Sportswriter Hugh S. Fullerton is involved in the next development in the history of sports psychology. Fullerton brought New York Yankees player Babe Ruth to a psychology laboratory at Columbia University. Fullerton brought Ruth there to participate in a study run by Albert Johanson and Joseph Holmes. He wanted Ruth to participate in the study because he wanted to find a reason for why Ruth hit so many home runs. He also wanted to prove to other baseball scouts whether or not other players like Ruth existed. The study that Ruth participated in was used to study sensory-motor performance. Sensory-motor performance is how things that we perceive with our senses influence our movements. The study involved measuring the power of Ruth’s swing, his reaction time, his attention, his memory, and his motor skills. The results of this study offered a reason for why Ruth hit so many home runs. His skill for hitting home runs could be because on the tests his motor skills and reflexes scored above average. The next development that came regarded football. At Stanford University, B.C. Graves, a psychology graduate student, Walter Miles, a professor, and Glenn “Pop” Warner, a college football coach started an experiment. Their experiment studied reaction time. They ran their ran experiment so they could find the fastest way to get the offense to move together when the center hiked the ball. This led to the use of psychology as a way to gain an advantage over your opponent in a competition.
