【摘要】：对于个体而言,自我有着重要意义,具有独特的情感含义。在知觉层面个体对自我信息加工存在偏向。有研究者提出情绪会影响个体的自我信息知觉加工偏向,但是关于情绪是如何影响自我信息知觉加工偏向的,目前尚未明晰,本研究从情绪二维度理论入手,通过分离情绪的唤醒度(arouse)与效价(valence)研究情绪对自我信息知觉加工偏向的作用机制。实验一考察在知觉匹配任务中情绪对自我信息知觉加工偏向的作用机制。根据情绪二维度理论选取焦虑、抑郁、宁静、高兴四种情绪。通过比较在高唤醒水平(高兴,焦虑)和低唤醒水平(宁静,抑郁)两组情绪状态下个体自我信息知觉加工偏向来分离唤醒度这一维度,比较在正性效价(宁静、高兴)和负性效价(焦虑、抑郁)两组情绪状态下个体自我信息知觉加工偏向来分离效价这一维度。通过有效分离情绪的效价和唤醒度发现,当个体处于低唤醒水平的情绪状态下个体的自我信息知觉加工偏向削弱甚至消失。实验二考察在知觉辨认任务中情绪对自我信息知觉加工偏向的影响,实验过程和实验一相同,最终结果表明低唤醒水平下的情绪状态,自我信息知觉加工偏向被削弱。说明情绪对自我信息知觉加工偏向的影响模式是一致的。实验三A实验三B固定情绪的效价强度,直接通过警觉信号操纵个体唤醒水平,进一步考察在知觉匹配和知觉辨认任务中情绪唤醒水平对自我信息知觉加工偏向的影响。发现高唤醒水平的情绪状态下,个体自我信息知觉加工偏向更显著,低唤醒水平的情绪状态下自我信息知觉加工偏向消失。综合以上研究,本研究主要发现:(1)无论是在知觉匹配任务中还是在知觉辨认任务中,情绪对自我信息知觉加工偏向的影响机制是一致的;(2)低唤醒水平的情绪状态下个体自我信息知觉加工偏向被削弱甚至消失,情绪是通过唤醒度对自我信息知觉加工偏向起调节作用。
[Abstract]:To the individual, the ego has important meaning, has the unique emotion meaning. In the perceptual level, the individual has the bias to the self-information processing. Some researchers have suggested that the emotion will affect the individual's self-information perception processing bias. However, it is not clear how emotion affects the processing bias of self-information perception. This study starts with the theory of two dimensions of emotion. The mechanism of emotion's processing bias to self-information perception was studied by separating the arousal degree of emotion and valence. Experiment 1 examined the mechanism of emotion's processing bias to self-information perception in the task of perceptual matching. Emotion Two-Dimensional Theory of choosing anxiety, Depression, tranquility, and happiness. By comparing the processing bias of individual self-information perception in the emotional state of high arousal (pleasure, anxiety) and low arousal (tranquility, depression), we separated the dimension of arousal. To compare the dimensions of positive titer (tranquility, happiness) and negative titer (anxiety, depression) to separate the titer of individual self-information perception processing bias, which was found by effectively separating the titer and arousal of emotion. When the individual is in a low arousal level of emotion, the processing bias of the individual's self-information perception is weakened or even disappeared. Experiment 2 examines the effect of emotion on the processing bias of self-information perception in the perceptual recognition task, and the process of the experiment is the same as that of experiment 1. The final results show that the emotional state at low arousal level and the processing bias of self-information perception are weakened. It shows that the influence of emotion on the processing bias of self-information perception is consistent. The titer intensity of fixed emotion in experiment three A and experiment III B is the same. By directly manipulating individual arousal level by alert signal, we further investigate the effect of emotional arousal level on self-information perception processing bias in perceptual matching and perceptual recognition tasks. It is found that under the emotional state of high arousal level, The processing bias of individual self-information perception is more significant, and the self-information perception processing bias disappears under the emotional state of low arousal level. Synthesizing the above research, this study mainly found that: 1) whether in the task of perception matching or in the task of perceptual identification, The influence of emotion on the processing bias of self-information perception is consistent with that of self-information perception. (2) under the emotional state of low arousal level, the processing bias of individual self-information perception is weakened or even disappeared. Emotion regulates the processing of self-information perception by arousal.
