Experimental self-punishment and superstitious escape behavior.

MIGLER (1963) · Journal of the experimental analysis of behavior 1963
★ The Verdict

Brief shocks failed to stop escape bar-holds, proving that punishment layered on negative reinforcement can leave the target behavior untouched.

✓ Read this if BCBAs who use or plan to use punishment while the behavior still produces escape from aversive events.
✗ Skip if Clinicians working only with positive-reinforcement programs and no punishment component.

01Research in Context

01

What this study did

The researchers punished bar-holding with brief shocks during escape training. They wanted to see if the shocks would stop the animals from holding the bar.

The animals could end shocks only by holding the bar. Then the same bar hold also produced a quick extra shock. The study kept this two-part setup running for many sessions.

02

What they found

The brief shocks did not reduce bar-holding. The animals kept holding the bar even though that choice brought thousands of extra shocks.

When the shocks became inescapable, the animals still pressed and held the bar. The escape response had turned into a superstitious habit that would not turn off.

03

How this fits with other research

Ulrich (1967) used the same shock-escape lab setup but changed the social layout. When a clear partition blocked fighting, escape stayed smooth. When the partition came out, fighting burst out and escape fell apart. Both papers show that extra events layered on escape do not always weaken the response.

Thompson et al. (1971) also used electric shock, but with turtles. Shock there produced threat and biting, a built-in defense pattern. MIGLELong (1963) shows that shock can also lock in an operant escape habit. Together the three studies map different ways aversive stimuli steer behavior.

English et al. (1995) looked at cost using unit price. As the price of opioid rose, consumption dropped. In MIGLELong (1963) the price of escape also rose because each response added a shock, yet consumption of the response stayed high. The findings do not clash; they simply show that escape maintained by negative reinforcement can resist added cost more than drug reinforcers do.

Why it matters

If you add a mild punisher to stop an escape behavior, the response may keep going. Check whether the behavior is still under negative reinforcement. If it is, strengthen the replacement or remove the reinforcer instead of stacking on more punishment.

Before you add a punisher to an escape-driven behavior, test a reinforcement-only alternative and track if the escape contingency is still active.

03Original abstract

Rats were trained to escape from shock by pressing a bar. Bar holding was subsequently punished with very brief shocks. This treatment failed to depress bar-holding behavior. In some cases, although the escape shocks were delivered very infrequently, bar holding was maintained and resulted in the delivery of several thousand punishments per session. These and other effects of the punishment treatment were investigated. Finally, some of the possibilities of superstitious escape responding were explored by presenting inescapable shocks to rats that had been trained to escape shock by lever pressing. Although responding during these shocks had no programmed consequences, responding was sustained.
