We review research on the fluency heuristic as a basis for the subject
ive experience of familiarity. Then, we explore the links between the
construct of fluency and the automatic versus consciously controlled m
emory processes that are estimated using the process dissociation proc
edure, and the phenomenological experiences studied using ''Remember''
and ''Know'' judgements. Although the fluency that underlies familiar
ity may map onto the automatic memory process that is estimated by the
process dissociation procedure, both fluency and automatic memory pre
cesses arise in a particular context and their expression depends on t
he joint constraints created by the cues and the task. (C) 1998 Elsevi
