People with Autism Often Less Surprised by Unexpected
Further, investigators found that adults with autism were less surprised by unexpected images in a simple learning task than adults without autism. And, those who were the least surprised had the most pronounced symptoms.
The UCL study is published in Nature Neuroscience.
“We know from previous studies that people with autism often aren’t surprised by things that would surprise other people,” said lead author Dr. Rebecca Lawson (UCL Wellcome Trust Centre for Neuroimaging).
“Our results suggest that this may be because of differences in how people with autism build expectations. Our expectations bias our behavior in subtle ways, so being less susceptible to these effects may result in strengths as well as difficulties.”
Insistence on sameness and intolerance of change are part of the diagnostic criteria for autism, but there has been little research addressing how people with autism represent and respond to unexpected changes to their environment.
In this study, 24 adults with autism and 25 adults without autism completed a task that involved learning to expect to see different pictures on a computer screen after hearing either a high or low sound.
The researchers applied computational modeling to the data to characterize each person’s learning process. They found that adults with autism tend to overestimate how changeable the environment is, which reduces how much their prior expectations guide their behavior.
The adults with autism learned the task well enough overall, but showed differences in updating their expectations when the environment unexpectedly became more volatile.
The most notable incident this happened in my life was 9/11. I am always told to stop being so negative. But I am often surprised by people and social sitiuations.

Hmmm, this is definitely interesting, but I'm not so sure I understand what they're saying----or, that I agree with it.
Firstly, I'm thinking it's possible that the fact that we're so much more bothered, than NTs, by "normal" things happening in our environment (ie, sounds, smells, etc.), that it makes us more likely to, however consciously, condition ourselves against them----as in, not allowing ourselves to be surprised, because being caught off-guard can often bring us much, MUCH more problems, than whatever it was, that happened, in the FIRST place.
Also, it never ceases to amaze me, how often studies, like this, seem to ONLY consider what's on the surface, instead of considering ALL of the possible factors, that could play-into someone's response, to whatever----for instance, was the age, culture, "usual" environment, etc., taken into consideration, when these people were tested? In regard to "usual environment", would a city dweller, respond the same as a suburban dweller----or, the same as someone from a farm community (rural)? Would a 6-year-old, respond the same as a 16-year-old----or, a 36-year-old----or, a 60-year-old? In regard to culture: Would a Latino-American respond the same as an African-American, or a European-American----or, would any of these groups respond the same, as a fairly newly-arrived immigrant?
Also, what about the way someone is raised----for instance, if they were raised by a "helicopter mother", as opposed to a NON-helicopter mother----couldn't that have something to do with the way they react, to something?
Two personal examples, of this, includes: My mother used to fuss at me, all-the-time, for being startled, by things----she said it was stupid for me, to continue to allow myself to be affected, by so many things; so, because I didn't wanna continue to get fussed-at, so much, I worked really hard to condition myself to NOT be so easily affected, by things (surprised / startled / whatever).
Another example, is: More-than-once, I've gotten off the bus, and walked past a dead body----or, been ON a bus, when a knife fight, broke-out----and, had no reaction to any of these things. Was this because I'm autistic? Would a person from a farm community react, the same? Would an NT react, similarly? OR, is it just that I'm so used to SO MANY things happening, during the course of, say, a few months, that I have the attitude, of "What's one MORE thing"?
