Impulse Control in the Batter's Box
In baseball, when the hitter steps into the batter’s box, with few exceptions, he activates his motor system to swing the bat on each pitch, a strong bias that creates a strong impulse to swing. As he processes the visual details of the pitch, this information is fed forward to the motor control system to begin activating the swing and bat path dynamics to deal with that pitch. For example, if the pitch has a high trajectory, the motor system begins activating delivery of a steeper bat path to get to the high pitch. This initial activation creates an impulse to react that must be controlled until a final decision is made about whether to swing at the pitch or withhold that swing. Thus, each pitch activates a specific swing impulse, the strength of which is shaped by a few factors, including the hitter’s approach, the pitch type, pitch velocity, and the proximity of the pitch to the strike zone or the hitter’s attack zones. Pitches way out of the strike zone activate weak and relatively easy to control swing impulses, whereas pitches around the hitter’s attack zone activate strong and relatively tough to control swing impulses. For hitters with poor impulse control, activation of specific swing impulses, even weaker ones, will be harder to control. The S2 Impulse Control task quantifies how well a player can control strong impulses to react.
