Imagery, in today"s world of sport psychology, is as vital and fundamental a part of an athlete"s mental game plan as the physical training required for conditioning. With a widespread embrace of such a philosophy comes new ways to analyze and measure its performance among athletes. In "The Sport Imagery Questionnaire: Test Manual", the authors assess athletes" use of imagery by proposing and outlining a specifically designed evaluation of its effectiveness, the Sport Imagery Questionnaire (SIQ). The manual is designed for sport psychologists, coaches, athletes, or anyone who seeks to understand or quantify the use of mental imagery in sport. It features: a 4-page reproduction of the Sport Imagery Questionnaire in an easy-to-photocopy format, complete with instructions and specific rating chart; a "Scoring the SIQ" section to calculate imagery performance; a brief overview of the SIQ clearly and explicitly outlining its purpose and function; and 3 comprehensive chapters dedicated to understanding imagery, explaining the methods involved in both developing and successfully utilizing the SIQ, and the psychometric properties and normative data of the questionnaire itself.
