Autistic children and adolescents often have greater difficulty engaging in deception than their non-autistic peers. However, deception in autistic adulthood has received little attention to date. This study examined whether autistic and non-autistic adults differed in their inclination to lie in everyday situations and the factors that underpin…

Including robots in children's lives calls for reflection on the psychological and moral aspects of such relationships, especially with respect to children's ability to differentiate intentional from unintentional false statements, that is, lies from mistakes. This ability calls for an understanding of an interlocutor's intentions. This study…

Lying is a prevalent and normative behavior in young children. Conceptually, it is strongly linked with children's theory-of-mind development. However, empirical studies show that the link between children's lying and theory-of-mind is heterogeneous. This study examined whether parental control and parental warmth moderate the link between…

Lies and irony are paradigmatic examples of nonliteral communication; many deaf children and even adults have difficulty in understanding them. The present study assessed the understanding of lies and irony in 96 adolescents living in Spain in urban settings (58 deaf participants, 38 hearing participants; 10-19 years old). We investigated whether…

Children make choices between generosity and greed every day. Often they must also choose between confession or denial of antisocial acts like greed, thereby displaying either honesty or hypocrisy. Such choices pose cognitive challenges that, in theory, might reflect children's developing social-cognitions and affect their daily social lives and…

The development of a mind-reading ability, known as theory-of-mind (ToM), has been recognized as following a universal process, but the age at which the false-belief task is passed has been reported to have wide inter-group variabilities. Japanese children have been reported to acquire a false-belief understanding at a slightly older age than…

Identifying correlates of aggressive behavior in children might help to find potential candidates for interventions in aggression reduction. While some previous studies found that children's Theory of Mind (ToM) and inhibitory control (IC) correlate with aggressive behavior, others did not confirm this relation. One explanation for these mixed…

The ability to deceive is a key milestone in social cognitive development for typically developing individuals. In this scoping review, we systematically searched the literature to summarise research on deceptive behaviour in autism and identify gaps in knowledge. Across the 28 studies identified, three main themes were synthesised, with seven…

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…

To successfully pull a practical joke on someone, children need to understand that their victims do not know what they themselves know, be able to intentionally manipulate others' beliefs, and maintain a straight face to safeguard the integrity of the joke. This study examined the relationship between children's developing theory of mind (ToM),…

Children's ability to understand and infer the thoughts and feelings of others influences how they develop a unique view of the world. Examining developmental factors that impact young children's success in both social and cognitive domains has important implications for advancing our current knowledge of social cognition. The purpose of this…

It is well established that children lie in different social contexts for various purposes from the age of 2 years. Surprisingly, little is known about whether very young children will spontaneously lie for personal gain, how self-benefiting lies emerge, and what cognitive factors affect the emergence of self-benefiting lies. To bridge this gap in…

We investigated how the ability to deceive emerges in early childhood among a sample of young preschoolers (Mean age = 34.7 months). We did this via a 10-session microgenetic method that took place over a 10-day period. In each session, children played a zero-sum game against an adult to win treats. In the game, children hid the treats and had…

Self-regulation and social cognition flourish as children begin school and engage with a new social environment. At the same time, this novel setting provides more complex social situations that children must navigate, including understanding when others may be lying to them. Social cognition and self regulatory abilities, such as Theory of Mind…

This study examined young children's deception in a conflict situation. A puppet show was prepared involving a protagonist who went into hiding, an enemy who wanted to catch the protagonist, and a friend who was looking for the protagonist. In the no-conflict condition, the enemy asked the children about the location of the protagonist. In the…
