True and false autobiographical memories in schizophrenia: preliminary results of a diary study.
The frequency of true and false autobiographical memories and associated states of conscious awareness, i.e., conscious recollection and simply knowing, as well as the respective roles of affective and cognitive processes in autobiographical memory construction, were assessed in eight patients with schizophrenia and eight control participants. A diary study methodology was used in combination with the Remember/Know procedure. The results showed a higher frequency of Know responses associated with the retrieval of both true and false memories in patients than in control participants. Whereas control participants rated higher at retrieval than at encoding the distinctiveness and personal importance of events, as well as the extent to which events furthered current personal plans, patients exhibited an opposite pattern of ratings, with ratings being lower at retrieval than at encoding. These preliminary results show a high frequency of simply knowing associated with the retrieval of true and false autobiographical memories in patients with schizophrenia and provide evidence for the interest of the diary study methodology for studying autobiographical memory in schizophrenia.
