Schema theory: a critical appraisal and reevaluation

Area of Science:

• Motor control and learning
• Cognitive psychology
• Human movement science

Background:

• Schema theory, proposed by R. A. Schmidt in 1975, offers constructs and predictions for motor learning.
• Existing motor program theories and schema theory face critiques regarding their explanatory power for motor control and learning.
• Consistent findings in motor learning research need to be reconciled with theoretical advancements.

Purpose of the Study:

• Critically review the constructs and predictions of schema theory.
• Propose essential components for new motor control and learning theories.
• Ensure new theories account for established empirical findings in motor learning.

Main Methods:

• Critical literature review of schema theory and motor program concepts.
• Theoretical analysis of existing predictions and empirical findings.
• Formulation of requirements for advanced motor learning theories.

Main Results:

• Schema theory's constructs and predictions require critical re-evaluation.
• New theories necessitate a reformulated generalized motor program concept.
• Development of abstract movement structures through practice requires specific mechanisms.
• Parameter learning needs explanations that incorporate variability scheduling.

Conclusions:

• Future motor control and learning theories must integrate reformulated generalized motor programs.
• Mechanisms for developing abstract movement structures based on proportional principles are essential.
• Explanations for parameter learning must account for the benefits and scheduling of variability.
• New theoretical frameworks should build upon, rather than discard, established findings in motor learning research.
