Predictive Processing in Motor Cognition

What is Predictive Processing in Motor Cognition?
Predictive processing in motor cognition models how the brain employs forward models to anticipate sensory consequences of actions using efference copies and error signals for agency attribution.
This framework explains phenomena like intentional binding, where actions and effects are perceived closer in time, and sensory attenuation, where self-generated stimuli feel less intense (Hughes et al., 2012, 375 citations). It integrates motor control with sense of agency, showing deficits in disorders like schizophrenia (Voss et al., 2010, 360 citations). Over 10 key papers from 2010-2021 explore these mechanisms, with 100-375 citations each.
Why It Matters
Predictive processing unifies motor control, perception, and agency, explaining impaired action awareness in schizophrenia where patients fail to predict consequences (Voss et al., 2010). It informs computational psychiatry by modeling cerebellar roles in agency via forward models (Welniarz et al., 2021). Frameworks like cue integration in intentional binding aid diagnostics for agency disorders (Wolpe et al., 2013). Applications extend to tool use and motor learning simulations.
Key Research Challenges
Distinguishing Prediction from Postdiction
Agency experience arises from interplay of predictive forward models and postdictive cues, complicating isolation of mechanisms (Synofzik et al., 2013). Studies show postdiction influences awareness retrospectively (Shimojo, 2014). Resolving their contributions requires precise temporal manipulations.
Implicit vs Explicit Agency Measures
Implicit measures like intentional binding diverge from explicit ratings of agency, questioning their validity (Dewey and Knoblich, 2014). This dissociation challenges unified models of sense of agency. Calibration across methods remains unresolved.
Motor Prediction in Clinical Deficits
Schizophrenia patients show specific forward model failures in action prediction, not sensory processing (Voss et al., 2010). Cerebellar forward models link to agency disorders (Welniarz et al., 2021). Translating to diagnostics needs refined assays.
