Question 2
Two Olympic hopefuls are practicing for a big competition. To practice his jumps for the event, Guy spends an entire practice session working on each of the jumpsone practice session per day for each of the six types of jumps.
His competitor, Gary, divides each of his jump practices into six time periods, practicing each jump every practice day. Assuming they end up spending the same amount of time practicing jumps, which skater is likely to benefit most from practice, and why?
a) Gary, because he will take advantage of distributed practic
b) Guy, because he will take advantage of massed practice
c) Gary, because he will spend more time in his region of proximal learning
d) Guy, because he is more likely to achieve overlearning
