Deception is an essential part of children\'s moral development. Previous developmental studies have shown that children start to deceive at the age of 3 years, and as age increased to 5 years, almost all children were able to deceive for their own benefit. Although behavioral studies have indicated that the emergence and development of deception are related to cognitive abilities, their neural correlates remain poorly understood. Therefore, the present study examined the neural correlates underlying deception in preschool-aged children (N = 89, 44% boys, age 3.13 to 5.96 years, Han Chinese) using functional near-infrared spectroscopy. A modified hide-and-seek paradigm was applied to elicit deceptive and truth-telling behaviors. The results showed that activation of bilateral dorsolateral prefrontal cortex was positively associated with the tendency to deceive an opponent in a competitive game in the 3-year-olds. In addition, 3-year-olds who showed a high tendency to deceive showed the same brain activation in the frontopolar area as 5-year-olds did when engaged in deception, whereas no such effect was found in 3-year-olds who never engaged in deception. These findings underscore the link between preschoolers\' deception and prefrontal cortex function.

Most studies on deception in soccer penalty kicks have focused on the deceptive actions used by penalty takers. However, it is worth noting that deception can also be played out by goalkeepers. To examine the effectiveness of goalkeepers\' deceptive actions in professional competition, we analysed 714 penalty kicks taken during matches in the English Premier League and German Bundesliga, spanning the seasons from 2016-2017 to 2019-2020. We scored whether goalkeepers used deception, and if so, what type of deception, the outcome of the penalty and the kicking strategy of the penalty taker. The results showed that goalkeepers used deception in half of the penalty kicks, resulting in significantly less goals compared to penalties without deception. This advantage was similar for the different types of deception, but larger when penalty takers paid attention to goalkeepers. We propose that the deceptive actions by goalkeepers are effective, mainly because it leads the penalty taker to lose focus. The practical implications of these findings are discussed for both goalkeepers and penalty takers.

This cross-sectional study investigated the reasons behind academic cheating in a cohort of nursing students in Saudi Arabia. The study involved 482 nursing students from two government universities in Riyadh. We used a newly developed self-reported questionnaire called the Reasons for Cheating Scale (RCS) to collect data. The highest-scoring reasons for academic cheating in the study population included the desire to obtain high grades, encouragement from friends to cheat, and the perception that exams were too difficult. Male students scored significantly higher than female students for reasons such as not understanding the course material, unclear test questions and instructions, pressure from families to excel, difficulty of the course material, and ignorance of effective study methods (P < 0.05). Age also had a role, as students aged 15-20 years had significantly higher scores for the item \"Exams are too hard\", whereas those aged ≥25 years had higher scores for \"Difficulty of the course material\" (P < 0.05). Additionally, students in the preparatory year had significantly higher scores than those in other years for reasons such as difficult exams, unclear test questions and instructions, fear of failing, difficulty of the course material, and the desire to please their families (P < 0.05). Overall, the desire to obtain high grades emerged as the main reason for academic cheating in our cohort of nursing students in Saudi Arabia. The findings suggest that sociodemographic characteristics, including sex, age, and academic year, should be considered when addressing the issue of cheating among nursing students.

Due to differences in social communication and cognitive functioning, autistic adults may have greater difficulty engaging in and detecting deception compared to neurotypical adults. Consequently, autistic adults may experience strained social relationships or face increased risk of victimization. It is therefore crucial that research investigates the psychological mechanisms that are responsible for autistic adults\' difficulties in the deception process in order to inform interventions required to reduce risk. However, weaknesses of extant research exploring deception in autism include a heavy focus on children and limited theoretical exploration of underlying psychological mechanisms. To address these weaknesses, this review aims to introduce a system-level theoretical framework to the study of deception in autistic adulthood: The Brunswik Lens Model of Deception. Here, we provide a comprehensive account of how autism may influence all processes involved in deception, including: Choosing to Lie (1), Producing Deception Cues (2), Perceiving Deception Cues (3), and Making the Veracity Decision (4). This review also offers evidence-based, theoretical predictions and testable hypotheses concerning how autistic and neurotypical adults\' behavior may differ at each stage in the deception process. The call to organize future research in relation to a joint theoretical perspective will encourage the field to make substantive, theoretically motivated progress toward the development of a comprehensive model of deception in autistic adulthood. Moreover, the utilization of the Brunswik Lens Model of Deception in future autism research may assist in the development of interventions to help protect autistic adults against manipulation and victimization.

In this paper, I discuss the ethical issues related to deception in human subject research in terms of honesty. First, I introduce the background and suggest the conception of honesty that understands it as involving respect for the right not to be deceived (RND). Next, I examine several ways to address the ethical issues of deceptive elements in the human subject research and show why they fail to adequately meet the demand of honesty. I focus on how to make an honest research plan and examine after participation and before participation phases in turn. Then I conclude by suggesting possible strategies to minimize dishonesty in human subject research.

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.

Research is lacking regarding adults\' ability to determine whether children\'s drawings are based on an experience or not. Drawings are useful in professional settings to alleviate linguistic demands, facilitate memory, and have been used as evidence. Determining the accuracy of veracity assessments of children\'s drawings would inform professionals regarding their use as evidence of experiences. Twenty-eight children (14 younger, Mage = 7.53 years, SDage = 1.19; 14 older, Mage = 11.67 years, SD = 1.27) produced drawings of two events: one staged experienced, and one narrative-based not experienced event. Fifty (Study 1, Mage = 23.72 years, SDage = 9.70) and 63 (Study 2, Mage = 25.92, SDage = 12.79) adults indicated whether each drawing was based on experience and their confidence in each assessment. In Study 2, additional drawing quality assessments were collected. Results indicated that adults were more accurate at distinguishing experienced than not experienced drawings for older artists. An inverse relationship was observed between confidence and accuracy-participants were more confident when they were inaccurate, especially for younger artists. Drawing quality improved with age and for drawings of experienced events. Adults tended to rate drawings of higher quality as resulting from experience leading to the highest accuracy for drawings from older artists that were based on experience. Overall, results suggest that there may be some features of drawings that allow for above chance levels of accuracy (up to 75%). However, rates are not high enough across assessments (M = 53.93%, range: 39%-75%) to reliably use them as indicators of experience.

This study examined a proposed model of relations among lie-telling self-efficacy, moral disengagement, and willingness to tell antisocial lies among children and adolescents. Children and adolescents aged 6 to 15 years completed measures of lie-telling self-efficacy and moral disengagement. They also read vignettes about a character committing a transgression and telling a lie to conceal the transgression. For each vignette, children and adolescents made a hypothetical decision about telling the truth or a lie if they were in the character\'s position to assess their lie-telling propensity. Lie-telling self-efficacy was related to willingness to tell lies, and this relationship was mediated by moral disengagement. Children and adolescents with higher lie-telling self-efficacy had higher moral disengagement, and those who had higher moral disengagement were more willing to tell antisocial lies. Overall, results support Bandura\'s social cognitive theory as a framework for understanding the psychosocial mechanisms underlying attitudes toward lie-telling. Moreover, these findings suggest that interventions to address problematic lie-telling behavior should focus on children\'s and adolescents\' use of moral disengagement mechanisms.
