The equivalence paradigm has been useful in the explanation of complex behavioral processes like those involved in numeric conceptual behaviors. Several studies have looked for a comprehension of how performances under control of order are established and maintained. The purpose of the present study was to verify if ordinal classes could emerge following arbitrary matching to sample (AMTS) and sequence production. Three students with developmental disabilities participated of the study. The visual stimuli were abstract forms in different quantities (A), cardinal numbers (B), and written word in capital letters (C). The experimental sessions were conducted in a room of APAE-BELÉM and a software controlled and recorded the behavioral data. The AB/AC relations were trained and the emergence of three equivalence classes was tested. After the forward chaining procedure to teach one sequence (A1A2A3), the emergence of novel sequences was assessed (e. g. B1B2B3 and C1C2C3). Substitutability tests assessed the ordinal classes formation (e.g. A1B2C3). Generalization tests also were presented in order to verify if a response involving numerosity would occur with new stimuli. Results showed that the participants responded to novel sequences readily or with gradual emergence. The stimulus control topography analysis in that kind of task was helpful to the comprehension of the ordinal relations. All participants responded to sequences with new stimuli. The procedure was also effective in the transfer of ordinal functions in people with developmental disabilities.
