$$You recognize that GameStop's summer internship program for college students, to bring in and train possible store management candidates who have a recent, working knowledge of the kinds of games you're trying to sell, has not been achieving the performance results desired due to lack of motivation. Many of the recent interns lacked motivation because of near$-$impossible performance targets and rewards they do not value. You decide to tell intern supervisors about a motivation theory in which for interns to be motivated, if they put forth the effort to work hard this will lead to performance at the desired level, and if they work at that level they will be rewarded, and that those rewards will be important to them. What motivation theory does this demonstrate?
