When familiar social partners are selected in open-ended situations: further tests of the socioemotional selectivity theory.

Socioemotional selectivity theory (SST; Carstensen, 1995, Current Directions in Psychological Science, 4, 151-156) predicts that novel social partners are preferred in open-ended situations, whereas familiar social partners are preferred in future-limited situations. The authors attempted to generalize past research to new familiar and novel partner options. Studies 1 (N=144; undergraduates, community-dwelling adults ages 65 to 95) and 2 (N=336 community-dwelling participants ages 11 to 89) indicated that young and older participants in a future-limited situation preferred familiar partners. However, with different social partner options than have been used in previous research, young participants in an open-ended situation also preferred a familiar partner, contrary to the predictions of SST.
