The role of schematic support in age-related associative deficits in short-term and long-term memory

Publication date: February 2017 Source:Journal of Memory and Language, Volume 92 Author(s): Dwight J. Peterson, Nicholas E. Schmidt, Moshe Naveh-Benjamin Older, relative to younger adults, exhibit an associative memory deficit in short-term and long-term memory, characterized by difficulty in binding distinct components to form associations, while item memory remains largely intact. Reduced performance emerges mostly due to high false alarm rates in older adults’ associative memory. One factor that could increase older adult false alarm rates during associative recognition memory tests is a decreased use of recollection processes that allow the rejection of recombined components from the study phase. The current experiments assessed the degree to which an increase in the use of semantic memory (schematic) support, by changing the patterns of support from study to test, can help older adults reduce their associative false alarms using recollection. In two experiments, face–name pairs were presented to younger and older adults. During a continuous recognition task assessing memory performance at short-term and long-term memory retention intervals, younger and older adults were tested on individual faces, names, and face–name pairs that either remained intact or were recombined within the same (e.g., old-face, old-name) or between two different age categories (e.g., old-face, young-name). In Experiment 2, we also collected “remember–know” judgments after re...
