One developmental task faced by children is to identify, remember, and learn from epistemic and moral agents around them who are known to be good or virtuous. Here, in 2 studies, we examined U.S children's (N = 138; 55% female, 45% male; predominantly White, middle-class) memory processes for agents varying in moral and epistemic virtue. In Study…

Children are known to accept communicated information, even when it contradicts their own judgments. Here, we explored the role of direct address and accuracy in children's testimonial decisions and socio-moral evaluations of the speaker. After 4-year-old children (N = 100) gave baseline classification responses for four hybrid animals, an adult…

What does it take know a moral truth or principle? Although testimony is an undisputed source of empirical knowledge of contingent facts, it is less clear whether it is possible to acquire "second-hand moral knowledge" (Jones, 1999; Wolff, 1998). In the present studies, 3- to 5-year-old Chinese (N = 124) and U.S. American (N = 90)…

Testimony is a valuable source of information for young learners, in particular if children maintain vigilance against errors while still being open to learning from imperfectly knowledgeable sources. We find support for this idea by examining how children evaluate individual speakers who present very different epistemic risks by being previously…

The reported research tested the hypothesis that young children detect logical inconsistency in communicative contexts that support the evaluation of speakers' epistemic reliability. In two experiments (N = 194), 3- to 5-year-olds were presented with two speakers who expressed logically consistent or inconsistent claims. Three-year-olds failed to…

Does valence play a role in children's sensitivity to and use of moral information in the service of selective learning? In the present experiment, we explored this question by presenting 3- to 5-year-old children with informants who behaved in ways consistent or inconsistent with sociomoral norms, such as helping a peer retrieve a toy or…

Children's sensitivity to the quality of epistemic reasons and their selective trust in the more reasonable of 2 informants was investigated in 2 experiments. Three-, 4-, and 5-year-old children (N = 90) were presented with speakers who stated different kinds of evidence for what they believed. Experiment 1 showed that children of all age groups…

Three studies examined 24-month-olds' sensitivity to the prior accuracy of the source of information and the way in which young children modify their word learning from inaccurate sources. In Experiments 1A, 2, and 3, toddlers interacted with an accurate or inaccurate speaker who trained and tested children's comprehension of a new word-object…

Many adult beliefs are based on the testimony provided by other people rather than on firsthand observation. Children also learn from other people's testimony. For example, they learn that mental processes depend on the brain, that the earth is spherical, and that hidden bodily organs constrain life and death. Such learning might indicate that…

Being able to evaluate the accuracy of an informant is essential to communication. Three experiments explored preschoolers' (N=119) understanding that, in cases of conflict, information from reliable informants is preferable to information from unreliable informants. In Experiment 1, children were presented with previously accurate and inaccurate…
