Training Subsets 2 and 3 was the same except that different samples were used: A3B3, A1C1, A2B3
, A3B2, A1C3, A3C1 (Subset 2), and A2B2, A3C3, A1B2, A2B1, A2C3, A3C2 (Subset 3).
Thus when given A2B3
, the subjects selected C1 because A2B3
had no element in common with A1B1.
For example, in the trained baseline relations, A1B1, A2B3, and A3B2 controlled selection of C1.
Class One = C1, A1B1, A2B3, A3B2) and that the C stimulus and the A and B stimuli within a given compound were substitutable for one another.
In the case of Participant 1, the S- stim uli were A2B3 and A3B1 .
