The education of deaf people in Brazil, regards the Brazilian Sign Language (LIBRAS) as the first language and written Portuguese Language as the instrumental language. The acquisition of the written language may be more difficult than the acquisition of LIBRAS due to the differences between their ordinal - grammatical structures. The ordinal - grammatical structure of the written Portuguese consists in a subject - verb - preposition - complement order, whereas the structure of the LIBRAS does not specify an order. Such differences usually result in a writing repertoire that has a different grammatical order than that one used by their verbal community. This study investigated variables that control the transfer of ordinal functions through classes of equivalent stimuli. The experimental stimuli used were 32 printed words divided into four stimuli categories (A1A2A3A4; B1B2B3B4; C1C2C3C4 e D1D2D3D4), corresponding to subject, verb, preposition/article and complement, respectively. The categories were taught through matching-to-sample (MTS) tasks, while the sequences were taught through constructed-response matching-to-sample (CRMTS). All participants showed the formation of four stimulus classes, and learned one sequence (A1A2A3A4). After that, they showed the transference of ordinal functions to untaught sequences. In summary, results showed the transference of ordinal functions through equivalence classes.
