This study examined the distinction between identification
and production processes in repetition priming for 16 patients
with Alzheimer's disease (AD) and 16 healthy old control
participants (NC). Words were read in three study phases. In
three test phases, participants (1) reread studied words, along
with unstudied words, in a word-naming task (identification
priming); (2) completed 3-letter stems of studied and unstudied
words into words in a word-stem completion task (production
priming); and (3) answered yes or no to having
read studied and unstudied words in a recognition task (explicit
memory). Explicit memory and word-stem completion priming were
impaired in the AD group compared to the NC group. After correcting
for baseline slowing, word-naming priming magnitude did not
differ between the groups. The results suggest that the distinction
between production and identification processes has promise
for explaining the pattern of preservation and failure of
repetition priming in AD. (JINS, 2001, 7,
