Experimental configurations. A and B: start point(s) and possible target locations (30° arcs) in experiment 1 (A), in which auditory cues indicated which of two targets to reach to, and experiments 2 and 3 (B), in which cues indicated the response hand. C: timing for the two cueing conditions. In these examples, the cue indicates a movement to the left target or with the left hand, respectively. In the early cue condition, this information is provided at the time of the first tone (and coincides with the target onset in experiments 1 and 2 and the target presented early condition in experiment 3). In the late cue condition, this information is only provided at the onset of the imperative. In the target presented late condition in experiment 3, the target was presented at the same time as the imperative.
