Mnemonic similarity task. (A) Participants view a sequence of objects during an incidental encoding phase in which participants classify each object as an indoor or outdoor object. (B) In a surprise discrimination test, participants view a series of objects and are asked to determine whether each object is “old,” “new,” or “similar” relative to the items that were shown during the encoding phase. (C) Correlation between age and lure discrimination scores (LDI) for each experiment. Shaded bands indicate 95% confidence intervals around the trendline.
