Sport psychology
The first sports psychology laboratory was opened in 1920 in Berlin, Germany by Carl Diem. That same year, a psychological lab was opened by Robert Werner Schulte at the Deutsche Hochschue fur Leibesubungen near Berlin. This was a college for physical education. The lab was used to study the natural ability that people had for doing good in sports.  Schulte also included sports psychology in his talks to students who took physical education. Then in 1921, he published his first book. This book was named Body and Mind in Sport. He then continued to go on to write many books about the topic of sport psychology. One of these books was called Aptitude and Performance Testing in Sport. The next development, in 1926, was the first psychoanalysis of what motivated people to want to play sports. This was done by Helene Deutsch. She found that playing in sports could help people with depression, anxiety and overcoming fears.
