摘　　要：本文旨在探讨内、外倾者在三种不同强度痛觉刺激下心率、T波幅度的变化。通过艾森克个性问卷筛选出15名内倾者和15名外倾者,以8mA、12mA、16mA的电流引起痛觉。实验结果表明,刺激后30秒内,在12mA、16mA痛觉刺激下,内倾组心率反应值与基础值差异显著,外倾组差异不显著;在12mA刺激下,内、外倾组心率变化差异显著。从心率变化上看,两组被试对痛觉刺激均表现出适应,内倾组的适应速度比外倾组慢。在各强度痛觉刺激条件下,二组T波幅度均未随刺激量增大发生显著变化。本实验表明,心脏T波幅度对痛刺激不敏感。This paper is to discuss the changes of heart rate,T-wave amplitude between the introverts and the extroverts when they receive different intensities of pain. 15 introverts and 15 extroverts screened according to the Eysenck Personality Qustionaire were divided into two groups of subjects. The sense of pain was produced by 8mA、 12mA、 16mA electric current. The results of this experiment show that under 12mA. 16mA stimuli,in thirty minutes, the reaction scroce and baseline differentce of introverts' heart rate reaction was significant;the extroverts' was insignificant. Under 12mA pain stimuli,the difference of the two groups' heart rate was significant.The heart rate changes of the two groups showed adaption to the sense of pain;and the introverts'adapting speed was slower than the extroverts' .The T-wave amplitude of the two groups didn't decrease significantly with the increase of intensity and was not sensitive to pain stimuli.
