Document Summary
To generalize skill to a di erent situations: ex: shortstop does not eld group balls with the same speci cations throughout a game, variability should be the focus of practice. Variable practice: variability in movement and context is a necessary ingredient for skill development, a learner should be able to generalize a skill to a variety of situations, variable practice enhances the development of the learners schema. Helps to select appropriate parameters for the task: skill acquisition is best achieved through the modi cation of constraints, force-producing task (shea and kohl 1991. Practice trials: constant practice group outperformed the variable practice group. Retentions test: opposite e ect: greater learning gains by variable practice group. Learning and performance: learning: a relatively permanent change in a person"s ability to execute a motor skill as a result of practice or experience, performance: a temporary expression of a skill.
