Each task consisted of an implicit probabilistic learning and a test phase. To fill this gap, we measured behavioral (Experiment 1) and motor responses (Experiment 2) during two tasks requiring the prediction of occluded actions or geometrical shapes.

However, it is still unclear how newly learned action-context associations can drive our perception and motor responses. N2 - In everyday-life scenarios, prior expectations provided by the context in which actions are embedded support action prediction. T1 - Contextual Priors Guide Perception and Motor Responses to Observed Actions These findings suggest that contextual priors can shape motor responses to action observation beyond mere kinematics mapping.', Particularly, in conditions of perceptual uncertainty the motor system coded for the most probable action based on contextual informativeness, regardless of action kinematics. Importantly, motor responses were modulated by contextual probability during action, but not shape prediction. Results showed that reliable contextual cues made participants more accurate in identifying the unfolding action or shape. During the test phase, videos were earlier occluded to reduce the amount of sensorial information and induce participants to use the implicitly learned action/shape-context associations for disambiguation. During learning, we exposed participants to videos showing specific associations between a contextual cue and a particular action or shape.
