The purpose of this article is to describe parallels between Mandler's theory of conceptual development in infancy, and my theory of the maximum-power principle evolution of the neuro-algorithmic organization of the brain and cultural-level mental models. A maximum-power principle prey-predator scenario depicts the dynamic selective origins of neuro-algorithms underlying Mandler's various image-schemas (conceptual primitives). It is proposed that (a) image-schemas are inherited space-time simulation structures that originate in cerebellar state-estimating functions which spread to the mapping systems of the cerebrum; (b) image-schemas do not come about as the result of perceptual analytic abstractive processes as Mandler has proposed, but undergo refinement in ontogeny through experience-expectant development involving perceptual analysis; (c) Mandler's image-schemas are "state-primitives" fed forward from the cerebellum to provide tracking routines for perceptual analysis, and rapid simulations constituting representation, prediction, and control; and (d) vicarious trial and error (VTE) can be interpreted as pragmatic vector simulation using image-schematic simulation structures. A scenario connecting image-schemas with Pleistocene era auditory-vocal system evolution which supports Mandler's developmental connection between image-schemas and language is proposed. It is concluded that Mandler's theory of conceptual development is essentially correct. However, it is suggested that the further articulation of Mandler's theory would benefit from parallel statement of the evolution of underlying brain mechanisms. (C) 1997 Elsevier Science Ltd.
