Looking Back to Move Forward: Nostalgia as a Psychological Resource for Promoting Relationship Goals and Overcoming Relationship Challenges

Previous research has shown that nostalgia is a highly social emotion that provides a sense of social connectedness. In the present research, we tested a social motivational function of nostalgia. Specifically, across 7 studies we found converging evidence that nostalgia mobilizes social goals. In Study 1, nostalgia increased the importance people assigned to relationship goals and how optimistic they felt about achieving these goals. In Study 2, nostalgia increased intentions to pursue goals of connecting with friends. In Study 3, experimentally induced pessimism about achieving relationship goals instigated nostalgia. In Study 4, we found evidence that it is the interpersonal nature of nostalgia that is associated with striving to connect with others. Specifically, nostalgia about aspects of the past that were high in sociality was associated with intentions to interact with others, whereas nostalgia for aspects of the past that were low in sociality was not. In Study 5, nostalgic reflection increased friendship-approach goal striving relative to reflecting on ordinary social memories, but did not increase friendship-avoidant goal striving. Finally, in Studies 6 and 7, we found evidence that social-efficacy mediated the effect of nostalgia on striving to connect with others and striving to overcome interpersonal challenges. Together, these findings establish nostalgia as catalyst for social goal pursuit and growth.
