What makes the windows task difficult for young children: Rule inference or rule use?

Abstract

The windows task is difficult for young children. In this task, a child is shown two boxes with windows revealing that one is empty, whereas the other contains a treat. The child is asked to point to a box for an opponent to look in. The child then “wins” the contents of the other box (the treat). To pass the task, the child must use a rule such as “point to the empty box.” But crucially, because the child is not told this rule by the experimenter, he or she must first infer it. Therefore, the windows task has two distinct requirements: (a) infer the rule “point to the empty box” and, once the rule is inferred, (b) use the rule by holding it in mind while inhibiting the prepotent response of pointing to the treat. In this study, the authors sought to determine which of these two requirements was responsible for poor performance on the windows task. They compared the performance of 3 1 2 -year-olds ( N=40) on four tasks: the standard windows task, a version of the windows task that required rule use but not rule inference, and two versions of the day–night task that also required rule use but not rule inference. The relative performance on these four tasks and the pattern of correlations among them suggested that children had difficulty in inferring a rule that enables them to pass the task, whereas they had little difficulty in using the rule. Little evidence was obtained to suggest that the standard windows task requires inhibition.
