Cognitivism (Mind)

Time, in the cognitivist picture, is registered through internal representations — the temporal indices on stored memories, the durational parameters of perceptual and motor routines, the scheduling logic of working memory and attention. It is not treated as a foundational metaphysical category but as a feature of the world about which the cognitive system maintains representations. The 'real-time' constraints on cognitive processing — reaction times, decay rates, the temporal grain of perception — are the cognitivist's distinctive contribution to the topic. What matters is how the system represents and operates over temporal structure.

Spatial cognition is a flagship topic for cognitivism: cognitive maps, mental rotation, allocentric and egocentric reference frames, the place- and grid-cells of hippocampal neuroscience. Space is treated as something the cognitive system represents and computes over, using formats that admit of precise psychological and neural investigation. The cognitivist is not committed to a particular metaphysics of physical space but to a rich account of how organisms internally model the spatial structure of their environments and navigate within them.

The cognitivist accepts the substantival materiality of brains and bodies as the physical realisers of cognitive processes — the mind is not a separate substance but the representational organisation of a particular kind of material system. The characteristic claim is that this organisation is multiply realisable: the same computational structure could in principle be implemented in different physical substrates, which is why cognitive explanation does not reduce to neuroscience even though it presupposes it. Matter matters because cognition has to be implemented somewhere; it does not exhaust what cognition is.

The cognitivist treats the observer as a representational system implemented in the brain — a structured architecture that encodes information about the world and operates on those representations to produce perception, deliberation, and action. Knowledge is the standing content of internal representations and the procedures that deploy them; the observer is embodied in the sense that this architecture is physically realised, but cognitive explanation operates at the representational level rather than at the level of neurons. Fodor's language of thought, Marr's three levels of analysis, and Chomsky's competence-performance distinction all express the central commitment: the mind is intelligible as a computational system whose operations are describable independent of any particular implementation.

Energy enters the cognitivist picture as a constraint on cognitive architecture: biological brains operate within tight metabolic budgets, and the costs of attention, memory maintenance, and inference shape what cognitive operations can realistically be performed in real time. Recent work on the 'free-energy principle' and on predictive processing has made energetic considerations more central, treating perception and action as means by which the system minimises long-run surprise and metabolic cost. Energy is not foundational for cognitivism, but it is the resource within which any plausible computational mind must operate.

Mental processes are computational operations on internal representations. The mind is the brain considered as an information-processing system; psychological explanation operates at the representational level.
