Two diarists recorded true and false events and thoughts over a period
of 5 months. In recognition tests taken 7 months later, they discrimi
nated between true and false diary entries and judged their state of m
emory awareness as recollective experience, feeling of familiarity, or
no distinct state of awareness. Correct recognition rates for true ev
ents and thoughts were high. Events were associated with recollective
experience and thoughts with feelings of familiarity. Incorrect recogn
ition was higher for thoughts than events. False memories were associa
ted with familiarity or no distinct state of awareness. For correct me
mories of events only, factors influencing encoding (importance, conse
quentiality, etc.) interacted with state of memory awareness at retrie
val. The quality of phenomenal experience, based on the associations b
etween encoding and retrieval, may be critical in leading a rememberer
to accept a memory as true.
