In 1903, G.T.W Patrick studied the psychology of American football and why people loved the game so much. Next in 1912, Howard wanted to discover why people became so emotional while watching sports. Then in 1915, Karl S. Lashley and John B. Watson started a study that focused on the learning curve of people in sports. A learning curve is how people learn the skills they need to in order to succeed in sports. The sport that they focused their study on was archery. The results of their study lead them to argue that when people were participating in harder tasks, like archery, they were more likely to work harder to complete the task.
