Comparative psychology 25 years after.

Examined articles published in the Journal of Comparative and Physiological Psychology (JCPP) and Animal Behavior (AB) in the 25 yrs since F. A. Beach first surveyed the literature in 1950. In the JCPP, the number of species studied remained relatively low in view of the greatly increased number of articles published, while the reverse was true of AB, whose articles were also more diversified in terms of number of species.
