G. Stanley HallDied 24 Apr 1924 at age 80 (born 1 Feb 1844). Granville Stanley Hall was an American psychologist who distinguished experimental psychology in the U.S. from the philosophical psychology that dominated in America at the time. He developed child psychology and educational psychology. He coined the phrase “Storm and Stress” relative to adolescence, with the three key aspects of conflict with parents, mood disruptions, and risky behaviour. Influenced by Charles Darwin's Theory of Evolution, Hall undertook a scientific examination of child development in the aspect of the inheritance of behaviour. He also pioneered the use of questionnaires. In 1887, Hall founded the American Journal of Psychology to publish psychological research from authors regardless of their disciplinary background.« |
