Programa de Pós-Graduação em Teoria e Pesquisa do Comportamento.https://repositorio.ufpa.br/handle/2011/5358Studies first realized on the UFPA Psychology Experimental Laboratory showed that the chaining trial was more efficient on the sequential classes formation demonstrating a better precision by the participants on the test that documented the ordinal relation properties, specially on the substitutability test. Based on this study and through a chaining procedure to form eight independent sequences with visual stimuli, it was looked to evaluate the effects of a trial history with usual stimuli and no usual ones, and if the emergent sequential classes members were also equivalents. Participated on this study three people with mental retardation, students from APAE (Associação de Pais e Amigos dos Excepcionais). All of them were experimentally naïve. The experimental sections were realized in an APAE classroom, five times a week. It was used a computer with sensible touch screen that was specially created to this study. The procedure counted with trial and tests phases, and was divided in two conditions: in the Condition I it was used the answer chaining trial with four usual stimuli groups followed by the sequential test, no adjacent pair of stimuli tests, stimuli substitutability and equivalence test. In the Condition II it was used the same procedure used in Condition I with four new no usual stimuli groups. The results showed that the taught sequences presented an ordinarily relation properties during the stimuli substitutability tests. The participants were capable to form a new sequence by the two sequences independent trial, suggesting the sequential class emergency in both experimental conditions demonstrating that the usual stimuli could be exercised an ordinarily basic function, and had facilitated the sequential answer with the new stimuli. The equivalence relations emergency suggests also that the stimuli are functionally equivalents. These results make bigger anterior studies results to other population and empirically confirm what have being appointed by this subject literature.porAcesso AbertoPsicologia experimentalEquivalência de estímulosEstímulo/respostaRelações entre estímulosEducação especialPortadores de necessidades especiaisBelém - PAPará - EstadoAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS HUMANAS::PSICOLOGIA::PSICOLOGIA EXPERIMENTAL
