Lying is a pervasive human behavior. Evidence to date suggests that from the age of 42 months onward, children become increasingly capable of telling lies in various social situations. However, there is limited experimental evidence regarding whether very young children will tell lies spontaneously. The present study investigated the emergence of lying in very young children. Sixty-five 2- to 3-year-olds were asked not to peek at a toy when the experimenter was not looking. The majority of children (80%) transgressed and peeked at the toy. When asked whether they had peeked at the toy, most 2-year-old peekers were honest and confessed to their peeking, but with increased age, more peekers denied peeking and thus lied. However, when asked follow-up questions that assessed their ability to maintain their initial lies, most children failed to conceal their lie by pretending to be ignorant of the toy’s identity. Additionally, after controlling for age, children’s executive functioning skills significantly predicted young children’s tendency to lie. These findings suggest that children begin to tell lies at a very young age.
The present investigation examined 8- to 16-year-olds’ tendency to lie, the sophistication of their lies, and related cognitive factors. Participants were left alone and asked not to look at the answers to a test, but the majority peeked. The researcher then asked a series of questions to examine whether the participants would lie about their cheating and, if they did lie, evaluate the sophistication of their lies. Additionally, participants completed measures of working memory, inhibitory control, and planning skills. Results revealed that the sophistication of 8- to 16-year-olds’ lies, but not their decision to lie, was significantly related to executive functioning skills.
Young children’s ability to tell a strategic lie by making it consistent with the physical evidence of their transgression was investigated along with the sociocognitive correlates of such lie-telling behaviors. In Experiment 1, 247 Chinese children between 3 and 5 years of age (126 boys) were left alone in a room and asked not to lift a cup to see the contents. If children lifted up the cup, the contents would be spilled and evidence of their transgression would be left behind. Upon returning to the room, the experimenter asked children whether they peeked and how the contents of the cup ended up on the table. Experiment 1 revealed that young children are able to tell strategic lies to be consistent with the physical evidence by about 4 or 5 years of age, and this ability increases in sophistication with age. Experiment 2, which included 252 Chinese 4-year-olds (127 boys), identified 2 sociocognitive factors related to children’s ability to tell strategic lies. Specifically, both children’s theory-of-mind understanding and inhibitory control skills were significantly related to their ability to tell strategic lies in the face of physical evidence. The present investigation reveals that contrary to the prevailing views, even young children are able to tell strategic lies in some contexts.
The classic moral stories have been used extensively to teach children about the consequences of lying and the virtue of honesty. Despite their widespread use, there is no evidence whether these stories actually promote honesty in children. This study compared the effectiveness of four classic moral stories in promoting honesty in 3- to 7-year-olds. Surprisingly, the stories of "Pinocchio" and "The Boy Who Cried Wolf" failed to reduce lying in children. In contrast, the apocryphal story of "George Washington and the Cherry Tree" significantly increased truth telling. Further results suggest that the reason for the difference in honesty-promoting effectiveness between the "George Washington" story and the other stories was that the former emphasizes the positive consequences of honesty, whereas the latter focus on the negative consequences of dishonesty. When the "George Washington" story was altered to focus on the negative consequences of dishonesty, it too failed to promote honesty in children.
The present study examined the developmental origin of 'blue lies', a pervasive form of lying in the adult world that is told purportedly to benefit a collective. Seven, 9-, and 11-year-old Chinese children were surreptitiously placed in a real-life situation where they decided whether to lie to conceal their group's cheating behavior. Children were also assessed in terms of their willingness in hypothetical situations to endorse lying or truth-telling that benefits a collective but at the same time harms an individual. Results showed that as age increased, children became more inclined to endorse lying in the name of the collective good, and to tell lies for their group themselves. Furthermore, children's endorsement about blue lies in hypothetical situations predicted their actual lying behavior.
Study Type – Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? The reported discordance between staging on transurethral bladder resection and on radical cystectomy pathology in the literature ranges from 20 to 80%.Correct staging in bladder cancer has direct implications for its management. The upstaging from organ‐confined (OC) to non‐organ‐confined (nOC) disease has been reported in 40% of cases. Lymphovascular invasion (LVI) is a factor known to be associated with poor clinical outcome. Pathological upstaging was observed in our cohort in 40% of cases and most cases (80%) were upstaged from OC to nOC disease. During the study period the frequency of upstaging observed increased. We found LVI (hazard ratio [HR]= 5.07, 95% CI = 3.0–8.3, P < 0.001) and any histological variant variant (HR = 2.77, 95% CI = 1.6–4.8, P < 0.001) to be strong independent predictors of upstaging. Patients with clinical T2 bladder cancer found with upstaging at the time of radical cystectomy had a poorer outcome than patients with no upstaging. Identification of patients at high risk of upstaging at radical cystectomy is key to improving their management and outcome. OBJECTIVES To analyse the details of bladder cancer (BC) staging in a large combined radical cystectomy (RC) database from two academic centres. To study rate and time trends, as well as risk factors for upstaging, especially clinical factors associated with staging errors after RC. PATIENTS AND METHODS Characteristics of patients undergoing RC at University Health Network, Toronto, Canada (1992–2010) and University of Turku, Turku, Finland (1986–2005) were analysed. RESULTS Among 602 patients undergoing RC, 306 (51%) had a discordance in clinical and pathological stages. Upstaging occurred in 240 (40%) patients and 192 (32%) patients were upstaged from organ‐confined (OC) to non‐organ‐confined (nOC) disease. During the study period, upstaging became more common in both centres. In multivariate analyses, T2 disease at initial presentation (P= 0.001, odds ratio [OR]= 2.62, 95% confidence interval [CI]: 1.44–4.77), high grade disease (P= 0.01, OR = 2.85, 95% CI: 1.21–6.7), lymphovascular invasion (LVI) (P < 0.001, OR = 5.17, 95% CI: 3.48–7.68), female gender (P= 0.038, OR = 0.6, 95% CI: 0.38–0.97, and histological variants (P < 0.001, OR = 2.77, 95% CI: 1.6–4.8) were associated with a risk of upstaging from OC to nOC disease. Upstaged patients had worse survival rates than patients with correct staging. This was especially significant among patients with carcinoma invading bladder muscle before undergoing RC (16% vs 46% 10‐year disease‐specific mortality, P < 0.001). CONCLUSIONS Upstaging is a common problem and unfortunately no improvements have been observed during the last two decades. LVI and the presence of histological variants are strong predictors of upstaging at the time of RC. Pathologists should be encouraged to report LVI and any histological variant at the time of TURBT.
Techniques commonly used to increase truth-telling in most North American jurisdiction courts include: requiring witnesses to discuss the morality of truth-and lie-telling and to promise to tell the truth prior to testifying. While promising to tell the truth successfully decreases younger children's lie-telling, the influence of discussing the morality of honesty and promising to tell the truth on adolescents' statements has remained unexamined. In Experiment 1, 108 8-to 16-yearolds were left alone in the room and were asked not to peek at the answers to a test. The majority of participants peeked at the test answers and then lied about their transgression. More importantly participants were 8 times more likely to change their response from a lie to the truth after promising to tell the truth. Experiment 2 confirmed that the results of Experiment 1 were not solely due to repeated questioning or the moral discussion of truth-and lie-telling. These results suggest that while promising to tell the truth influences the truth-telling behaviors of adolescents, a moral discussion of truth and lies does not. Legal implications are discussed.Promoting truth and honesty within the justice system has been the focus of many studies over the past decade (e.g
