What does Schmidt's schema theory propose?

• A. Fixed motor programs for each task
• B. Open-loop control only
• C. Generalized motor programs with recall and recognition schemas
• D. Sole reliance on sensory feedback

Answer: (C)

Movements are controlled by generalized motor programs that can be tailored to the situation through recall and recognition schemas. Instead of storing a single fixed pattern for every task, the system uses a generalized program as a template for a class of actions (for example, a throwing pattern). The recall schema selects the specific parameters to apply this template in a given context—initial conditions, speed, force, duration, and other task-specific variables—so you can adapt the same template to different distances, speeds, or starting positions. The recognition schema then checks the outcome by comparing the intended sensory consequences with what actually happens, producing feedback that helps adjust future performances. This framework explains how you can vary a skill across situations yet still rely on a consistent underlying plan, while still using feedback to refine the movement. This differs from fixed motor programs, which imply one exact pattern for a task and little flexibility. It also goes beyond open-loop control, which ignores ongoing adjustments based on feedback, and from a view that depends only on sensory feedback, which misses the planning and parameterization provided by recall and recognition schemas.
