Baseball players, like most athletes, are not emotionless robots. The pressure of the moment can affect their performance. Think of the pitcher-batter duels, where one team is one swing away from victory or defeat. The well-trained brain of the pitcher knows what to throw and the experienced batter knows what to expect.
Yet, athletes can’t always mask the stress they’re feeling, giving away possible cues to their opponent. Staring back at the pitcher, a hitter might be able to subconsciously detect fear or uncertainty which may help him predict the type, speed and location of the next pitch. That interaction is what Dr. Arik Cheshin of the University of Haifa wanted to understand.
