摘要： 本文对31名听力正常的健康人作了脑干听觉电反应(BSR)描记。21人在记录过程中让其心算乘法,其中16人还令其注意听刺激短声并概算其触发次数。观察到21名心算者的BSR中16人的BSRⅠ波振幅比安静时的减小,20人的BSR出现了一阳性大波,未观察到Ⅰ波振幅增大的。在听短声的16人中未见出现Ⅰ波振幅减小者,且其中4人反而出现了Ⅰ波振幅相对增大,结果表明,心算乘法对BSR有一定影响,分析认为一种是对感受器的负反馈控制,另一种是正反馈控制,而且前者占优势。

Abstract: The brain stem auditory responses (BSR) of 31 subjects with normalhearing were recorded. 21 were asked to calculate multiplication. 16 wereasked to listen attentively to clicks and also estimate trigering times simul-taneously by recording. In the calculating group, BSR of 16 subjects had adecreased amplitude of wave Ⅰ in comparison with that of the calm subjects.BSR of 20 subjects had a positive wave with a 10--14msec latency. Noincreased amplituds of wave Ⅰ was observed in this group. In the second group, no decreased amplitude of wave Ⅰ was observed. Onthe contrary, the amplitude of wave Ⅰ of 4 subjects increased. The resultsindicate that BSR are affected by psycho-loads, in which negative and positivefeedback to the receptors may play a role, the former being predominant.
