心算应激与特质焦虑、应对风格的关系

THE RELATIONSHIP AMONG MENTAL ARITHMETIC STRESS,TRAIT ANXIETY AND COPING STYLE

选取38名大学生为被试,采用BIOPAC多导生理记录仪,探讨心算应激对不同人格特质和应对风格的大学生心率(HR)、心率变异性(HRV)及皮肤电反应(GSR)的影响。实验采取2(人格特质:特质焦虑、非特质焦虑)×2(应对风格:注重情绪的应对、注重问题的应对)×3(实验阶段:基线期、任务期、恢复期)的三因素混合设计,要求所有被试经历5分钟的基线期、10分钟的心算任务期和5分钟的恢复期。结果表明:(1)特质焦虑的个体和注重情绪应对的个体在心算应激后的短时间内难以恢复到基线期的生理水平;(2)特质焦虑且注重情绪应对的个体在HR、HF、LF/HF及GSR上表现出明显强的反应性和弱的恢复性;(3)非特质焦虑且注重问题应对的个体在HF和GSR上表现出明显弱的反应性,在LF/HF和GSR上表现出明显强的恢复性。

The BIOPAC MP150 Systems was used to explore the effect of mental arithmetic stress on Heart Rate （HR） , Heart Rate Variability （HRV） and Galvanic Skin Response （GSR） in different personality trait and coping style undergraduates. There were 38 undergraduates as participants. The experiment was a mixed design： 2 （trait anxiety or not）×2 （situation-focused coping or emotion-focused coping）×3 （baseline, task or recovery） . All participants experienced 5 minutes baseline, 10 minutes mental arithmetic and 5 minutes recovery. The results showed： 1） During the short time after mental arithmetic, it was difficult for trait anxiety undergraduates or emotion-focused coping undergraduates to return to the baseline in physiological reactions; 2） Trait anxiety and emotion-focused coping undergraduates displayed higher responsivity and weaker recovery in HR, HF, LF/HF and GSR; 3） None-trait anxiety and situation-focused coping undergraduates displayed lower responsivity in HF and GSR, and displayed higher recovery in LF/HF and GSR.
