Is associative recognition more impaired than item recognition memory in Schizophrenia? A meta-analysis.
Item recognition memory judgment can be based on two processes: item familiarity and/or the conscious recollection of the initial event. On the other hand, associative recognition relies preferably on conscious recollection. Since evidence points to a specific deficit of conscious recollection in schizophrenia, these patients could show greater impairment during associative recognition tasks relative to item recognition tasks. A meta-analysis of 23 studies of recognition memory in schizophrenia was conducted to test this hypothesis. The impairment is indeed 20% greater (p=0.04) for associative recognition relative to item recognition. This study supports the hypothesis of a specific conscious recollection deficit underlying episodic memory impairment in schizophrenia.
