Emotional control balances relaxation with arousal to permit better concentration. Emotional control uses 'controlled breathing' to relax muscles, and 'positive self-talk' to build confidence and correct errors. The competition dancer must work with their coach to determine which methods work best. To be effective, the coach must teach the dancer to relax on cue. Once emotional control is achieved, attentional control helps the dancer focus on the task at hand.
Attentional control involves concentration, visualization, and refocussing.
Concentration is the state of being relaxed and alert to the changing environment. Dancers would liken this to a crowded dance floor. If someone gets in the way, you must react while staying focussed on the performance. Visualization involves rehearsing a positive, mental image of the performance. It can also be used to anticipate problems that may impede performance.
