The vision factor kicks in the second the pitcher’s wind-up commences. The visual system of the brain takes cues from where the image of the pitchers wind-up lands on the back surface of the eye (the retina). When the image of the wind-up hits the retinas of the eyes, the brain starts calculating based on the batters observation of (1) where the pitcher’s eyes are focused, (2) the speed with which the wind-up occurs and (3) the angle of his shoulders in relation to the rest of his body.
We have all heard of binocular vision and this is where both eyes seeing together is gives us our best ability to judge one object’s distance from another. The better our binocular vision the better we can hit the baseball whether it is little league to the majors.
At the point of release of the ball from the pitchers hand, the brain takes the image of the ball and calculates where the image of the pitch might fall on the retina. At this point, the eye locks onto the ball with the center of the retina and now is the time the pitcher’s visual brain is determining whether to strike at the ball assuming where it might come over the home plate. The brain uses these cues to determine what plane to place the swinging bat. The brain determines timing when hitting a baseball.
The back of the brain where visual images are interpreted by all of us when we think we see something is the time our visual motor control system kicks in telling the batter if he should swing.
Signals are sent to the fingers, hands wrists, forearms, elbows and shoulders as well as to the feet, legs, hips and torso for movement that will align the bat along the trajectory of the ball. The goal is to have the bat end up in the same plane as the ball as the ball crosses the plate. The key to success in hitting the ball is as little head motion as possible.When the head moves, the image of the trajectory of the projectile (ball) shifts, necessitating a micro-second recalculation. A micro-second too late, and STRIKE!
