The role played by similarity in discrimination learning was examined in four experiments using compound stimuli. In Experiment 1, pigeons received training in which food was presented after stimulus A, compound AB, but not compound ABC—A+ BC+ ABCo. The A+ ABCo discrimination was acquired more readily than was the BC+ ABCo discrimination. In the remaining experiments, training was of the form, A+ B+ C+ AB+ AC+ BC+ ABCo. The discrimination between the single stimuli A+ B+ C+ and ABCo consistently developed more readily than between the pairs of stimuli AB+ AC+ BC+, and ABCo. The results are shown to be more consistent with a configural than with an elemental theory of conditioning.
