It was hypothesized that subjects who used mental imagery would spend more time practicing a golf putting task and would have higher task specific self-efficacy than control subjects. Thirty-nine absolute beginner golfers were randomly assigned to either an imagery treatment condition (performance plus outcome imagery or performance imagery) or a no imagery (control) condition. During the first three sessions all subjects were taught how to putt a golf ball. Imagery treatment subjects also participated in an imagery training program designed specifically for the golf putting task. For the final three sessions, subjects were told that the emphasis of the study was on performance. Subjects in the performance imagery group spent significantly more time practicing the golf putting task than subjects in the control group. Subjects who used imagery also set higher goals for themselves, had more realistic self-expectations, and adhered more to their training programs outside of the laboratory.
