The Memory Impairment In Schizophrenia

method of revised process dissociation procedure. In the experiment, there were three sessions, study and test, and an interruption task between study and test. Then calculated the R and A by the PDF function, and make comparisons among patients with these data.Results (1) Explicit memory impairment existed widely in schizophrenia, but implicit memory impairment only occurred under the concept driven experiment. (2)Sex differences didn't reach significant in explicit memory as well as implicit memory of four different experiment types. (3)The explicit memory results in patients with positive symptoms were higher than those with negative symptoms, but in implicit memory, the results did not differ remarkably. (4) There were no distinct correlations between positive symptoms and explicit memory results in the four experiments. There existed significant inverse correlations between negative symptoms and explicit memoryResults in the four experiments. There were no distinct correlations between positive, negative symptom and implicit memory in the four experiments. Conclusions (1) Explicit memory impairment in schizophrenia was widespread, but implicit memory impairment only displayed in concept driven experiment. (2)Explicit memory impairment was prominent, especially in patients with negative symptoms. But implicit memory impairment was independent from the positive, negative symptoms. (3)Sex differences in explicit and implicit memory don't appear in the schizophrenia patients. Objective To explore the explicit memory and implicit memory impairment in schizophrenia, then make comparisons among patients with different subtypes of schizophrenia in this aspect. Methods Fifty-nine patients with schizophrenia and forty normal controls were tested in word perceptual driven experiment, word concept driven experiment, image perceptual driven experiment, image concept driven experiment separately, in the...
