The room sequence explains the comparison
Simplified map of the 2006 experiment, not instructions for a home exercise or a graph of personal relapse risk. A and B label laboratory rooms; all participants were tested in both.
| Stage | Room and cue relationship | What the stage tells us |
|---|---|---|
| Learning · A | Different tray colours signalled smoking availability or unavailability. | A difference in urge could first be learned. |
| Extinction · B | Neither colour was followed by smoking. | The previously learned difference in urge decreased. |
| Test · A and B | The same cues were tested in both rooms without smoking. | Comparing the rooms tested whether the reduced response depended on context. |
The quiet new office and the difficult old doorway
Consider a fictional example: someone has stopped smoking and usually feels little urge during breaks at a new office. A visit to the old office brings a strong urge near the side door once used for cigarette breaks. The contrast is real within the story, but the conclusion ‘I was only making progress because I moved’ goes further than the observation.
A setting is more than a location on a map. The doorway, familiar colleagues and anticipated break may form a different context from the new office. They can help explain why experiences differ without turning an urge into a smoking event. Stress, timing and other reminders may also have changed; one visit cannot isolate the cause.
What researchers actually changed
Thewissen and colleagues’ 2006 experiment enrolled 33 current smokers, mainly young adults, who were not intending to quit. In one room, coloured trays signalled whether smoking would be available. In another room, neither colour was followed by smoking. Researchers then tested both rooms, with test order counterbalanced. These were two laboratory rooms with relatively little smoking relevance—not the participants’ familiar smoking places.
The extinction and renewal analyses used the 25 participants who had first acquired the differential urge response. At testing, the distinction between the availability and unavailability cues reappeared in the original learning room, but not significantly in the extinction room. The outcome was self-reported urge, not subsequent abstinence or relapse. The study therefore supports context-dependent responding in that experiment; it does not measure the probability that a person will smoke at an old workplace.
A reduced response is not necessarily an erased association
In learning terminology, extinction means that a previously learned response decreases when the expected outcome no longer follows the cue. It does not necessarily mean the original association has been deleted. New learning can be easier to retrieve in the context where it occurred, while another context makes an older expectation more relevant.
Renewal is narrower than ‘all cravings come back’. In this experiment, the key comparison concerned the difference between two cues. It was not proof that every participant’s entire urge returned to its starting level. Nor does a low response in room B prove that B would protect someone in everyday life.
A useful way to describe the problem when seeking support
‘My urge returned at the old doorway, but not during breaks elsewhere’ describes a specific difficulty more clearly than ‘everything has reset’. A qualified cessation professional can discuss that situation alongside other relevant circumstances. This explanation is not a recommendation to recreate the experiment, handle cigarettes, or deliberately visit a difficult place to test whether a memory has been erased.
In England, the NHS Better Health page links to local stop-smoking support. Ask the service about access and the support it offers. Elsewhere, use the relevant local health service. This site does not need your smoking history or the address of a difficult place.
