| 摘 要： | 时间知觉是人类的一项基本能力.日常生活经验表明时间知觉容易受到情绪的影响.但是在前人的研究中,这些影响往往伴随着主动注意和外显的运动反应.这里关注的是不伴随主动注意和外显运动反应的内隐时间知觉是否受到情绪面孔的影响.被试在主动完成一个由情绪面孔组成的视觉辨别任务的同时,被动地听一系列声音刺激.声音刺激的刺激启动异步时间(stimulus onset asynchrony,SOA)中,80%是标准SOA(800ms),20%是偏差SOA(400,600 ms).对频繁出现的标准SOA和偶尔出现的偏差SOA诱发的事件相关电位(event-related potential,ERP)进行记录.2个短的偏差SOA(400和600ms)引发了2个变化相关的ERP成分:失匹配负波(the mismatch negativity,MMN)和P3a.代表对无规律变化早期检测的MMN波幅受到了情绪面孔的影响.与愉快和中性面孔相比,恐惧面孔降低了MMN波幅.对于400ms偏差SOA,与恐惧面孔和中性面孔相比,愉快面孔增加了P3a波幅.该ERP研究提示听觉通道的内隐时间知觉受到情绪面孔的影响,恐惧面孔降低了内隐时间知觉的准确性.

| Abstract: | Time perception is a fundamental ability of human beings.Daily experience indicates that time perception is easy to be affected by emotion.However,the emotional influence was often accompanied by active attention and explicit motor response in previous studies.Here the question whether implicit time perception could be influenced by emotional faces is addressed.Observers actively completed a visual discrimination task of emotional faces(fearful,happy and neutral faces) while they passively listened to a seq... |
