Schizophrenic memory following an experimenter-imposed encoding task was examined in a levels-of-processing framework. In Session 1, 17 schizophrenics, 17 nonschizophrenics, and 17 normals were required to judge (yes or no) whether a probe word (a) contained two letters, (b) rhymed with a word, (c) belonged to a conceptual category, or (d) fitted into a sentence. In Session 2, they were required to produce an appropriate word for each question. The three groups recalled semantically processed words better than nonsemantically processed words and yes words better than no words and revealed similar recall and recognition patterns over the different levels of encodings. However, the schizophrenics' recall for yes words '(Session 1) and for the self-generated words (Session 2) was inferior to that of normals. Theoretical implications of these findings are discussed.A good deal of recent evidence suggests that the memory deficit of schizophrenic patients is a consequence of their deficient mnemonic strategies, especially inefficient encoding of the input material for memory storage and eventual retrieval (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
