Considers the potential value of two bodies of thought arising from work on animals in connection with rehabilitating abnormal behavior. One deals with the processes of catch-up and self-regulation, the other with optional periods of learning in development. (MP)

We introduce the thematic collection by noting some striking similarities in the cognitive abilities of human infants and nonhuman primates. What are the implications of these similarities for our comprehension of human infant cognition? After providing a brief historical and conceptual background on comparative behavioral research, we discuss how…

Examines how the contributions of animal research are presented in eight of the most widely used introductory psychology textbooks. The authors show that, with the exception of principles of conditioning and learning, the contributions of animal research are often not explicitly acknowledged or are obscured to look like they had been obtained with…

The ability to detect and learn about the predictive relations existing between events in the world is essential for adaptive behavior. It allows us to use past events to predict the future and to adjust our behavior accordingly. Pavlovian fear conditioning allows anticipation of sources of danger in the environment. It guides attention away from…

This paper introduces seven principles of learning, enduring over the last five centuries of psychological thought, to discuss the evolution of the "Biophyche" (the brain in action) in the development of humans and other large organisms. It describes the conditioning theories of Darwin, Pavlov, and Thorndike and critically reviews the…

In this article, research on nonhuman animals is reviewed to show that there is no discontinuity between humans and other animals. For both, high density is not necessarily harmful. Rather, the effect of high density depends on other factors in the situation. (Author)
