Is sharing specific autobiographical memories a distinct form of self-disclosure?

Theories of autobiographical memory posit a social function, meaning that recollecting and sharing memories of specific discrete events creates and maintains relationship intimacy. Eight studies with 1,271 participants tested whether sharing specific autobiographical memories in conversations increases feelings of closeness among conversation partners, relative to sharing other self-related information. The first 2 studies revealed that conversations in which specific autobiographical memories were shared were also accompanied by feelings of closeness among conversation partners. The next 5 studies experimentally introduced specific autobiographical memories versus general information about the self into conversations between mostly unacquainted pairs of participants. Discussing specific autobiographical memories led to greater closeness among conversation partners than discussing nonself-related topics, but no greater closeness than discussing other, more general self-related information. In the final study unacquainted pairs in whom feelings of closeness had been experimentally induced through shared humor were more likely to discuss specific autobiographical memories than unacquainted control participant pairs. We conclude that sharing specific autobiographical memories may express more than create relationship closeness, and discuss how relationship closeness may afford sharing of specific autobiographical memories by providing common ground, a social display, or a safety signal.
