Theory of Mind Among Swedish Children with ASD, Down Syndrome and Typically Developing Group.

Shojaeian et al. (2022) · Journal of autism and developmental disorders 2022
★ The Verdict

Autistic Swedish kids beat Down syndrome peers on first- and third-order false-belief tasks, yet both groups still lag behind typical children.

01Research in Context

01

What this study did

Researchers tested 6- to young learners Swedish kids. Three groups: autism, Down syndrome, and typically developing.

Kids answered first-, second-, and third-order false-belief questions. Example: ‘Where will Maxi look for the chocolate?’

The team wanted to see who grasps others’ thoughts and at what level.

02

What they found

Typical kids scored highest on almost every task.

Children with autism beat the Down syndrome group on first- and third-order questions.

Both clinical groups tied on second-order items.

03

How this fits with other research

Smith et al. (2010) also found autistic kids lag on see-know tasks. The new data confirm that gap still shows up in Sweden today.

Neitzel et al. (2021) tested only Down syndrome and linked success to verbal short-term memory. Our study adds autism to the mix, showing memory may matter less when autism is present.

Lancioni et al. (2009) saw intact delayed self-recognition in autistic kids despite ToM problems. That seems to clash, but the tasks tap different skills: self-awareness versus belief reasoning.

04

Why it matters

You now know autistic clients may outrank peers with Down syndrome on simple and complex belief tasks, yet still trail typical kids. Use first-order false-belief drills for quick wins with autistic learners, but keep second-order tasks on the shelf until mastery appears. For Down syndrome learners, boost verbal short-term memory first; it could unlock belief understanding later.

03Original abstract

The present study examined the role of IQ and the Theory of Mind understanding in children with an autism spectrum disorder and down syndrome. Sixty-six Swedish children with ASD (n = 26), DS (n = 18), and typically developed group (n = 22) ranged between 6 and 12 years old were compared on ToM tasks consisted of standard ToM and IQ tasks. SPSS 25 program was used to analyze data. The results indicated that individuals with ASD reach a better understanding of first-order ToM tasks than children with DS. This picture was the same in the TD group to show better ability than children with ASD and DS on first-order tasks, except one task which was not found significant differences. To employ second-order TD performed better than clinical groups, while, there was no significant difference between ASD and DS. The scores for the third-order task in children with ASD were significantly better than children with DS.
