Figures & data
Figure 1. Illustration of the trial sequence in the visuomotor task. Participants tracked the path of a black ball (with a 50 pixels radius, moving with a speed of 5 pixels per 16 milliseconds) that “bounced” around a 1366 cm cm wide by 768 cm long screen. Whenever the ball reached either the top, bottom, left or right corners of the screen, this was marked as a trial, and it would bounce back toward the opposite direction. Neither the ball nor participants’ movements left a trail. In 1 out of 10 trials, the ball would turn red (e.g., bottom middle panel) and remain still for one second. During this time, participants had to click on the red “oddball” as quickly and accurately as possible.
