摘要： 本工作在尽量减少其它对注意过程可能发生影响的心理因素的实验条件下,于同一组被试同时研究了选择性注意与实验次序对人体大脑听觉诱发电位晚成份的影响。观察到:选择性注意使N_1波与P_2波潜伏期延长,波幅增高;P_3波波幅增高。先试组N_1波潜伏期延长,波幅增高;P_2、N_2、P_3波波幅增高。实验中观察到一些不符合刺激强度规律的现象。对实验结果进行了讨论。

Abstract: In this experiment some psychological conditions were further controlled,the effects of the selective attention and the novelty of the environment andstimuli on the late components of auditory evoked potentials of the human brainwere studied simultaneously in the same group of subjects. The resultsindicated: During selective attention, wave N_1, P_2 latency increased andamplitude enhanced; wave P_3 amplitude enhanced. Novelty of the environmentand stimuli caused wave N_1 latency increase and amplitude enbance; wave P_2N_2 P_3 amplitude enhance. we observed some EP, in which the amplitude islarger when the stimulus is weak, the ampltude is smaller when the stimulusis stronger. The results were discussed.
