Specifically, altruism (Essock-Vitale & McGuire, 1985; Leek & Smith, 1991; Smith, Kish, & Crawford, 1987) and willingness to act altruistically (Burnstein, Crandall, & Kitayama, 1994; Korchmaros, 1999; Ma, 1985a, 1985b, 1989, 1992; O’Neill & Petrinovich, 1998; Petrinovich, O’Neill, & Jorgensen, 1993) increase as genetic relatedness increases. However, it has not been established what proximal causes lead to this overall pattern of altruistic behavior. Even if humans are genetically predisposed to be attuned to markers of genetic relatedness, the specific nature of the psychological mechanisms that lead one to be more willing to act altruistically toward kin than nonkin and more willing to act altruistically toward close kin than more distant kin is still unknown. It is plausible that these psychological mechanisms are, in part, based on emotional closeness (Cunningham, 1986)—a sense of concern, trust, and caring for another individual and enjoyment of the relatio...
