中老年人情绪刺激的事件相关电位研究

目的 探讨正确调节负性、中性情绪刺激,发挥正性情绪刺激对中老年人健康、智力、工作和生活的促进作用.方法 研究25例中老年人对正性、负性和中性简笔画面孔图片以及汉字"喜"、"思"、"恐"随机构成刺激序列的情绪刺激诱发的事件相关电位(ERP).结果 情绪的主效应分别出现于左侧颞顶区(40～80 ms),双侧顶枕和颞顶区(160～180 ms)和(310～340 ms);刺激的主效应分别出现于前头部(375～475 ms),后头部(195～255 ms),全头部(135～175 ms)和(275～355ms):情绪与刺激因素无显著交互效应.结论 成功的情绪调节是个体根据情境的变化,灵活地采取既有益于自身的身心健康又能适应社会环境需求的策略来控制自己的情绪;正性情绪刺激对中老年人健康、智力、工作和生活有促进作用.

Event-related potentials of emotional excitement in middle-aged and aged adults

Objective To explore how adjustment of the negative and neutral emotion excitement contribute to the well-being of middle-aged and aged adults in their health,intelligence,working and living.Methods Twenty-five middle-aged and aged participants performed recognition tasks of schematic facial representations of positive,neutral and negative emotions and also Chinese characters(equivalent to happy,thinking and fear).Results The main effects of the facial recognition task occurred in the left temporal-parietal area(40 to 80 ms),bilateral parietal-occipital and temporal-parietal area(160-180 ms and 310-340 ms).The effects of stimulation with the 3 Chinese characters were found in the anterior region(375-475 ms),posterior region(195-255 ms),and whole scalp region(135-175 ms and 275-355 ms).There were no significant interactive effects between schematic facial recognition and stimulation with Chinese characters.Conclusion Positive emotional excitement may promote the well-being of the adults in their health,intelligence,working performance and living.
