Eleven participants in two experimental groups, DMTS-3s and DMTS-6s, trained conditional discriminations (AB, AC, CD, DE, and EF) with the potential emergence of three 6-member equivalence classes. The A stimuli (A1, A2, and A3) consisted of faces showing angry, neutral, and happy facial expressions, respectively. All participants responded in accordance with the experimentally defined criterion of 95% correct on two consecutive transitivity BF and equivalence FB test blocks. Next, participants rated the abstract D1 and D3 stimuli equivalent to the angry and happy faces (A1 and A3) on a Semantic Differential Rating Scale. A control group rated the facial stimuli and the abstract D stimuli on a similar rating scale. Results show that stimuli are more related when trained with DMTS-3s than DMTS-6s. Abstract D3 stimuli rated by the DMTS-3s group deviated less from control group ratings of respective faces than ratings of all other abstract D stimuli by the two experimental groups.
