Jde. Gabrieli et al., Convergent behavioral and neuropsychological evidence for a distinction between identification and production forms of repetition priming, J EXP PSY G, 128(4), 1999, pp. 479-498
Four experiments examined a distinction between kinds of repetition priming
which involve either the identification of the form or meaning of a stimul
us or the production of a response on the basis of a cue. Patients with Alz
heimer's disease had intact priming on picture-naming and category-exemplar
identification tasks and impaired priming on word-stem completion and cate
gory-exemplar production tasks. Division of study-phase attention in health
y participants reduced priming on word-stem completion and category-exempla
r production tasks but not on picture-naming and category-exemplar identifi
cation tasks. The parallel dissociations in normal and abnormal memory cann
ot be explained by implicit-explicit or perceptual-conceptual distinctions
but are explained by an identification-production distinction. There may be
separable cognitive and neural bases for implicit modulation of identifica
tion and production forms of knowledge.
