Out of the Autistic Closet: the Psy Celebrates Autism Awareness Month

Autism is a disorder about prediction in general and predicting social outcomes in particular. Without your knowing it, you predict the outcome of every social interaction you have. You have a sense of how the other people interacting with you will react. Those predictions guide your next behavior. Occasionally, you have doubt, uncertainty, choices, but usually you have a confidence in what your instinct is telling you to do.

Autistic people don’t have that. Don’t get me wrong, auties have an automatic pilot when it comes to social interactions. It’s just that you’re wrong much of the time. The autie is not behaving in a way that others predict, which leaves people a little or a lot annoyed depending on where they land on the ambiguity tolerance scale.

It is the accuracy or inaccuracy of those predictions and the behavior the prediction guides which causes social anxiety in auties. Eventually, you figure out that people are reacting negatively that somehow you’ve said or done something wrong, but that something wrong seems arbitrary and unjust to you. You just don’t get that social perception.

Learning Social Interaction

Socially Awkward Social Distancing: Autism in the Era of #COVID19

Social interaction is learned. The proper behavior in a specific situation is learned through observation and interaction. How close do you stand to someone when you’re talking? It varies by culture, but most people in those cultures work it out and follow the same rule. How loudly do you talk? How much eye contact do you make? When do you make eye contact? How do you know when it is your turn to talk? All of these little rules guide your behavior without your being consciously aware of them.

How does all of that work then? How do we learn these social rules and what happens when we accurately and inaccurately predict social situations?

A lot of this type of learning takes place in the liking-wanting system of the brain, sometimes called the reward circuit, even though it is a less accurate description of what is happening. Either way, though, it is a dopamine-based system. We write about the liking-wanting system a lot because it is so integral to our behavior.

The Dopamine of Politics: The Reward and Liking Systems

You know you’ve activated the liking-wanting system when you want to do just one more of something, like read one more blog post by your favorite blogger even though you know you’ve spent too much time on Ye Olde Blogge already, but you just can’t help yourself.

It’s there to keep you doing things that are good for you. That you like. That are helpful. Like accurately predicting the outcome of a social interaction. You predict accurately, you say the right thing, you make the right gesture, you get tacit approval from the person you’re interacting with, and dopamine is released into the liking-wanting system making it more likely that you’ll do the same or similar things the next time this situation occurs.

For auties, though, we get a flood of stress related chemicals released into our nervous systems when social situations come up. Everyone does to some degree, but in autism, it is a deluge. You are drowning in them. And, what does stress do? It makes it impossible to think! Your associative system is now offline. Consequently, even if you’ve been in a similar situation before, you don’t unconsciously access that memory like most people do, so it cannot guide you.

Even if something good comes out of the social interaction, auties have fewer opportunities to reinforce them because of the stress. The wanting and liking systems help you encode the events that triggered them in your memory so you are now hardwired to stimulate dopamine should something come even close to replicating them again. Auties don’t do that. Stress prevents it from happening.

Instead, they encode a warning to avoid the situation that triggered the high level of anxious distress. Everyone does. It’s your brain’s way of keeping you safe.

The Underactive Parasympathetic Nervous System

Autism Awareness Month, 2019: The Dopamine of Pathological Demand Avoidance

This suggests two things to me. First, that auties are predisposed to activating their sympathetic nervous system. That’s the system that controls flight or fight. It actually is engaged all the time. In neurotypical people, the parasympathetic nervous system keeps it in check. The parasympathetic system in auties is “weaker,” less likely to engage or manage the sympathetic system, especially around social situations.

In PDA, the sympathetic system favors the flight mode of panicked coping. Freezing like a deer in headlights. Chemically, their motor cortex has disengaged from their bodies. Their brains are no longer really thinking rationally. Everything is held in suspended animation until the danger passes only the danger is the little cutie you’ve had your eye on saying hi. Or, the barista being short with you because you’ve fumbled your order on a busy day at the coffee shop. Or, finding that you’ve got a fifty and ten ones to pay an eight dollar tab with and the prospect of giving the cashierest either seems like it will inconvenience them and they’ll be mad at you. The fifty will mean they have to produce too much change, the eight ones will mean you’ll take too long counting them out.

Looking at it while sitting at your kitchen table perusing your favorite blog makes it seem ridiculous, but as it happens, it results in freezing up. The inability to speak or move and feeling deep shame and embarrassment and self loathing.

For the auties their is always an audience inside their head knowing every little thing that is happening and the reasons why and the audience is composed entirely of Statlers and Waldorfs. Everyone in there is a critic without mercy.

Because of the underactive parasympathetic nervous system, the sympathetic nervous system runs wild and dominates the day-to-day moment-to-moment life of the autie from eight o’clock day one. The liking and wanting system is underdeveloped through under use. It becomes difficult if not impossible for the autie to learn social cues and social norms, stunting the development of normal social perceptions much like Hubel and Wiesel’s kittens couldn’t develop their visual cortices after he had sewn their eyes shut and were blind when he opened them again.

The only relief from the stress and anxiety comes from delving into a rich inner world and avoiding the confusing hurtful outer one. Only, the confusing hurtful outer one keeps intruding and demanding attention and action. It makes for a difficult life until you can find some way to make peace with it.
