What do children do when they do not want to obey but cannot afford to disobey? Might they, like adults, feign misunderstanding and seek out loopholes? Across four studies (N = 723; 44% female; USA; majority White; data collected 2020-2023), we find that loophole behavior emerges around ages 5 to 6 (Study 1, 3-18 years), that children think…

The present study compared the lie-telling behavior of 3- and 4-year-old West African children (N = 84) from either a punitive or a nonpunitive school. Children were told not to peek at a toy when left alone in a room. Most children could not resist the temptation and peeked at the toy. When the experimenter asked them if they had peeked, the…

This study examined how informants' traits affect how children seek information, trust testimony, and make inferences about informants' knowledge. Eighty-one 3- to 6-year-olds and 26 adults completed tasks where they requested and endorsed information provided by one of two informants with conflicting traits (e.g., honesty vs. dishonesty).…

This study investigated differences in children's and adolescents' experiences of harming their siblings and friends. Participants ("N" = 101; 7-, 11-, and 16-year-olds) provided accounts of events when they hurt a younger sibling and a friend. Harm against friends was described as unusual, unforeseeable, and circumstantial. By contrast,…

Preschool-age children's reasoning about the reliability of deceptive sources was investigated. Ninety 3- to 5-year-olds watched several trials in which an informant gave advice about the location of a hidden sticker. Informants were either "helpers" who were happy to give correct advice, or "trickers" who were happy to give incorrect advice.…

In this study, the prevailing view that girls are pervasively more skilled in their friendships than boys was challenged by examining whether girls respond more negatively than boys when a friend violates core friendship expectations. Fourth- and fifth-grade children (n = 267) responded to vignettes depicting transgressions involving a friend's…

The relation between children's lie-telling and their social and cognitive development was examined. Children (3-8 years) were told not to peek at a toy. Most children peeked and later lied about peeking. Children's subsequent verbal statements were not always consistent with their initial denial and leaked critical information revealing their…

Asserts that theory of mind is unique to humans and that its original function was to provide a more abstract level of describing ancient behavioral patterns, such as deception, reconciliation, and gaze following. Suggests that initial selective advantage of theory of mind may have been increased flexibility of already-existing behaviors, not…

This research examined adolescents' judgments about lying to circumvent directives from parents or friends in the moral, personal, and prudential domains. One hundred and twenty-eight adolescents (12.1-17.3 years) were presented with situations in which an adolescent avoids a directive through deception. The majority of adolescents judged some…

Used stories involving self-deception, lying, and misleading appearances to examine 4- to 9-year olds' understanding of the relations between false belief, evidence, and epistemic responsibility. Found that younger children who understood false belief understood simpler types of deception but that understanding self-deceivers' epistemic…

Three-year olds participated in a deceptive action as part of another person's false-belief test. Found that children who had strategically planned a deception were better at answering questions about another's false beliefs than children who had merely watched the deceptive action. This effect was not found when children performed the same action…

Three studies examined whether preschoolers' difficulties with deception and false belief arise from lack of inhibitory control rather than conceptual deficit. Found that 3-year olds deceived frequently under conditions requiring relatively low inhibitory control, but not high inhibitory control. Findings were not due to social intimidation, and…

Investigated the ability of 56 children of 2-4 years to deceptively lead others into false beliefs. Results show that 2 1/2-year-olds already practice a variety of deceptive strategies that presuppose an operative theory of mind. (RJC)

To determine whether children younger than four have an authentic theory of mind, studies relying on deceptive hiding measures for indexing false belief were carried out. Children accurately anticipated the impact of deceptive strategies on the behavior and belief of opponents and used information management to help and hinder others' efforts. (BC)

Children's use of the terms "lie" and "truth" was examined. Participants were 150 subjects in five groups: nursery schoolers, preschoolers, first graders, fifth graders, and adults. Results support the development of definitional prototypes for the concepts of lie and truth. (RH)
