摘要：Pilgrim and Galizio (1995) reversed baseline conditionaldiscriminations after the emergence of equivalence classes.College students' performance was consistent with the reversedbaselines in subsequent symmetry tests, but was consistent withpre reversal baselines in transitivity tests. The present studyreplicated systematically Pilgrim and Galizio's experiment.Following the emergence of two four-members equivalenceclasses, 9 college students were exposed to reversal of a baselineconditional discrimination, training of a new conditionaldiscrimination, reversal of another baseline conditionaldiscrimination, and return to the original baseline. Both symmetryand transitivity performances were consistent with the reversedbaselines for most participants. These results may be due toincreased strength of the reversed baselines, trained withcontinuous reinforcement and reviewed before probes, whereasPilgrim and Galizio trained reversals with intermittentreinforcement in the context of probing. The use of different stimuliand stimulus display may have also affected the results.
