Imagery, which can be used by anyone, is appealing to performers because it is executed individually and can be performed at anytime and anywhere. The breadth of the application of imagery is far reaching. Briefly, imagery is creating or recreating experiences in one’s mind. From the early theories of imagery (e.g., psychoneuromuscular) to the more recent imagery models (e.g., PETTLEP), understanding the way in which imagery works is essential to furthering our knowledge and developing strong research and intervention programs aimed at enhanced performance. The measurement of imagery ability and frequency provides a way of monitoring the progression of imagery use and imagery ability. Despite the individual differences known to impact imagery use (e.g., type of task, imagery perspective, imagery speed), imagery remains a key psychological skill integral to a performer’s success.
