The effect of hunger on children's sharing behavior and fairness preferences

How does feeling hungry affect children's sharing and evaluations of others' moral decision making? To examine this question, we gave 4- to 9-year-old children the opportunity to share resources with an anonymous other child and to evaluate third-party resource allocation decisions between hungry and full recipients. We also measured children's subjective reports of their own hunger, predicting that hungry children would be less generous in their own sharing and more likely to prefer distributions that favor the hungry recipient. Children's sharing increased with age, as did positive evaluations of equitable third-party distributions. Hungrier children were less likely to share overall, but particularly when sharing food-relevant resources. Hunger did not influence third-party resource allocation evaluations, and children still expected fairness from others even when behaving differently themselves. (C) 2019 Elsevier Inc.
