The Legacy of Adolf Meyer's Comparative Approach: Worcester Rats and the Strange Birth of the Animal Model

摘要

The breeding of albino rats had an enormous impact on experimental psychology in the twentieth century. Rats were, and for many questions still remain, the "standard animal" for laboratory research in neurology, psychology, and physiology. Albert Meyer was one of the figures most responsible for developing the albino rat as an experimental model Despite Meyer's pioneering work with albino rats, his rat research has received only sparse attention. Little is known about the way in which the animal served Meyer's more famous psychiatric program. In this article, the author discusses the role that albino rats played in Meyer's animal research. He then turn to the contrast between the way in which Meyer viewed the animal's role in research and the way rats were later used as a laboratory "standard" to assure scientific generality. This comparison highlights the changes that occurred in comparative psychology in the twentieth century, and it further clarifies some of the concerns associated with the use of animal models today.
