Belief revision in children: serial judgment in social cognition and decision-making domains.
Belief revision in 5- to 9-year-olds was studied with an information integration approach. In the social task, children judged niceness of story children, having heard about their good and bad deeds. In the decision task, of parallel structure, they judged what proportion of a group of turtles' catch of starfish was red or gold. In both tasks, 4-5 samples were presented successively, with children adjusting their judgment after each. All ages took sample composition into account, and judgments could be described by a serial integration model previously supported for adults. Recency effects were found as well and were stronger for younger children and in the social task. Further model analysis showed, however, that much of this recency was short-lived and that a stable opinion, to which early and later informers contributed more evenly, developed underneath. Overall, similar processes may underlie serial belief formation across the age range and across domains.
