Researchers from Frontiers in Child and Adolescent Psychiatry studied 123 children aged 6 to 11 years: 42 with autism (Level 1), 43 with ADHD, and 38 developing typically. They tested executive functions—the brain skills that help us plan, focus, and switch between tasks—and social cognition, which is our ability to understand what others are thinking and feeling.
The study revealed that while both conditions create social and learning struggles, the root causes are fundamentally different. This distinction matters because it changes how you should support your child.
ADHD: The Brakes Problem
Children with ADHD primarily struggle with inhibition and attention control. Think of it as weak brakes in their brain—they find it hard to stop impulsive actions or filter out distractions. When they interrupt in class, blurt things out, or miss social cues, it's usually because they're not controlling their impulses or paying close attention, not because they don't understand social situations.
Autism Level 1: The Perspective Problem
Children with autism Level 1 show stronger challenges with cognitive flexibility—the ability to switch between different ways of thinking—and understanding what others are thinking (called "theory of mind"). Their social difficulties come from genuinely struggling to figure out what's happening in someone else's mind, rather than from impulsivity. They find it harder to adapt their thinking when situations change.
One Strategy Won't Fit Both
The key finding: in children with ADHD, social skills improve when you strengthen their attention and impulse control. But in children with autism, social skills need to be taught more directly through explicit instruction about thinking patterns and how to read social situations. In Singapore's achievement-focused environment, both conditions can be misunderstood. A child with ADHD who can't sit still might be labeled "naughty" when they need help with impulse control. A child with autism who struggles in group work might need coaching on reading social situations, not discipline.
This research supports proper assessment beyond a simple diagnosis. Knowing whether your child has ADHD or autism is a roadmap for exactly the kind of help they need, so schools and parents can use targeted strategies rather than treating all social or learning struggles the same way.
How to Support Your Child
- For ADHD: focus on strengthening attention and impulse control through structured routines and clear rewards for staying focused.
- For autism: teach social understanding directly by explaining social rules, perspectives, and what others might be thinking in specific situations.
- Request an assessment that tests both executive functions and social cognition, not just behaviour observation, to guide the right approach.
