50 right-handed men were evaluated on right and left hand-grip strength, fatigue, and perseveration tasks and on a finger-tapping task. Subjects were tested in combined ambient sensory conditions of bright light and noise, bright light and quiet, dim light and noise, and dim light and quiet to provide an initial test of asymmetrical activation of the hemispheres. Analysis did not support the hypothesized asymmetry in activation. However, increased fatigue and perseveration were found using the left hand.
对50名右利手男性进行了右手和左手握力、疲劳及持续性任务以及手指敲击任务的评估。受试者在明亮光线与噪音、明亮光线与安静、昏暗光线与噪音、昏暗光线与安静的综合环境感觉条件下接受测试，以初步检验半球的不对称激活情况。分析不支持假设的激活不对称性。然而，发现使用左手时疲劳和持续性增加。
