Choosing to know: Children's decision to actively request social-norm information and their sharing behaviour.

We examined the sharing behaviour of children (aged 6-12) when presented with a generous vs. a selfish norm of sharing, or after having a choice of whether or not to request the (same) social-norm information. We found that with age children shared more overall and were more influenced by the generous norm in their recommendations to others. Moreover, the results show a significant effect of information-seeking on children's behaviour: children who were presented with the choice to request social-norm information and actively chose to request it were significantly more influenced by the information in their own sharing decisions and in their recommendation to others, compared with children who were presented with the same social-norm information without asking for it. The findings highlight the importance of an active search for information, rather than the information content per se, as a key factor in understanding the effect of social-norm information on children's sharing behaviour.
