摘要
目的 探讨内外倾者在 3种不同强度痛觉刺激下心率、呼吸频率的变化。方法 通过艾森克问卷筛选出 15名内倾者(内倾组)和 15名外倾者(外倾组),以 8mA、12mA、16mA的电流引起痛觉,记录不同强度痛觉刺激时两组被试的心率、呼吸频率的变化。结果 刺激后 2min内,两组心率变化量均随刺激强度不同有显著差异。内倾组心率均随刺激量增加而增加,外倾组在 8mA、12mA刺激下心率减慢(变化率分别为-1. 9%, -2. 4% ),在 16mA刺激下心率增加 (0. 9% )。内外倾组呼吸频率变化无统计学意义(P>0. 05)。结论 同等强度痛刺激下,内倾者生理承受力弱于外倾者。
ObjectiveTo discuss the changes of heart rate and respiratory frequency between the introverts and the extroverts.Method 15 introverts and 15 extroverts were screened according to the Eysenck Personality Questionaire and received different intensities of pain produced by 8mA,12mA,16mA electric current.ResultsThe two groups' heart rate have significant difference under different intensities of pain;the introverts’ heart rate increase in pace with the increase of pain,and the extrovert's heart rate decrease under 8mA,12mA,but increase under 16mA.ConclusionThe extroverts' physiological endurance is stronger than the introverts' under same intensities of pain stimuli.
