An EEG Dataset of Neural Signatures in a Competitive Two-Player Game Encouraging Deceptive Behavior.

Studying deception is vital for understanding decision-making and social dynamics. Recent EEG research has deepened insights into the brain mechanisms behind deception. Standard methods in this field often rely on memory, are vulnerable to countermeasures, yield false positives, and lack real-world relevance. Here, we present a comprehensive dataset from an EEG-monitored competitive, two-player card game designed to elicit authentic deception behavior. Our extensive dataset contains EEG data from 12 pairs (N = 24 participants with role switching), controlled for age, gender, and risk-taking, with detailed labels and annotations. The dataset combines standard event-related potential and microstate analyses with state-of-the-art decoding approaches of four scenarios: spontaneous/instructed truth-telling and lying. This demonstrates game-based methods' efficacy in studying deception and sets a benchmark for future research. Overall, our dataset represents a unique resource with applications in cognitive neuroscience and related fields for studying deception, competitive behavior, decision-making, inter-brain synchrony, and benchmarking of decoding frameworks in a difficult, high-level cognitive task.

Perceptions of Cheating Among Students of Health Professions.

For many decades, academic cheating has been prevalent across many institutions and majors. This problem has been exacerbated by new technology that has increased opportunities for students to access and use information dishonestly. There is fear amongst faculty that dishonesty in the academic world could negatively impact professionals in their future careers. The greater prevalence of cheating may be related to students misunderstanding what constitutes cheating. To better understand students' perceptions of cheating, a group of faculty surveyed students across 11 academic programs at a college of health professions using a slightly modified version of a validated tool via an online platform. Data about cheating perceptions were collected from more than 400 students. Although most respondents agreed that cheating is wrong, some were open to explanations of innocence related to possible cheating scenarios. Also, most respondents did not agree that a person who cheats is an unethical person. These findings suggest that students believe cheating can occur unintentionally. Although the findings support that more education about academic dishonesty would be valuable, this study can inform efforts to develop more targeted education and interventions to reduce cheating behaviors.

Academic cheating in early childhood: Role of age, gender, personality, and self-efficacy.

The current study investigated the association of children's age, gender, ethnicity, Big Five personality traits, and self-efficacy with their academic cheating behaviors. Academic cheating is a rampant problem that has been documented in adolescents and adults for nearly a century, but our understanding of the early development and factors influencing academic cheating is still weak. Using Zoom, the current study recruited children aged 4 to 12 years (N = 388), measured their cheating behaviors through six tasks simulating academic testing scenarios, and assessed their Big Five personality traits and self-efficacy through a modified Berkeley Puppet Interview paradigm, as well as age and gender. We found that children cheated significantly less with increased age and that boys cheated significantly more than girls. However, neither Big Five personality traits nor self-efficacy were significantly correlated with children's cheating. These findings suggest that academic cheating is a developing issue from early to middle childhood and that factors such as gender socialization may play a role in such development. Personal characteristics such as personality traits and self-efficacy may undergo additional development before their associations with cheating become robust, as reported in the adult literature.

Elementary school-aged children's perceptions of academic dishonesty: Definitions and moral evaluations of cheating behaviors in school.

A total of 76 children (Mage = 9 years 5 months, SD = 2.22 years) participated in a structured interview about their experiences with and knowledge of academic dishonesty. Overall, 27% of the sample reported having cheated in school. Most of these children were 10 to 13 years old, and the most prevalent form of cheating behavior reported was using forbidden materials during a test. Children's age group was a significant positive predictor of their reported cheating history; however, no significant difference was found between children's gender and engagement with cheating. Children's moral evaluations of cheating did not predict their reported cheating history, nor did children's parents' cheating history. Vignette type (cheating vs. non-cheating), age group, and the interaction between vignette type and age group were significant predictors of children's ability to accurately identify behaviors that constitute cheating. Children rated cheating behaviors as significantly less moral than non-cheating behaviors. Overall, the current results provide insight into what forms of cheating behavior children engage in at the elementary school-age level.

Participant Fraud in Virtual Qualitative Substance Use Research: Recommendations and Considerations for Detection and Prevention Based on a Case Study.

Background: The COVID-19 pandemic has accelerated and amplified the use of virtual research methods. While online research has several advantages, it also provides greater opportunity for individuals to misrepresent their identities to fraudulently participate in research for financial gain. Participant deception and fraud have become a growing concern for virtual research. Reports of deception and preventative strategies have been discussed within online quantitative research, particularly survey studies. Though, there is a dearth of literature surrounding these issues pertaining to qualitative studies, particularly within substance use research. Results: In this commentary, we detail an unforeseen case study of several individuals who appeared to deliberately misrepresent their identities and information during participation in a virtual synchronous qualitative substance use study. Through our experiences, we offer strategies to detect and prevent participant deception and fraud, as well as challenges to consider when implementing these approaches. Conclusions: Without general awareness and protective measures, the integrity of virtual research methods remains vulnerable to inaccuracy. As online research continues to expand, it is essential to proactively design innovative solutions to safeguard future studies against increasingly sophisticated deception and fraud.

Can Media Literacy Intervention Improve Fake News Credibility Assessment? A Meta-Analysis.

Fake news impacts individuals' behavior and decision-making while also disrupting political processes, perceptions of medical advice, and societal trends. Improving individuals' ability to accurately assess fake news can reduce its harmful effects. However, previous research on media literacy interventions designed for improving fake news credibility assessments has yielded inconsistent results. We systematically collected 33 independent studies and performed a meta-analysis to examine the effects of media literacy interventions on assessing fake news credibility (n = 36,256). The results showed that media literacy interventions significantly improved fake news credibility assessments (Hedges' g = 0.53, 95% confidence interval [0.29-0.78], p < 0.001). Gaming interventions were the most effective intervention form. Conversely, the intervention channel, outcome measurement, and subject characteristics (age, gender, and country development level) did not influence the intervention effects.

Don't be a rat: An investigation of the taboo against reporting other students for cheating.

This research examines barriers to reporting academic dishonesty in early adulthood (Study 1; N = 92) and adolescence (Study 2; N = 137). Participants were asked to describe a recent time they observed a peer cheating and to reflect on their decision about whether to report the cheating. They also responded to hypothetical scenarios about observing typical cheating actions, and the presence of social motives (e.g., whether people who report tend to gain reputations for being snitches) was manipulated in each scenario. Even though participants judged reporting to be the morally right thing to do, doing so was rare and approval for it was low, especially in adolescence. Participants also tended to say they would rather be friends with people who do not report cheaters than with those who do. Participants reasoned about a variety of social concerns to support their judgments about reporting (e.g., concern about their relationship with the cheater, concerns for others' welfare), and the manipulated social motives in the hypothetical scenarios significantly influenced judgments about reporting. These findings inform our understanding of the social dynamics that contribute to decisions about policing academic honesty.

Detecting lies through others' eyes: Children use perceptual access cues to evaluate listeners' beliefs about informants' deception.

Children are often third-party observers of conversations between informants and receivers. Although 5- and 6-year-olds can identify and reject informants' false testimony, it remains unclear whether they expect others to do the same. Accurately assessing others' impressions of informants and their testimony in a conversational setting is essential for children's navigation of the social world. Using a novel second-order lie detection task, the current study examined whether 4- to 7-year-olds (N = 74; Mage = 69 months) take receivers' epistemic states into account when predicting whether a receiver would think an informant is truthful or deceptive. We pitted children's firsthand observations of reality against informants' false testimony while manipulating receivers' perceptual access to a sticker-hiding event. Results showed that when the receiver had perceptual access and was knowledgeable, children predicted that the receiver would think the informant is lying. Critically, when the receiver lacked perceptual access and was ignorant, children were significantly more likely to predict that the receiver would think the informant is telling the truth. Second-order theory of mind and executive function strengthened this effect. Findings are interpreted using a dual-process framework and provide new insights into children's understanding of others' selective trust and susceptibility to deception.

Cognitive empathy boosts honesty in children and young adolescents.

Children and young adolescents often tend to behave dishonestly in order to serve their self-interests. This study focused on how empathic abilities affect children's tendency to deceive others. Deception is the act of causing others to form a false belief to get them to act in a way that serves the deceiver's interests. As such, it requires the ability to predict how others might use the provided information. In two experiments, 274 participants (aged 10-16 years) played a game in which they could send a deceptive message to another participant to boost their own payoff at the other player's expense. We measured participants' cognitive and emotional empathy using different measures. We found that a measure of cognitive empathy, namely the fantasy scale, was associated with less deception of another player when that other player was not identified and was presented only as "Player B." However, when Player B was identified by name, empathy did not predict deception. In such cases, the only factors affecting deception rates were the gain for the participant (higher possible gains lead to more deception) and loss to the other player (higher possible losses lead to less deception). Overall, the findings suggest that even by 11 years of age, children can understand the impact of their unethical behavior on another child and adjust their actions accordingly. However, when the other child is not identified, children need to possess high levels of cognitive empathy toward imagined individuals to resist the temptation to deceive the other child.

Younger and Older Adults' Health Lies to Close Others.

OBJECTIVES: Lying is a common social behavior; however, there is limited research on lying about health and if this differs into later life. This study sought to explore age differences in the frequency of and motivations behind telling health-related lies and if lying differs within romantic and parent/child relationships. METHODS: Younger (N = 158) and older adults (N = 149) reported how often they told general health-related lies, how often they lied about health to their romantic partner and parent or adult child, and why they told health lies. RESULTS: Compared with older adults, younger adults lied more frequently to conceal sickness and pain as well as to feign sickness. Younger adults also told more health lies to their parent than their romantic partner, but older adults lied to their adult child and partner at similar rates. Younger adults reported lying more about their health because they felt ashamed or embarrassed and they worried about what others would think of them compared with older adults. DISCUSSION: These results suggest that health-related honesty may increase in later life and that younger and older adults differ in why they tell health lies. Implications for psychological theory on lying about one's health and health interventions are discussed.

Unveiling the efficacy of the feedback concealed information test in collaborative crime detection.

Collaborative crime poses severe social hazards. In collaborative crime scenarios, previous studies have indicated that perpetrators' collaborative encoding can impair the detection efficiency of P300-based complex trial protocols due to the collaborative encoding deficit. The feedback concealed information test (fCIT), a unique variation of the concealed information test, provides participants with feedback on how well they conceal information from memory. The fCIT, which has proven to be highly efficient, detects concealed information using recognition P300 along with feedback-related event-related potentials, and reflects the subject's motivation to conceal. However, no studies have examined the fCIT's effectiveness in identifying collaborative criminals. We propose that the fCIT's efficiency persists in cases of collaborative crime and test this hypothesis using a sample of 48 participants. The participants in the collaborative groups were instructed to have hushed conversations about theft to simulate the collaborative crime process. Subsequently, they completed the fCIT. The findings indicate a significant decline in recognition P300's detection efficiency when participants committed crimes collaboratively. Nevertheless, the detection efficiency of feedback P300 and feedback-related negativity remained high. This study's outcomes illustrate the capacity of the fCIT to detect perpetrators involved in collaborative crime.

Security load frequency control model of interconnected power system based on deception attack.

The interconnected power system connects the power grids of different regions through transmission lines, achieving power interconnection and resource sharing. However, data is transmitted through open power networks and is more susceptible to network attacks. To improve the stability of interconnected power systems under deception attacks, three scenarios of system security load frequency control were studied. Based on the construction of a dynamic model of load frequency control, an event-triggered strategy was used to reduce the communication frequency between nodes, resulting in a reduction in the amount of network transmission data. A sliding mode controller was constructed to solve the problem of event-triggered sliding mode security load frequency control. Elastic event-triggered sliding mode load frequency control for interconnected power systems under mixed attacks. The simulation results showed that using the load frequency control model triggered by events, the load frequency deviation of the interconnected power system can be stabilized at around 12 seconds, effectively saving the cost of network resources. Under the regulation of the load frequency control model based on sliding mode control, the interconnected power system stabilized in 10 seconds, reducing the load of network transmission. The elastic event-triggered sliding mode load frequency control model can ensure stable transmission of power data under various attacks and has good anti-interference performance. The results of this study have played an important role in achieving the stability of power resource supply. Compared with previous studies on individual power systems, this study solves the attack problem of interconnected power systems and considers the frequency control problem of system security loads under mixed attacks, enabling the system to recover stability faster.

When are people more open to cheating? Economic inequality makes people expect more everyday unethical behavior.

Economic inequality has been found to be associated with increased unethical behavior and an increased acceptance of unethical behavior. In this paper we explored whether higher amounts of perceived inequality lead to an increase in the expectation of unethical behavior. We tested whether people would say that they themselves would engage in more unethical behavior in a context of high compared to low inequality. We find evidence for this hypothesis in 3 of 4 studies (n = 3,038). An internal meta-analysis shows a small but significant effect. Such increased expectations that oneself will behave unethically likely has consequences for societal trust and functioning.

Self-efficacy and cheating among young children.

This research, comprising three preregistered studies, investigated the link between self-efficacy and cheating on an academic test in 5- and 6-year-old children. Study 1 assessed children's general self-efficacy and found it to be unrelated to their cheating behavior. Study 2 assessed task-specific self-efficacy, which was not found to be associated with cheating. In Study 3, children were randomly assigned to either an experimental group, which received brief positive feedback on task-specific self-efficacy, or a control group, which received no feedback. The experimental group demonstrated significantly less cheating. These findings, for the first time, identify a specific connection between young children's self-efficacy and academic dishonesty and suggest that positive feedback on task-specific efficacy could be a simple effective strategy for fostering academic integrity early on.

Hydrogen Water: Extra Healthy or a Hoax?-A Systematic Review.

Hydrogen-rich water (HRW) has emerged as a novel approach in the field of health and wellness. It is believed to have therapeutic antioxidant properties that can neutralize harmful free radicals in the human body. It has also been shown to be beneficial in mitigating oxidative stress-induced damage through its anti-inflammatory and anti-apoptotic pathways. We aim to conduct a systematic review to evaluate the potential benefits of hydrogen-rich water. The review protocol was uploaded on PROSPERO. After the initial search criteria, the articles were reviewed by two blinded investigators, and a total of 25 articles were included in the systematic review. The potential benefits of hydrogen-rich water on various aspects of health, including exercise capacity, physical endurance, liver function, cardiovascular disease, mental health, COVID-19, oxidative stress, and anti-aging research, are a subject of growing interest and ongoing research. Although preliminary results in clinical trials and studies are encouraging, further research with larger sample sizes and rigorous methodologies is needed to substantiate these findings. Current research needs to fully explain the mechanisms behind the potential benefits of hydrogen-rich water. Continued scientific exploration will provide valuable insights into the potential of hydrogen-rich water as an adjunctive therapeutic approach in the future.

Individual Responsibility Around Deepfakes: It's No Laughing Matter.

The objectives of this research were to examine the contextual factors that impact individual's interpretation of their responsibility in the context of Deepfake videos. Using a test/retest methodology, a total of 1,023 respondents participated in a Deepfake survey instrument which measured perceptions of individual responsibility with respect to Deepfakes, individual concern with Deepfakes, and humorous perception of Deepfakes. The results of the study found that individual responsibility is negatively related to individual concern, indicating the externalization of responsibility for difficult to detect fake online videos designed to be convincing. Further, humorous perception and age impact the participants perception of individual responsibility. Younger participants were more likely to find Deepfakes humorous and this increased their perception of their own responsibility, potentially exposing them to greater harm from malicious Deepfakes.

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.

Dark personality traits and deception, and the short dark tetrad (SD4) as integrity screening instrument.

Dark personality traits (Machiavellianism, Narcissism, Psychopathy, and Sadism) have been associated with aversive, unethical, and criminal conduct. Concise measurement tools such as the Short Dark Tetrad (SD4) are popular, because they lend themselves as screening instruments. As such, the scores on these scales are used in various decision-making contexts, and they can have considerable effects on the lives of people who display an unfortunate scoring pattern. The present study explored to what extent high SD4 scores are actually predictive of deceptive behaviour in a matrix puzzle task, in a general community sample (N = 751). Results indicated that 9.9% of participants lied, that is, exaggerated their performance on the matrix task, hoping to increase their likelihood of financial reward. These cheating participants scored higher on all four dark traits. Nonetheless, the overlap between SD4 distributions made it impossible to determine cut-off scores in an attempt to consider scores as actual predictors of deception proneness. When framed in likelihoods, some scores can be diagnostic of deception proneness. Particularly in the context of statement validity assessment, characterized by tools with modest to poor accuracy, SD4 scores may add to diagnostic accuracy.

Effects of Ziprasidone or Haloperidol on Theory of Mind in Patients With Schizophrenia: A 16-week Pilot Trial.

OBJECTIVES: Schizophrenia is associated with impairment in theory of mind (ToM), which is defined as the ability to make judgments about mental states and is related to medial prefrontal cortical activity. Ziprasidone, but not haloperidol, is known to have a protective effect in the medial prefrontal cortex. Thus, we hypothesized that these 2 drugs would have different efficacy in improving ToM task performance in patients with schizophrenia. METHODS: Patients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnosis of schizophrenia matched for sex, duration of illness, and education were randomized to receive ziprasidone (n=30) or haloperidol (n=30). All patients were assessed using the Positive and Negative Syndrome Scale and the Personal and Social Functioning Scale. ToM was assessed using a first-order false belief task, a second-order false belief task, the faux-pas task, and the Reading the Mind in the Eyes Task, in order of developmental complexity and difficulty. The primary outcome was change in ToM performance from baseline to 16 weeks of treatment. RESULTS: For the first-order false belief task, there were no significant differences between the groups (P>0.05). For the second-order false belief task, the interaction effect was significant (P<0.05), and the simple effect of time showed a significant difference only in the ziprasidone group (P<0.001). For the faux-pas task, the interaction effect was not significant (P>0.05). For the Reading the Mind in the Eyes Task, the interaction effect was significant (P<0.05), and the simple effect of time showed a significant difference only in the ziprasidone group (P<0.001). The Positive and Negative Syndrome Scale results were similar between the groups. The ziprasidone group performed better than the haloperidol group on the Personal and Social Functioning Scale. There were no major safety concerns or adverse events. CONCLUSIONS: The findings of this study suggest that ziprasidone could improve ToM and might be superior to haloperidol for improving complex ToM as well as personal and social functioning in patients with schizophrenia.
