This study assessed the emergence of generalized equivalence classes, with the inclusion of specific reinforcers, by infants up to 24 months old. Auditory-visual relations (AB and AC) were taught, with specific consequences (D), for five infants aged between 18 and 20 months. Naming and emergent relations tests (BC, CB, AD, DE and EB, with B and E stimuli physically similar). Three participants demonstrated equivalence classes formation, including specific reinforcers (ABCD), and two of them presented consistent naming. Two participants demonstrated generalized equivalence classes. The results indicated the unprecedented formation of generalized equivalence classes with the inclusion of specific reinforcers in babies, and that naming may not be a necessary condition for the formation of classes.
