How Hirsch uses it
Every occurrence, grouped by book and chapter, with the claim it was linked to support and (where the extraction regenerated one) the underlying warrant.
1987 · Cultural Literacy
Reaction time measurements for verifying sentences like 'A robin is a bird' versus 'A chicken is a bird.'
direct Category prototypes are processed much faster than atypical examples when verifying statements.
Warrant (implicit): The speed of a mental response is a direct indicator of the degree of alignment between an external stimulus and an internal mental prototype.
could fail ifReaction time differences could be caused by the word 'robin' being shorter and more common (higher word frequency) than the word 'chicken', rather than their relative 'typicality' as birds.
2022 · American Ethnicity
Rosch's sentence substitution experiment where subjects judged the 'sense' of sentences when class names were replaced with typical vs. atypical members.
direct Sentences using a general class name are perceived as making sense only if the specific member substituted for that class name matches the typical behavior of the class prototype.
Warrant (implicit): The perceived logical coherence of a sentence depends on the degree to which specific referents align with the prototypical characteristics of the category mentioned.
could fail ifSubjects may be reacting to the statistical probability of the event described rather than the semantic structure of the category itself.
Reaction time data showing subjects take longer to verify atypical members of a class (e.g., 'A chicken is a bird') than typical members.
direct Prototypes of categories are processed significantly faster by the brain than atypical examples.
Warrant (implicit): Faster cognitive processing times for specific category members are a direct measure of their status as mental prototypes.
could fail ifReaction times are heavily influenced by the word's frequency in common usage, which may not be synonymous with its status as a 'prototype'.
