The paper shows that sensory uncertainty affects motor learning differently in blocked vs interleaved trial contexts when both feedforward and feedback processes are engaged, with abrupt changes in movement plans correlated with sensory uncertainty.

The paper investigates whether sensory uncertainty drives abrupt changes in motor plans during movement or acts as a context cue for context-specific motor learning, finding that an aiming model better explains the data.

This study models how confidence judgments during visuomotor learning integrate recent error history and environmental volatility.

This study shows expert surgeons adapt and generalize better than naive controls in a visuomotor task, challenging the assumption of uniform motor learning across adults.
