Moreover, velocity and acceleration of feedforward movements such as reaching are highly proportional to the distance of the target. Movement is possible even without feedback from the moving limb.Reaction time (time between “go” signal and movement initiation) increases with movement complexity, suggesting that movements are planned in advance.Processing of afferent information (feedback) is too slow for on-going regulation of rapid movements.Evidence for the concept of motor programs include the following: p. 182 P. 182 Signals transmitted through and pathways allow the central nervous system to anticipate, plan or guide movement. Quick reflexive decisions need to be made at every turn.Ī motor program is an abstract representation of movement that centrally organizes and controls the many involved in performing an action.
