Document Summary
Lecture 18 - chapter 8 - principles of practice design. The faster you do something, the less accurate you"ll be & vice-versa. As index of difficulty gets higher, speed slows down. An emphasis on speed negatively affects accuracy and vice versa. Improves when a performer moves faster or movement distance is decreased. It doesn"t matter how you get there, just how long it took you. Implications: during early stages of skill acquisition, de-emphasize accuracy. Ability to use both hands with equal proficiency is an advantage (sport and life) Practice with one limb enhances skill acquisition on the same task using the opposite limb. Non-practice limb uses same gmp as practiced limb (muscles are parameter) One limb acquires important cognitive info about movement problem and transfers to other limb. Greater degree of transfer occurs preferred to nonpreferred limb (magill) Greater performance when practice non-dominant to dominant limb (senff & weigelt) Two possible reasons for loss of motivation: boredom, frustration.
