Mechanisms for action prediction operate differently in observers with motor experience

摘要: Recent theoretical and empirical work has suggested an important role for the motor system in generating predictions about timing of external events. We tested hypothesis that experience with observed action changes how observers generated these actions by comparing performance naive experienced on a task required participants to predict particular critical points ongoing action. Crucially, we employed non-action stimuli identical temporal dynamics, predicted would enhance prediction accuracy specifically have reduced or negligible effect enhancing stimuli. Our results showed did modulate relative No difference between conditions was observers.
