This study examined the effect of various imagery modalities on golf putting performance. Forty experienced male golfers were randomly assigned to one of four groups. A “written script” group received a personalized, response proposition-laden script. Participants in the audio and video groups either listened to an audiotape or watched an internal-perspective videotape of themselves putting. Control participants spent an equivalent amount of time reading golf literature. Each participant completed a 15-ball putting task twice a week for 6 weeks and also performed his imagery or reading daily during this period. Pretests revealed no significant differences in performance. Posttests, however, showed that the video and audio groups performed significantly better than the written script and control groups. This indicates that the form in which an imagery intervention is delivered can have a significant impact on its performance effectiveness.
