Commitment in romantic relationships as a function of partners' encoding of important couple-related memories

The purpose of the present study was to investigate how significant couple-related events are encoded in the episodic memory of each partner of a romantic relationship and how they relate to each of these partners' level of commitment in an independent and additive fashion. Each partner of a couple reported a significant couple-related memory and rated their level of need satisfaction experienced during the event of the memory. In addition, each partner was shown his/her partner's memory and also rated their own level of need satisfaction for this event. Results showed that partners need satisfaction ratings of their own memory positively predicted their own commitment to the relationship directly (for women) as well as through their need satisfaction generally experienced in the relationship (for men). In addition, men's need satisfaction ratings of their own memory were associated with women's commitment while controlling for women's need satisfaction ratings of men's memory, but no such cross-partner effects were found for women. Overall, the findings shed light on an initial understanding of how a person's own memory of an event can impact another person's attitudes even when taking into account this other person's memory encoding of that same event.
