The Sally-Anne Test

[sassy]

I dont think this would be a clear test - as not all Autistic children/people are the same - our brains work differently. - it's a spectrum so even if 1 Autistic person fails does not mean every Autistic person will fail.
and Generally Autistic people struggle to communicate in certain ways too so again, some might succeed at this.
and I think it would also depend on how this task was being presented to the Autistic child as to whether or not they would understand what is being asked of them also.
