Abstract

The performance of 25 subjects in three reaction tasks of different complexity was compared at different activation levels induced by five different work loads on a bicycle ergometer. Heart rate and blood pressure were used as indexes of activation. The results were in agreement with the Yerkes-Dodson law in that the optimal physiological activation level for rapid performance varied with the degree of task difficulty, relatively lower activation being more favorable the more difficult the task.

摘要

在自行车测力计上，通过五种不同工作负荷诱导出不同的激活水平，比较了25名受试者在三种不同复杂程度反应任务中的表现。心率和血压被用作激活指标。结果与耶基斯-多德森定律一致，即快速表现的最佳生理激活水平随任务难度程度而变化，任务越难，相对较低的激活越有利。
