3 September 2012Very young children are typically thought to be egocentric and to struggle with sharing with others, particularly when this means a potential loss to themselves. However, in a paper published in the journal PLoS ONE, Patricia Kanngiesser and Felix Warneken (Harvard University) have shown that, despite this egocentric bias, 3-year-olds do show a degree of fairness when sharing resources. In particular, they give a greater proportion of a sharable reward to a 3rd party who put more effort into a joint task than they give to a 3rd party who put less work into winning the reward with them.
