Performance psychology is a field that examines the factors that contribute to optimal performance in various domains, such as sports, business, education, and the arts. The foundations of performance psychology can be traced back to the early 20th century and the development of sport psychology, which focused on the psychological factors that influence athletic performance. Over time, the field expanded to include other domains and now encompasses a range of topics, such as motivation, goal setting, attentional focus, stress management, and mental imagery. Performance psychologists work with individuals and teams to help them enhance their performance, manage stress and anxiety, and achieve their goals. They use a range of techniques and interventions, such as goal-setting, mental rehearsal, self-talk, and cognitive restructuring, to help individuals and teams improve their performance and overcome obstacles. Performance psychology is a rapidly growing field, with applications in areas such as sports, business, healthcare, and the military.
