Collected Works of C.G. Jung, Volume 2: Experimental Researches

After joining the staff of the Burghölzli Mental Hospital in 1900, Jung developed and applied the word-association tests for studying normal and abnormal psychology.  Between 1904 and 1907 he published nine studies on the association experiment, of which six were brought together, with articles by other researchers, in a collection later published in English as Studies in Word-Association (1918).  The present volume consists of the original nine studies together with two lectures on the association method that Jung gave in 1909 when, with Freud, he was invited to Clark University, Worcester, Massachusetts, and three articles on psycho-physical researches.

Jung’s earlier work showed the definite influence of Bleuler and also of Freud, to whom he sent a copy of the association studies in 1906.  A correspondence began, and the two men met in Vienna in 1907, thereafter working together for several years.  The association studies have remained a significant phase in the development of Jung’s conceptions and an important contribution to diagnostic psychology and psychiatry.
