Fig 1. The standard and non-standard visuomotor mapping conditions.

In both conditions participants were required to fixate on and touch the central target during the cue and delay periods. The central target turned from white to red to indicate the go signal for movement initiation. At this signal participants saccaded to and slid their finger on the touch screen to the cued target location in the Standard condition. In the Non-Standard condition participants also saccaded to the cued target location but slid their hand to the opposite target. Note that the conditions were the same for both Experiment 1 (fMRI) and Experiment 2 (behavioural) but in the second experiment the delay period was decreased from 10 seconds to a variable delay of 1.5 +/- 0.5 seconds.
