基于脑电信号的心理分析系统的设计 (毕业设计37页、14126字+图+程序) 摘要:人类是思维的动物,每个人的喜怒哀乐都是心理活动变化的结果,而大脑是思维的主要器官,脑电信号最直接也最准确的反映了人的各种心理活动的变化。脑电图中包含了大量的信息,脑电波中包含着 、β波等不同频率和幅度的成分,不同频率的脑电波也表示着人不同的心理信息,比如人的智力水平高或低、焦虑或平静的状态,也或许是其他方面的信息。所以基于脑电信号与心理活动密切相关的特点,我们利用VB建立心理测试平台,同时使用RM6240C型多通道生理信号处理系统采集被测试者的脑电信号,通过以上两个方面对脑电信号进行分析,发现不同难度的测试题、测试的次数多少和时间长短等对人体心理的影响。这对于提高人们的心理素质有一定的帮助。 关键词:Visual Basic;MATLAB;心理分析系统;脑电图 Abstract: The human are the animals of thinking, each of them may be happy or angry because psychological activity in heart have changed. However the brain is a main organ of thinking, the brain waves reflect the change of human’s psychological activity mostly accurately and most directly. There are millions of information in EEG, which includes alpha, beta and many other different frequency band and magnitude electric waves, and the different ingredient brain waves are indicating the different information, such as the level of human’s intelligence, the quite or anxious state, and many other messages. Because EEG have great relationship with psychological activity, we use RM6240 to collect EEG waves while test the people in testing system, which is built by VB. Though the two systems we analysis data to find out the fact that the level of difficulty of test, the times of test and the last time make any effect on human’s psychology. This may be help to raise the mental character of people. Keyword: EEG, Visual Basic, MATLAB, Mentality Analysis System
