In the late 1950s and early 1960s, sports were becoming more important to people. So, psychology of sports was more accepted because it helped athletes. Four things were important to expand the field of sports psychology. These were textbooks, graduate programs, associations, and journals. One of the main areas that was being studied during this time period was the affect stress had on athletes and their performance. In 1960, Warren R. Johnson continued the research he started in 1949. This research was about the effect stress had on an athlete. He continued this research by creating the first textbook on the topic. In 1961, Maxwell Howell started the first graduate school program in physical education. He did this at the University of Alberta in Canada. The creation of associations and journals was the next development of this time period. In 1967, the North American Society for the Psychology of Sport and Physical Activity or (NASPSPA)was created. It was created by a group of sport psychologists led by Warren Johnson. One of the first things that this organization did was to start publishing the "Sport Psychology Bulletin". The "Sport Psychology Bulletin" included research reports and the writings of the members of the NASPSPA. Then in 1970, the "International Journal of Sport Psychology" was started. During the 1970s and 1980s, there were many associations and journals that were started. These were the Association for the Advancement of Applied Sport Psychology, the American Psychological Association's Division 47 of Exercise and Sport Psychology, the Sport Psychology Academy of the American Alliance for Health, Physical Education, Recreation, and Dance, the "Journal of Sports Psychology", the "Journal of Sport Science", the "Sport Psychologist", and the "Journal of Applied Sport Psychology". The next major developments involved the United States Olympic Committee. In 1978, they started a Sports Medicine Council that included sports psychologists. In 1985, they created the first registry or list of sports psychologists.
