Joseph J. Pear (1938-2022): Inventive, Innovative, Inquisitive

As a scientist, teacher, and author, Joseph J. Pear (1938–2022) made inventive and innovative contributions to the experimental analysis of behavior and applied behavior analysis. He collaborated on the invention of a computer-controlled video system that provided real-time tracking of an animal as it moved around its environment—the first system of its kind—and used this system to study the behavior of pigeons during schedules of reinforcement and autoshaping, Siamese fighting fish during Sidman avoidance tasks, and even lake sturgeon using darkness as a positive reinforcer. A pioneer in early online teaching, he developed a computer-aided version of Keller’s personalized system of instruction, a system known as CAPSI. Pear coauthored with Garry Martin a best-selling behavior modification textbook, and wrote his own books on topics such as the science of learning and psychological systems. Pear’s work exemplified the growing integration between basic and applied behavior analysis.
