Lie-telling for personal gain in children with and without externalizing behavior problems

Lying behavior in adolescents with conduct disorder: An experimental study of the role of executive functioning

Children with conduct disorder (CD) are often reported to engage in higher rates of lying compared to their typically developing (TD) peers. However, there is a paucity of experimental evidence exploring the specific characteristics and underlying mechanisms driving the propensity for lying in this population. To address these gaps, this study aimed to investigate the relationship between executive functioning (EF) and lying behavior in adolescents with CD compared to TD adolescents. To assess spontaneous lying for personal gain, we used a spot-the-differences task with adolescents aged 13 to 16 (N = 115). EF abilities-including cognitive flexibility, inhibitory control, and working memory-were measured using the Trail Making Test, Color-Word Stroop Task, and Digit Span Test, respectively. We hypothesized that CD adolescents would lie more frequently for personal gain than TD adolescents. Additionally, we expected EF to negatively correlate with lying frequency in TD adolescents but positively correlate with lying frequency in CD adolescents. The results partially supported these hypotheses. While adolescents with CD did not lie significantly more often than TD adolescents, EF was differently related to lying frequency. Specifically, cognitive flexibility was positively associated with lying frequency in CD adolescents but was not significantly related to lying frequency in TD adolescents. Additionally, better inhibitory control was associated with less frequent lying across both groups. These findings provide new insights into the role of EF in adolescent dishonesty and suggest that EF may influence lying behavior differently in CD and TD populations.

Pants on fire: Risks for and outcomes of atypical lying

INTRODUCTION

Most people are generally honest, but around 5% of individuals are prolific liars, some of whom lie for fun or no reason. However, developmental research on atypical lying features (e.g., motives, attitudes, inclinations for dishonesty) and the associated traits and negative outcomes is lacking. We examined how psychopathic traits are related to the development of lying trajectories and whether exhibiting atypical lying features during a developmental period when lies tend to decrease in frequency (i.e., adolescence to adulthood) increases the risk for adulthood antisocial behaviors.

METHODS

Data come from the multisite Pathways to Desistance project, a longitudinal study of serious juvenile offenders in the United States who were interviewed across 11 time points over 7 years from 2000 to 2010. Age-based trajectory analyses modeled self-reported atypical lying features from ages 14 to 26 for male participants (N = 1170; 42.1% Black, 34.0% Hispanic, 19.2% White, 4.6% Other), and examined how subscales from the Youth Psychopathy Inventory predicted lying trajectory classes and whether those classes differed in adulthood offending and substance use.

RESULTS

Around 5% of the sample maintained elevated atypical lying features in adolescence and into adulthood. These individuals were more manipulative, remorseless, impulsive, and irresponsible in adolescence, and were more likely to offend and use substances in adulthood.

CONCLUSIONS

Findings highlight how atypical lying features during the normative developmental desistance period of lying may be elevated for prolific liars and how traits can be used to identify at-risk individuals. This information will help to inform intervention and prevention programs targeting externalizing behaviors.

Is childhood lying shaped by callous-unemotional traits or does lie-telling make children more callous-unemotional? A longitudinal between- and within-person perspective

The current study aims to advance knowledge on the causal interrelationship between childhood CU traits and lying both at a between- and a within-person perspective across a significant developmental period of mid-childhood to mid-adolescence. Cross-lagged panel models and Random-intercept cross-lagged panel models were used to investigate the prospective associations between lying and the distinct subcomponents of CU traits, including Callousness, Uncaring, and Unemotional in a sample of 719 children (T1; Mage = 10.73 years, SDage = 1.38, range = 7-15 years, 54.4% girls) across four assessment points. Results supported large vulnerability effects at the between-person level across time, indicating that CU traits predominantly influence the subsequent development of lying, with Callousness and Uncaring showing most profound effects on subsequent developmental processes of lying. At the within-person level, fluctuations in CU traits and lying were overall meaningfully related, but no causal relationship could be empirically determined. These findings provide a differentiated etiological viewpoint on the intertwinement of CU traits and lying at a young age, and underscore the importance of an early identification of children with callous and uncaring tendencies in order to prevent more persistent lying in adolescence.

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.

A cross-cultural comparison of the relation between children's moral standards of honesty and their lie-telling behavior

This study examined the relation between children's moral standards of honesty and their lie-telling behavior and the role that culture plays in this relation. In the study, 6- to 12-year-old Chinese and Northern American (Canadian and American) children underwent a behavioral paradigm where they had the opportunity to tell a lie about their performance to gain a benefit. The children then read vignettes where a character told lies to conceal a transgression committed to satisfy either a need or a desire and evaluated those lies. Northern American children were less likely to lie with age, but Chinese children did not demonstrate this trend. Lie-telling rates were higher for Chinese children than for Northern American children, but children were overall unlikely to tell a lie about their performance. Chinese children evaluated the lies in the vignettes more negatively than Northern American children. Children's moral standards of honesty were related to their lie-telling behavior, and the relation between children's moral standards and behavior did not differ by age in either culture. Overall, results suggest that culture influences how children make moral evaluations and decisions related to lie-telling and support the notion that children's moral standards and behavior are related. These findings suggest that socialization plays a central role in children's moral decision making related to honesty through helping children to develop moral standards related to honesty.
