摘要
本研究以EPQ为依据选择高神经质和低神经质2组共24名被试,以有时间压力的心算和复杂辨别反应操作为紧张性刺激,在进行作业的同时记录被试的呼吸频率、呼吸流量、脉率、指端血管容积和皮肤电反应等五项生理指标,并检测尿内儿茶酚胺分泌量。通过对人格类型、作业成绩、作业难度主观评价、紧张性情绪体验,以及对尿内儿茶酚胺分泌量和五项生理指标的综合分析,以研究人格类型对应激反应影响的程度和途径。结果表明,在两组被试作业成绩无显著差异的情况下,在对作业难度主观评价和情绪体验的程度上,高神经质组高于低神经质组。在平静状态下,高神经质组去甲肾上腺素分泌量高于低神经质组;应激状态下,高神经质组的儿茶酚胺反应强度和变化幅度均明显高于低神经质组。高神经质组的五项生理指标均比低神经质组有较大的变化幅度。儿茶酚胺分泌量与脉率有明显的正相关。另外,通过与自然应激源部分的实验结果比较,发现实验室与现场应激的效果基本一致。
12 subjects with high neuroticism scores and 12 subjects with low Nscores were chosen by using Eysenck Personality Questionnaire and a complexchoicereaction task under time pressure. Urine catecholamine excretion,pulserate, breathing rate, breathing volume, galvanic skin response andsubjective psychological reactions were measured during and after the workperiod. The result showed large individual differences in the two groups.High N scores increased signifficantly at catecholamine excretion and fivephysiological indexes compared with low N scores, and high N scores hadgreater subjective psychological reactions. In the other hand, the resultalso showed signifficant positive correlation between catecholamine and pu-lse rate, When the result of the present experiment was compared withthe result got in section of natural stressor, same efficiency was foundbetween natrual stressor and laboratory stressor.
