13、过大量实验证明，事件相关电位可以敏感地反映出情绪变化在脑内的活动过程，为人脑高级功能的研究提供了一种客观可行的方法，同时，事件相关电位也是评价大脑信息处理活动的一种无创伤性方法，被誉为“观察脑高级功能的窗口”。通过查阅众多相关文献和进行大量实验，本研究在脑电信号采集实验设计部分采用图片实验组和乐曲混合对照组进行实验对比，同时考虑到情绪类型的多样性以及诱发效应不同，对每个实验组分别进行三种不同情绪（愉快、悲伤、恐惧）的诱发实验。考虑到事件相关脑电是一种特殊的诱发电位，通常情况下幅值为几微伏，而自发脑电的幅值是其数十倍，通过直接采集的信号无法观察其波形。而且在采集到的脑电信号中混有大量伪迹和噪声，

14、对分析ERP特征带来了很大的困难，严重影响了分析结果的准确性。在ERP提取方面，本文提出了一个基于ICA和小波分析的脑电去伪迹、滤噪的方法。信号的主要处理过程为：首先采用FastICA算法对采集到的脑电信号进行分量分解，去除伪迹成分；对处理后数据进行数据分段，以段为单位提取每个靶刺激处脑电信号；再进行基线校准调整信号位置；将数据进行相干叠加，可以观察到ERP波形；为了使得到的ERP信号更清晰、直观，在考虑了滤波器等几种去噪的方法后，选择了去噪效果较好的小波方法进行滤波去噪，获取较清晰的ERP信号。XXXXXXXXXXXXXXXXXXXXXXX。关键词：事件相关电位；情绪感知；ERP提取；ICA

The research of EEG based on emotion perception has gradually become the focus in the field of emotional study. Af

17、s information processing activities. Therefore, The ERP is called “the window for advanced brain function observation”.By accessing to relevant documents and trying abundant experiments, a new experimental scheme for acquiring brain signals was proposed. The testees were divided into two groups (one

Considering the diversity of emotion type and the strength of emotions, we choose three different kinds of emotions (happiness, sadness and horrible) in each experimental group.Event-related EEG

19、 is a special evoked potential, whose amplitude is about several Micro-V. However, the amplitude of spontaneous EEG is over ten times larger than ERP. Thereby the ERP wave can not be directly observed in the raw signals. Usually there are a lot of noises and false tracks which mix in the raw EEG, in

20、 order to remove them, this paper propose an ERP extraction method based on ICA and wavelet to remove the false tracks. The whole procedure for signal processing is: Firstly, the FastICA algorithm is employed to decompose out the false track components. Then divided the data into epoch (according to

21、 the trial numbers), correcting the baseline of the signals and take congruence average, so that the ERP wave could appear. Finally, to get a clearer signal of ERP, the wavelet method is applied to filter noise.Comparing and concluding the processed the EEG signals from behavior record, rhythm wave,

When people are busy in cognizing process, the one who is in positive emotion has the lower accuracy and lower EEG active. However, its response is faster than those persons in negati

138、领域的科学家就开始对情绪进行了大量的研究。特别是近些年，情绪的脑机制1越来越多的受到国内外学者的关注，尽管研究者们通过大量实验探索，对情绪的心理机制及其影响有了一定了解，但科学界关于情绪的定义仍然存在一些争论。概括地说，情绪是人脑对客观现实是否满足自身需要的一种主观体验，涉及生理、心理及行为三个方面，它与其它心理过程（如认知、动机）有复杂的相互作用关系。正是由于情绪的这种复杂性，情绪研究一直是心理学研究中的难点。国内外的研究者主要从情绪的发展、分类、情绪对其它心理过程的影响及情绪的生理机制等方面进行研究。20世纪80年代以来，研究者开始对情绪智力（尤其是情绪调节方面）及情绪的无意识过程进行研究

139、，其中伴随着脑成像技术、遮蔽实验等新方法的运用。通过研究，许多心理学家相信，人总会潜意识地按照“积极高兴“和“消极不高兴”来评价周围环境。如果能通过脑电信号来识别人的情绪状态，就可以更有效的为心理疾病患者进行诊断，更准确的评定脑功能康复进展。同时，对情绪感知下脑活动的研究还可以为人们提供事物情绪性的评定，使人们能够选择接近那些被定义为积极的事物，并避免那些产生消极结果的事物，帮助人们缓解来自社会、家庭等方面的压力。XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
