国际厌恶与恐惧情绪图片的本土化评定与基于脑电的试用

Native Assessment of Disgust and Fear Picture from International Affective Picture System

目的:对国际情绪图片库的厌恶与恐惧图片进行中国本土化的评定与基于脑神经机制的适用研究。方法:实验一:采用被试自评的方式,选取210张国际图片,其中厌恶、恐惧、中性图片各70张,让中国被试评定这些图片的效价、唤醒度、厌恶度和恐惧度;实验二:使用事件相关电位技术,对实验一评定出来的图片进行在中国被试的试用效果研究。结果:实验一,经过四个维度的评定,挑选出135张图片,其中厌恶、恐惧、中性图片各45张;实验二结果表明,对于N1波,厌恶和恐惧图片与中性图片的波幅差异显著,但前两者之间的差异不显著,对于P2和N2波,厌恶、恐惧、中性图片三者之间的波幅均差异显著。结论:国际厌恶和恐惧图片的中国本土化评定与试用有效。

Objective： The study was to develop the disgust and fear pictures suitable for Chinese. Methods： With 53 undergraduates as participants, using self-reporting and event-related potential（ERP） measures, two experiments were con- ducted for assessment of disgust and fear pictures from International Affective Picture System and Pretest in Chinese. Re- sults： In experiment 1,210 IAPS pictures were rated for the valence, arousal, disgust and fear of the selected（70 disgust pic- tures, 70 fear pictures, 70 neutral pictures respectively）, and IAPS pictures 135 werer selected（45 pictures for disgust, fear and neural）. In experiment 2, The neural activation patterns showed early N 1 sensitivity and differences between negative and neutral emotion, and differences between disgust and fear pictures emerged in the later P2 and N2 components. Con- clusion： Our findings suggest that the assessment of disgust and fear Picture from International Mfective Picture System and pretest are adaptive to chinese culture.
