They found that children who did not have autism took a longer sniff for roses and a shorter one for rotten fish, and the difference in breathing happened quickly, within one-third of second of being exposed to the scent.

In contrast, children with autism did not change their breathing in response to the different aromas.

Seems accurate.
As a toddler I was apparently hyposensitive to smells since I could play in garbage or paint using my own poo...

Not me; I have heightened sensitivity to smell.

I have lots of allergies & sinus problems so I'm very sensitive to certain smells.

I actually like smelling things

I dunno if it's got anything to do with ASD, but I'm known for have a odd sense of smell, some things like the smell of tuna don't bother me at all, while say ketchup will make me have convulsions.

Supposedly thinking that something is a "good" smell or a "bad" smell is something that is socialized into children. That is why toddlers are not bothered by the smell of a dirty diaper. They can smell it the same as an adult, but they don't think of it as a "bad" smell. So it makes sense that autistic kids might not necessarily have the same associations of a rose as a "good" smell and a rotten fish as a "bad" smell, hence no difference in how long they sniffed.

I would definitely inhale the scent of roses a lot longer than rotten fish! As a kid I was obsessed with getting to smell a rose but they seemed so rare when I was a kid. The non-cultivated wild rose bushes that grew thick around my neighborhood didn't count. But I hated the smell of fish. And the taste. And the skin. And the tiny bones. And since my dad was a fisherman that was a bit of a problem. There used to be a fish plant not far from my home and sometimes I wanted to go to the old general store or look at the boats that were down there but the reek of fish was so bad I once thought about putting tape over my nostrils so I couldn't smell it.

Hmm; I've always loved to sniff nice smells like roses, and been repulsed by what most would class as nasty smells. I've been pretty conventional about smells as far back as I can recall.
