Research examining imagery use by athletes is reviewed within the context of an applied model for sport. The model conceptualizes the sport situation, the type of imagery used, and imagery ability as factors that influence how imagery use can affect an athlete. Three broad categories of imagery effects are examined: (a) skill and strategy learning and performance, (b) cognitive modification, and (c) arousal and anxiety regulation. Recommendations are offered for the operationalization and measurement of constructs within the model, and suggestions are provided for how the model may guide future research and application.
