Positive psychology
Positive psychology grew as an important field of study within psychology in 1998 when Martin Seligman chose it as the theme for his term as president of the American Psychological Association. In the first sentence of his book "Authentic Happiness", Seligman claimed: "for the last half century psychology has been consumed with a single topic only – mental illness," expanding on Maslow's comments. He urged psychologists to continue the earlier missions of psychology of nurturing talent and improving normal life.
