To me, one may think of stages of cognitive development in terms of complexity, and one may see complexity readily accommodates Robbie Case’s ideas about the role of increasing short-term memory span, which may be presumed to be due to brain maturation.? In my opinion, complexity does not replace Piaget’s schemes.?I think of the operative role of Piaget’s schemes?in the first three sensorimotor stages as primarily cumulative/assimilative of content or aliment, which results in schemes that are increasingly undifferentiated.?Thereafter, while assimilation is always operative to some extent, differentiation characterizes later stages or levels of scheme organization.?Such notions readily accommodate the timing of complete myelination of certain sensory tracts and the role of language in assisting formation of later cognitive stages. Although Piaget did not say so, it is hard to believe that he did not think that his schemes could readily be translated into neuronal circuitry.?In my books--The Conscious Mind and Development of the Mind and Brain—I detail how such a translation can be made. |
