Abstract
After learning to choose the middle sized of three squares, 16 cats and 14 rhesus monkeys manifested much less generalization of response on 10 equivalence tests than 16 control cats trained to select the smallest or the largest of three stimuli. These results are more compatible with Spence’s theory of transposition than with relational theories of transposition.
