ABSTRACT
As we saw in the introduction to Chapter VI, the present state of our knowledge suggests that there are two likely genetic hypotheses concerning the relations between perception and intelligence. The first is of a direct filiation from perceptual field effects to operational structures, through perceptual and sensory-motor activities and finally through perceptual representations. The second is of an autonomous development of intelligence from action (sensory-motor activities), accompanied by a continuous enrichment of perceptual structures under the influence of the development of structures of action and of intelligence. The latter would again be achieved (but in an inverse direction) through perceptual activities and would be accompanied by a progressive sedimentation of perceptual activities into field effects.
