Children often say that possible events are impossible, and only gradually come to see these events as possible. For instance, they often deny that people could do unusual things, like own a pet peacock, or immoral things, like stealing or lying. These possibility denials are surprising. For instance, children have first-hand experience with the…

Many previous studies indicate that children are highly sensitive to the immoral behavior of others, preferring prosocial over antisocial characters. Accordingly, children avoid transgressors from a very early age. A special kind of transgressor is the moral hypocrite, who not only acts immorally but also acts in contrast to what they preach.…

nChildren's moral judgments of resource distributions as having "fair" or "unfair" origins play an important role in early social cognition. What factors shape these judgments? The present study advances research on this question in two primary ways: First, while prior work has typically assigned children to an advantaged or…

Middle childhood seems to be crucial for the emergence of a moral identity, that is, an evaluative stance of how important it is for someone's sense of self to be moral. This study investigates the effects of moral identity on the neural processing of moral content in 10-year-old children. Participants were presented with scenes portraying…

Recent work has documented that despite preschool-aged children's understanding of social norms surrounding sharing, they fail to share their resources equally in many contexts. Here we explored two hypotheses for this failure: an "insufficient motivation hypothesis" and an "insufficient cognitive resources hypothesis." With…

In three experiments involving 207 preschoolers and 28 adults, we investigated the extent to which young children base moral judgments of actions aimed to protect others on utilitarian principles. When asked to judge the rightness of intervening to hurt one person in order to save five others, the large majority of children aged 3 to 5 years…

Three experiments investigated whether children in grades K, 2, and 4 (n = 144) view emotional comprehension as important in solving moral dilemmas. The experiments asked whether a human or an artificially intelligent machine would be best at solving different types of problems, ranging from moral and emotional to nonmoral and pragmatic. In…
