Avoidance of timeout from response-independent reinforcement.

D'Andrea (1971) · Journal of the experimental analysis of behavior 1971
★ The Verdict

Organisms will work hard to postpone even brief timeouts from free reinforcement, so treat timeout as a true punisher, not a gentle pause.

✓ Read this if BCBAs who use timeout or response-interruption in classrooms or clinics.
✗ Skip if Practitioners who rely only on differential reinforcement without timeout.

01Research in Context

01

What this study did

Hirota (1971) placed rats in a box where food dropped on its own every few seconds. If the rat did nothing, a timeout shut off the food for a short while.

The rat could press a lever to delay each timeout. The team asked: will the rat work just to keep the free food coming?

02

What they found

The rats pressed steadily. They treated the timeout like a tiny punishment and worked to avoid it.

When food dropped more often, the rats pressed even faster. Richer free food made the timeout feel worse.

03

How this fits with other research

Richardson et al. (2008) ran the same box and got the same lift in pressing with sweeter pellets, a clean direct replication.

McGee et al. (1983) later showed the opposite trend: longer delays before timeout cut pressing. This is not a clash—both agree that faster timeouts feel more aversive and drive more work.

Rose et al. (2000) proved the point is not the food. Pigeons pressed to postpone timeout even when pressing earned zero extra pellets—pure escape from the pause itself.

04

Why it matters

Timeout is not neutral. Clients will act to dodge it even when reinforcement keeps flowing. Use short, clear timeout signals and keep the ongoing schedule rich if you want the break to suppress problem behavior. Watch for avoidance responses—like leaving the area or stalling—that could accidentally be strengthened.

03Original abstract

Responses on a lever by rats postponed scheduled timeouts, or periods during which the delivery of response-independent food was withheld. The effects of a number of experimental variables were examined and the conclusions drawn are that the functional relations describing free-operant avoidance of timeout from response-independent reinforcement are similar to those for avoidance of electric shock and that both phenomena are sensitive to the same parametric manipulations. Results suggest that high frequency of food delivery in timein maintains a higher rate of timeout avoidance than low frequency. The evidence argues against an interpretation in terms of adventitious food-reinforcement of the timeout avoidance response. Finally, the effects of scheduling timeouts independently of responding and of omitting timeouts confirm the view that timeouts can be aversive and may act as punishment for responding.
