This week’s article takes a deep dive into something very closely related to body language, but that few people know anything about or understand: stimming. We will discuss what it is, why many disabled people engage in it, whether it is good or bad, and finally we will talk about applied behavioural analysis, a type of therapy which is used to minimise stimming behaviours in autistic children (and sometimes adults) and to make them behave in specific ways.
On a quick side note, I would like to point out that I heavily drew on the writings of Dr Arielle Silverman in this article, as well as information from several articles that I found online. Until I read Dr Silverman’s book, I wasn’t even aware that these behaviours were called stims, and I did quite a lot of research for the purposes of this article, as stims were something I didn’t ever give much thought.
So what is stimming? Stimming is a term used to describe a movement or behaviour that is meant to provide sensory stimulation. This can be anything from rocking one’s upper body, to pushing one’s eyes, to hand flapping, to rubbing or stroking specific types of objects. Other stims include hair pulling, rubbing or scratching the skin, walking on tiptoes or pacing, flicking or snapping fingers, bouncing, twirling, repeating specific words or phrases, blinking repetitively, swinging the head, staring at lights or rotating objects, or rearranging objects. Nondisabled society tends to have a very negative response to seeing disabled people stim.
Most of these kinds of stimming are probably most common in people on the autism spectrum, but people with other disabilities such as blindness also tend to stim. When it is a blind person stimming, the behaviours are sometimes referred to as blindisms.
When I was a little girl, I used to push at my eyes with my knuckles, or press them with my fingers. Due to how common this behaviour is in people who were born blind, it has been dubbed the “oculo-digital reflex”. Contrary to what people assumed, I did this not because it made me see sparks, or anything of the like. The best way I can describe it is that it felt comfortable and soothing, and I often did it unconsciously. To this day, I sometimes do it, but from a young age I was taught by my mother and my school teachers that I shouldn’t do it, so I have largely unlearned the habit. There was good reason behind them stopping me, in my opinion. They said it might damage the little sight that I have, and that it would cause my eyes to become sunken. This could already be seen in the eyes of many of my schoolmates. It is worth noting that it is something that happens gradually, and that it is also difficult to tell if eye poking causes sight loss or sunken eyes. Some eye diseases are degenerative, such as my own, and some cause changes in eye shape over time. Still, I am glad that I mostly stopped poking my eyes overall. I still stim though. I play with my fingers or nails (as you can see in this post’s featured image), especially when bored, excited or nervous. Sometimes I just do it unconsciously in conversation when I am totally relaxed though, and it doesn’t signify anything about my mood. I also have a little black cilicon cat wine glass marker that I carry with me everywhere. I put it on my glass, not to tell me which is my wine glass, but to play with. The texture is nice, and the cat reminds me of my own real black cat Riddle whom I hardly ever get to see anymore due to reasons I won’t go into here. I have other stims, but these are just two prominent examples.
Other behaviours noticeable in blind people I went to school with included rocking back and forth, swinging their heads, or chewing at their hair. These behaviours can also be seen in many people with autism. Unlike eye pushing, these behaviours are not harmful. They just look strange to sighted or neurotypical people.
The thing that most nondisabled people don’t understand though, is that it isn’t only disabled people who stim. Most nondisabled toddlers will jump, bounce, run and climb. These behaviours can be potentially dangerous if the toddler isn’t being supervised, but they are allowed and seen as normal. Some people tap or chew their pencils, bite their nails, play with their rings or bracelets, squeeze stress balls or play with small objects. Others twirl their hair around their fingers, jiggle their feet or legs, crack their joints or knuckles, and drum their fingers on surfaces.
Whilst some of these behaviours are criticised, they are still seen as completely normal, simply because they are very common behaviours that are engaged in by nondisabled people. Gesturing while talking, even if it’s over the phone, can also be considered to be a stim. However, it is merely seen as body language, a way in which people express themselves. You may recall from the previous article that I found it very strange when I was little. I just couldn’t understand why people felt the need to do so.
Is stimming good or bad? This is a complicated question. Stimming can be good, in that it provides needed sensory input, may release pent-up energy, may be physical expressions of people’s emotions, and may even lessen some types of unwanted sensory input. Autistic people use stimming as a form of comfort in order to manage anxiety.
However, some stimming (such as my eye pushing) can actually cause harm. Further examples include head banging, excessive scratching or rubbing at skin, hair pulling to the point where it falls or is yanked out (the psychological term for this is trichotillomania and is not always simply a stim), biting or punching, swallowing or sucking dangerous or poisonous items, and picking at sores or scabs.
Another situation in which stimming can be harmful is in cases where it forms part of someone’s obsessive-compulsive disorder (OCD), which is a disorder that involves someone fixating on an obsession which causes anxiety, and then engaging in a compulsive behaviour that is meant to reduce that anxiety, but just ends up feeding the obsession. For example, as part of my OCD, I very regularly wash my hands. I am over stimulated when my hands feel dirty or grimy, so I wash them to feel clean. This can get to the point where I wash my hands without them being dirty, because I just think they might be. This can lead to very dry and cracked skin, and in extreme cases, even bleeding. I have also been known to rearrange objects over and over, which takes a lot of time. Something else that I do that might be considered a stim, is to count grooves on objects, because I have an obsessive need to know the number of grooves. I count them, forget the number, and have to start all over again. Many people (such as one of my friends to whom I read this paragraph) might disagree with me that these count as stims. My friend’s logic is that stims are usually enjoyable to people, whereas OCD symptoms become highly frustrating to people who exhibit them. In my view, they count as stims though, because behaviours such as hand washing can initially provide much relief to someone with OCD, and are engaged in with the purpose of lowering anxiety levels.
In the cases mentioned above, addressing these behaviours is a positive thing, in my opinion. However, we need to ask ourselves if it is really necessary to fixate on stopping other stims that are not harmful to anyone. For example, rocking isn’t something that is harmful. It is just seen as negative, because it looks so strange to nondisabled people. Whilst I prefer not to rock, because rocking might make me appear unprofessional in a work setting, for example, others may not care about that, and might argue that society should adapt to the fact that different people have different physical mannerisms. Honestly, I think it should too. Society is exceedingly judgemental towards people who don’t fit the mould of what is considered “normal”.
Regardless of whether or not one sees stimming as good or bad, there are ways and means to address them. Firstly, it needs to be consensual. Forcing therapy on someone is never okay, unless that person is a serious danger to themselves or others. Secondly, it should never, ever be addressed through punishment, such as a parent slapping a child when they stim, or taking away their toys or other possessions. Most of the time, punishment doesn’t really work in addressing stims anyway. When I was younger, I personally asked for my hands to be lightly slapped by my mother when she would see me pushing my eyes, but that was my own choice, and the slaps never hurt.
Ways in which harmful or socially frowned-upon stims could be stopped or controlled in certain settings (if the stim is actually something that the individual wants to let go) could include finding an alternative way to stim which is harmless, subtle and socially acceptable. For example, an individual could discretely use a fidget object such as a stress ball. Wearing a reminder bracelet, or having a reminder word could also work. Blind children or adults who don’t necessarily know how their body language is being perceived could take acting or body language classes to learn about typical nonverbal communication. Rewards can also be used to motivate children to control or stop a certain stim, although it is worth noting that it might not be a sustainable solution. Also, as Dr Silverman points out, parents are not always present to make sure the child is not engaging in the specific behaviour. A child may be very aware of their parent’s gaze when they are expecting a reward, and thus be consciously trying not to stim. However, the child may unconsciously stim when their parents are not there, because they are not paying attention.
At this point, I would like to address a specific type of therapy that is the most prevalent for people with autism when trying to teach them to adapt “better” to society and the world around them. It is called applied behavioural analysis (ABA). Extensive research shows that this type of therapy is effective in instilling adaptive behaviours in autistic children and adults, but at worst, this type of therapy is actively cruel, even when used with the best intentions. This might not be easy for parents of neurodivergent children who believe in ABA to hear (because of course they don’t want to hurt their children) but it needs to be said.
There are many different variations of ABA. However, the therapy typically involves three steps:
- An instruction called an SD: This can be a verbal instruction given in a slightly louder voice than one would normally use, or it can involve presenting the autistic child with a picture or toy with which to interact.
- Response or prompt: This involves the child responding to the instruction, or the therapist giving a prompt if the child seems not to understand.
- Reinforcement or correction: If the child follows the instruction or responds in a way that is considered to be appropriate, they are praised and rewarded immediately to reinforce the action. If they do not follow the instruction, or respond in the “wrong” way, they are corrected. This can range from being told “no” in a neutral voice and being instructively told or shown the appropriate response, to pausing and leaving out the “no” before the repeat instruction and being told or shown the appropriate response, to the very extreme (and highly problematic) correction in the form of a punishment such as an electric shock.
These days, ABA therapists have moved away from punishing autistic children when they don’t comply with instructions, and focus strongly on reward. However, punishment is not the only thing with which anti-ABA advocates take issue. The main critique is that the focus of ABA is to make autistic children appear less autistic, or to act in accordance with what society considers to be “normal”. This is as opposed to trying to determine why the autistic child is acting in the way that they are. Advocates in the autistic community believe that the focus should be on teaching skills, such as assisting an autistic child who is silent to start talking and engaging with schoolmates, or assisting an older person with autism to be more organised, instead of the focus being on normalisation. For this kind of approach, therapists would need to take guidance from adults with autism. Autistic people need to be seen as clients, not patients, and they need to have a say in the things they want to address. Therapy should not be about changing or concealing who a person is. It is also necessary to consider that the same types of therapy may not work for all autistic people, such as in a case where the autistic child may understand what is being instructed or requested, but may not be able to immediately plan a response.
Also, ABA methodology can be cruel regardless of whether or not there is punishment. ABA therapists often grab the hands of autistic children and fold them in their laps, or regularly touch them in other ways. Many autistic people have an extreme aversion to being touched, and nobody should ever simply just be touched without consent in the first place. ABA therapists are known to force people with autism to make eye contact, which is something that is very uncomfortable for them. Prolonged eye contact can actually be uncomfortable to many people who are not on the spectrum, and this goes for touch as well.
Most importantly, autistic people feel that ABA does not place importance on the emotions and needs of the individual. Instead, the behaviours are all that count. If a child appears to be tired, overstimulated, or upset, this is regularly just ignored in favour of continuing to push them to follow instructions. Often, autistic children will comply, simply to get it over with. This does not mean they are comfortable or happy. This simply means that they are being taught to suppress their needs, and that their feelings don’t matter. Attempts to communicate things that are not in line with behaviours being demanded by the therapist are mostly just ignored. When autistic people are forced to engage with certain environments such as busy supermarkets, their ability to tolerate discomfort is not an indication that they are suddenly functioning “better”. In the moment, they might not experience a melt-down, but it is just being postponed. ABA demands a child’s attention, but refuses to give attention back when the child is trying to communicate something.
Another thing that is vital to understand, is that ABA sessions are not simply a couple of hours a week. It is recommended that young children between the ages of two and five go through forty hours of therapy a week. Is it any wonder the children become tired and upset? They are being put through forty hours a week of essentially being told that it is good and right for them to suppress their emotions, and that their ways of soothing themselves are wrong. ABA does not account for the fact that children are not taught to stand up for themselves or to self-advocate. Instead they are taught to never disobey or disagree.
Finally, teaching these things to children can be very dangerous. 70% of people with autistic spectrum disorder (ASD) have experienced sexual abuse by the time that they have finished high school. It is very possible that this is partially a result of the fact that they were taught as children to never object, say no, or refuse to follow orders.
In conclusion, stimming is not simply an activity such as doodling when a person is bored. For many people, it is a self-soothing behaviour that reduces stress and regulates emotions. Many also feel that the stims are a form of communication, because often, facial expressions are misinterpreted. Although I have pointed out some harmful stims in this article, I genuinely hope that I have been able to communicate that this is a much more complicated issue than one might initially think when seeing someone engaging in a behaviour that is considered strange by society, and that it is necessary to be extremely cognisant when it comes to trying to stop or control these behaviours in both children and adults.
I was only diagnosed with ASD this year as an adult. My stims are relatively inconspicuous (biting my lips and cheeks, scratching dirt out from under my nails, picking at acne, playing with my hair) so while I was a weird kid, on a linear scale from extremely boring to extremely weird, I was probably perceived as within a standard deviation of average. Although I could probably have benefitted from knowing about it and having access to resources at the time, the mere existence of ABA is one of the reasons I’m glad I flew under the radar as a kid in the 90s when ASD was still not that well defined and understood, and research around autism in adulthood was lacking.
Interestingly, some principles used in ABA (many of which are not exclusive to ABA) are valuable to know in the context of animal training. For example, positive reinforcement, which is the cornerstone of just about every ethical, ethology-based methodology. Punishment on the other hand has been consistently shown to work poorly in general across all species, which is further evidence against its use on humans.
Based on personal experience having trained dogs and horses, I surmise that punishment may work slightly less poorly on prey species as opposed to predators. Prey species have an extremely strong fear response that they depend on for survival, and an excellent memory when it comes to things that have scared them in the past, including associated precursor behaviours. A minor scare such as sudden movement or clapping of hands is more than enough to startle a horse into stopping a behaviour, in the moment.
However, even though an animal (regardless of species) can be well aware that a behaviour is undesirable by demonstrating anticipation of a reprimand after said behaviour, punishment can (and does) inadvertently reinforce the behaviour instead of discouraging it. If the trainer creates an inescapable negative environment, a fear response can turn from aversion (flight) into confrontation (fight) when running away (literally or as mental withdrawal) is no longer an option. This fosters an antagonistic relationship between trainer and trainee. From that point, the damage cannot be undone, the trainer may never be trusted again, and further punishment will only be met with resistance. At worst, this can result in serious injury or even death.
Instead, what works far better for eliminating problematic behaviours is substitution. For example, a puppy chewing on shoes should be given a chew toy in exchange, and not punished at all. Puppies need to chew for healthy dental development, and chewing remains a boredom and stress-relieving behaviour in adult dogs (yes, not just humans stim). The problem here was not the behaviour itself but rather the object thereof. Dogs do not innately know what they are or are not allowed to chew on. So it is up to the human to teach them, and keep inappropriate chewables (and non-chewables) out of the dog’s reach while they are still learning.
Substitution is also applicable to harmful stims, as exemplified in habit replacement. It is far easier to swap out one bad habit for another, less harmful one, than it is to eliminate it. As long as the subject consents to it, and/or the habit is causing harm. But even then, one has to weigh up the impact of replacing the stim, as opposed to doing nothing, to figure out what is in a subject’s best interest despite their wishes at the time. They may end up resenting the decision, or they may be grateful down the line. It’s difficult to be objective about these things without the benefit of hindsight.
Despite B. F. Skinner’s controversial views and methodologies, he was very much anti-punishment and had a strong interest in improving processes in mainstream school education towards positive reinforcement and the purposeful fostering of a genuine interest in learning. It’s a real shame his work on ABA was so flawed that it was and still is used to teach children to supress themselves for the sake of appearing “normal” at best, and to justify abuse at worst.
Again, a very insightful comment, Leeward!
Punishment certainly can reinforce a behaviour. Often, it makes one fixate on the behaviour in the first place. Thinking “I mustn’t do this, I mustn’t do this” keeps the “this” fresh in one’s mind, and to speak for myself, the more something sticks in my mind, the more likely I am to actually engage in it. That happens in my OCD.
I have also experienced first hand how replacement works better than simply stopping a bad habit. For example, I replaced smoking cigarettes gradually with using a vape, which whilst still not healthy, is reportedly much better for one than smoking cigarettes. At the very least, it doesn’t make one’s hair or clothes smell bad, stain one’s fingers or teeth, or even bug most people I’m around when I use the vape in front of them because it just doesn’t have a very noticeable scent.
Way cool! Some extremely valid points! I appreciate you penning this article and the rest of the website is extremely good.
