ABSTRACT
This chapter considers the theories, concepts and ideas of three people who had an important influence on humanistic psychology: Abraham Maslow, Carl Rogers and George Kelly. Whilst humanistic psychology only became an important influence in psychology in the 1950s its roots date back nearly 200 years. Abraham Maslow is often regarded as the person who both popularised and influenced the development of the third force in psychology. Rogers was also keenly aware of social issues in the United States of America, and attempted to show how humanistic psychology could help improve education and contribute to achieving world peace. Personal construct theory has enjoyed a greater take-up in Great Britain than in the USA, perhaps because of the establishment of the Centre for Personal Construct Psychology in London by Bannister and Fransella. The British psychologists Donald Bannister and Fay Fransella opened the Centre for Personal Construct Psychology in London.
