An up-to-date approach to behavior analysis within the framework of evolutionary theory Introduction to Behavior is a contemporary textbook for students in behavior analysis and other behaviorally-oriented disciplines. Dispensing with outdated models of behavior and reinforcement, this book adopts a new conceptual framework for the understanding of behavior, human and nonhuman. It will help students at all levels, particularly students being trained in applied behavior analysis, offering an easily approachable and plausible framework that can inform both research and practice. Excellent for undergraduate and graduate students alike, as well as others interested in the field of behavior science, this book covers standard topics in behavior analysis from an up-to-date perspective. Readers will be introduced to a far more effective way of viewing behavior than the traditional reinforcement-based approach. Examine traditional concepts of behavior analysis from an evolutionary perspectiveGain a concrete conceptual framework that can be used to guide research and practice in applied behavioral scienceUnderstand human and nonhuman behaviors, both in laboratory settings and in daily life, from an individual and a social perspectiveBuild your knowledge of why people make the choices they make given particular environmental inputs Introduction to Behavior fills an important gap in available texts on behavior analysis, placing helpful behavioral concepts within a sound, evidence-based evolutionary framework.
