conceptan

Conceptan is a theoretical construct used to describe how intelligent agents form and manage abstract ideas by integrating perceptual inputs with prior knowledge. In this framework, a conceptan represents not a single idea but a dynamic, multi-layered structure that can flexibly combine sub-concepts into context-appropriate meanings.

Originating in discussions of concept formation and embodied cognition, the term conceptan was coined in the early 2020s by researchers exploring how people adapt concept granularity to different tasks. The word blends "concept" with the suffix -an to indicate a participial or systemic unit rather than a fixed label.

Conceptans comprise three features: compositionality, allowing sub-concepts to be recombined; contextual modulation, tuning activation based on goals and environment; and dynamic refinement, updating structure as new data arrives. Activation spreads through a network of intermediate representations, enabling both generalization and discrimination without requiring a separate symbol for every possible articulation.

In cognitive science and artificial intelligence, the conceptan model offers a framework for explaining how humans adapt concepts to novel contexts and how learning systems can maintain stable yet flexible representations. In education, conceptans provide a way to illustrate how students can refine broad categories into precise definitions through guided context.

Critics argue that conceptan remains abstract and difficult to measure empirically, with challenges in operationalizing its components and distinguishing them from existing models of schemas and prototypes. Ongoing work seeks to establish testable predictions and computational implementations.
