Abstract
Both inhibitory deficit and source monitoring theories of working memory (WM) decline
with age state that older adults should be more susceptible to interference. Hedden and
Park (2001b) presented evidence supporting both of these theories, but their experimental
design had a significant confound. The present study replicated the portion of Hedden &
Park's experiment in question. Participants were presented with three sets of words: one
set to remember, one set to read, and one set whose purpose was to test the participants'
recall for the previous sets. The hypothesis was evaluated using reaction time and
accuracy data as the dependent variables. The most important effect seen was that a
portion of older adults experienced interference in a WM task when they read interfering
information and were then later tested on that same information, providing strong support
for the source monitoring deficit view of age-related WM decline.
