During a cue-distractor task, participants repeatedly produce syllables prompted by visual cues. Distractor syllables are presented to participants via headphones 150 ms after the visual cue (before any response). The task has been used to demonstrate perceptuomotor integration effects (perception effects on production): response times (RTs) speed up as the distractor shares more phonetic properties with the response. Here it is demonstrated that perceptuomotor integration is not limited to RTs. Voice Onset Times (VOTs) of the distractor syllables were systematically varied and their impact on responses was measured. Results demonstrate trial-specific convergence of response syllables to VOT values of distractor syllables.
在一项线索干扰任务中,参与者根据视觉线索反复发出音节。干扰音节通过耳机在视觉线索出现后150毫秒呈现给参与者(在任何反应之前)。该任务已被用于证明感知运动整合效应(感知对产生的影响):随着干扰项与反应共享更多语音属性,反应时间(RTs)会加快。这里表明,感知运动整合不仅限于反应时间。干扰音节的语音起始时间(VOTs)被系统地改变,并测量了它们对反应的影响。结果表明,反应音节在特定试验中会趋向于干扰音节VOT值。
