REM睡眠对再认和情绪性再认的影响
摘要:为探讨REM睡眠对情绪记忆的影响。让被试对随机呈现的66个正性、中性或负性情绪词汇(每种情绪词汇22个)进行学习,随后被试随机分成完全睡眠剥夺组、REM睡眠剥夺组、完全睡眠组,每组10名被试。经过3个小时的不同睡眠任务后,通过按键反应判断情绪词是否为旧词。发现不同的睡眠情况与词汇的情绪性之间不存在交互作用。睡眠剥夺特别是REM睡眠的剥夺的再认成绩显著低于完全睡眠组;词汇是否带有情绪性对再认成绩的影响不显著。

Abstract:To investigate effects of REM sleep deprivation on words about emotional memory. 30 young females were asked to study 66 words about positive ,neutral or negative emotion (22 words each emotion),than were randomly divided into three groups ,REM SD (sleep deprivation for REM), TSD(total sleep deprivation ), TD(total sleep), 10 females each group. After 3-hours sleep or sleep deprivation tasks, subjects were asked to recognize the old words by pressing the keyboard. The effect between sleep deprivation and emotional words was not marked. Results of recognition of words about emotional memory after REM SD and TSD was lower markedly than that after total sleep. The effect on emotional words was not marked.
