Perception is often analysed as a process in which causal events from the environment act on a subject to produce states in the mind or brain. The role of the subject is an increasing feature of neuroscientific and cognitive literature. This feature is linked to the need for an account of the normative aspects of perceptual competence. A holographic model is offered in which objects are presented to the subject classified according to rules governing concepts and encoded in brain function (...) in that form. This implies that the analysis of perception must consider not only the fact that there is an interaction between the perceiving subject and the perceived object but also that the interaction is shaped by a system of concepts which the subject uses in thought and action.

Examines the theses that the postulation of mental processing is unnecessary to account for our perceptual relationship with the world, see turvey etal. for a criticque.

Concepts are basic elements of thought. Piaget has a conception of the nature of concepts as informational or computational operations performed in an inner milieu and enabling the child to understand the world in which it lives and acts. Concepts are, however, not merely logico?mathematical but are also conceptually linked to the mastery of language which itself involves the appropriate use of words in social and interpersonal settings. In the light of Vygotsky's work on the social and interactive nature of (...) children's thinking and the nature of language as an essentially public currency of rule?governed signs, we are led to reconstrue conceptual mastery as the acquisition of an interactive and interpersonal repertoire of tools which introduces the child to the world of those who educate it. In this way we come to see the elements of mind as constitutively involving that activity in which the determinants of meaning constrain and direct the child's linguistic development. (shrink)
