Primes¶
- Prototype Theory
- Cognitive science and psychology. The foundational experiments on basic-level categorization showed that subjects judge typicality in graded terms, retrieve central exemplars faster, and treat fuzzy boundaries as normal rather than as definitional failure.
This sourceDemonstrates graded typicality, faster verification of central exemplars, and prototype structure in natural categories.

Mechanisms¶
- Graded Membership Table
- Its strength is honesty about degree: it stops a fuzzy category being forced into a true/false column, keeps the marginal cases visibly marginal, and puts the centre where everyone can see it — the graded-membership and typicality structure prototype categories actually have.
This sourceShows that semantic categories have internal typicality structure, with good and poor members affecting recognition differently.

- Typicality Rating Exercise
- This mirrors the classic finding that people rate a robin a more typical bird than a penguin even though both are fully, unquestionably birds.
This sourceUses robin and penguin as high- and low-typicality examples within the same bird category.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 3 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
