Reliance on schemas in source memory: age differences and similarity of schemas.

The present study has examined the effects of source-schema-consistency, schematic distinctiveness and encoding time of schematic information on source memory of younger and older adults. Participants were administered a source memory test, in which two sources presented statements that were congruent with, incongruent with or irrelevant to sources' professions. Professions of sources were schematically similar or distinct, and they were revealed before or after the presentation of items. The results yielded that revelation of profession information before presentation of items enhanced source memory for incongruent items. Aging was associated with a general decrease in source monitoring processes. Participants who were assigned to similar-source condition and had their schemas activated before learning phase had higher source monitoring scores. Results are discussed in relation to source monitoring framework and aging of memory.
