In Memory of Beth Sulzer-Azaroff from Trustee Kent Johnson

The Cambridge Center for Behavioral Studies is sad to report that we lost this distinguished member of our community....

Interview with Dwight Harshbarger

“This stuff is powerful, I’m gonna keep doing it.”

Interview with Janet S. Twyman, PhD, BCBA, LBA

…my approach is the same: make sure the behavior is doable; ensure there’s motivation and environmental support; reduce or eliminate coercion; always look to the contingencies.

Interview with Ramona Houmanfar, PhD

“I’m proud of my students and their work, and how we developed a line of research related to communication/verbal behavior and RFT/rule governance in organizations. Developing your niche is hard to do and takes courage.”

Interview with Ronnie Detrich

“Behavior analysts should work on speaking to a broader audience in ways that the audience is receptive to and finding ways to disseminate and tell our story more effectively.”

Interview with Andy Lattal, PhD

“I am most proud of the 43 doctoral students I have trained, and the numerous sabbatical visitors who have spent time working with me. These people are the future of our field…”

Interview with Philip Hineline, PhD

“While Skinner was a very nice guy he was often demonized. Many people only accept behavior analysis after they see the practical applications.”

Interview with Francis Mechner, PhD

“If you want to make advances in your field, don’t stay in the safe and fashionable middle, go for the edges.”

Interview with Charles Catania, PhD

“We need to find more and better ways to educate the general public about our science.”

Interview with Rob Holdsambeck, PhD, BCBA‑D

“Getting a child with Autism to communicate with signs, symbols or words when they previously used ‘meltdowns.’…I am happy that the company I created gives opportunities to these kids (and also lots of jobs to talented ABA professionals).”

Interview with Eitan Eldar, PhD, BCBA‑D

“We began an instructional program in 1990 with three students. Now there are over a hundred students and more than 10 staff in that program, plus a few other programs in Israel.”

Interview with Lori Ludwig, PhD

“I’ve worked in a variety of industries including automotive, human services, non-profit, print, retail, and oil and gas across a range of companies, from global Fortune 500s, creative start-ups, to local small businesses.”

Interview with Kent Johnson, PhD

“I tutored 40 kids when I was 9-12 years old. In college, I became passionate about…catering to children who could do better if we taught them better. Behavior analysis was the vehicle for me to make gains in education.”

Interview with Joe Dagen, PhD

“I use the science of behavior every day! The energy industry is very exciting, and now more than ever.”
