Life-Span Developmental Psychology: Dialectical Perspectives on Experimental Research is a compilation of papers that deals with the dialectical perspective focusing on the developmental process of the individual’s interaction with the environment. Part 1 discusses the theoretical issues of psychological theorists such as Piaget and Kaplan. The text includes topics such as the dialectics of time and post-Newtonian metatheory for psychologists. One paper discusses the dialectic method and theory in the work of psychology as social proof structures, particularly when systems of action cause conflict with systems of thought. The text analyzes research versus theory through the Wundt-Titchener Laboratory example. Another paper addresses the status of dialectics in developmental psychology using the approach of theoretical orientation versus the scientific method. Part 2 presents research applications covering topics such as the phenomenological and a behavioral approach to remembering, as well as ""remembering"" in empiricism. Another paper addresses the dialectical perspectives of discriminative learning and transfer that includes both theory and research done on discriminative performance. This book will prove valuable for psychologists, behavioral therapists and researchers, and students in behavioral psychology.
