The model system of eyeblink classical conditioning in humans has enormous potential for the understanding and application of fundamental principles of learning. This collection makes classical conditioning accessible to teachers and researchers in a number of ways. The first aim is to present the latest developments in theory building. Second, as background for directions in 2000, the text presents an overview of a large body of previously published research on eyeblink classical conditioning. Last, the authors describe eyeblink classical conditioning techniques. Each chapter includes a highlighted methods section so that interested readers can replicate techniques for teaching and research.
