Male and female university students, classified as Type A and Type B persons with the aid of a questionnaire measuring coronary-prone behavior, were studied while doing mental work under laboratory conditions, characterized by understimulation and overstimulation, and while unoccupied (baseline session). The urinary excretion of adrenaline, noradrenaline and cortisol, heart rate (in the understimulation and baseline conditions) and self-reports were used as indices of arousal. The overall picture showed that both experimental conditions increased arousal, the rise being particularly pronounced for cortisol excretion during understimulation and for adrenaline excretion during overstimulation. Comparison between groups showed that cortisol excretion was higher in Type A than in Type B persons of both sexes during understimulation. Adrenaline excretion was about the same in both sexes (Type A and Type B) during understimulation, but was higher in males than in females during overstimulation. There were no group differences in performance.
借助一份测量冠心病倾向行为的问卷，将男女大学生分为A型和B型，在实验室条件下对他们进行研究。实验室条件分为刺激不足和刺激过度两种情况，同时设置了无任务状态（基线期）。将肾上腺素、去甲肾上腺素和皮质醇的尿排泄量、心率（在刺激不足和基线状态下）以及自我报告作为唤醒指标。总体情况表明，两种实验条件均会增加唤醒水平，在刺激不足时皮质醇排泄量的增加尤为明显，在刺激过度时肾上腺素排泄量的增加尤为明显。组间比较显示，在刺激不足时，男女A型人群的皮质醇排泄量均高于B型人群。在刺激不足时，男女（A型和B型）的肾上腺素排泄量大致相同，但在刺激过度时，男性的肾上腺素排泄量高于女性。在表现方面不存在组间差异。
