socioemotional selectivity

Explanation:

Socioemotional selectivity theory is a life-span theory of motivation. The theory maintains that as time horizons shrink, as they typically do with age, people become increasingly selective, investing greater resources in emotionally meaningful goals and activities.

Socioemotional selectivity theory (SST) is a life-span theory of motivation grounded in the uniquely human ability to monitor time. In particular, the theory posits that age differences in goals result from shrinking time horizons. Goals influence social preferences and the composition of social networks. Because goals also direct cognitive processing, SST postulates that attention, memory, decision-making, and emotional experience are influenced fundamentally by the perception of time. Unlike most developmental theories of adulthood, which place primary emphasis on past experience, SST considers ways in which perceptions of the future change.
