When navigating unfamiliar social environments, it is important to identify who is powerful. Determining who has power can be challenging because observers may have limited social information, and because people achieve influence for many reasons. In experiments with 3-to 5-year-old children (n = 192) and adults (n = 32), we investigated the developmental origins and conceptual structure of power judgments based on physical appearance. At 3 years of age, children already associated physical strength with expansive posture; soon after, expansive postures also supported judgments of normative authority and were joined by similar judgments about masculine facial structure. By the age of 4, children also matched high-and low-power versions of faces and postures together, indicating that they draw connections between different aspects of more or less powerful appearance. The complexity and timing of these changes highlights limitations in current accounts of the origins of adults' intuitions about powerful appearances. This study documents several novel developmental patterns that generate new hypotheses about the mechanisms that support the emergence of children's intuitions.

This preprint may differ from the final copy-edited version. Highlights• From 4 years, children view an unhelpful person as an authority figure.• From 6 years, they predict subordinates, not authorities, will help third parties.• But they do not view helping or being helped as diagnostic about authority.• Once children hold consistent views, these match adults' intuitions.• Overall, people more easily associate authority with indifference to others' needs.

This study examined social influences on 3-year-old children's decisions to help an experimenter gain another person's attention (N = 32). Children were slower to help the experimenter when the target had previously expressed disinterest in attending to her. Shy children were less likely to support the experimenter's attempts to communicate with the target; however, this association was not influenced by children's knowledge of the target's disinterest, and there was no relation between shyness and children's support for a separate physical goal. Therefore, young children's decisions to act helpfully incorporate consideration for others beyond a focal person with an unmet need, and they are further constrained by children's own comfort with the actions required to help.
