Syllabus: Why Does Learned Behavior Persist—and When Does It Change?
Apply the opening review's framework to ABA, AAB, and ABC designs. Ask which comparisons constrain the explanation that the original reward-associated context alone revives responding.
A question to consider. Which finding would be most informative if your explanation predicted recovery only in the original training context, and why?
Why this reading
A response can return outside the setting where it stopped. These experiments make the context comparison precise and ask whether returning to the original setting is necessary for renewed responding.
Before you read
Rats press a lever for food before the response is extinguished. The letters in ABA, AAB, and ABC denote the contexts of acquisition, extinction, and testing, in that order. A context is a combination of environmental features, including the chamber's appearance and odor. Free operant behavior can occur repeatedly without a separate experimenter-defined trial for each response.
Read for
- Diagram the three phases and both test settings. Explain why AAB and ABC comparisons add information beyond ABA renewal.
- Inspect counterbalancing and the tests without food. Ask what renewed responding establishes before any opportunity for reinforced relearning.
- Follow the extra extinction sessions and the exposure to the acquisition context without the lever. Separate the alternatives these controls constrain from the mechanisms they leave open.
Consider afterwards
- A response stops in one room and returns in a second. Design a comparison that could distinguish a special effect of the original training room from an effect of leaving the extinction room.
Editorial context
The four experiments concern food-reinforced lever pressing in rats. The context manipulations support context-dependent extinction but do not uniquely identify an inhibitory association, an occasion-setting process, or a neural mechanism. Tripling extinction did not reduce AAB renewal in the tested procedure; this does not show that extra extinction never helps. Wang and colleagues' human fear-conditioning meta-analysis (2024) offers a separate evidence base for assessing cross-species and cross-task generalization.
