This book, based on the Flowerree Mardi Gras Symposium at Tulane University, juxtaposes contemporary research and theory from several areas of animal learning -- learning theory, comparative cognition, animal models of human behavior, and functional neurology. Investigators pursuing these different routes often work in isolation of progress being made in, what should be, related fields. This book will acquaint students and researchers with a variety of topics, ordinarily treated separately, in a way that will stimulate integrative thinking. Cognitive interpretations of animal learning are included, as well as recent developments in conditioning theory, physiological bases of learning, animal models of human behavior problems, and psychopharmacology.
