Context specificity of operant discrimination performance in pigeons.
The physical room is the main context cue, so teach new skills in every place you want them used.
01Research in Context
What this study did
Researchers worked with pigeons in two small chambers.
Each chamber had a different smell.
The birds first learned to peck left when the light was red and right when it was green.
Then the rule flipped: red now meant peck right and green meant peck left.
The smell was supposed to tell the birds which rule was in play.
Finally, the birds were moved to the other chamber to see if the smell alone would guide them.
What they found
The pigeons kept the new rule only in the chamber where they learned it.
When placed in the other chamber, they went back to the old rule even though the smell was correct.
The physical room mattered more than the odor cue.
How this fits with other research
LeFrancois et al. (1993) ran the same setup two years later and got clearer results.
They proved that smell plus the look of the chamber together create strong context control.
Storch et al. (2012) took the idea further.
They showed that teaching a new response in a separate room later helps reduce relapse when the bird returns to the original room.
All three studies agree: the room itself is a powerful cue that can override added signals like odor.
Why it matters
When you teach a child a new skill, the room where you teach it is part of the lesson.
If you want the skill to move to a new place, practice it there too.
Don’t rely on a single added cue like a scented sticker or a special song.

03Original abstract
In an experiment designed to investigate odors as potential retrieval cues in pigeons' memory (i.e., as conditional stimuli), 8 pigeons first learned to peck a red keylight (S+, reinforced) and not a blue one (S-, extinguished) in the presence of either a eucalyptus oil or isoamyl acetate odor. They were repeatedly switched between two chambers with the same odor to habituate any reaction to the switching that would be required for eventual testing for conditional control by the odors. Next, the birds learned the reversal (blue S+, red S-) in the presence of the alternative odor in one of these chambers. When the birds were then switched to the alternative chamber for additional training, although the odor was still appropriate to the reversal problem, behavior appropriate to the original training condition recurred. Testing indicated that reversal performance was specific to the one chamber in which it had been trained.
