Abstract
As I reread my review nearly 50 years later, I think of the circumstances. I had heard a paper by Fred at the Ithaca meeting of the APA in 1932, and recall the praise by Edna Heidbreder, who was sitting next to me, whose remark was that “He has a clean mind.” The year before his book appeared, I had already cited eight of his published papers in a review of the conditioned response in relation to conventional learning experiments that appeared in the Psychological Bulletin (1937, 34, 61–102). It may be because of that the editor sent me Fred's book to review.
When I received the copy of his new book to review, I read it carefully, and soon reported on it orally before Lewis Terman's weekly seminar to get comments and questions before revising my review. I was pleased by Terman's excitement over the originality of Fred's approach.
