人格因素及行为类型与应激——恢复期间皮电反应各参数间的相关性研究

The correlation between personality /behavior factors and parameters of Galvanic Skin Response during stress recovery period in university students

对１２名大学生被试的人格因素及行为类型与应激——恢复期间皮肤电反应（ＧＳＲ）参数的相关性研究显示，应激后ＧＳＲ恢复至基值所需时间以及３０分钟内ＧＳＲ最大值与Ａ型行为量表得分、ＥＰＱ的Ｎ维度得分及１６ＰＦ的Ｑ４因子得分有显著或极显著正相关（ｒ＞α０．０５或ｒ＞α０．０１），与１６ＰＦ的Ｃ因子有显著或极显著负相关（－ｒ＞α０．０５或－ｒ＞α０．０１）；而ＧＳＲ的基值水平、应激时ＧＳＲ的最高值等参数与上述人格／行为因素无明显相关。经过ＧＳＲ生物反馈训练后，上述相关系一般有所减弱。这一结果揭示，所谓“高生物反应者”，主要表现为应激后兴奋难以消退，而不是交感神经的基础兴奋性或应激时的绝对紧张度高于常人。经过ＧＳＲ生物反馈训练，这类被试虽仍具有上述特征，但程度有所减弱，提示他们对交感神经的自控能力的提高可能比一般人更加明显。

Correlation study between personality/behavior factors and galvanic skin response(GSR)was performed in 12 university students.The results showed that some GSR parameters,especially recovery time of GSR from minimal during stress back to baseline and the maximal value of GSR during 30 minutes relaxation after stress,had significant positive correlation(r>α 0 05 or r>α 0 01 )with scores of Type A Behavior Test,N score of EPQ and Q 4 score of 16PF,and significant negative correlation(-r>α 0 05 or-r>α 0 01 )with C score of 16PF.Meanwhile,the baseline and minimum of GSR (just occurred at the time of maximal stress)had no significant correlation with any personality /behavior factor.After GSR biofeedback training,these correlation still existed but generally weakened.These results suggest that the so called“high physiological responder”labeled by type A behavior tendency,high N score of EPQ and high Q 4 or low C score of 16PF have neither higher GSR baseline nor higher“responsibility”during short term stress than ordinary person,but they need more relaxation time to recover after confronting stress.
