Previous equivalence-class formation studies, with class-specifi c consequences, found inter-subject variability, probably due to loss of effi cacy of the consequences as reinforcers. This study evaluated (a) the effi cacy of introducing variations of events (within a category) as class-specifi c consequences and (b) the inclusion of these consequences into the equivalence classes. Two children diagnosed with Autism Spectrum Disorder (ASD), and with intellectual disabilities, were given

Two sets of assorted videos on the same theme plus two sets of assorted food items within the same category were used as class-specifi c consequences. The data show that the variety of elements was effi cient to maintain reinforcement effi cacy and encourage the use of similar procedures in the applied context. Both participants showed strong evidence of equivalence class formation, confi rming the theoretical prediction regarding the inclusion of the class-specifi c consequences in the classes. The data confi rm that equivalence relations can be found in three-term contingencies.
