Specific autobiographical memories are a resource for identity strength among mature but not emerging adults

Four studies, three pre-planned on Open Science Framework, with 2296 participants explored the potential role of recollecting autobiographical memories in enhancing the sense of identity. Among emerging adults (college students under age 25), recollecting important autobiographical memories did not strengthen sense of identity. Autobiographical memories failed to strengthen identity among emerging adults despite inducing low self-clarity first; despite attempts to prime self-consistent memories by having emerging adults report their stable self-aspects first; and despite attempts to inspire self-event connections by asking emerging adults to explain how the memories exemplified something enduring about the self. Among mature adults (age 25 and older), recollecting important autobiographical memories strengthened sense of identity. Identity was strengthened regardless of whether mature adults were asked to explain how the memories exemplified something enduring about the self. Differences in types of memories or motivation did not account for the differential effects of recollecting autobiographical memories in identity. In short, mature adults appear to readily use autobiographical memories as a resource for identity in a way that emerging adults have not yet mastered.
