What is stimming?

edit

It is possible that some people who stim find great pleasure in their own stims, and little or no pleasure in others, and so they see other people's stims as not stims at all, unless they take the time to think and understand how autistics differ so much even from each other, and how autistics as a group differ from other people with stims. I was never really like this myself because I was able to read literature about autism at an early age, but it may have made my definition of stimming too broad rather than too narrow, as my first instinct when seeing a video such as this is that the animal is stimming, while it occurred to me a few seconds later that perhaps the animal just had very itchy skin.

Punding is called stimming by some, and this is the page that has the famous sweetiepie photo in the lede.

Many stims involve tactile sensation, seemingly with a lot of focus on the hands and mouth, but spinning in circles and rocking (possibly also headbanging) do not involve touch. However it is possible that rocking and headbanging are not stims at all.

Given that I see a clear trend towards expanding the definition of stimming, I won't distinguish between the various types.

Why do so many stims involve both the hands and an external stimulus? Why do stimmers typically not flap their hands in the dark (or do they? I can only say I dont)?

80% of autistic subjects in a survey find stimming enjoyable.[1]

why the hands?

edit

the hands and mouth combined have more tactile sensory neurons than the rest of the body combined, it seems, and much of what is left is on the face. i remember reading that some profoundly autistic children examine objects with the fingers and mouth only despite having normal vision. it isnt clear to me if these people are unable to process visual stimuli or if they simply find them less interesting. (There is a small chance that the question was added in as a "catch" to make sure that parents arent just selecting the most odd-sounding response possible, as some employment questionnaires do.)

sensory deprivation

edit

Some people enjoy sensory deprivation, which seems to be the opposite of stimming. Yet the common explanation is that people stim to get away from sensory overload. So which is it? I can see how focusing one's mind on a single stimulation might block out others, but one would think that autistics (and others) would seek total sensory deprivation if that was really the goal of stimming. I'm confused and I still wonder if the entire neuropsych industry is wrong about this.

Photosensitive epilepsy#Television

Some people with PSE, especially children, may exhibit an uncontrollable fascination with television images that trigger seizures, to such an extent that it may be necessary to physically keep them away from television sets. Some people (particularly those with cognitive impairments, although most people with PSE have no such impairments) self-induce seizures by waving their fingers in front of their eyes in front of bright light or by other means.


Photosensitive epilepsy#Fluorescent lighting

When functioning correctly, mains-powered fluorescent lighting has a flicker rate sufficiently high (twice the mains frequency, typically 100 Hz or 120 Hz) to reduce the occurrence of problems. However, a faulty fluorescent lamp can flicker at a much lower rate and trigger seizures.[medical citation needed] Newer high-efficiency compact fluorescent lamps (CFL) with electronic ballast circuits operate at much higher frequencies (10–20 kHz) not normally perceivable by the human eye, though defective lights can still cause problems.

Hand-washing

edit
 
This is me.

I was addicted to washing my hands with cold water when I was young, and would stand at the sink for a very long time if my parents allowed it. I am sure my hands must have been numb after just a few minutes in the cold water, and it's most likely that that feeling of numbness was, oddly enough, the very reason I was so entertained by it. I don't do this today; I've played in the rain a few times recently but I think what I like is more the wind than the water.

I didn't consciously name myself after this habit, and I didn't even remember it until I recently came across some old baby photos, but I've come to suspect the memory was lurking in my subconscience all this time. Despite having lost the memories, I know I am not exaggerating this or mis-interpreting the baby photos to make myself seem more interesting. And the two photos are far enough apart in time (I can tell by how tall I was) that I know my hand-washing habit lasted quite a long time. More photos may exist, because I know my mother made a collage of just my hand-washing habit, but some of the photos might have been just pictures of the sink.

I don't remember any particular event that made me lose interest in hand-washing. It's possible I found even more pleasure in other things, or it's possible that my parents finally ran out of patience and told me I wasn't allowed to wash my hands anymore. It may be that the pleasure faded with time just as other childhood pleasures have.

My username

edit

If my theory that I've retained a subconscious love of hand-washing is true, then I did not really name myself after this video game, as I'd long assumed. (One reason I'm unsure is that I don't always choose usernames at one precise moment or for one particular reason; I first used the name Soap in 2000 or 2001, but since then I've picked it up and dropped it several times.) It may also be that my hand-washing habit led me to focus on the soap in the game and not the other elements. However, if this is true, it was all subconscious, because I was done with the hand-washing habit by the time I was five years old at the latest.

Bath toys

edit

I was also addicted to holding foam alphabet bath toys in my hands throughout my childhood. I don't remember how this addiction got started, or whether it overlapped with my hand-washing habit. I do believe there was a phase in which I played with toys in the sink, but I don't know what toys they were. I rarely played with my bath toys in the tub, and didn't really think of them as bath toys at the time. As late as age 10 I was playing with them openly, even leaving them out on my bed when my best friend visited, with no explanation. Only years later did I become embarrassed, and only later still did I feel guilty for my habit. In my late teen years I tricked my mother into bringing me to a shopping mall so that I could sneak home with a new alphabet. I hid the toys from my parents from that point on, only acknowledging that I still played with them one morning in my early 30s (and only because I, even then, considered it more shameful than alcohol). I am glad that I held onto the habit for so long, as I grew taller, because it means the toys today in my adult hands still feel the same as they did when I had a much stronger habit. (Whereas if I had given up the toys when I was smaller, I might have found later on that they felt too small.)

The bath toys today are mostly made by Munchkin and manufactured in China. Most of the competitors are lookalike products with swapped colors, some of which might come from the same factory. However one alphabet I have says that it was manufactured by Sleeping Partners in Binh Duong, Vietnam. This is the same holding company that owns Tadpoles, which makes similar foam products such as floor mats. Others, such as Little Tikes, make their own letters where the shapes are also different. All of these products are made of EVA foam today, which is probably the best material for holding water and then drying out later on. When I was young I remember a competing product with a much squishier foam, which I was equally fond of at the time, but which I now suspect would have had trouble drying out after use in the tub (by this time I had already moved on from playing with the toys in the tub, assuming I ever had done so in the first place).

The lack of an article for bath toys is something I've occasionally thought about correcting, but the one time I started on a draft I realized there wasn't much I could write about. As I've implied above, I'm mostly active at Wiktionary now and I doubt I'll get back to the bath toys article here anytime soon. There is also a potentially problematic restriction against uploading pictures of toys, and while I think the foam alphabet bath toys would be exempt from that restriction, an article about foam alphabet bath toys isn't a very good article about bath toys overall.

Timing

edit

I dont know when I first started playing with bath toys. My mother claims I started out playing with them the way other kids did. I know I liked refrigerator magnets too, which may have been easier for me to hold in my hands when i was very young. But I note that the foam alphabet bath toys are intended for very young children.

Summary

edit

Both of these habits involved my hands. Until just now (Jun 2023), I had always thought of my odd childhood habits as being water-related. But I preferred to play with the bath toys outside the tub, and I don't remember any particular fondness for baths or playing in the rain, so it seems that whatever gave me pleasure only worked through my hands. I've lost the pleasure of washing my hands now as an adult, though it's possible I'm still getting some very weak pleasure that I just don't recognize because I've never been without it. I still occasionally play with alphabet bath toys, and might have the world's largest collection outside a warehouse, but it is no longer an addiction.

I am glad for this habit, as it is much cheaper than many other pleasurable things.

alcohol

edit

It did not occur to me to try drinking alcohol until my early thirties. This may have been partly due to stubbornness on my part, and a wanting to be different, such that I couldn't respect myself if I were to develop a normal habit like drinking. When I did start drinking, I needed to do it my own way. I preferred to mix red wine with red raspberry icecream, which I called a Pink Cow (because it did the opposite of what Red Bull does). I've taken breaks from the bottle (the longest break since I started drinking being 2½ years) but I consider myself to be a heavy drinker since I don't plan to give up the habit completely unless health or some other situation forces me to. As much as it hurts to admit it, I get more pleasure from alcohol today than from bath toys or hand-washing, and continue to drink despite obvious negative consequences, whereas playing with bath toys would bring no such consequences. This is why alcohol now embarrasses me but my childhood habits do not.

Some symptoms I get after drinking are not mentioned on the hangover page, such as visual hallucinations and muscle spasms. These are new symptoms for me too.

Hand sanitizer bottles

edit

I also collect hand sanitizer bottles, but only if they're rectangular. More on this later. I think these unite hand-washing with the feeling of holding something in my hands. My love of alcohol is just a coincidence, I think.

Low-alcohol activities

edit

I've done some stereotypical stims with low BAC, such as playing in front of a blinking traffic light, and playing for 2h40m in a sprinkler during a power outage. I will make no apologies for this, though it still puzzles me why I cant get the same pleasure from my shower.

The shower

edit

It's possible I can't enjoy my shower because I feel trapped. Both physically (moving around is fun), and with the mild but ever-present fear of a power outage.

other info

echolalia

edit

is there any relation between echolalia and stimming? most likely not.

we say Children often first babble syllables and eventually words they hear. For example, a baby may often hear the word "bottle" in various sentences. The baby first repeats with only syllables such as "baba" but as their language skills progress the child will eventually be able to say the word "bottle". and this is almost certainly a mistake.

It's possible my first words were echolalia, since my mother claims I was speaking at 7 months, but that my first word was whassat ... at that age I'm pretty sure I didn't understand what I was saying and must have just liked the sound of it. And I admit I'm skeptical of being able to produce an S sound at that age, too.

Scratchpad

edit

Small children may be more likely to engage in stims, and break the habit at an early age.

Reddit's staple man may have been punding or something else.

What hormone, if there is one, is common to all stims? Is it dopamine?

the photos

edit

Although the photo quality is poor since it's so old, i've just now noticed that the picture of me at [1] probably shows me playing with a full sink of water, since my left hand isnt fully visible, and since i probably couldnt reach the faucet at that age, someone (most likely my mother) must have filled the sink for me first. therefore at this age i wasnt yet sneaking up to the sink, and the expression on my face might be something like "what? already? i just got started". This picture is forty years old and i wouldnt trust even my mother to remember the situation at this point. Since this was the kitchen (though it looks like a bathroom, I know it isnt), it's also possible that my mother simply needed to use the sink herself for its normal purpose, but that to me all I could think of was discipline.

office supplies

edit

reinforcements and those colored shiny stars. i loved these when i was nine years old. I have a memory that may well be false of my teacher driving me to a store to buy the colored stars. But that makes no sense

10:09, 27 July 2024 (UTC) coming back to this, im pretty sure the memory is true, since i can't have a false memory of a store i've never been in. there's a small chance it was my mother who drove me there, but i can't accept that i'd confuse my mother for a teacher at such a young age. The store has long since closed down but i've confirmed it was near the school.

urge to play

edit

Ten years old was the last time I remember a physical urge to play, while I was sitting in class, as opposed to the more common feeling among adults and older children of simply being bored by the lesson. It was a very specific desire to get home and play with my bath toys, and nothing else would have satisfied me at the time, not even recess which was probably less than an hour away. I remember being bored in class at other times (though not often) and that was a very distinct feeling, even though I felt the same frustration at not being able to leave the classroom.

I remember playing with the numbers on the signs at my first job, though only very briefly, as i had little time to myself there.

I think my roommate may have seen me stimming with cards ("Wyoming"). I remember being reluctant to attend college specifically because I would need to give up my stimming habit, but then changed my mind after realizing I could do it in the woods when i first arrived and then wean myself off of it while i trained myself to study like the other students. All of these thoughts were unrealistic and I didnt know what dormitory life would be like.

I was nearly an adult at this time, so I wonder why the urge to stim was still so strong. It's possible that our brains, even in late adolescence, still have childhood pleasure pathways open that close shortly afterwards. (And not just for autistics .... think about video games and loud music. I even remember seeing an apartment rental ad that specifically stated I had to be 25 or older. It wasn't explained, but I knew that it was about loud music and not something related to jobs or income.) Even if the above is true, though, I suspect one reason I stimmed so much in adolescence was that I didn't have reliable Internet access, nor a car to drive, so there wasn't a lot else for me to do.

side issue

edit

I've said several times to others in conversation that while many adults are nostalgic for childhood, actually re-living it would be a prison sentence, as most of us would throw a fit on the first day back when we realize we're not allowed to control where we go, and (depending on what age we return to) might not even be allowed to leave the house. Why is it, then, that even the best off among us are not traumatized by our childhoods? I believe our brains change so dramatically as we age that what pleased us then will not please us now, and that even adults who greatly enjoy re-living childhood experiences with their own offspring would not actually want to re-live the experiences as actual children. I think also that our brains change so fast that there are even great differences between, for example, three-year-olds and six-year-olds.

Many of us remember happy childhood experiences at places such as theme parks. But if we actually re-lived our childhoods, we would not be able to visit those places at will. Neither do we get nearly as much pleasure from visiting such places as adults. Those few people who would enjoy reliving their childhood might be those same few who prefer routine over pleasure, perhaps because it makes them feel safe. Yet if we had adult minds I suspect we would not feel safe either.

other thoughts about bath toys

edit
00:20, 7 November 2023 (UTC)

because of increasing health problems, i've had to cut back on drinking and might need to stop altogether. i've noticed recently that i have the urge to play with the bath toys in a way i havent felt for quite some time, and i think it is a physical urge, not an emotional one.

these days

edit
18:23, 6 July 2024 (UTC)

it's possible i've been feeling the physical urge to play for the first time since i was 10 years old. i'm not claiming this is a good thing, but it's certainly not the worst habit i could have. lately on phone calls i've been eager to get off the phone as quickly as possible so i can go back to my stim toys. i was never like this with social media or other traditional habits so i think this is a different emotion. some more thoughts (Jul 7)....

  • i almost certainly did have the physiucal urge as asn adult, e.g. in college, but i didnt recognize it at the time because i hadnt yet been forced to withdraw from them (i obv couldnt bring bath toys to the dormitory, so i used notecards)
  • so instead what i may be feeling is the combination of the physical and emotional urges at the same time.

i think stimming for me is comparable to playing video games or listening to music, and that these are also stims for me, that just happen to be shared among NTs. i lack certain other stims like rocking and headbanging, and yet these both have parallels in NT society (rocking chairs and headbanging music)., it was an addiction at one point and if deprived of other things it could become one again, but i do not see that. i t is not comparable to alcohol in pleasurability for me, but addiction is not always [parallel to pleasurability. i would say i was addicted to video games at one point too.

alcohol dulls the sensation of my hands, so i cannot combine it with the hand-based stims. but i remember stimming doing some other things that involve visual and other tactile input with a very low but nonzero BAC that i dont think would be interesting to me if completely sober.

more thoughts

edit
10:13, 27 July 2024 (UTC)

it's occurred to me that i may be unusual even among autistics in how much pleasure i get from stimming. i actually doubt this ... i think many others, perhaps a majority, are just like me, but that even with our somewhat odd social skills we understand that it's embarrassing to stim in public, or even to talk about it, and so stimmers just dont bring it up even amongst each other. there may be some social media groups that i could find.

but since i've shown addictive tendencies towards alcohol, perhaps i have addictive tendencies in stimming too, even above what other autistics have. it's also possible that my high fever euphoria has something to do with this, and that my brain might be wired differently from most people, whether autistic or not, and therefore i am unusual in two different ways that interplay. i can at least say i've never heard anyone else with autism describe being so addicted to stimming that they tricked their parents into driving them to a store to buy stim toys, claiming to be shopping for something else. but Reddit's staple man, who did not claim to have autism, did something even more extreme than this, so it's clear i'm not wholly alone.

either way, it seems if stimming is pleasurable for most who do it, people are largely unaware of this. our article, and other resources elsewhere, keep talking about how stimming is an escape from sensory overload, never mentioning that it's a pleasurable activity at all. is this honestly what scientists believe, or is this a sort of noble lie intended to protect stimmers, especially children, from parents and other caregivers who might see it as no different than masturbation or perhaps even drug use?

music

edit
21:44, 26 October 2024 (UTC)

perhaps if explaining to someone new to the subject, i'd say that stimming is just an extension of what most people do when listening to music. from minor head movements to dancing, all stims resemble these same things, but are coordinated to things other than music.

bath toy video

Updated 18:29, 6 July 2024 (UTC) (originally written Nov 2023)

My mother once recorded me playing with bath toys, but the video is lost. Older information here.

Stims I have no interest in

edit

oral stimulation

edit

this seems to be big lately, with chewelry and similar things. This may be a combination of three things:

  1. an expanded definition of stimming (both in the sense of including non-autistics, and of including more behaviors as stimming for both autistics and NT's)
  2. awareness of a common behavior
  3. the marketability of a product.

It may be that oral stimulation was previously seen as unsanitary and largely ignored even if it was obviously common. I do remember talking to other autistics and hearing that they often bit and chewed their hands and feet, and I briefly mentioned my own skin-chewing habit (developed from a thumb-sucking habit) before deciding it wasn't really a stim because I had been thinking at the time that only hand-based stims counted as stims. But it makes sense that both the hand and the mouth would have stims.

spinning, headbanging and rocking

edit

Spinning in circles used to amuse me just as a stim by itself, but I have lost interest in this.


I dont think Ive ever used the head banging stim, because I only do this while listening to music, "like everyone else". It is also possible that head banging is "not a stim" because people do it to block out sensory information, but if the definition of stim is open to debate, this is a meaningless distinction, so I will consider it a stim now. Currently our article at Stereotypic movement disorder contradicts itself.

I think I used to rock back and forth when I was young, but now that would simply make me throw up. again, this is something neurotypicals also do, since rocking chairs and swing sets both exist, just not in the same context.

blinking lights

edit

i used to enjoy turning a light rapidly on and off, but by age 5 i was apparently afraid of strobe lights i couldnt control, and even though i suspect i still would enjoy them if i could control them, the association between the pleasant and unpleasant stimuli may have turned me off (no pun intended). see below about traffic lights.

traffic lights

edit

I know I liked traffic lights enough that I was amused to hear there was a song called I Like Traffic Lights when I first heard about it as a teenager. (This was the early days of the Internet, so there was no way to play it. I was disappointed when I found the actual song some years later. But how could I not be? They werent singing about me.)

However, I suspect this wasnt really a stim. It's just that my parents somehow acquired a set of traffic light shells when I was very young, and those were my toys for a while. They were quite large and heavy, and in this era they had their colors in the glass, and I suspect all traffic lights were white underneath the shells.

i remember playing with a toy piano at night where green and red lights lit up with each note that played. Perhaps that was a stim, but yet again I have to assume neurotypicals would also enjoy this sort of thing (LiteBrite etc) and just be less likely to admit to it.

10:05, 27 July 2024 (UTC) coming back to this, i may have been stimming with the traffic lights after all, as I've since remembered that both my sister and my mother (separately) made fun of me for it, and that i had a dream involving a traffic light that i believed was real for quite some time. but i've lost the memory of what i might have been doing, and IMPORTANTLY, i still think it probably related to the large, shiny traffic light shells, and not to the more common stimming behavior that would involve standing in front of a blinking traffic light.

Sensory play

edit

Sensory play seems to be big nowadays. it's possible it always was, but didnt have a name until recently. like I said, LiteBrite was around when I was a kid, and its popularity seems best explained by the fact that it has lights, and that's pretty much it.

Im surprised there is no page yet for sensory play or stim toy. The latter shows the more mainstream usage of stim and would likely be just a redirect to the former rather than being about autism.

This has nothing to do with sensation play.

I wondered if I would have to write about the similarity between stimming and sexual play (and masturbation) sooner or later. I dont think the stims typically found in autistics overlap with sexuality in any significant way. If anythiung, someone who grew up playing with slime would find slime a reminder of chldhood and therefore a turn-off. But everyone's mind is different. (Likewise I dont think there is any overlap between stimming and masturbation, perhaps because masturbation cannot be prolonged the way stimming can.) essentially, this confusion only exists because the termninology overlaps. stimming is no more the same as masturbation than it is the same as taking stimulant drugs.

chewelry ~ wikt:chewelry

edit

This site refers to OCD's behaviors as stimming, but still carefully distinguishes them from the stims of autism.

hand washing post in an autism subreddit not related to OCD compulsive hand washing. drumming is probably a typo for stimming since there are other typos in the post. In the comments are other people talking about the same thing. i found this by searching for something like playing hands water autism because otherwise the OCD sense dominates even without OCD in the query string.

File:Tall_Autism_Happy_Hands.png

i will keep my distance but i believe the speaker in this video is wrong. Not everyone with autism sees flickering fluorescent lights (and many who dont still flap their hands), the explanation doenst make sense (111011101110111 overlaid with 110110110110110110 does not produce all 1's), and some people enjoy strobe lights.

assorted papers

edit

most google scholar papers are inaccesible for me, and maybe some of whati can access will be inaccexssible for others. even so:

  1. A Serbian study indicates that LFA's stim more, boys stim more, and younger children stim more, but that, oddly enough, students in mainstream education stim much more than students in special education. The paper's author seems to deny this in writing it up, and it may be that if true, it's because mainstream school teachers cannot easily tell their students to stop.
    1. This paper says that adults actually stim slightly more than children, though here I wonder if, as above, it's because nobody's going to tell a grownup they need to stop. Sample bias is always a problem when matching children against adults, since adults are more likely to stand out and need therapy. Also note that this study was not for people with autism specifically, although it does mention that autistics had higher rates of stimming than those with other sensorimotor conditions.
