The honest truth about deception: Demographic, cognitive, and neural correlates of child repeated deceptive behavior

To tell the truth or not: What effortful control, false belief, and sympathy tell us about preschoolers' instrumental lies

This study aimed to examine the predictors of instrumental lies in preschool children, specifically focusing on false belief, effortful control, and sympathy. Instrumental lies are intentional falsehoods used to achieve personal goals such as avoiding punishment and obtaining an undeserved reward. A total of 192 preschool children (age range = 32-73 month-olds), along with their mothers and fathers, participated in the study. The Temptation Resistance Paradigm, an experimental task, was employed to elicit instrumental lies from the children. The children also completed first-order false belief measures, and their parents filled out questionnaires assessing their children's effortful control and sympathy skills. Results revealed a positive association between children's effortful control and their decisions to tell instrumental lies. However, no significant relationship was found between false belief and instrumental lying. Age moderated the link between sympathy and the decision to tell instrumental lies, with sympathy being negatively associated with lie-telling behavior among older children but showing no effect among younger children. The study variables did not predict the maintenance of instrumental lies. Overall, this study provides valuable insights into the role of effortful control and sympathy as underlying temperamental and emotional processes influencing children's decisions to engage in instrumental lie-telling.

When kindergarteners are tempted to deceive: A study of factors predicting lie-telling for personal gain

The current study examined the relations between children's cognitive and emotion abilities with their likelihood to tell a lie for personal gain in a tempting situation. These relations were examined using behavioral tasks and questionnaires. A total of 202 Israel Arab Muslim kindergarten children participated in this study. Our results showed that behavioral self-regulation was positively associated with children's likelihood to tell a lie for personal gain. Children with higher behavioral self-regulation actually tended to lie more for their own gain, suggesting that the likelihood to tell a lie might be related to children's ability to mobilize and integrate their cognitive abilities to self-regulate their behavior. In addition, through exploratory analysis, we found a positive relation between theory of mind and children's likelihood to tell a lie, which was moderated by inhibition. Specifically, only among children with low inhibition was there a positive correlation between their theory of mind and the likelihood to lie. Moreover, age and gender were related to children's lie-telling; older children tended more to lie for their own gain, and this likelihood was higher for boys than for girls.

Interpretive Diversity Understanding, Parental Practices, and Contextual Factors Involved in Primary School-age Children's Cheating and Lying Behavior

Dishonesty is an interpersonal process that relies on sophisticated socio-cognitive mechanisms embedded in a complex network of individual and contextual factors. The present study examined parental rearing practices, bilingualism, socioeconomic status, and children's interpretive diversity understanding (i.e., the ability to understand the constructive nature of the human mind) in relation to their cheating and lie-telling behavior. 196 school-age children (9-11 years old) participated in a novel trivia game-like temptation resistance paradigm to elicit dishonesty and to verify their interpretive diversity understanding. Results revealed that children's decision to cheat and lie was positively associated with their understanding of the constructive nature of the human mind and with parental rejection. Children with rejective parents were more likely to lie compared to their counterparts. This may suggest that understanding social interactions and the relationship with caregivers can impact children's cheating behavior and the extent to which they are willing to deceive about it. Understanding the constructive nature of the mind was also a positive predictor of children's ability to maintain their lies. Finally, being bilingual and having a higher socioeconomic status positively predicted children's deception, these intriguing results warranting further research into the complex network of deception influences.

The concept of lying, moral reasoning and children's willingness to lie at the request of an adult

This research aims to understand how children conceptualise lying and how they associate it with moral reasoning within a narrative that contains everyday moral transgressions. This study also explores whether children are willing to lie when they are asked to do so by close adults, such as mothers, fathers and teachers, even after declaring that lying is wrong. We interviewed children (N = 146) from first to fourth grade on these themes, and discovered a developmental trend in the concept of lying, which is associated with other moral reasoning dimensions. Most children could define lying in a reasonable and accurate manner, and considered it inappropriate behaviour, but half admitted to lying after a close adult requested it.

The Role of Reward System in Dishonest Behavior: A Functional Near-Infrared Spectroscopy Study

Previous studies showed that the cortical reward system plays an important role in deceptive behavior. However, how the reward system activates during the whole course of dishonest behavior and how it affects dishonest decisions remain unclear. The current study investigated these questions. One hundred and two participants were included in the final analysis. They completed two tasks: monetary incentive delay (MID) task and an honesty task. The MID task served as the localizer task and the honesty task was used to measure participants' deceptive behaviors. Participants' spontaneous responses in the honesty task were categorized into three conditions: Correct-Truth condition (tell the truth after guessing correctly), Incorrect-Truth condition (tell the truth after guessing incorrectly), and Incorrect-Lie condition (tell lies after guessing incorrectly). To reduce contamination from neighboring functional regions as well as to increase sensitivity to small effects (Powell et al., Devel Sci 21:e12595, 2018), we adopted the individual functional channel of interest (fCOI) approach to analyze the data. Specially, we identified the channels of interest in the MID task in individual participants and then applied them to the honesty task. The result suggested that the reward system showed different activation patterns during different phases: In the pre-decision phase, the reward system was activated with the winning of the reward. During the decision and feedback phase, the reward system was activated when people made the decisions to be dishonest and when they evaluated the outcome of their decisions. Furthermore, the result showed that neural activity of the reward system toward the outcome of their decision was related to subsequent dishonest behaviors. Thus, the present study confirmed the important role of the reward system in deception. These results can also shed light on how one could use neuroimaging techniques to perform lie-detection.
