This is the first comprehensive volume to bridge the gap between the science of behavior and applied behavior analysis (ABA). The book demonstrates how laboratory research informs real-world interventions to facilitate behavior change, and vice versa. Most of the chapters are written by researcher–clinician collaborators, who highlight commonalities and differences in the ways they conceptualize behavior and collect, analyze, and use data. Chapters present translational perspectives on conditioning, reinforcement, extinction, choice, verbal behavior, and more. Ethical considerations in translational research are explored. Training in foundational knowledge is a key requirement for behavior analyst certification, making this a needed resource for current and future ABA practitioners.
