- Description
- This typescript is Samuel Kavruck’s copy of a quick test for introversion and extroversion developed by Alfred R. Root. The test consists of ten questions about personal preferences and five possible answers. Subjects were asked to check the answer that best described their preference. According to Hopkins, the Psychological Corporation published a version of the test in 1932. Eight of the ten questions were taken from a longer test by psychiatrist Clarence A. Neymann and Kenneth D. Kohlstedt. The Neymann-Kohlstedt test was published by Stoelting in 1928.
- Alfred R. Root (1900-1987), born in Wisconsin, did his undergraduate work at Lawrence College, received an M.A. from the University of Chicago in 1925, and obtained a PhD. from the University of Iowa in 1928. From 1923 to 1925 he was the head of the Department of Speech at Northern State Teacher’s College in South Dakota and from 1928 to 1936 a professor at Hamline University in St. Paul, Minnesota. The following year he became director of research at the Knox-Reeves Advertising Agency in Minneapolis, a position he retained at least into the 1960s.
- Some of Root’s work on introversion and extroversion was carried out jointly with his wife, Elizabeth Bell Root (1906-1986).
