Quiet eye (QE) is defined as the period of time in which the final visual fixation is performed to a target before the beginning of the motor response (Vickers, 1996). This time allows athletes a motor programming of a longer duration while it minimizes distractions by other environmental signals. QE duration is critical to cognitive processing, considering that visual information needs some time to be processed before performing the action. Therefore, longer QE improves motor performance.
Studies in elite and amateur athletes demonstrate differences between both. The QE in elite athletes is significantly longer with earlier fixations. Somehow they found the way to obtain sooner critical information.
Under conditions of competitive anxiety, athletes that have better performance keep their gaze control and attention. Both gaze control and attention can be improved by training QE.
