Abstract

Learning comparative relations ("more than", "less than", "bigger than", "smaller than") require the establishment of ordinal relations between stimuli. These repertoires have been investigated by an expansion of stimulus equivalence paradigm and also by Relational Frame Theory (RFT). Some studies have suggested that conceptual repertoires (nonarbitrary relational responding) may facilitate the acquisition of ordinal relations between arbitrary stimuli (arbitrary relational responding). However, we do not know if the concept formation at this context is necessary for the establishment of ordinal relations, as presumed by RFT. The present study aims to evaluate the effects of teaching the concept repertoires of "bigger than" and "smaller than" on learning ordinal relations between abstract stimuli of the same size in individuals with autism. Eight individuals who did not have the repertoires of "bigger than" and "smaller than" will participate. Half of the participants will be exposed first to AC and BC relations, between auditory words "bigger than" and "smaller than" (A), mathematical symbols ">" and "<" (B) and several stimuli of different sizes (C) as comparisons. The other participants will be taught only AB matching, between auditory samples "bigger than" and "smaller than" (A) and mathematical symbols (B) as comparisons. After that, all participants will be taught the ordinal relations D1>D2>D3>D4>D5 and D5D4, D4D5 and D5
