Behavioral Measurement as Centerpiece

Hank Pennypacker's interest in behavioral measurement began early in his career and gradually became the centerpiece of his diverse accomplishments. A review of his focus in the 1960s is followed by a brief summary of the evolution of behavioral measurement practices in applied behavior analysis as it emerged from the field's laboratory history. This examination serves as pretext for a discussion of the contributions of Strategies and Tactics of Human Behavioral Research (Johnston & Pennypacker, 1980), Strategies and Tactics of Behavioral Research (Johnston & Pennypacker, 1993a, 2009), and Strategies and Tactics of Behavioral Research and Practice (Johnston et al., 2020) to emerging matters of behavioral measurement. That discussion focuses on how issues raised by the challenges of applied research and practice have evolved.
