Illustration of the stimuli during the experiment. A, Depiction of the baseline condition during which only a red fixation cross in a white frame was presented. B, During the STATIONARY condition, nine static bars were presented in addition to the baseline stimuli. C, Stimuli of the other two conditions were identical, where the bars moved in either of two directions (left or right). During FIX-MOVING, participants were instructed to just fixate the red cross in the middle of the screen. Contrariwise, subjects had to watch out for changing velocity of the moving bars during the ATTEND-MOVING condition.
