ABA Fundamentals

Comparing main and collateral effects of extinction and differential reinforcement of alternative behavior.

Petscher et al. (2008) · Behavior modification 2008
★ The Verdict

DRA beats extinction for speed, but extinction can lift schoolwork while risking aggression in the same kid.

✓ Read this if BCBAs running classroom programs for disruptive or off-task students.
✗ Skip if Clinicians who only treat in clinics where academic engagement is not a goal.

01Research in Context

01

What this study did

Petscher et al. (2008) tested two ways to stop loud talk-outs and work refusal in a classroom.

They used an alternating-treatments design. Some days they ignored the problem (extinction). Other days they paid kids with tokens for doing the right thing instead (DRA).

Each kid got both treatments, so the team could watch side effects as they happened.

02

What they found

DRA cut problem behavior faster than extinction alone.

Yet extinction gave one child better on-task work and also sparked aggression in that same child.

No one showed the classic extinction burst—just the quiet trade-off above.

03

How this fits with other research

Bhaumik et al. (2009) looked at 116 DRA papers and call the package well-established. Their big picture matches the fast drop Seligson saw, but they do not flag the academic boost that only extinction gave.

Brown et al. (2020) ran DRA with and without extinction and later tested resurgence. Both sets of kids relapsed the same amount, even though the DRA-only group looked worse during treatment. This extends Seligson’s trade-off: quick DRA gains can hide equal long-term risk.

Briggs et al. (2019) also skipped extinction and still beat problem behavior by making the payoff for compliance bigger and better. Their success supports Seligson’s DRA speed, showing you can skip extinction if the alternative reward is strong enough.

Cohen et al. (1993) found DRO without extinction failed for two of three kids. That seems to clash with Briggs and Seligson, but the difference is procedure: DRO pays for any break in problem behavior, while DRA pays for a true replacement skill. The lesson: pick the right alternative response, not just any response.

04

Why it matters

You now know DRA will probably give you the quickest drop in talk-outs or refusal, so use it when the team needs fast relief. If the child also needs higher academic engagement, try short extinction bursts, but watch for sudden aggression and be ready to switch. Keep data on both academics and aggression so you catch the trade-off before it surprises you.

03Original abstract

This study evaluated the effects and collateral effects of extinction (EXT) and differential reinforcement of alternative behavior (DRA) interventions with inappropriate vocalizations and work refusal. Both interventions have been used frequently to reduce problem behaviors. The benefits of these interventions have been established yet may be outweighed by the reported negative side effects that result. However, these collateral effects have rarely been measured or reported. DRA produced the most rapid reductions in behavior for 4 of the 5 participants. Other behaviors were measured for changes and showed that the desirable collateral effect of academic engagement tended to be higher during EXT than DRA. No evidence of EXT bursts was present with any participant, although EXT-induced aggression occurred with 1 participant.
