It’s no so much stacking that’s a notable symptom, it’s collecting, arranging, sorting and displaying, often without playing with the toys as intended. Instead the focus is more on neatly sorting by color / shape / size etc. and sometimes preferring to keep them in that configuration over playing with them.
This is similar to the tendency for some autistics to focus on the part of a toy, like spinning the wheels on a toy truck, instead of playing with the truck doing truck things.
While these are commonly associated with autism, these two examples are neither necessary or sufficient symptoms to diagnose autism. Meaning that you can see this symptom in an allistic (not autistic) person and it does not mean they have autism and you can have autism and not have these symptoms.
One thing common to many autistic people is ground up processing. Their minds do incredibly well with details (the spinning truck wheel, the defining characteristics of the toys they sort) but sometimes don’t see “the big picture” as easily. It can be an incredible strength in many ways, especially when embraced and harnessed instead of shamed and “corrected.”







Thanks for the additional detail here! I knew I was making a broad generalization with “ground up” and don’t mean to imply that if you start with details (ground) you never make it to the big picture. As you said, more data and examples are necessary and while the overarching structure can eventually be seen, autistics are less like to wave away outliers as quickly as neurotypicals.
Still, I think it’s been well documented that in general autistics much more likely to utilize inductive reasoning whereas neurotypicals rely more on deductive reasoning. Both have strengths and downsides and work best in combination.
It’s almost as if we need each other and should cherish the differences that make us better together! In my experience, that means NTs need to adjust more to autistics because autistic people are constantly adjusting to a society that overvalues NTs.
