HKIN 215 Lecture Notes - Lecture 18: Free Throw
Document Summary
Outline: practice variability, variable vs. constant practice, benefits, supportive evidence, blocked and random practice, contextual interference, contextual interference effect, practice specificity. This is the basis for the development of a set of rules for actions (schema) Looked at both transfer and retention tests, not just in skill acquisition: relates to an individual learning a skill > novice. Introducing practice variability is associated with increased error during practice. Less error during practice provides no advantage in a retention test. Less error during practice is disadvantageous in a transfer test. Think about having variable experiences in a practice session (context) This results in interference (random practice: perform multiple skills, high in random practice > better persistence and adaptability. Theories for the contextual interference effect: the elaboration hypothesis (shea & zimmy, 1983, random practice forces learner to engage in a variety of cognitive processing activi- ties.
