4/4 These behavioral observations support the predictions of an efficient coding model and contradict alternative explanations such as Bayesian models and repeated suppression models.

3/4 A stronger repulsive bias occurs when movements are made with the nondominant hand, and among individuals with higher motor variance compared to those with lower variance.

2/4 We found that these sequential effects are inherent to the movement process, rather than perception.

1/4 We showed two novel sequential effects in 5 center-out reaching tasks: 1. Current movement is repelled away from the direction of previous movements. 2. Movement variability increases as the direction of the current movement deviates more from that of the previous movement.

4/4 We conclude 1) Attention defines cues that establish the context for sensorimotor learning. 2) Implicit adaptation remains unaffected by cognitive resources.

3/4 However, attention influenced adaptation indirectly. When the attended stimuli changed across trials, learning significantly decreased. The same stimuli had no impact when participants ignored them.

2/4 Similarly, for divided attention, cognitive demands of a secondary task did not impact learning, highlighting the robustness of the implicit system.

1/4 For spatial attention, attending to feedback or not did not affect learning rates.

@Ella_Maru @PLOSCompBiol Hi Ella, thanks for your interest! We believe this implicit error correction operates through the long-term depression in the cerebellar cortex. Please see our recent preprint on the neural model of adaptation for details :)

3/3 Our new experiments using error clamp feedback further confirmed that any difference in the learning function is due to the nonlinear motor correction function. There is NO modulation of the learning rate in the implicit system.

2/3 Reanalysis of previous datasets confirmed that there the learning rate is NOT modulated by error consistency.

1/3 Prior studies found varied learning functions for different error variances. However, our models suggest this is fully explained by the non-linear correlation between error size and response and does NOT require learning rate modulations.
