Abstract: ObjectivesIt is well known that age differentially impacts aspects of long-term episodic memory (EM): Whereas a binding deficit indicates that older adults are less capable than younger adults to encode or retrieve associations between information (e.g., the pairing between two memoranda, such as lock – race), item memory is relatively intact (e.g., recognizing lock without its original pairing).MethodWe tested whether this deficit could be corrected by facilitating establishment of the bindings in working memory (WM) through adapting the semantic relatedness of studied pairs according to participants’ ongoing performance (Experiments 1 and 2). We also examined whether this was evident for the long-term retention of pairs that were not tested in WM (Experiment 2).ResultsThe results revealed matched binding and item memory in WM and EM between age groups. Most importantly, older adults required increased semantic strength between word pairs to achieve similar performance to that of younger adults, regardless of whether pairs were immediately tested during the WM task.DiscussionThese findings indicate that relying on their superior semantic memory can correct the commonly exhibited profound deficit in binding memory in older age.
