Different ways for correcting for previous temporal errors in interception tasks



Correction on the basis of previous errors is paramount to sensorimotor learning. While corrections of spatial errors have been studied extensively, little is known about corrections of previous temporal errors. We tackled this problem in different conditions involving hand movements (HM), saccadic eye movements (SM) or button presses (BP). The task was to intercept a moving target (3 possible velocities) at a designated zone (i.e. no spatial error) either with the hand sliding a pen on a graphics tablet (HM), a saccade (SM) or a button press (BP) that released a cursor moving ballistically
