This review argues that investigations of imagery effects in sports psychology literature have been unnecessarily restricted by conceptualizations of imagery in terms of just mental practice or of performance rehearsal. The paper describes the findings of sport psychology literature on the effects of imagery in performance and discusses some of the problems of existing research literature. Alternative imagery models for sport psychology are explored including A. Ahsen's (1971) triple code (ISM) model of imagery and P. J. Lang's (see record 1978-27897-001) information processing model of imagery. (PsycINFO Database Record
