Advanced theory of mind and children's prosocial lie-telling in middle childhood: A training study.

Children's advanced theory of mind (AToM) is concurrently associated with their prosocial lie-telling. However, the causal link between AToM and prosocial lie-telling has not yet been demonstrated. To address this gap, the current study adopted a training paradigm and investigated the role of AToM in children's prosocial lie-telling in middle childhood. A total of 66 9- and 10-year-old children who did not demonstrate any prosocial lie-telling in a disappointment gift paradigm at the baseline were recruited and randomly assigned to either the experimental group (n = 32) or an active control group (n = 34). The experimental group underwent a conversation-based training program of four sessions. The results showed significantly greater gains in AToM at the posttest for the experimental group children compared with the control group children, controlling for family socioeconomic status, children's literacy score, working memory, and inhibition. More important, the experimental group children were more likely to tell prosocial lies than the control group, even after controlling for the pretest AToM and other covariates. However, the training effects faded at the 6-month follow-up test after the training's completion. These findings provide the first evidence for the causal role of AToM in the development of prosocial lie-telling in middle childhood. The fade-out effect is discussed in the context of educational interventions.

Prosocial lie-telling in preschoolers: The impacts of ethnic background, parental factors, and perceived consequence for the partner.

This study explored prosocial lie-telling behavior in 4- to 5-year-old children from two ethnic groups: European Canadian (n = 49; excluding Eastern European Canadian) and Chinese Canadian (n = 45). Children completed an online experiment involving two real-life politeness situations. In the first situation, children were asked whether they thought someone with a red mark on their face looked okay for a photo or a Zoom party (Reverse Rouge Task). In the second situation, upon hearing the researcher's misconception about two pieces of artwork, children were asked whether they agreed with the researcher (Art Rating Task). Parents completed questionnaires that measured their levels of collectivist orientation and parenting styles. Contrary to our hypotheses, the likelihood of children telling a prosocial lie did not vary as a function of their ethnic group or the presence of a perceived consequence for the partner, nor was it predicated by parental collectivist orientation. Interestingly, prosocial liars were more likely to have authoritative parents, whereas blunt-truth tellers were more likely to have permissive parents. These findings have important implications for the ways in which certain parenting styles influence the socialization of positive politeness in children. In addition, the similar rates of prosocial lying across the two ethnic groups suggest that children who are born and raised in Canada may be much more alike than different in their prosocial lie-telling behavior, despite coming from different ethnic backgrounds.

Perceptions of Dishonesty: Understanding Parents' Reports of and Influence on Children and Adolescents' Lie-Telling.

Previous studies suggest parents lack knowledge regarding child and adolescent lie-telling; however, no study to date has examined children's and parents' reports of lying within parent-child dyads. The current study examined parents' knowledge of and influence on children's and adolescents' lie-telling. Parent-child dyads (N= 351) completed self-report surveys. Children (8-14 years, 52.3% children female) reported on prosocial and antisocial lie-telling. Parents (Mage = 41.68, 89.5% parents female) reported on their child's lie-telling, as well as their own honesty-targeted parenting strategies and modeling of dishonest behaviors. Parents' reports were unrelated to children's and adolescents' reports of prosocial and antisocial lie-telling. Additionally, parents' honesty-targeted parenting strategies and modeling of dishonesty did not predict children's lie-telling. Parents' behaviors predicted their reports of children's lie-telling, suggesting parents' behaviors bias their reports. Parents' biased perception of adolescents lie-telling may have negative implications for parent-child relationships.
