward auditory thinness-related words among females with LWD.
尽管有大量证据表明,在对与体重相关的信息进行处理时,体重不满的个体存在视觉注意力偏见,但很少有研究检查过这些个体的听觉注意力偏见。识别注意力偏见可能为减少体重不满个体的痛苦、负面身体形象和病理性进食模式的干预措施提供动力。因此,本研究旨在调查体重不满的年轻女性对听觉体重相关信息的注意力偏见及其神经后果。在这个实验中,根据体重不满程度,年轻女性参与者被分配到高体重不满实验组(HWD)和低体重不满对照组(LWD)。使用空间提示范式,将听觉肥胖相关、消瘦相关和中性家庭词汇作为提示刺激呈现在侧面,然后在提示或未提示位置呈现视觉刺激。结果表明,在 HWD 组中,听觉肥胖相关词汇诱发的 N2ac 振幅明显大于听觉消瘦相关词汇和中性词汇。然而,对于 LWD 组,消瘦相关词汇诱发的 N2ac 振幅明显大于肥胖相关词汇和中性词汇。这些结果表明,HWD 女性对听觉肥胖相关身体词汇存在定向注意力偏见,而 LWD 女性对听觉消瘦相关词汇存在定向注意力偏见。
