【摘要】：目的探索睡眠剥夺对个体情绪图片主观评估的影响。方法选取某高校43名本科生,随机分为睡眠剥夺组(n=23)和正常睡眠组(n=20),因正常睡眠组有2人未参加后测任务,1人前测数据丢失,故正常睡眠组最终纳入被试17人。睡眠剥夺组在前测结束后进行睡眠剥夺(22:00~次日08:00)。正常睡眠组不做干预。从国际情绪图片系统中选取正、中、负性图片共216张(前测108张,后测108张;每类图片36张),通过正负性情绪量表(PANAS)考察两组被试在前后2次测试中主观情绪的变化以及整晚睡眠剥夺对情绪图片主观评估的影响。结果睡眠剥夺对正性和负性情绪图片的评分没有明显影响,但对中性图片的愉悦度评分存在负性偏倚,睡眠剥夺组对中性图片的愉悦度评分前、后测差异有统计学意义(P0.01),而正常睡眠组前、后测差异无统计学意义(P=0.12);控制协变量主观情绪后,睡眠剥夺造成的对中性图片愉悦度评分上的负性偏倚依然存在;睡眠剥夺组被试对情绪图片的唤醒度评分大于正常睡眠组(P0.05)。结论睡眠在情绪评估过程中发挥着重要作用,睡眠剥夺可导致个体对中性刺激的评估发生负性偏倚。
[Abstract]:Objective to explore the effect of sleep deprivation on subjective assessment of individual emotional pictures.Methods 43 undergraduates in a university were randomly divided into sleep deprivation group (n = 23) and normal sleep group (n = 20). Because 2 normal sleep group did not take part in the post-test task and 1 person had lost pre-test data, 17 subjects were included in the normal sleep group.Sleep deprivation group was given sleep deprivation 22: 00 ~ 08: 00 the next day after the test.Normal sleep group did not intervene.A total of 216 positive, medium and negative images were selected from the international emotional picture system (108 pre-test and 108 post-test).The changes of subjective emotion and the effect of sleep deprivation on the subjective assessment of emotional images were investigated by using positive and negative emotion scale (PANASS) in each group of 36 pictures before and after two tests.Results Sleep deprivation had no significant effect on the scores of positive and negative emotional images, but there was a negative bias in the scores of the pleasurable degree of the neutral images.The posttest difference was statistically significant (P 0.01), but there was no significant difference before normal sleep group (P < 0. 12). After controlling the subjective emotion of covariable, the negative bias of sleep deprivation on the score of pleasure degree of neutral picture still existed.The arousal score of emotional pictures in sleep deprivation group was higher than that in normal sleep group (P 0.05).Conclusion Sleep plays an important role in the process of emotional evaluation. Sleep deprivation may lead to negative bias in the evaluation of neutral stimuli.
