Early interactions between animal psychologists and animal activists and the founding of the APA Committee on Precautions in Animal Experimentation.

The current conflict between animal psychologists and animal rights activists often is presented as a recent and unique phenomenon. Although its scope may be unprecedented, the fundamental issues are longstanding. Early criticisms of animal psychologists are viewed in the context of the broader Victorian antivivisectionist movement and are seen as similar to those of the present time. Various attitudes toward animals and research were expressed by individuals such as Charles Darwin, George John Romanes, William James, and John Dewey. Media attacks on animal research were directed at psychologists such as G. Stanley Hall, John B. Watson, Ivan P. Pavlov, and Edward L. Thorndike. The American Psychological Association Committee on Precautions in Animal Experimentation was founded in 1925 at the instigation of Walter B. Cannon, with Robert M. Yerkes as the first chair.
