Escape, avoidance, punishment: where do we stand?
Hold on to two-factor avoidance theory, but update your toolkit with effort and antecedent reinforcement to cut problem behavior faster and safer.
01Research in Context
What this study did
Wasserman (1977) wrote a narrative review. The paper looked at three big ideas: escape, avoidance, and punishment.
It pulled together lab data from the 1960s and early 1970s. The goal was to see which theories still held up.
What they found
The review said escape is best explained by preparatory-response theory. Avoidance still fits the safety-signal two-factor model.
The paper also defended the idea that punishment works through avoidance, not just suppression.
How this fits with other research
Dunham (1972) had shown that punishing one response can increase an unpunished one through time re-allocation. That finding seems to clash with the avoidance view, but the 1977 paper argues the data still fit if you look at overall response classes.
Grace (1995) later offered response effort as a low-stress alternative to punishment. This updates the 1977 frame: you can cut behavior without any aversive at all by simply making the response harder.
Slocum et al. (2025) extends the escape idea to autistic children. Their RCT shows differential positive reinforcement beats escape extinction in the first ten sessions. The 1977 theory laid the groundwork; the 2025 study shows how to use it in clinic rooms today.
Ayvaci et al. (2024) adds a practical twist: when you must use punishment, pair it with antecedent reinforcement. The 1977 paper defends punishment’s mechanism; the 2024 review tells you how to deploy it with less collateral damage.
Why it matters
You still need the two-factor avoidance lens when you write punishment plans. Think: what safety signal am I giving? Also, try effort first—no approval forms needed. If you do use punishment, front-load reinforcement and watch for escape jumps.

03Original abstract
This paper reviews progress since the author's previous writings in three areas. In escape training, the preparatory-response explanation of bar holding still appears to be valid. In avoidance, the newer safety-signal version of two-factor theory has much to recommend it and readily incorporates Anger's conditioned aversive temporal stimuli formulation. Shock-density reduction is rejected as a substitute for two-factor theory. Finally, criticisms of the avoidance interpretation of punishment are answered and recent empirical data are cited in its support.
