The ability to deceive, once thought to be a complex skill developing much later in childhood, may emerge surprisingly early. Fresh research indicates that some infants commence to grasp the concept of deception as early as 10 months old, with that number rising significantly by 17 months. This challenges previous understandings of cognitive development and suggests that the foundations of “little white lies” are laid much earlier than previously believed.
The study, led by researchers at the University of Bristol and published in Cognitive Development, offers a new perspective on how children understand and utilize deception. Researchers found that by the age of three, children are not only more adept at deception but also demonstrate increased creativity and frequency in their fabrications. This early understanding of misleading others has implications for how we view the development of social intelligence and theory of mind in infants.
The research team analyzed data collected from parents of over 750 children aged between 0 and 47 months, across the UK, US, Australia, and Canada. Parents were asked a series of questions about their child’s deceptive behaviors. The findings revealed that approximately a quarter of children exhibited an understanding of deception by 10 months, a figure that climbed to half by 17 months. Some parents even reported observing early signs of deception as early as 8 months old, according to reports from Chosun.com.
“It was fascinating to uncover how children’s understanding and usage of deception evolves from a surprisingly young age and builds in their first years so they become quite adept and cunning ‘little liars’,” said Elena Hoicka, Professor of Education at the University of Bristol and lead author of the study. Hoicka explained that previous research often positioned deception as a sophisticated skill requiring advanced language abilities and a well-developed understanding of others’ perspectives. However, by drawing parallels to deceptive behaviors observed in animals – including chimpanzees, capuchin monkeys, antelopes, and birds – the researchers were able to identify earlier, more rudimentary forms of deception in young children.
The types of deceptive behaviors observed in these young children are often subtle. Parents reported instances of infants pretending not to hear instructions, concealing toys, or surreptitiously consuming forbidden treats when they believed they weren’t being observed. As children grow, these behaviors become more elaborate, potentially evolving into more complex fabrications, such as claiming a fictional character consumed a forbidden snack – “a ghost ate the chocolate,” as noted in The Guardian.
This research builds on a growing body of work exploring the cognitive abilities of infants. The study’s findings suggest that the capacity for deception isn’t solely reliant on advanced cognitive skills, but rather emerges as a natural part of social and emotional development. Professor Jennifer Saul, an expert in the philosophy of deception at the University of Waterloo, Canada, and co-author of the research, contributed to this understanding.
Hoicka, a mother of three, also shared personal observations, noting that her own children demonstrated “artful and wily” behaviors, such as hiding under tables or in bathrooms to enjoy sweets in secret, as highlighted in a Newswise report. This anecdotal evidence reinforces the study’s findings and underscores the prevalence of early deceptive behaviors.
Even as the study provides valuable insights into the development of deception, it’s important to note that it relies on parental reports, which are subject to interpretation and recall bias. Further research, utilizing direct observation of infant behavior, will be crucial to confirm and expand upon these findings.
Looking ahead, researchers plan to investigate the neurological underpinnings of deception in infants, exploring which brain regions are activated during deceptive acts. Understanding the neural mechanisms involved could provide further insights into the cognitive processes that drive this complex behavior. Continued investigation into the development of deception will undoubtedly refine our understanding of early childhood cognition and social development.
