Positive psychology began as a new domain of psychology in 1998 when Martin Seligman chose it as the theme for his term as president of the American Psychological Association. It is a reaction against past practices, which have tended to focus on mental illness and emphasized maladaptive behavior and negative thinking. It builds on the humanistic movement by Abraham Maslow, Rollo May, James Bugental and Carl Rogers, which encouraged an emphasis on happiness, well-being, and positivity, thus creating the foundation for what is now known as positive psychology
