Abstract: While equivalence is a well-documented phenomenon, its basis is of considerable debate. The current experiment looked at the effects of training structure and naming in the acquisition of conditional discriminations and equivalence-class formation. The experiment also looked to see if typicality effects would occur in children's equivalence classes and if so, whether it would be impacted differently by the different training structures. Four groups of children learned conditional discriminations using a match-to sample (MTS) procedure. The stimuli used were trigrams and one-to four-feature stimuli. Three different training structures were employed in the training, the one-to-many training structure using the trigram as the node, the many-to-one training structure using the trigram as the node and the many-to-one training structure using a two-feature stimuli as the node. Results showed that children learned the conditional discriminations more quickly in the many-to-one, two-feature-as-node training structure. The results also showed the formation of equivalence classes with different training structures. An analysis of typicality effects was also formulated.
