Two experiments investigated whether differential outcomes in matching-to-sample (MTS) would enhance acquisition even in cases in which the outcomes could not be anticipated at the beginning of a trial. In Experiment 1, food and no-food outcomes were differential with respect to both hue and line comparisons in one-to-many matching-to-sample (MTS) but were nondifferential with respect to the samples. Overall acquisition and acquisition with each comparison set were faster in relation to controls that received each outcome equally often on all trials. In Experiment 2, hue and line comparisons were associated with either different probabilities of food (p = 1.0 vs. 0.2) or with the same probability (p = .6). Again, matching acquisition was more rapid in the differential group. These data demonstrate that differential comparison-outcome associations are sufficient to enhance conditional discrimination learning.
