The relation between age and helping was examined in an experimental study in which children directly observed an emergency and had the opportunity to intervene. A second study was then conducted, in which an emergency was clearly staged, in order to elicit comments about factors that may inhibit helping. Results of Study 1 were consistent with earlier findings of a curvilinear relationship between age and helping among children and early adolescents, with fourth and tenth graders helping significantly more than first and seventh graders. Significantly more help was given to a toddler than to an age peer and to a person whose injury appeared serious enough so that he or she could not get up unaided. Results obtained from Study 2 suggested that helping by younger children was inhibited by fear of possible inadequacy, and helping by adolescents was inhibited by fear of disapproval and/or sensitivity to the possible embarrassment felt by potential recipients. Reticence was expressed least where the potential recipient was a toddler.Children express concern for others beginning at a very early age (Rheingold, Hay, & West, 1976;Strayer, Wareing, & Rushton, 1979;Waxier, Yarrow, & King, 1979). Furthermore, as the child grows older, there are likely to be concomitant increases in altruistic moral judgment (Eisenberg, 1982;Bar-Tal, Raviv, & Shavit, 1981), in the ability to empathize with others (Hoffman, 1975), in the value placed on altruistic behavior (Rushton, 1976), and in both perceived and actual competence (Midlarsky, 1984; Peterson, 1983a, b). All of these, in turn, are apparently related to altruism-denned here as self-sacrifice motivated by the desire to help another (Bryan & London, 1970;Midlarsky, 1984).The prediction that altruism should increase with age has primarily been investigated in regard to two types of behavior-We thank Susan Midlarsky, whose intuition about factors impeding interpersonal helping motivated this investigation, as well as Shirley Christian and Sarah Cilano, for their help during the study.
