以往的研究表明，在简单反应时间（SRT）任务中，反应力随着刺激强度的增加而增加。这一结果与通常认为感知系统通过固定大小的点状go信号激活运动系统的观点相矛盾。一种详细的观点认为，go信号的大小取决于刺激强度，因此更强烈的刺激产生更强烈的反应。为了检验后一种假设，本实验操纵刺激的持续时间和强度。反应力随持续时间的增加而增加，甚至超过刺激持续时间不再影响SRT的临界值约60 ms。此外，增加刺激的持续时间也增加了力输出的持续时间。这些发现反驳了点状传递激活到运动系统的模型。某些连续模型和具有长时间go信号的可变输出模型提供了这些影响的可接受的解释。
Previous research indicates that response force increases with stimulus intensity in simple reaction time (SRT) tasks. This result contradicts the common view that the perceptual system activates the motor system via a punctate go signal of fixed size. An elaborated view assumes that the size of the go signal depends on stimulus intensity so that more intense stimuli yield more forceful responses. In order to examine the latter hypothesis, the present experiments manipulated stimulus duration as well as intensity. Response force increased with duration even beyond a critical value of about 60 ms at which stimulus duration no longer affected SRT. In addition, increasing the duration of a stimulus also increased the duration of force output. These findings argue against models with punctate transmission of activation to the motor system. Certain continuous models and variable output models with prolonged go signals provide acceptable accounts of these effects.
