Document Summary
Degrees of freedom: independent elements that a ord abundant action possibilities. Coordination: process of organizing a system"s available degrees of freedom in an e cient movement pattern to achieve a goal. Degrees of freedom problem: how do we coordinate and control available degrees of freedom to produce a movement. Motor program: mechanism at the core of the command center-based construct. Abstract representation of a movement plan, stored in memory that contains all motor command required to do an action. Generalized motor program: represents a class of actions or pattern of movement that can be modi ed to yield various response outcomes. Invariant features: relatively xed form trial to trial and de ne the program. Relative timing has been seen as also being an invariant feature if the generalized motor program (ex. walking) Sequence of actions is the disruption of the order that results in a di erent. Relative force is the force used to execute a movement and sjould change proportionately.
