      Personality predicts how we interact with others, what partners we have, and how happy and lasting our romantic relationships are. At the same time, our experiences in these relationships may affect our personality. Who experiences specific major relationship events, and how do these events relate to personality development? We examined this issue based on data from a nationally representative household panel study from Germany (N = 49,932). In this study, the occurrence of major relationship events (moving in with a partner, marriage, separation, and divorce) was assessed yearly, and the Big Five personality traits were measured repeatedly in 2005, 2009, 2013, and 2017 with the short version of the Big Five Inventory. We applied multilevel analyses to simultaneously model selection effects as well as different types of personality changes in the years before and after these events in the total sample and separately in women and men. Our findings revealed that less agreeable individuals were more likely to experience each of the examined relationship events. Moreover, each event was associated with personality changes, which only occurred after (not before) these events and considerably varied by event and gender. Individuals who moved in with a partner, got married, or separated from a partner primarily experienced changes in openness in the first year thereafter, and individuals who separated from a partner or got divorced became less emotionally stable in the following years. However, there was little evidence for "maturation" effects, except that individuals who moved in with a partner (especially men) became more conscientious in the following years.

      Many everyday conversations, whether between close partners or strangers interacting for the first time, are about the world external to their relationship, such as music, food, or current events. Yet, the focus of most research on interpersonal relationships to date has been on the ways in which partners perceive each other and their relationship. We propose that one critical aspect of interpersonal interactions is developing a sense of dyadic, generalized shared reality-the subjective experience of sharing a set of inner states (e.g., thoughts, feelings, or beliefs) in common with a particular interaction partner about the world in general, including the world external to the relationship. Across 9 studies, we use mixed methods to investigate the unique role of generalized shared reality in interpersonal interactions, both between close partners and strangers. We hypothesize that generalized shared reality predicts how people connect with each other and perceive the world around them. We also investigate the observable, dyadic behavioral signatures of generalized shared reality in interpersonal interactions. Finally, we examine the motivation to uphold an existing sense of generalized shared reality. We hypothesize that couples high on baseline generalized shared reality exhibit motivated, dyadic interaction behaviors to reaffirm their generalized shared reality in the face of experimentally manipulated threat. By identifying a unique dimension of everyday interactions, these studies aim to capture a critical aspect of the lived subjective experience of human relationships that has not been captured before.
