Document Summary

We have embedded knowledge that helps us to predict what"s going to happen. Pre-structured set of motor commands chosen bycns pns. Keele 1968: set of muscle commands structured before sequence begins, allows the entire thing to happen without peripheral feedback. Brain can compute parameters and just do it. Open loop: sensory feedback during is not necessary. Memory representation of class of actions that share invariant characteristics basis for controlling specific action within class of actions. When you have a movement, you have constraints modify behavior. Invariant: unique set of characteristics that defines gmp, does not change between one action and another. Parameters: features of gmp that change from one performance/action to another, features of a skill that must be added to invariant features before person can perform a skill (8*2)+1 (10*2) + 1 (5*2) +1. These are all a specific motor program. But can be simplified to (mk *2) +1.
