The Astonishing Age When Little Aussies Start Telling Porky Pies
It turns out our youngest Aussies are developing a talent for the sly and the cunning far earlier than many might expect. New research has shed light on just how early children begin to understand and employ deceptive behaviours, with some demonstrating these skills as young as eight months old. This fascinating insight into child development suggests that the seeds of becoming a “cunning little lair,” as one researcher put it, are sown remarkably early in life.
The study, published in the esteemed journal Cognitive Development, surveyed parents of over 750 children across the United States, the United Kingdom, Canada, and crucially for us, Australia. The children involved were up to 47 months old, meaning some were nearing their fourth birthday. The findings paint a compelling picture of evolving cognitive abilities and social understanding in toddlers.
A Timeline of Toddler Trickery:
- Early Stirrings (8-10 months): Astonishingly, some parents reported their child first grasping the concept of deception as early as eight months. By ten months, a quarter of the children in the study had begun to understand that certain actions or statements could mislead others.
- Growing Comprehension (16 months): The halfway mark was reached by 16 months, with half of the children demonstrating an understanding of deception. This indicates a significant cognitive leap occurring in the first year of life.
- Skillful Fibbers Emerge (3 years onwards): As children approach their third birthday, their ability to engage in deceptive practices becomes noticeably more sophisticated. They transition from simple tactics to more complex strategies.
Elena Hoicka, a professor of education at the University of Bristol and the lead author of the study, expressed her amazement at the findings. “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’,” she stated. Drawing on her own experience as a mother of three, Hoicka added a relatable touch: “As a mother of three children myself, I can certainly vouch for how artful and wily they can be. Hiding under the table or in the bathroom to eat sweets or chocolate is their common ploy.”
The researchers identified a remarkable 16 distinct types of deception that children employ, ranging from simple denials to more elaborate fabrications.
The Evolution of Deceptive Tactics:
From around the age of two, children’s deceptive behaviours tend to be more action-oriented or require minimal verbalisation. These early tactics often involve:
- Pretending Not to Hear: A classic move is feigning ignorance when asked to perform a chore, such as tidying up.
- Concealment: Hiding objects from others is another common strategy to avoid consequences or keep something desirable to themselves.
- Denial: This can be as simple as denying an action, like shaking one’s head to say “no” when asked if they’ve eaten a forbidden treat, even if they have.
- Secret Activities: Engaging in forbidden activities when they believe they are unobserved, such as peeking into a bag they were explicitly told not to open.
- Making Excuses: Inventing reasons to avoid tasks, like claiming to need the toilet when it’s time to clean up.
As children grow older, their capacity for more intricate forms of deception expands significantly. This is where we see a move towards more complex cognitive strategies:
- Exaggeration: Overstating facts, such as claiming to have eaten all their vegetables when only a small portion was consumed.
- Understatement: The opposite of exaggeration, downplaying the extent of something.
- Complete Fabrication: Crafting entirely false narratives, like blaming a mythical creature for a transgression, such as a “ghost ate the chocolate.”
- Feigned Ignorance: Pretending not to know, see, or understand something to avoid responsibility.
- Withholding Information: A more sophisticated tactic involves providing partially true information while omitting crucial details. For example, accurately reporting that a sibling hit them, but leaving out the fact that they provoked the sibling first.
- Distraction: Three-year-olds, in particular, begin to master the art of diversion. They might shout “Look over there!” to divert attention while they carry out an unauthorised action.
These findings highlight the rapid development of theory of mind – the ability to attribute mental states, beliefs, intents, desires, and knowledge to oneself and to others – in young children. Understanding that others have different thoughts and perspectives is a crucial step in developing social skills, and deception, while often viewed negatively, is a complex manifestation of this burgeoning understanding. It underscores the incredible cognitive journey our children undertake in their earliest years.
