Creative visualization is the cognitive process of generating mental imagery, with eyes open or closed, simulating or recreating visual perception in order to maintain, inspect, and transform those images and consequently modifying their associated emotions and feelings with intent to experience a subsequent beneficial effect, alleviating anxiety, improving self-esteem and self-confidence, and enhancing the capacity to cope when interacting with others.
For actors, mental rehearsal can make a big impact on performance. Research shows that mentally rehearsing scenes, monologues or auditions in your head is almost as effective as actual rehearsal. The explanation is that the same neural pathways are activated by mental rehearsal as actual rehearsal.
So how should you mentally rehearse? First, relax, find somewhere comfortable and quiet and breathe deeply. In through the nose, then hold and out through the mouth. Second, imagine in vivid details of sound, movement, feelings and visualisation, whatever you want to practise. Third, imagine it from beginning to end, including a successful conclusion. Fourth, repeat regularly. Mental rehearsal is a technique that athletes, musicians, doctors, soldiers, and even astronauts use to prepare for the worst and perform at their best.
