Key Concepts

Motor Programming Theories

Motor programming theories propose that movements are executed using pre-stored motor programs. However, these theories faced challenges when trying to explain how each specific movement could be stored given the nearly infinite number of possible variations, and how these rigid programs could adapt to different environmental demands or task constraints.

Schema Theory

Schema theory offers a solution by suggesting that instead of storing individual motor programs for every possible movement, the nervous system develops generalized rules or schemas based on previous experiences. These schemas can be applied flexibly, allowing for the adjustment of parameters to accommodate variations in movement conditions.

Specificity and Storage Problems

Previous motor programming theories encountered two main problems: the specificity problem, which required an individual motor program for every unique movement, and the storage problem, which made it impractical for the nervous system to store an infinite number of specific motor programs. Schema theory addresses both by emphasizing general rules that can generate appropriate responses without the need for exhaustive pre-programming.
