Development of lying to conceal a transgression: Children's control of expressive behaviour during verbal deception

The present study examined lying behaviour in children between 3 and 7 years of age with two experiments. A temptation resistance paradigm was used in which children were left alone in a room with a music-playing toy placed behind their back. The children were told not to peek at the toy. Most children could not resist the temptation and peeked at the toy. When the experimenter asked them whether they had peeked, about half of the 3-year-olds confessed to their transgression, whereas most older children lied. Näve adult evaluators (undergraduate students and parents) who watched video clips of the children’s responses could not discriminate lie-tellers from nonliars on the basis of their nonverbal expressive behaviours. However, the children were poor at semantic leakage control and adults could correctly identify most of the lie-tellers based on their verbal statements made in the same context as the lie. The combined results regarding children’s verbal and nonverbal leakage control suggest that children under 8 years of age are not fully skilled lie-tellers.

Social and Cognitive Correlates of Children’s Lying Behavior

The relation between childrens 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. Childrens subsequent verbal statements were not always consistent with their initial denial and leaked critical information revealing their deceit. Childrens conceptual moral understanding of lies, executive functioning, and theory-of-mind understanding were also assessed. Childrens initial false denials were related to their first-order belief understanding and their inhibitory control. Childrens ability to maintain their lies was related to their second-order belief understanding. Childrens lying was related to their moral evaluations. These findings suggest that social and cognitive factors may play an important role in childrens lie-telling abilities.

Lying in the Elementary School Years: Verbal Deception and Its Relation to Second-Order Belief Understanding

The development of lying to conceal ones own transgression was examined in school-age children. Children (N=172) between 6 and 11 years of age were asked not to peek at the answer to a trivia question while left alone in a room. Half of the children could not resist temptation and peeked at the answer. When the experimenter asked them whether they had peeked, the majority of children lied. However, childrens subsequent verbal statements, made in response to follow-up questioning, were not always consistent with their initial denial and, hence, leaked critical information to reveal their deceit. Childrens ability to maintain consistency between their initial lie and subsequent verbal statements increased with age. This ability is also positively correlated with childrens 2nd-order belief scores, suggesting that theory of mind understanding plays an important role in childrens ability to lie consistently.

Children's Conceptual Knowledge of Lying and its Relation to Their Actual Behaviors: Implications for Court Competence Examinations

Child witnesses must undergo a competence examination in which they must show appropriate conceptual understanding of lying and truth-telling, and promise to tell the truth. Three experiments (Ns = 123, 103, 177) were conducted to address the assumptions underlying the court competence examination that (1) children who understand lying and its moral implications are less likely to lie and (2) discussing the conceptual issues concerning lying and having children promising to tell the truth promotes truth-telling. Both measures of lying and understanding of truth- and lie-telling were obtained from children between 3 and 7 years of age. Most children demonstrated appropriate conceptual knowledge of lying and truth-telling and the obligation to tell the truth, but many of the same children lied to conceal their own transgression. Promising to tell the truth significantly reduced lying. Implications for legal systems are discussed.

White lie-telling in children for politeness purposes.

Prosocial lie-telling behavior in children between 3 and 11 years of age was examined using an undesirable gift paradigm. In the first condition, children received an undesirable gift and were questioned by the gift-giver about whether they liked the gift. In the second condition, children were also given an undesirable gift but received parental encouragement to tell a white lie prior to being questioned by the gift-giver. In the third condition, the childs parent received an undesirable gift and the child was encouraged to lie on behalf of their parent. In all conditions, the majority of children told a white lie and this tendency increased with age. Coding of childrens facial expressions using Ekman and Friesens (1978) Facial Action Coding System revealed significant but small differences between lie-tellers and control children in terms of both positive and negative facial expressions. Detailed parental instruction facilitated childrens display of appropriate verbal and nonverbal expressive behaviors when they received an undesirable gift.

From little white lies to filthy liars: the evolution of honesty and deception in young children.

Though it is frequently condemned, lie-telling is a common and frequent activity in interpersonal interactions, with apparent social risks and benefits. The current review examines the development of deception among children. It is argued that early lying is normative, reflecting childrens emerging cognitive and social development. Children lie to preserve self-interests as well as for the benefit of others. With age, children learn about the social norms that promote honesty while encouraging occasional prosocial lie-telling. Yet, lying can become a problem behavior with frequent or inappropriate use over time. Chronic lie-telling of any sort risks social consequences, such as the loss of credibility and damage to relationships. By middle childhood, chronic reliance on lying may be related to poor development of conscience, weak self-regulatory control, and antisocial behavior, and it could be indicative of maladjustment and put the individual in conflict with the environment. The goal of the current chapter is to capture the complexity of lying and build a preliminary understanding of how childrens social experiences with their environments, their own dispositions, and their developing cognitive maturity interact, over time, to predict their lying behavior and, for some, their chronic and problem lying. Implications for fostering honesty in young children are discussed.

A Punitive Environment Fosters Children's Dishonesty: A Natural Experiment

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 majority of the punitive school peekers lied about peeking at the toy while significantly fewer nonpunitive school children did so. The punitive school children were better able to maintain their deception than nonpunitive school children when answering follow-up questions. Thus, a punitive environment not only fosters increased dishonesty but also childrens abilities to lie to conceal their transgressions.

Can Classic Moral Stories Promote Honesty in Children

The classic moral stories have been used extensively to teach children about the consequences of lying and the virtue of honesty. Despite their widespread use, there is no evidence whether these stories actually promote honesty in children. This study compared the effectiveness of four classic moral stories in promoting honesty in 3- to 7-year-olds. Surprisingly, the stories of “Pinocchio” and “The Boy Who Cried Wolf” failed to reduce lying in children. In contrast, the apocryphal story of “George Washington and the Cherry Tree” significantly increased truth telling. Further results suggest that the reason for the difference in honesty-promoting effectiveness between the “George Washington” story and the other stories was that the former emphasizes the positive consequences of honesty, whereas the latter focus on the negative consequences of dishonesty. When the “George Washington” story was altered to focus on the negative consequences of dishonesty, it too failed to promote honesty in children.

The Reliability of Lie Detection Performance

We examined whether individuals’ ability to detect deception remained stable over time. In two sessions, held one week apart, university students viewed video clips of individuals and attempted to differentiate between the lie-tellers and truth-tellers. Overall, participants had difficulty detecting all types of deception. When viewing children answering yes–no questions about a transgression (Experiments 1 and 5), participants’ performance was highly reliable. However, rating adults who provided truthful or fabricated accounts did not produce a significant alternate forms correlation (Experiment 2). This lack of reliability was not due to the types of deceivers (i.e., children versus adults) or interviews (i.e., closed-ended questions versus extended accounts) (Experiment 3). Finally, the type of deceptive scenario (naturalistic vs. experimentally-manipulated) could not account for differences in reliability (Experiment 4). Theoretical and legal implications are discussed.

The role of executive functions and theory of mind in children's prosocial lie-telling.

Childrens prosocial lying was examined in relation to executive functioning skills and theory of mind development. Prosocial lying was observed using a disappointing gift paradigm. Of the 79 children (ages 6-12 years) who completed the disappointing gift paradigm, 47 (59.5%) told a prosocial lie to a research assistant about liking their prize. In addition, of those children who told prosocial lies, 25 (53.2%) maintained semantic leakage control during follow-up questioning, thereby demonstrating advanced lie-telling skills. When executive functioning was examined, children who told prosocial lies were found to have significantly higher performance on measures of working memory and inhibitory control. In addition, children who lied and maintained semantic leakage control also displayed more advanced theory of mind understanding. Although childrens age was not a predictor of lie-telling behavior (i.e., truthful vs. lie-teller), age was a significant predictor of semantic leakage control, with older children being more likely to maintain their lies during follow-up questioning.
