What we know as the self is not just one unified construct, but consists of various self-concepts that are continuously created, revised, and discarded, such as “woman”, “Thai national”, “Northwestern student”, and “true self”. These rich, variegated self-concepts help organize our endeavors throughout the different domains of our lives. How do we store information associated with each of these self-concepts without confusing them in long-term memory? We uncover two mechanisms that support this ability— one that arises from the nature of long-term memory processing, and the other that arises from the nature of self-referential processing. Specifically, people are less likely to confuse memories for self-concepts that are more distinct, and they are more likely to remember information for the self than for others. Together, the studies shed light on the mechanisms that support our impressively rich store of self knowledge.
