Document Summary
Elite athletes can dominate and international level b/c of sensory and motor abilities. Experimental method: characterizes affect of a variable on the behaviour of people in general. Manipulate the speed and a of mvt to determine how they impact movement accuracy. Differences in motor behaviour b/w groups of people: Mean rt of elite athletes less than healthy population rt. Differential approach: determine how individual diff in mvt speed and a impact mvt accuracy; studies ability and prediction. Diff in motor performance reflect skill and ability. Ability genetically determined and largely unmodifiable by practice or experience (height) Skill countless in # and can be modified with practice (golf swing) Abilities: inherited traits, stable and enduring, #ed (maybe 50) and underlies diff skills. Skill: developed with practice, easily modifiable with practice, countless in #, depends on several abilities. High positive correlation between task a and b. General motor ability hypothesis: a person with strong general motor ability should perform.
