PSYC 3260 Lecture Notes - Lecture 10: Ideomotor Apraxia, Bicycle Tire, Motor Program
Document Summary
Ppl were secretarial students who were skilled typists, but had not yet used word processors. Practice over 6 days, 3 hours/day editing a written manuscript containing 6 changes per page. Dependent variables: measured total time to make edits, thinking time: whenever more than 2 sec elapsed bw successive keystrokes, keystroke time: whenever less than 2 sec elapsed bw keystrokes. Results: most improvement is a result of reduction in thinking time, keystroke rate did not change substantially, in other words skill acquisition starts out with a large cognitive component that decreases with practice. Generalization: suggest that skill acquisition starts out with a large cognitive component that decreases with practice, w. enough practice the cog component of practice is squeezed out entirely and there is only an automated motor routine. Power law of learning: studies have investigated how memory improves with massive amounts of practice, pirolli & anderson (1985) Subjects practiced mem for 15 sentences for 25 days, 2 hours per day.
