Stimulus control topography coherence theory: foundations and extensions.
Make sure the stimulus features you think are controlling behavior really are what the learner is noticing.
01Research in Context
What this study did
Madden et al. (2003) wrote a theory paper. They asked why some discrimination lessons fail even when the plan looks perfect.
They built stimulus-control topography coherence theory. It says trainers must check that the learner notices the exact features the trainer planned to use.
What they found
The paper gives no new data. It links old lab results into one warning: if the learner's controlling features differ from yours, performance will break down later.
It also lists test methods so you can catch the mismatch early.
How this fits with other research
MOORHEARSKELLEHER et al. (1964) showed preschoolers really used brightness, not form, during fading. The 2003 theory explains that classic result: brightness was the true topography.
Harrison et al. (1975) found pigeons trained without errors still formed S- control. The theory reframes this: the birds discriminated unnoticed features in the negative stimulus.
Boyle et al. (2021) later tested arbitrary versus natural cues in FCT thinning. Their mixed outcomes match the theory: arbitrary cues sometimes align better with the learner's actual topography.
Why it matters
Before your next discrimination program, probe what the client actually sees. Run a quick test with feature changes. If the learner only tracks color while you think they track shape, reshape the materials or add extra training on the intended cue. This five-minute check can save weeks of puzzling errors.

03Original abstract
Stimulus control topography refers to qualitative differences among members of a functional stimulus class. Stimulus control topography coherence refers to the degree of concordance between the stimulus properties specified as relevant by the individual arranging a reinforcement contingency (behavior analyst, experimenter, teacher, etc.) and the stimulus properties that come to control the behavior of the organism (experimental subject, student, etc.) that experiences those contingencies. This paper summarizes the rationale for analyses of discrimination learning outcomes in terms of stimulus control topography coherence and briefly reviews some of the foundational studies that led to this perspective. We also suggest directions for future research, including pursuit of conceptual and methodological challenges to a complete stimulus control topography coherence analysis of processes involved in discriminated and generalized operants.
