This chapter describes a multimotive model of responses to rejection-related experiences. Social exclusion, like other forms of rejection, represents a threat to our need to be valued and accepted by others. In response to social exclusion, people often experience three sets of motives that promote competing behaviors: to aggress against the source of rejection, repair the relationship, and withdraw. According to the multimotive model, the ways in which the exclusion is construed determines when each of these behaviors are most likely to occur. The various construals are described in the context of different rejection-related experiences, and the model is applied to understand some of the long-term mental and physical health consequences of unrestored belonging.
