concepta

Concepta is a term used in some strands of cognitive science and philosophy to refer to the internal mental representations that underlie concepts and category knowledge. In this use, a concepta is the content of a concept—the abstract structure that enables recognition, inference, and generalization—distinct from the particular objects it applies to (the exemplars) and from the linguistic label used to name it.

The form concepta is sometimes presented as a plural to emphasize content rather than surface form, though many authors use concept or concept content instead. The idea places concepta at the core of understanding how people categorize the world: they are the stable, underlying meaning that guides judgments, even as appearances and contexts shift.

Theorists debate how concepta are organized, with proposals ranging from feature lists and prototypes to distributed representations in neural networks. Concepta are thought to be dynamic: they can update with experience, incorporate causal relations, and integrate multi-modal information (visual, verbal, affective). In research, concepta are inferred from behavioral data, such as typicality judgments and categorization speed, and from neural patterns identified through imaging and electrophysiology, as well as from computational models that simulate concept formation.

Critics argue that "concepta" is an underspecified term and that clarification is needed on its relation to concepts, labels, and cognitive processes. Despite variations, the term captures a common aim: to describe the content that endows mental categories with meaning beyond mere labels.
