researchers. Beginning in 1895, James Mark Baldwin (Princeton, Hopkins) and Edward Bradford Titchener (Cornell) entered into an increasingly acrimonious dispute over the correct interpretation of some anomalous reaction time findings that had come from the Wundt laboratory (originally reported by Ludwig Lange and James McKeen Cattell). In 1896, James Rowland Angell and Addison W. Moore (Chicago) published a series of experiments in Psychological Review appearing to show that Baldwin was the more correct of the two. However, they interpreted their findings in light of John Dewey's new approach to psychology, which rejected the traditional stimulus-response understanding of the reflex arc in favor of a "circular" account in which what serves as "stimulus" and what as "response" depends on how one views the situation. The full position was laid out in Dewey's landmark article "The Reflex Arc Concept in Psychology" which also appeared in Psychological Review in 1896. Titchener responded in Philosophical Review (1898, 1899) by distinguishing his austere "structural" approach to psychology from what he termed the Chicago group's more applied "functional" approach, and thus began the first major theoretical rift in American psychology between Structuralism and Functionalism. The group at Columbia, led by James McKeen Cattell, Edward L. Thorndike, and Robert S. Woodworth, was often regarded as a second (after Chicago) "school" of American Functionalism (see, e.g., Heidbredder, 1933), although they never used that term themselves, because their research focused on the applied areas of mental testing, learning, and education. Dewey was elected president of the APA in 1899, while Titchener dropped his membership in the association. (In 1904, Titchener formed his own group, eventually known as the Society of Experimental Psychologists.) Jastrow promoted the functionalist approach in his APA presidential address of 1900, and Angell adopted Titchener's label explicitly in his influential textbook of 1904 and his APA presidential address of 1906. In reality, Structuralism was, more or less, confined to Titchener and his students. (It was Titchener's former student E. G. Boring, writing A History of Experimental Psychology [1929/1950, the most influential textbook of the 20th century about the discipline], who launched the common idea that the structuralism/functionalism debate was the primary fault line in American psychology at the turn of the 20th century.) Functionalism, broadly speaking, with its more practical emphasis on action and application, better suited the American cultural "style" and, perhaps more important, was more appealing to pragmatic university trustees and private funding agencies.
