ABA Fundamentals

The operant conditioning of conversation.

★ The Verdict

Reinforce the exact speaker turn you want and the group will follow it.

✓ Read this if BCBAs running social-skills groups or staff-training sessions.
✗ Skip if Clinicians who only work one-to-one with non-vocal clients.

01Research in Context

01

What this study did

The researchers ran four small lab tests with neurotypical adults.

They used differential reinforcement to decide who talked next in a group chat.

When the target person spoke at the right time, the experimenter gave points that could be traded for money.

Other talk orders earned nothing.

02

What they found

The points quickly shaped who spoke and when.

Across all four tests, the group followed the target speaking order as soon as the rule changed.

Conversation flow became a simple operant response under tight experimental control.

03

How this fits with other research

Horner (1971) first showed that reinforcing “no response” beats plain extinction. G et al. moved the same logic from rat levers to human talk.

Bensemann et al. (2015) and Hangen et al. (2020) warn that differential reinforcement can accidentally boost untargeted behavior. G et al. did not track side talk, so their clean control may hide the same spillover.

Koegel et al. (2014) later extended the tactic to adults with ID, using DR to favor independent over prompted replies. The 1962 study gave them the basic playbook.

04

Why it matters

You can script who speaks when in social-skills groups, classroom circles, or staff meetings. Pick the speaker order you want, reinforce it, and watch the pattern lock in. Just track any extra chatter the schedule might accidentally feed.

03Original abstract

Human conversation is a natural place to begin the study of social responses. In a conversation, a number of individuals use one another's responses as cues for their own behavior. So long as a conversation is being held, the speakers must talk in some order. Four experiments were conducted to test whether differentially reinforcing a group of speakers can bring the order of speakers under experimental control. The results are all consistent with the hypothesis. The paper also devises and evaluates different procedures for studying conversational sequences and examines associated statistical problems.
