“…Above each word puzzle, a short written verbal clue in green font was provided to disambiguate the puzzles (e.g., furniture ). The methodology for this task was adopted from a pilot project (Woodward, Whitman, Cuttler, & Moritz, 2003). Participants were familiarized with the procedure that, in alternating order, the word puzzles should be solved either by the participant or the computer, which was indicated by a brief computer display ( Please name the next item or The next item will be read to you ).…”

A number of recent studies have demonstrated that individuals with schizophrenia display knowledge corruption; that is, they hold false information with strong conviction. This aberration in metamemory is thought to stem from poor memory accuracy in conjunction with impaired discrimination of correct and incorrect judgments in terms of confidence. Thirty-one participants with schizophrenia, along with 61 healthy control participants and 48 control participants with other psychiatric conditions, participated in a computerized source memory task. Whereas no differences in memory accuracy were observed between the group with schizophrenia and the group with other psychiatric diagnoses, knowledge corruption was specifically impaired in those with schizophrenia. Schizophrenia participants showed a significantly decreased confidence gap: They were more confident in errors and less confident in correct responses relative to those in the control groups. Knowledge corruption is theorized to be a potential risk factor for the emergence of delusions.
