| Popis: | 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 arm movements (AM), saccadic eye movements (SM) or button presses (BP). The task was to intercept a moving target at a designated zone (i. e. no spatial error) either with the hand sliding a pen on a graphics tablet (AM), a saccade (SM) or a button press (BP) that released a cursor moving ballistically for a fixed time of 330 ms. The dependency of the final temporal error on action onset varied from "low" in AM (due to possible online corrections) to "very high" in the other conditions (i.e. open loop). The lag-1 cross-correlation between action onset and the previous temporal error were close to zero in all conditions suggesting that people minimized temporal variability of the final errors across trials. Interestingly, in conditions SM and BP, action onset did not depend on the previous temporal error. However, this dependency was clearly modulated by the movement time in the AM condition: faster movements depended less on the previous actual temporal error. An analysis using a Kalman filter confirmed that people in SM, BP and AM involving fast movements used the prediction error (i.e. intended action onset minus actual action onset) for next trial correction rather than the final target error. A closer look at the AM condition revealed that both error signals were used and that the contribution of each signal follows different patterns with movement time: as movement progresses the reliance on the prediction error decreases non-linearly and that on the final error increases linearly. |
