Startle reveals an absence of advance motor programming in a Go/No-go task

Presenting a startling stimulus in a simple reaction time (RT) task, can involuntarily trigger the pre-programmed response. However, this effect is not seen when the response is programmed following the imperative stimulus (IS) providing evidence that a startle can only trigger pre-programmed responses. In a "Go/No-go" (GNG) RT task the response may be programmed in advance of the IS because there exists only a single predetermined response. The purpose of the current investigation was to examine if startle could elicit a response in a GNG task. Participants completed a wrist extension task in response to a visual stimulus. A startling acoustic stimulus (124dB) was presented in both Go and No-go trials with Go probability manipulated between groups. The inclusion of a startle did not significantly speed RT and led to more response errors. This result is similar to that observed in a startled choice RT task, indicating that in a GNG task participants waited until the IS complete motor programming.
