Presentation at the ABA International Conference 2024


Making a Difference as a Behavior Analyst


Baer, Wolf, and Risley’s (1968, 1987) seven dimensions of applied behavior analysis (ABA) have served the science and its practice well. ABA embodies five additional characteristics that should raise the spirits of those who study, teach, practice, and/or research this science and encourage decision makers and consumers in many domains to view ABA as a trustworthy technology for achieving socially significant behavior change.

I will identify those characteristics and suggest several actions behavior analysts, regardless of role or career stage, can take to narrow the gap between ABA’s tremendous potential to help make the world a more humane place and the science’s much-too-limited impact to date.
