Pre-requisitos ontogenéticos para la emergencia de relaciones simétricas

When working with humans using conditional discriminations the formation of equivalence classes is obtained systematically. Nevertheless, the existence of this type of relations in nonhuman subjects still has not been demonstrated of unequivocal form. We can consider these differences between humans and animals of qualitative (phylogenesis) or quantitative (ontogenesis) nature. If we assumed the quantitative option we will have to demonstrate the existence of some previous learning that the human community would offer us and that would act like the pre-requisite for the later emergence of discriminative control relations not directly trained. In the present work the exemplars theory , the formation of functional classes and the discrimination of the one´s own behavior are examined as explanatory hypotheses. Finally, we also presented preliminary data that support the one´s own behavior proposal.
