Experimental lure discrimination task. Note: Outline of lure discrimination task. During encoding, a daily life object is presented for 2500 ms and participants judge the nature of an object (“indoor” vs. “outdoor”). During retrieval, each object is again shown for 2500 ms. Participants first judge whether the object is “old” for targets, “similar” for lures, or “new” for foils. Next, for targets and lures, participants indicate in which quadrant the (original) was shown during encoding. For foils, participants judge how confident they are with their decision (“sure” vs. “unsure”). All images as well as the task are open access and freely available via (https://faculty.sites.uci.edu/starklab/mnemonic-similarity-task-mst/).
