In 2 studies the postulate that the perception of time left in life in
fluences the ways that people conceptualize social relationships was e
xplored. It was hypothesized that when time is limited, emotional aspe
cts of relationships are highly salient. In Study 1, a card-sort parad
igm involving similarity judgments demonstrated, for a sample of perso
ns 18 to 88 years old, that the prominence of affect in the mental rep
resentations of prospective social partners is positively associated w
ith age. In Study 2, the same experimental approach was applied to a s
ample of young gay men similar to one another in age, but notably diff
erent in their health status (that is, HIV negative; HIV positive, asy
mptomatic; and HIV positive, symptomatic). It was found that, with age
held constant, increasing closeness to the end of life is also associ
ated with an increasing prominence of affect in the mental representat
ions of social partners. The results suggest that the perception of Li
mited time, rather than chronological age, is the critical variable in
fluencing mental representations of social partners.
