This study examined dispositional and situational correlates of donating behavior in a sample of 221 eight-year-old children. Children were shown a promotional clip for a charity, including a donation call. For a random half of the children, the video fragment ended with a probe of a same-sex peer donating money to the charity. Seeing a peer donate was associated with higher donations. Empathy and inhibition were not related to donating. Anxiety and social responsiveness moderated the effect of the situational manipulation on donating. Anxious children and children with less social responsiveness problems donated more after seeing the donating peer than did less anxious children and children with more social responsiveness problems. Moreover, in absence of the donating peer, anxious children donated less money than did less anxious children. Our results indicate that donating behavior is dependent on situational demands, and the situational effect differs depending on children's levels of anxiety or social responsiveness.
