(a) Participants were seated and attached to a rotary motor aligned to the elbow joint. Visual feedback of current and target elbow position was provided on a LCD monitor. (b) A schematic representation of how the probability of receiving the proprioceptive GO cue following the WARNING cue was varied in each of the three temporal certainty conditions. The range of times between WARNING and GO cues is shown in parentheses. Participants performed all experimental conditions on separate days. (c) The testing protocol included voluntary reaches cued by a proprioceptive GO cue with high-intensity probe perturbations delivered in 20% of the trials to investigate the influence of certainty condition on the development and release of triggered responses. Probe perturbations were delivered at 50 ms before the WARNING cue and at 1000, 500, 150, and 0 ms before the GO cue.
