The authors' theoretical analysis of the dissociation in amnesia between ca
tegorization and recognition suggests these conclusions: (a) Comparing to-b
e-categorized items to a category center or prototype produces strong proto
type advantages and steep typicality gradients, whereas comparing to-be-cat
egorized items to the training exemplars that surround the prototype produc
es weak prototype advantages and flat typicality gradients; (b) participant
s often show the former pattern, suggesting their use of prototypes; (c) ex
emplar models account poorly for these categorization data, but prototype m
odels account well for them; and (d) the recognition data suggest that cont
rols use a single-comparison exemplar-memorization process more powerfully
than amnesics, By pairing categorization based in prototypes with recogniti
on based in exemplar memorization, the authors support and extend other rec
ent accounts of cognitive performance that intermix prototypes and exemplar
s, and the authors reinforce traditional interpretations of the categorizat
ion-recognition dissociation in amnesia.
