The present study examined the facilitation effects of an auditory accessory stimulus that was irrelevant to a visual reaction time (RT) task as a function of stimulus onset asynchrony between the accessory stimulus and the visual target stimulus. Results of the present experiment showed that the auditory accessory stimulus caused two variations of RT, short-term and long-term, that were distinguished on the basis of stimulus onset asynchrony. This finding suggested that effects of an accessory stimulus consisted of two qualitatively different facilitations. The Transient Facilitation appeared instantly after the onset of the accessory stimulus and then soon decayed, and the Sustained Facilitation increased and decreased more gradually than the former.
本研究考察了与视觉反应时（RT）任务无关的听觉辅助刺激的促进作用，该作用是辅助刺激与视觉目标刺激之间刺激起始异步性的函数。本实验结果表明，听觉辅助刺激导致了反应时的两种变化，即短期变化和长期变化，这两种变化是根据刺激起始异步性来区分的。这一发现表明，辅助刺激的作用由两种性质不同的促进作用组成。瞬态促进作用在辅助刺激开始后立即出现，然后很快衰减，而持续促进作用比前者增加和减少得更缓慢。
