内感受觉察与不愉快图片增强的神经反应相关
Interoceptive awareness is associated with enhanced neural response to unpleasant images
一项纳入115名本科生的脑电研究显示，自我报告的内感受觉察水平越高，观看不愉快图片时晚期正电位（LPP）相对愉快和中性图片的增强幅度越大。研究同时重复了愉快和不愉快图片比中性图片诱发更强LPP的既往结果，提示内感受信念可能参与情绪信息的皮层加工。依据摘要，该结论来自相关性分析，尚不能推断因果。
Interoception, or perception of internal bodily signals, is thought to be an important contributor to emotional experience and cognition, and individual differences in interoceptive beliefs may affect cognitive processing of emotional information. Addressing this issue, the present study examined the correlation between self-reported interoceptive awareness and EEG markers of motivated attention to emotional versus neutral images. A sample of undergraduates ( n = 115) viewed images of neutral, pleasant, and unpleasant scenes while EEG was recorded, and the late positive potential (LPP) was extracted for each image type. Group results replicate prior findings of enhanced LPP signals for pleasant and unpleasant compared to neutral images. Moreover, a greater degree of enhanced LPP for unpleasant images (versus pleasant or neutral images) was positively correlated with self-reported interoceptive awareness. Results support the role of interoceptive beliefs in cortical processing of emotional information.
