Fig 2. Setup and procedure.

A) Experimental setup. B) time course of one single trial. Participants initiated the trial by tapping at the starting point after which a target was shown. The trial ended when the participant tapped on the tablet again at the end of their pointing movement, upon which the visual feedback was shown. C) Use of cued mappings. In Experiment 1, two mappings were trained. The -75 mm mapping (i.e. in order to hit the target participants had to point 75 mm to the left of the target, corresponding to a 75 mm rightward shift of the feedback relative to the actual pointing location) was cued by a relatively spiky shape (ρ = 0.125). The second mapping of +75 mm was cued by an almost circular shape (ρ = 0.875). The left column shows an example in which the participant had not yet learned to use the cue. In the right example the participant has already learned the cued mapping and points to the right of the actual target location.
