The Animal Mind at 100

To celebrate the 100th anniversary of the publication of Margaret Floy Washburn’s (1908) The Animal Mind: A Text-book of Comparative Psychology, the book is reviewed and compared to contemporary comparative texts. Although considerable advances have been made with respect to topics, methods, and findings, of course, the original text remains remarkably relevant, both as an introduction to animal psychology and as a marker of changes in the discipline that spanned the book’s four editions.
