Children's and Adolescents' Decisions about Sharing Money with Others

Two hundred and ninety-four participants aged between 7 and 17 years of age were asked to share out money between themselves and another, imaginary group. Individual responses were recorded as well as responses after discussion in a group with two other participants. The distribution task took place in two different experimental conditions that either gave participants a free choice about how much to offer to the other group or involved making a strategic offer to avoid the other group rejecting an offer and losing all the money. From 10 years of age onwards, when allowed to choose freely how much to share, boys made progressively less generous offers than girls whereas girls' offers remained the same with age. However, when inter-group strategic constraints were present, there were few gender differences from 10 years of age. The order in which games were presented was a powerful influence on the offers that participants made.
