摘要
目的 :研究大学生长潜伏期听觉诱发电位与感觉寻求人格特征的相关性。方法 :对 79名大学生进行感觉寻求人格测试 ,并采用 70、80、90、10 0dB 4种短纯音刺激检测其长潜伏期听觉诱发电位。结果 :大学生具有较为突出的去抑制人格特征 ;Cz、C3、C4 部位N1、P2潜伏期随刺激强度的增加而缩短 ;N1、P2以及N1 P2波幅随刺激强度的增加而增加 ;高感觉寻求者Cz、C3、C4 部位 2 0min后再测的波幅 刺激强度函数 (ASF)斜率明显减小 ,与首次测试相比差异具有显著意义。结论 :长潜伏期听觉诱发电位的强度依赖性及快速习惯化现象 。
Objective: To study the correlativity of long latency auditory evoked potential and sensation seeking personality trait in college students. Methods: Seventy-nine college students were assessed with sensation seeking scale. Long latency auditory evoked potential was determined by tones stimulation at 4 different intensities of 70,80,90,100 dB Results:The college students showed more significant disinhibition personality trait.The N1,P2 latency at Cz,C3,C4 decreased with the increace of stimulation intensity,while,N1,P2,N1/P2 amplitudes increased with the increase of the stimulus intensity.The ASF slope of high sensation seekers significantly decreased at Cz,C3,C4 20 minutes after the first determination.A significant difference was noted as compared with that in the first time determination.Conclusion:Intensity dependence and fast habituation of long latency auditory evoked potential might be electroneurophysiological marker of sensation seeking personality trait.
