Abstract
A number of recent studies investigating (meta-)memory have detected that memory accuracy is decreased in schizophrenia and that at the same time patients hold false information with strong conviction. The aim of the present study was to test whether increasing meta-memory awareness (i.e., forewarning) could attenuate this pattern of results. Forty-seven schizophrenia patients and 47 healthy controls were administered two pictures of a visual false memory paradigm, one with forewarning and the second without. After both pictures, a recognition task required participants to make old-new discriminations along with confidence ratings. Results showed that, although the standard memory and meta-memory response patterns were replicated in this study, in which schizophrenia patients show decreased memory accuracy and knowledge corruption, the initial forewarning did not influence the robustness of these meta-memory deficits within schizophrenia patients.
