摘　　要：采用情绪分类的经典研究范式,结合事件相关电位技术,研究个体对身体表情识别的行为与时间进程特点。行为结果表明:个体对愉快情绪的加工速度明显快于悲伤。脑电结果表明:(1)在N170上,个体在对悲伤身体表情的识别中诱发了更大的波幅,表现出了“负性偏向”。(2)在P2上,相对悲伤和中性身体表情,人们在识别愉快的身体表情时诱发了更大波幅。(3)在晚期成分上,相对中性身体表情,人们在识别愉快与悲伤情绪时诱发出更大波幅,表现出了“情绪效应”。实验结果表明个体对身体表情的加工与面孔表情的加工可能存在着相似的模式。“This study employed the event-related potential(ERP)technique to investigate the time course of participants perceiving bodily expression emotional pictures.Behavioral results found the“positivity bias”,which means happy bodily expression are recognized faster compared to sad and neutral bodily expression.For ERP results:1)The N170 component confirmed the“negativity bias”effect,sad bodily expression elicited larger N170 components than happy and neutral.2)Compared to sad and neutral bodily expression,the P2 component amplitude increased to happy bodily expression.3)In the last stage,happy and sad bodily expression gained more attention instead of neural pictures,reflected by more pronounced LPP effects.Taken together,the current findings suggest human brains respond to nonverbal signals from the face and body in a similar manner.”
