<P> Hall was an early psychologist in the field of anomalistic psychology . Hall and his assistant Amy Tanner from Clark University were notable debunkers of spiritualism and carried out psychological and physiological tests on mediums . Tanner published Studies in Spiritism (1910) with an introduction by Hall . The book documented the tests carried out by Hall and Tanner in the séance sittings held with the medium Leonora Piper . Hall and Tanner had proven by tests that the personalities of Piper were fictitious creations and not discarnate spirits . </P> <P> Hall was deeply wedded to the German concept of Volk, an anti-individualist and authoritarian romanticism in which the individual is dissolved into a transcendental collective . Hall believed that humans are by nature non-reasoning and instinct driven, requiring a charismatic leader to manipulate their herd instincts for the well - being of society . He predicted that the American emphasis on individual human right and dignity would lead to a fall that he analogized to the sinking of Atlantis . </P> <P> Hall was one of the founders of the child - study movement in the 1880s . A national network of study groups called Hall Clubs existed to spread his teaching . He is popularly known today for supervising the 1896 study Of Peculiar and Exceptional Children, which described a series of only child eccentrics as permanent misfits . For decades, academics and advice columnists alike disseminated his conclusion that an only child could not be expected to go through life with the same capacity for adjustment that siblings possessed . "Being an only child is a disease in itself," he claimed . </P> <P> Hall argued that child development recapitulates his highly racialized conception of the history of human evolutionary development . He characterized pre-adolescent children as savages and therefore rationalized that reasoning was a waste of time with children . He believed that children must simply be led to fear God, love country, and develop a strong body . As the child burns out the vestiges of evil in his nature, he needs a good dose of authoritarian discipline, including corporal punishment . He believed that adolescents are characterized by more altruistic natures than pre-adolescents and that high schools should indoctrinate students into selfless ideals of service, patriotism, body culture, military discipline, love of authority, awe of nature, and devotion to the state and the well being of others . Hall consistently argued against intellectual attainment at all levels of public education . Open discussion and critical opinions were not to be tolerated . Students needed indoctrination to save them from the individualism that was so damaging to the progress of American culture . </P>
