ABSTRACT

The present study examined children's lies to help others obtain benefits (other-benefiting lying) and its relation to theory of mind (ToM) and empathy among 3-5-year-old preschool children. One hundred nine children were recruited from preschools in China. A modified hide-and-seek paradigm was used to measure children's other-benefiting lying behavior, a ToM scale was used to measure children's ToM abilities, and an empathy scale was used to measure children's empathy abilities. Results showed that children tended to tell more lies to help other to get benefits as age increased, and further analyses showed that this other-benefiting lying was related to children's ToM component of false belief understanding and their cognitive empathy performance. These findings provide evidence that cognitive factors play important roles in children's lying to help others.

ABSTRACT

A number of psychological theories propose that deception involves more cognitive control than truth-telling. Over the last decades, event-related potentials (ERPs) have been used to unravel this question, but the findings are mixed. To address this controversy, two meta-analyses were conducted to quantify the results of existing studies reporting N2 or medial frontal negativity (MFN) associated with deception. In total, 32 papers consisting of 1091 participants were included, which yielded 32 effect sizes for N2 and 7 effect sizes for MFN. We found that deception was associated with a more negative N2 and MFN than truth-telling with medium and large effect sizes (r = .25 and .51, respectively). We also found that the deception paradigm modulated the results (p = .043), but found no evidence for publication bias. Our findings indicate that deception involves more cognitive control than truth-telling. Our review also identifies gaps in this literature, including a need for more ERP studies using spontaneous deception.

ABSTRACT

Children's lying is a major concern for parents and teachers alike, not only because lying is an antisocial behavior but also because children's lying correlates with other behavior problems, such as aggression and delinquency. Despite considerable correlational evidence demonstrating the relation between children's lying and behavior problems, experimental evidence is scarce. This study uses a novel task to experimentally examine the relation between lying for personal reward and behavior problem symptoms among 9- to 11-year-old typically developed children (N = 275, 139 boys). Results revealed a positive correlation between children's lying for personal reward and their behavior problem symptoms, and this correlation increases with age. Overall, this study provides experimental evidence suggesting children's lying for personal reward is associated with behavior problems.

ABSTRACT

The feedback concealed information test (fCIT) is a new variant of the CIT that added feedback about participants' concealing performances in the classical CIT. The advantage of the fCIT is that the resulting feedback related event-related potentials (ERPs) can be used to detect concealed information. However, the detection efficiency of feedback-based ERPs varies across studies. The present experiment examined whether the extent participants believed the feedback influenced their detection efficiency. Specifically, participants did a mock crime and were then tested in a fCIT. Following the fCIT, participants were asked to report how much they believed the feedback was accurate. Results showed that there were no significant correlations between the amplitude of the feedback related negativity (FRN), feedback P300, and participants' self-report at the group level. However, individual analyses showed that the detection efficiency of both the FRN and feedback P300 were influenced by participants' belief about the presented feedback. The detection efficiency of the FRN and the feedback P300 was higher among participants who believed the feedback. These findings suggest that the fCIT is dependent to some extent on the participants' level of belief in the feedback.

ABSTRACT

This research examined the effectiveness of using norms to promote honesty. Participants were Han Chinese children (N = 568, 50.4% male, 3.24 to 6.00 years, collected 2020-2022). Relative to children in a control condition, children in Study 1 were more likely to confess to having cheated in a game after being presented with a descriptive norm indicating that confessions are typical, or an injunctive norm indicating that most other children approve of confessing. Study 2 showed that this finding was not due to a methodological artifact, and Study 3 replicated the effect in a context in which the norm information was conveyed by someone other than the experimenter. The findings suggest that messages about social norms can influence children's honesty.

ABSTRACT

People are sometimes tempted to lie for their own benefit if it would not harm others. For adults, dishonesty is the default response in these circumstances. The developmental origins of this phenomenon were investigated between 2019 and 2021 among 6- to 11-year-old Han Chinese children from China (N = 548, 49% female). Children had an opportunity to win prizes in a behavioral economics game (Experiment 1) or a temptation resistance game adapted from developmental psychology (Experiment 2). In each experiment, the youngest children showed a default tendency of honesty and there was an overall age-related shift toward a default tendency of dishonesty. These findings provide direct evidence of developmental change in the automatic and controlled processes that underlie moral behavior.

ABSTRACT

The feedback concealed information test (fCIT) is a novel form of the CIT, providing participants with feedback regarding their memory concealment performance. The fCIT utilizes event-related potentials (recognition-P300 and feedback-related event-related potentials) and has been shown to provide high efficiency in detecting information concealment. However, it is unclear how well the fCIT performs in the presence of mental countermeasures. To address this question, participants were trained to use countermeasures during fCIT. Results showed that the recognition-P300 efficiency decreased when participants used countermeasures. However, the efficiencies of feedback-related negativity and feedback-P300 were unchanged, with feedback-P300 still showing a high detection efficiency (AUC = 0.86) during countermeasures. These findings demonstrate the potential of fCIT for subverting countermeasures.

ABSTRACT

In this study, brain imaging data from functional near-infrared spectroscopy (fNIRS) associated with skin conductance response (SCR), heart rate (HR), and reaction time (RT) were combined to determine if the combination of these indicators could improve the efficiency of deception detection in concealed information test (CIT). During the CIT, participants were presented with a series of names and cities that served as target, probe, or irrelevant stimuli. In the guilty group, the probe stimuli were the participants' own names and hometown cities, and they were asked to deny this information. Our results revealed that probe items were associated with longer RT, larger SCR, slower HR, and higher oxyhemoglobin (HbO) concentration changes in the inferior prefrontal gyrus (IFG), middle frontal gyrus (MFG), and the superior frontal gyrus (SFG) compared with irrelevant items for participants in the guilty group but not in the innocent group. Furthermore, our results suggested that the combination of RT, SCR, HR, and fNIRS indicators could improve the deception detection efficiency to a very high area under the ROC curve (0.94) compared with any of the single indicators (0.74-0.89). The improved deception detection efficiency might be attributed to the reduction of random error and the diversiform underlying the psychophysiological mechanisms reflected by each indicator. These findings demonstrate a feasible way to improve the deception detection efficiency by using combined multiple indicators.

ABSTRACT

This study used longitudinal cross-lagged modeling to examine the contribution of theory of mind (ToM), executive function (EF) to children's lying development and of children's lying to ToM and EF development. Ninety-seven Chinese children (initial M age = 46 months, 47 boys) were tested three times approximately 4 months apart. Results showed that the diverse desire understanding and knowledge access understanding components of ToM, as well as the inhibitory control component of EF predicted the development of children's lying, while the diverse belief understanding and false belief understanding components of ToM, and the working memory component of EF did not predict development of children's lying. Meanwhile, children's lying predicted development of children's belief-emotion understanding components of ToM, but not any other ToM components, or EF components. These findings provide longitudinal evidence for the relation between ToM, EF, and children's lying during the preschool years.

ABSTRACT

Numerous studies have sought proof of whether people are genuinely honest by testing whether cognitive control mechanisms are recruited during honest and dishonest behaviors. The underlying assumption is: Deliberate behaviors require cognitive control to inhibit intuitive responses. However, cognitive control during honest and dishonest behaviors can be required for other reasons than deliberation. Across 58 neuroimaging studies (1,211 subjects), we investigated different forms of honest and dishonest behaviors and demonstrated that many brain regions previously implicated in dishonesty may reflect more general cognitive mechanisms. We argue that the motivational/volitional dimension is central to deliberation and provide evidence that motivated dishonest behaviors recruit the perigenual anterior cingulate cortex. This work questions the view that cognitive control is a hallmark of dishonesty.

ABSTRACT

The present study examines whether collaborative situations make individuals more dishonest in face-to-face settings. It also considers how this dishonesty unfolds over time. To address these questions, we employed a sequential dyadic die-rolling task in which two participants in a pair sitting face-to-face received a payoff only if both reported the same outcome when each one rolled their die. In each trial, one participant (role A) rolled a die first and reported the outcome. Then, the second participant (role B) was informed of A's reported number, rolled a die as well, and reported the outcome. If their reported outcomes were identical, both of them received a reward. We also included an individual condition in which an individual subject rolled a die twice and received a reward if he/she reported the same die-roll outcome. We found that B lied significantly more than participants in the individual condition, whereas A lied as much as participants in the individual condition. Furthermore, when collaborating, more and more participants (both A and B) became dishonest as the game progressed, whereas there was no such trend among participants in the individual condition. These findings provide evidence indicating that collaborative settings increase dishonesty and that this effect becomes more evident as the collaboration progress.

ABSTRACT

Scientific research on how children learn to tell lies has existed for more than a century. Earlier studies mainly focused on moral, social, and situational factors contributing to the development of lying. Researchers have only begun to explore the cognitive correlations of children's lying in the last two decades. Cognitive theories suggest that theory of mind (ToM) and executive function (EF) should be closely related to the development of lying since lying is, in essence, ToM and EF in action. Yet, findings from empirical studies are mixed. To address this issue, the current meta-analysis reviewed all prior literature that examined the relations between children's lying and ToM and/or between children's lying and EF. In total, 47 papers consisting of 5099 participants between 2 and 19 years of age were included, which yielded 74 effect sizes for ToM and 94 effect sizes for EF. Statistically significant but relatively small effects were found between children's lying and ToM (r = .17) and between lying and EF (r = .13). Furthermore, EF's correlation with children's initial lies was significantly smaller than its correlation with children's ability to maintain lies. This comprehensive meta-analysis provides a clear picture of the associations between children's ToM/EF and their lying behavior and confirms that ToM and EF indeed play a positive role in children's lying and its development.

ABSTRACT

This study aims to examine neural correlates of spontaneous deception in a non-competitive interpersonal situation, and the difference in neural correlates between spontaneous deception and instructed deception using functional near-infrared spectroscopy (fNIRS). We used a modified poker game in which participants freely decided whether sending a piece of truthful/deceptive information to other participants. In the instructed session, participants sent truthful/deceptive information per the instructions. In this non-competitive interpersonal situation in the orbitofrontal cortex (OFC) and dorsolateral prefrontal cortex (DLPFC), deception produced higher neural activities than truth-telling. In addition, spontaneous deception exhibited higher neural activities than instructed deception in the frontopolar area, DLPFC, and frontal eye fields. Spontaneous truth-telling produced higher neural activities than instructed truth-telling in frontal eye fields and frontopolar area. This study provides evidence about neural correlates of spontaneous deception during non-competitive interpersonal scenarios and the difference between spontaneous deception and instructed deception.

ABSTRACT

The feedback concealed information test (fCIT) is a novel variant of a CIT, which provides participants with feedback regarding their memory concealment performance during the CIT. Previous studies have found that feedback-related ERPs associated with feedback processing in the fCIT can accurately identify concealed information. However, it is still unknown whether the feedback influences the process and ERP signs of recognition during memory concealment, such as the recognition P300. To address this issue, the present study directly compared the recognition-based P300 in CITs with and without feedback. Results showed that the probe elicited a larger recognition P300 than irrelevants in both CITs with and without feedback, and there were no significant differences in recognition P300 between those two CITs. Moreover, the detection rate for recognition-based P300 in both CITs also had no significant difference. The feedback-related ERPs, especially feedback P300, continued to discriminate guilty and innocent subjects with AUCs well above the chance.

ABSTRACT

Although there is widespread acknowledgment that children acquire social and moral values during development via socialization processes, few plausible mechanisms have been systematically evaluated. In the present research, we examine the effectiveness of 1 potential mechanism: overheard conversations about the moral behavior of others. We examine this issue with reference to the important social value of honesty. Across 3 preregistered studies, preschool-age children in China (total N = 276) were presented with a version of the temptation resistance paradigm in which they were first given an opportunity to cheat by peeking at the answer in a guessing game and were then asked whether they had cheated. Study 1 included both 3- and 5-year-olds, and Studies 2 and 3 included 5-year-olds only. In Study 1 children were more likely to truthfully confess to peeking if they had previously overheard 2 adults say that another child's confession made them happy. An increase in truthful confessions was also seen in Study 2, even though this time the adult who asked about peeking had not been present for the overheard conversation. In Study 3, children were presented with an overheard conversation that lacked any emotion-related language, and the effect was seen once again. Taken together, these findings suggest that overheard conversations can be used to promote truth telling. More broadly, the findings suggest that children realize the attitudes adults express about others can have implications for their own behavior and can identify these attitudes, even when they are not the target of the communication.

ABSTRACT

Neuroimaging technologies have improved our understanding of deception and also exhibit their potential in revealing the origins of its neural mechanism. In this study, a quantitative power analysis method that uses the Welch power spectrum estimation of functional near-infrared spectroscopy (fNIRS) signals was proposed to examine the brain activation difference between the spontaneous deceptive behavior and controlled behavior. The power value produced by the model was applied to quantify the activity energy of brain regions, which can serve as a neuromarker for deception detection. Interestingly, the power analysis results generated from the Welch spectrum estimation method demonstrated that the spontaneous deceptive behavior elicited significantly higher power than that from the controlled behavior in the prefrontal cortex. Meanwhile, the power findings also showed significant difference between the spontaneous deceptive behavior and controlled behavior, indicating that the reward system was only involved in the deception. The proposed power analysis method for processing fNIRS data provides us an additional insight to understand the cognitive mechanism of deception.

ABSTRACT

While previous studies have shown that East-West cultural differences exist in processing different emotional stimuli, potential subcultural differences within a large cultural group are not well understood. In this study, we examined subcultural differences in the event-related potential (ERP) modulations in the brain, during processing social positive and non-social positive stimuli among 21 Han Chinese and 21 Uygur Chinese. Results showed that the magnitudes of P2, N2, and late positive potential (LPP) were larger in Uygur Chinese than in Han Chinese. For social positive stimuli, the P2 and LPP 300-600 were larger in Uygur Chinese than in Han Chinese. However, there was no significant difference in non-social positive stimuli. These results indicated that social positive emotions were more prioritized in emotional processing among Uygur Chinese than Han Chinese. These findings contribute to the growing literature on subcultural differences in processing different types of positive stimuli.

ABSTRACT

Previous studies have found that "disgust-sensitive" individuals have negative attitudes toward gay and lesbian people, but the underlying mechanisms for such attitudes remain unclear. Based on moral foundations theory, the current paper assumes that the relationship between disgust sensitivity and attitudes toward homosexuality are mediated by moral foundations. In order to test this assumption, the current authors examined the questionnaire answers from a total of 452 Chinese undergraduates who participated in this study. The results showed that disgust sensitivity was positively correlated with negative attitudes toward homosexuality, and positively correlated with moral concerns in five domains (care, fairness, loyalty, authority, and sanctity). Authority and sanctity were both associated with attitudes toward homosexuality, while only sanctity mediated the relationship between disgust sensitivity and attitudes toward homosexuality. Overall, the results suggest that considering moral foundations (especially sanctity) may lend more insight to the associations between disgust sensitivity and negative attitudes toward gay and lesbian people.

ABSTRACT

The present study examined the role of executive function in lying for children with autism spectrum disorder (ASD). The temptation resistance paradigm was used to elicit children's self-protective lies and the Hide-and-seek task was used to elicit children's self-benefiting lies. Results showed that children with ASD told fewer lies in the two deception tasks compared to children with intellectual disability (ID) and typically developing (TD) children. Furthermore, children with ASD's lying were positively correlated with their working memory, but not with their theory of mind. These findings demonstrate that the mechanisms underlying deception for children with ASD are distinct from that of TD children.
