在三个实验中，其中的前脉冲的持续时间被操纵的人类惊吓眨眼反应的抑制进行了评估。在所有情况下，抑制惊吓更明显的前脉冲持续时间从6毫秒增加到50毫秒。单预脉冲的惊吓幅度的抑制没有显着不同的配对预脉冲（实验1），但抑制更明显的预脉冲强度增加（实验3）。改变前脉冲偏移酸启动刺激发作之间的间隔对抑制没有显着影响（实验2）。这些数据表明，惊吓抑制的敏感性，前脉冲持续时间，并建议该反应系统可以用来评估早期的时间总和在听觉系统。
The inhibition of the human startle eyeblink response was assessed in three experiments in which the duration of the prepulse was manipulated. In all cases, inhibition of startle was more pronounced as prepulse duration increased from 6 to 50 msec. Inhibition of startle amplitude for single prepulses was not significantly different from that for paired prepulses (Experiment 1), but inhibition was more pronounced as prepulse intensity increased (Experiment 3). Varying the interval between prepulse offset acid startle-stimulus onset had no significant effect on inhibition (Experiment 2). These data demonstrate the sensitivity of startle inhibition to prepulse duration, and suggest that this response system can be used to evaluate early temporal summation in the auditory system.
