Previsualization which can also be spelled as Pre-visualization refers to a method of mental rehearsal in which the athlete visualises performance before executing a move. Previsual isation can either be literally a picture, played like a movie in your head, or it can be an "internal" view of the activity, such as "feeling through" the shot beforehand. In archery for example, a complete visualisation might include everything from the feel of the bow handle and tab as the shot starts, through the muscle feel, alignment, feel of face contact, visual image of the aim, feel of the draw through the clicker, feel of the explosion and follow-through and simultaneous picture of the shot arcing into the gold. Very useful part of pre-performance preparation in "closed" sports like archery where action is initiated by the archer, not by a competitor or external event.
