Document Summary
The faster you do something, the less accurate you"ll be and vice-versa. As index of difficulty gets higher, your speed slows down. Governs spatial accuracy: an emphasis on speed negatively affects accuracy and vice versa. Does not govern temporal accuracy: improves when a performer moves faster or movement distance is decreased. Implications: during early stages of skill acquisition, de-emphasize accuracy: usually emphasize accuracy initially, high speed training (develops speed first and accuracy comes later) 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. Why: unpracticed 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, 2011) Greater performance when practice nondominant to dominant limb (senff & weigelt, Two possible reasons for loss of motivation: boredom, frustration.
