Dissociation of processes in belief: Source recollection, statement familiarity, and the illusion of truth.

Reports 4 experiments concerning the effect of repetition on rated truth (the illusory-truth effect). Statements were paired with differentially credible sources (true vs false). Old trues would be rated true on 2 bases, source recollection and statement familiarity. Old falses, however, would be rated false if sources were recollected, leaving the unintentional influence of familiarity as their only basis for being rated true. Even so, falses were rated truer than new statements unless sources were especially memorable. Estimates showed the contributions of the 2 influences to be independent; the intentional influence of recollection was reduced if control was impaired, but the unintentional influence of familiarity remained constant.
