The development of anonymous giving in relation to ownership understanding, theory of mind, empathy, and differences in relatedness

Prosocial behavior can be defined as any behavior that an individual engages in to
benefit another (Eisenberg, Fabes, & Spinrad, 2006). Prosociality is not one homogenous trait, however, but is made up of three specific types of behavior: helping, cooperating, and sharing (or, more accurately, donating) (Tomasello, 2009). Although helping and cooperating are important to understanding prosocial development, giving behaviors might be particularly informative when trying to understand prosociality in young children as it poses a distinct problem for younger children (Tomasello, 1998). Research on proximate causes of prosocial behavior state that these behaviors are influenced by emotions of empathy (Batson, 1991), theory of mind, or understanding of social norms of ownership (Blake & Rand, 2010). Research on more ultimate causes of prosociality suggest that these behaviors evolved due to mechanisms or kin selection (Hamilton, 1964) and inclusive fitness (Trivers, 1971), and is evident by the effect of social category and relatedness on donations in resource- allocation games (Gummerum et al., 2009). Research with children using resource- allocations games, such as the dictator game, are sparse, but typically find that children donate more as they get older, and that out-group receive fewer allocations than in-group members (Moore, 2009). This research also highlight the importance of anonymity and its effect on prosociality. When tested using an anonymous design, children donate less and some children don’t donate at all (Benenson et al., 2007).
Using an anonymous dictator game, children’s giving behaviors were examined
across in- group, out-group, and family members. Thirty-five children (12 3-year-olds (7
male), 13 4-year-olds (8 male), and 10 5-year-olds (7 male) completed the experiment.
Each child participated in each condition, as well as measures of theory of mind and
ownership understanding. Children’s empathy scores were attained from a parent questionnaire regarding children’s empathic behaviors. Results revealed that some children did not donate any stickers at all; seven in total, and that these children differed significantly from those that gave on measures of empathy. Of those that donated, 3-year-old children donated significantly more than 5-year-old children (F(1,3) =3.64, p < .05). This is contrary to previous findings which find that giving increases across age., The was no main effect for Recipient, and no significant interaction between Age and Recipient. Five-year-olds scored significantly higher on measures of ownership understanding (F(2, 25) = 4.36, p< .05), suggesting that understanding of social norms of ownership may be partially responsible for their decrease in overall giving.
