罗跃嘉; 黄宇霞; 李新影; 李雪冰
Abstract为探讨情绪与认知的相互作用关系及其脑机制,建立了情境图片、面孔、汉字和声音四个系列组成的中国情感刺激材料库,并通过ERP实验对情绪与注意、工作记忆的关系以及特质焦虑者的认知特点进行了研究。结果发现:⑴负性情绪刺激在信息加工过程中至少在注意、评价及反应准备这几个阶段具有某种优先权,注意偏向也可在内隐任务下发生,负性刺激对注意资源不足具有某种补偿作用; ⑵威胁性视觉提示对其后的视觉加工具有调节作用,高焦虑个体对这类性刺激投入了更多的视觉加工资源,而且威胁性刺激对注意的影响可以跨通道进行,威胁性的视觉刺激可以影响触觉注意; ⑶在情绪对工作记忆的影响方面,负性情绪下空间工作记忆任务引起的P300波幅减小,这种效应可能是基于情绪对顶叶注意系统的调节作用,而在词语工作记忆任务中这种效应消失。
