Prepared as a tribute to Donald A. Riley, the essays that appear here are representative of a research area that has loosely been classified as animal cognition -- a categorization that reflects a functionalist philosophy that was prevalent in Riley's laboratory and that many of his students absorbed. According to this philosophy, it is acceptable to hypothesize that an animal might engage in complex processing of information, as long as one can operationalize evidence for such a process and the hypothesis can be presented in the context of testable predictions that can differentiate it from...

In 1978, Hulse, Fowler, and Honig published Cognitive Processes in Animal Behavior, an edited volume that was a landmark in the scientific study of animal intelligence. It liberated interest in complex learning and cognition from the grasp of the rigid theoretical structures of behaviorism that had prevailed during the previous four decades, and as a result, the field of comparative cognition was born. At long last, the study of the cognitive capacities of animals other than humans emerged as a worthwhile scientific enterprise. No less rigorous than purely behavioristic...

Decision making cuts across most areas of intellectual enquiry and academic endeavor. The classical view of individual human thinkers choosing among options remains important and instructive, but the contributors to this volume broaden this perspective to characterize the decision making behavior of groups, non-human organisms and even non-living objects and mathematical constructs. A diverse array of methods is brought to bear-mathematical, computational, subjective, neurobiological, evolutionary, and cultural. We can often identify best or optimal decisions and decision making processes,...
