International Perspectives on Comparative Psychology
Psychology in general-and comparative psy chology in particular-has developed unequally in the world (e.g., Sexton and Hogan, 1992). The scientific study of psychological processes in animals and its comparison with psychologi cal functioning in humans took root originally in countries such as England, the United States, Germany, Russia, and France and only later in other nations. At the beginning it was an AngloSaxon discipline, derived from Darwin, with important contributions from Watson and the behaviorists. Today there are important re search groups in many countries of the world.
