In studying physiologic responses to behavioral stressors, there are two competing strategies. Laboratory studies offer greater experimental control but less provocation. Field studies provide poorer experimental control but potentially greater provocation. Despite these differences, comparison within subjects of neuroendocrine responses to these different settings has not been performed. We studied 11 healthy young men in the field during public speaking and in the laboratory during carefully controlled mental arithmetic calculations. There were marked differences in self-report and in plasma levels of catecholamines in the two settings.
在研究对行为应激源的生理反应时，有两种相互竞争的策略。实验室研究能提供更好的实验控制，但刺激性较小。现场研究的实验控制较差，但潜在刺激性更大。尽管存在这些差异，但尚未对受试者在这两种不同环境下的神经内分泌反应进行比较。我们对11名健康年轻男性进行了研究，一次是在公开演讲的现场，另一次是在实验室中进行精心控制的心算时。在这两种环境下，自我报告以及血浆儿茶酚胺水平都存在显著差异。
