Some recent findings suggested that response force measured during reaction time experiments might reflect changes in activation. We performed an experiment in which the effect of sleep deprivation, knowledge of results, and stimulus quality on response force was studied in simple and choice reaction tasks. As expected, both simple and choice reaction times increased with sleep deficit. Further, simple and choice reactions were faster with knowledge of results and slowed down when stimulus quality was degraded. As sleep deprivation affects both arousal and activation, we expected a detrimental effect of sleep on force amplitude. On the other hand, knowledge of results was expected to increase force by its compensatory effect on arousal and activation. No effect of sleep deprivation on response force was found. Knowledge of results increased response force independently of sleep deprivation.
最近的一些研究结果表明，在反应时实验中测量的反应力可能反映激活的变化。我们进行了一项实验，研究了睡眠剥夺、结果知晓情况和刺激质量对简单反应任务和选择反应任务中反应力的影响。正如预期的那样，简单反应时和选择反应时都随着睡眠不足而增加。此外，有结果知晓时简单反应和选择反应更快，而当刺激质量下降时则变慢。由于睡眠剥夺会影响唤醒和激活，我们预计睡眠会对力量幅度产生不利影响。另一方面，结果知晓预计会通过其对唤醒和激活的补偿作用来增加力量。未发现睡眠剥夺对反应力有影响。结果知晓独立于睡眠剥夺增加了反应力。
