摘　　要：目的:通过听觉事件相关电位研究男性性反应的注意力变化。方法:对广告招募的30名成年男性,用主观性唤起多元评价指标测查其聆听性感听觉材料后的主观性反应状态;应用Brain-Product公司生产的BP-ERP工作站研究被试在放松和主观性反应状态中的听觉事件相关电位,分析大脑前额叶各电极点P3潜伏期与波幅特点,分析被试报告odd-ball范式中靶刺激次数的正确率。结果:主观性唤起多元评价指标显示被试听性感听觉材料后达到轻-中度主观性唤起水平;男性在主观性反应状态中多导联P3潜伏期长于放松状态(P<0.05),两者波幅的差异无统计学意义(P>0.05);主观性反应状态中被试报告odd-ball范式中靶刺激次数的正确率低于放松状态(P<0.05)。结论:在主观性反应中男性可能仍对外界保持一定程度的有意注意。Objective： To study the attention changing of male when they are in sexual response through the auditory event related potential （AERP） research. Methods： Thirty males were enrolled and assessed with the Multiple Indicators of Subjective Sexual Arousal when listening to the sexual auditory material. The AERP was noted and analyzed by Brain-Product BP-ERP workstation when they were in relax and sexual response state. The numbers of odd-ball target stimulation they had heard were noted. Result： The result of Multiple Indicators of Subjective Sexual Arousal showed that males were in low-moderate subjective sexual response state. P3 latencies were significantly longer in sexual auditory material [（447.49 ±72. 79） ms vs. （417.18 ±53.12） ms, P 〈0. 05] than in relax music, and the amplitudes between these two backgrounds were no significant differences （P 〉 0. 05）. Males＇accuracy rate of the number in the odd-ball target stimulation was lower in subjective sexual response state [ （95.3 ± 3.1） % vs. （91.4±2. 6） %, P 〈 0. 05]. Conclusion： In subjective sexual response state, male＇s deliberate attention toward outside may be maintained to a certain extent.
