The «bonding» and «attachment» relationship developed between the hearing parents who use the spoken language with his deaf child is quite different from the one developed between deaf parents and his also deaf child. The results are different: the first parents have a soliloquy relationship where as the second ones have an interaction relationship. Also the development of the linguistic interaction has a different relation in each of the referred groups: those using the sign language develop the linguistic communication at all stages - syntax, morphology and semantics - while children using spoken language don't have that possibility. These facts induced us to make a study about the cognitive development between the two groups of deaf children: one whose parents could hear and another whose parents are deaf. The concepts of perception, action (sensory-motor and which we name «empirical abstraction»), operation (as a result from the conceptual construction - «reflexive abstraction») help the individual to get a conceptual net of coherent structures. The important about cognitive development is the capability of making reflexive abstractions - mental operations. The sensory-motor experience is expressed by actions while the conceptual one is expressed through symbols.
