Implicit associative memory remains intact with age and extends to target-distractor pairs.

In this study, we use a novel, implicit memory paradigm to test forhyper-binding, or older adults' tendency to form non-target associations. Participants viewed pictures of objects superimposed with text and made speeded categorization judgments about the objects across three blocks varying in binding demand. During the no- and some-binding blocks, participants decided if the pictured object alone could fit inside a drawer while ignoring superimposed non-words and words, respectively. During the full-binding block, participants decided if both items could fit inside a drawer together. At test, participants viewed intact and rearranged pairs from encoding and decided if both items could fit in a drawer together. Across two experiments, older adults responded faster to intact than rearranged pairs from both the some- and full-binding blocks, while young adults showed no difference in RTs. These findings suggest that implicit associative memory is preserved with age and extends to non-target information.
