Answer:
- Juli-an Rotter
Explanation:
In the given case, Jack is attempting to direct the American Psychologist Juli-an Rotter's "Social learning theory" in order to ask Lacey for a date.
In this theory, Rotter explains that one can learn new social behaviors by observation, as well as, the review of the rewards or punishments that a specific behavior produces. Here also, Jack observes his previous behaviors and approaches that he had displayed and the rewards associated with them. Therefore, he learns about those behaviors that had worked successfully for him, and hence, he decided to use them only to approach Lacey in order to get the expected reward.
