High functioning versus low functioning autism
High versus Low Functioning depends on the nature of the ‘autism fruit salad’ underpinning the diagnosis with autism.
These ‘autism fruit salads’ can be standard or exotic, simple or complex, small or large quantities or pieces, separated contents or very mixed up.
High Functioning Autism
Asperger’s is usually when someone has Emotional-Social Agnosia and so cannot process facial expression, body language or intonation.
This restricts their involvement in the social-emotional realms of life so they compensate via intellectual interests, pursuits and abilities.
If they also have Simultagnosia they may struggle to process when two people are speaking with each other, tend to be visually rather mono-track, struggling to multi-task. If they also have some auditory agnosia, they’ll find that fans and external noises interfere with their ability to understand verbal information. If they have Dyspraxia or Dysgraphia, they’ll be clumsy, have motor planning problems and poor handwriting. Some will have face blindness, making it difficult to make or keep friendships. Being more stressed than those without information processing challenges, they will be more prone to sensory hypersensitivities than other people.
If they ALSO had oral dyspraxia, speech apraxia, Selective Mutism or learned dependancy leading to late speech (ie not speaking by age 4) then they would speak later than those diagnosed with Asperger’s and some may be diagnosed as HFA even if a percentage of non-autistic children also won’t speak until age 3-4. Although if verbal language is clearly normal at the time of diagnosis and shows no signs of significant ongoing language processing disorder at the time of diagnosis, early history of late speech by age 3-4 would likely not change the diagnosis from Asperger’s to HFA. The more present signs of significant ongoing language processing disorder at time of diagnosis, the more likely the diagnosis will be Autism rather than Asperger’s Syndrome. Whether this is High Functioning Autism (HFA), Low Functioning Autism (LFA) or in the Moderate range midway between the two, will depend on the range and degree of functioning challenges at the time of diagnosis. Some people in the LFA group move into the moderate range and may have some skills in the HFA range. there have been reported cases of some in the HFA and even Asperger’s range who have later ended up functioning in the moderate or LFA range due to breakdown, substance abuse, acquired brain injury, neuroleptic abuse, brain infection, or severe CFS.
So what is so called Low Functioning Autism?
The levels of motor planning problems with Dyspraxia could be so disabling as to be on a par with mild-moderate Cerebral Palsy.
They may have all the same agnosias but additional Semantic Agnosia, Form Agnosia, Associative Agnosia, Face Blindness, all of which may make them significantly meaning blind and struggle to learn visually as well as alienated from faces and finding people interchangeable if not for smell, tone and movement and this will make these people LOOK more autistic, be more likely to remain uneducated because pictorial learning won’t be accessible for them and without the capacity to externalise thought through the use of gesture, typing, or representational objects, they may not even know of their own intelligence, let alone others knowing of it. If they have Apperceptive Agnosia, they will also struggle to draw which may lead others to imagine them as retarded even if they can produce beautiful abstract works.
If they also have not only auditory agnosia effecting the perceiving of non-word from word sounds, but also Auditory Verbal Agnosia and Visual Verbal Agnosia, they will also be meaning deaf to what they hear as well as meaning deaf to what they read – yet often still able to ‘scan read’. This will commonly lead to either no speech or ‘dysfunctional speech’ (ie Semantic Pragmatic Disorder) and avoidance of reading, or fluent reading without comprehension. Both of which can lead others to presume mental retardation, emotional disturbance etc. It may also lead them to be presumed incapable of typing, even though expressive channels may actually still be relatively intact. If the person also has Alexia, they may be unable to perceive the written word as made up of letters and if this is combined with other significant visual and verbal agnosias they may struggle to demonstrate their intelligence through typing.
If the same person also had significant gut, immune, metabolic disorders which lead to ongoing brain toxicity, fatigue or being brain starved, this would reduce that person’s functioning level until these are addressed. The style with which meaning deaf-meaning blind people with autism learn will be more likely to be kinesthetic, musical or logical rather than visual-verbal, meaning they are less likely to be accomodated in mainstream educational settings. If they are also solitary and not social learners, the degree of their challenges will increase this and solitary learners are already poorly accomodated in most educational programs.
Similarly if the same person had significant untreated co-morbid mood, anxiety and compulsive disorders dramatically channeling their resources into exhausting self management at best, chaos at worst, this would greatly reduce functioning until treated.
If the same person also had severe Hypotonia they would be very floppy in their body, easily fatigued and if combined with Tactile Agnosia, Finger Agnosia or Pain Agnosia, they may appear to have little sense of their body, little identification with it and a poor relationship between volition and action through the body. Combined with severe Dyspraxia and Simultagnosia, they may also be unable to experience body messages relating to toileting or switch perceptual channels when involved in another task in order to attend to toiletting. Where this is taken as reflection on their intellect this will usually lead people to presumption one is low functioning if not mentally retarded.
Chronic stress, emotional dysregulation and burden on information processing will put up the tempo of not just sensory hypersensitivities but also any natural personality trait. Those with extremely large, complex ‘autism fruit salads’ will be more likely to display a range of personality disorders as their natural personality traits display in the disorder proportions for each trait. As these then become labeled ‘the autism’ it can escalate the same issues if the person feels their personhood is being devalued.
Because those with more severe challenges struggle to manage on many more simpler levels, opportunities for the environment to take over, outshine, pursue relentlessly, fixate on the person as a case or pathology or build pathological levels of co-dependency, this can dramatically increase learned dependency in those with some personality traits, withdrawal in others. Self injury can escalate where this contributes to Dependant Personality Disorder where it is used to force the environment to take over, self injury due to extreme sense of helplessness where the environment constantly outshines the individual by taking over, or self injury where a solitary personality feels constantly pursued and finds self injury causes the environment to back off. All of these responses can be considered part of being ‘low functioning’.
Essentially, those in the low functioning group may be as intelligent as those in the high functioning group but are more likely to perform badly on the same IQ tests and may have great potential in fields far different to those people in the high functioning group may excel in but be socially more unlikely to get those opportunities or make the social contacts which would lead to those.
Who speaks for whom?
I had a letter from Adam Feinstein of Looking Up magazine who wrote:
Hi Donna,
I’ve just been asked by someone in France whether there is a fundamental difference between a non-verbal individual with autism who appears to be cut off from the world and a higher-functioning autistic person who is able to write articulately about his or her experiences. What is your view on this?
I felt the question was an interesting one so wrote:
Non-verbal could mean so many things.
It could mean infant depression with acute social anxiety and selective mutism.
It could mean brain starvation and toxicity due to gut/immune/metabolic disorders
it can mean dominated with mood, anxiety, compulsive disorders till everything is too chaotic to dare build bridges through communication.
It could mean lack of simultaneous processing of self and other together with oral dyspraxia.
It could mean someone meaning deaf, perhaps also meaning blind who has been unable yet to learn the one word-one meaning system.
If a high functioning person has never been any of these things, then they are psychologically, cognitively, perceptually very different to a high functioning person who has once been at least some of these things during a conscious phase of childhood (ie after the age of 5)
If a high functioning person outgrew such stages before the age of 5, they may have been unlikey to have had the neurological development to retain a comprehensive and cohesive memory about daily life, perception and functioning to later convey that stage in anything but glimpses.
On this basis, anyone diagnosed as psychotic or autistic under the age of 3, and who was functionally non-verbal and lacked simultaneous processing of self and other, but who outgrew such experiences by the age of 3-5 would likely not really understand what it is to take for granted what it’s like to live one’s daily life as a grown person this way.
For example, I came to understand the one word-one meaning system at age 9-11. Before this I was largely meaning deaf.
By age 30, I came to hold a simultaneous sense of self and other for 45 mins, long enough to become consciously aware of this process (I had had moments, minutes of it previously, but not enough to become consciously aware of it enough to grasp it as a system or something to seek). At age 9-11 one is relatively a grown person, at age 30 one is certainly a grown person
but at age 3 or 5 one is still developing fast so one lets go of the earlier phases. At age 9-11, whatever cognitive, perceptual and communicative stage one is in, this is more like just ‘what life is’, ‘what being a person is’.
I’m now someone who can speak fluently. But there’s much of me finds this a foreign system, foreign language, and its often tiring. I’m far more about being and doing. This is perhaps because I came to understand language quite late (had a massive stored repertoire of stored strings before this) or it could be the other way around, that I was late to develop functional speech because the semantic-pragmatic system was not my natural neurological strength.
Just because I can learn to do handstands doesn’t mean I was designed to walk on my hands.
So I don’t easily see my experiences reflected in those who outgrew these things by age 3 or 4, even though I may be in the same HFA group as them now. Being ‘feral’ until such a late age changed me in fundamental ways, neurologically I’m more rusty than earlier developers, my batteries go flat quicker, my natural instincts work in other ways, my soul is geared for a more animalistic style of processing and responding and it takes more to consciously try and dominate that in order to survive in the non-autistic world. At the same time, I’m in a distinctly different group of adults to those who are still in the developmental phase I left by late childhood and those who are still functionally non-verbal adults.
It may also be that many people with Asperger’s can’t grasp the world of meaning deafness, meaning blindness and a time when there was no concept of simultaneous self and other. Some people with HFA, however, can (generally those who developed communication late childhood-puberty) but most verbal HFA people I’ve met either began in the HFA range or outgrew all but their behaviours by age 4.
Autism, however, is not behaviours. One can become attached to behaviours long after their cause or necessity has passed.
And one can dump behaviours even when the causes persist. Educationally, families and professionals want to learn about the sensory-perceptual and cognitive challenges. Recounting one’s old behaviours as a toddler, without explaining their perceptual, cognitive or communicative roots, is entertainment not education and adds little to understanding in the field.
Autism has become trendy, like dolphins and unicorns, and I think we need to distinguish identity/culture politics from the condition as well as look at where the two meet. The cultural phenomenon is real and often useful to those who gain emotionally and socially from it. All families of those with autism need to see and respect the PERSON and not fixate on pathology until they erase the personhood and equality of the person with autism. At the same time, autism as culture is often not where families of severely challenged kids with autism are living day to day.
Yes, it IS a spectrum. Yes, there are different autism ‘fruit salads’. And we all have much to learn from each other. We learn that best when we talk as representatives of our own realities without presuming we speak for all with a shared label.

“If they also have Simultagnosia they will struggle to hold a simultaneous sense of self and other”
This is not Simultagnosia. It has nothing to do with ANY “sense” “of self and other”. And when people develop this condition, they do not also suffer a loss of social and other functional abilities.
It has nothing to do with any “sense of self and other”, instead, it is a recognition problem, and of visual objects, not senses of self and other people.
“Inability to recognise multiple elements in a visual presentation, i.e., one object or some elements of a scene can be appreciated but not the display as a whole.”
It is a visual object problem, and one of RECOGNITION.
when two people are talking, I see one person’s mouth moving and noise coming out. Then I see another person’s mouth moving and noise coming out. I see the person I’m needing to speak to has stopped moving their mouth and making noise so I address them. They snap at me, ‘can’t you see I’m speaking to someone. I answer, no. If I’m further away, I can get it, but the closer I get the harder it is to hold processing of two things, be those objects or people. This is the same problem I have with cooking and running a bath, different components keep seeming to go ‘missing’ from consciousness. If my hands are on them, it works, but once my hands are off, things get lost. Parts of what I’m seeing just seems to become ‘art’ so this leads to fire and flooding. It would be amusing if it weren’t so annoying. So, sure, maybe you’re right, that simultagnosia can’t explain a lack of simultaneous processing of self and other, but it seems to me just an extension of the same issues in holding track of two people in a single context or two objects. It is certainly the case that when processing ‘other’ I’m regularly losing the processing of ‘self’ and vice versa. Perhaps there’s an additional form of agnosia that covers this, but until it’s got a name, personally, I see it as functionally little different to the regular loss of processing simultaneous people, objects and visual context. Thanks for your feedback in any case.
it’s also possible that just as there is Visual Verbal and Auditory Verbal agnosias, that we currently know of visual simutagnosia but we may find there are other forms. For example, I can hear intonation and words but I process either one or the other. When there is significant intonation I struggle to process the meanings of words. hence I prefer men’s voices of rather monotone ones. I also very much rely on intonation to recognise people (I’m largely face blind and rely on movements and intonation) but when tuning into the meaning of words, its like the intonation has gone. Until late childhood, I had delayed echolalia of long strings from TV shows, but not with meaning, but all complete with each character’s intonation. After gaining meaning from words after age 9-11, I can still do this and shadow speak people’s voices, but not as astoundingly and still when doing so I have no idea WHAT they are saying. So perhaps there is an Auditory Simultagnosia too but those with it may be too autistic to acquire functional communication and write or speak about it, who knows. As for loss of other when processing self, this seems to be a split between sensory systems where, when using body and thinking in order to express oneself, there’s a loss of visual and verbal processing relating to perception of ‘other’. They just become ‘art’ or ‘stuff’. Then when in all other no self mode, it’s as if perception of body and thinking has left. What remains, however, is a kind of computation skill, an ability to map the patterns but with no access to one’s body responses to know what one feels. I was mostly in that state until my 20s and first got enough simultaneous sense of self and other to know it existed in other people’s perceptions when I was in my 30s, which I wrote of in Everyday Heaven.
I wrote of it in Autism; An Inside Out Approach as ‘systems forfeiting’. But if one has a range of agnosias – visual, auditory, verbal, tactile – then there could be interactions relating to compensations which cause such strange perceptual experiences.
So agnosia in general, I think, is a problem of recognition, not meaning. In prosopagnosia (face blindness)…well obviously the person is not “blind” to the face itself…but rather to the recognition of the face, and, not to the meaning of the face. So the face has meaning, the facial expressions have meaning, the face and facial expressions can be seen…it’s that the face is not recognized. Reminds of of Alzheimer’s Disease…the spoon is seen, it has meaning, it’s functioning is understood, it can be used, it is sought out for it’s purpose, but, the person doesn’t recognize it as a spoon. So it has meaning in all senses, except it isn’t recognized.
I think the meaning-blindness you discuss is different than agnosia. In the agnosias there is meaning. A person, and the spoon, have all the meaning as a person and spoon…they are just not recognized. Well actually, for the person, while he/she is recognized as a person, he/she is not recognized for who he/she is…so a mother might not recognize her son (I’ve seen a case study of this on TV), but still the mother knows the boy is a person, and can fully interact with him, understand all aspects of social interaction, facial expression exchange, communicative exchange, etc. Seems the meaning-blindness you speak of is far more devastating and complex than agnosia.
I actually have some difficulty understanding the nature of this recognition, that is, difficulty with imagining what I mentioned above.
With me the object is seen, the form, and if it’s in it’s ‘placement’, then I know what it is. If it’s outside it’s usual placement, it’s about 30-50% chance that I’ll recognise and if its of a color or size I’m not use to, even less. If I see someone use something, I can tell from the actions what it is, no problem. Similarly, from tapping, flicking, rubbing or smelling I know quite quickly what an object is. If that’s not agnosia, certainly help me out with a word for it. I’ve called it object blindness, context blindness, meaning blindness. But the word agnosia helps parents of those with similar to understand the situation easily.
As for faces, I used to see them a bit at a time, struggling to process the eye, nose and mouth together, each bit would be ‘there’ but just as if it were ‘art’ rather than a concept. With tinted lenses I can now see faces as a whole, basically they cut out certain light frequencies, allowing my brain more time to process what I see. Peripheral vision works similarly through limiting the number of rods used to see.
But even with the face seen as a whole, there’s very little visual memory. I can use serial memory for movements and space, which means I can basically replay anywhere I’ve moved and touched, but this lack of visual memory thing means that people, like objects, if seen out of context or they change their usual form (ie clothes, hair, glasses, etc) they become strangers.
there is semantic agnosia, which is meaning blindness. This is different to associative agnosia. Semantic means one can see the form but little idea what they are seeing. Associative is like your spoon example. I don’t have too much trouble with that one, but most things bowl-like become bowls, most things that are cup like are interchangeable, including glasses, for a long time chickens and ducks were in the same group and then pidgeons were seen as chickens (because they weren’t on water) and swans as long necked ducks. So I understand the associative thing too.
I think what I have is multiple agnosias, which does make the issue more complex, perhaps very devasting until one learns to compensate, as I have… people with such agnosias should be inspired by Helen Keller…. and so where there’s multiple agnosias, the situation isn’t as clear as in a person with one or maybe two forms.
Meaning deafness and meaning blindness appears to fun on my father’s mother’s side where there are several people on the autistic spectrum. But there were many toxicological incidents, starvation of oxygen and illnesses related to two primary immune deficiencies which likely contributed. Nevertheless, the point is what one CAN do and whilst some very simple tasks are always 50-50 of at best 70-30 in terms of success, when I compare myself with my OWN group, I’m doing damned well so there’s no need for me to get distressed at my failure rate on simple tasks…many in my group gave up trying long ago or had others simply take over until that was ‘life’. If that’s ‘luxury’ I’ve done well not to have had it.
But even with the face seen as a whole, there’s very little visual memory.
You’ve got that right. My mom used to tell people that the reason I couldn’t recognize people by face was I’d seen faces only in pieces. But even with tinted lenses that helped me see faces as more of a whole, I could still not recognize people by face.
My son is definetly a fuit salad!
Your explanations are one of the best i have ever read. Thank you.
Hi —
Your posts make me wonder how common various forms of agnosia are in the autistic population. Interesting. I’ll mention that to my professors next semester (I’m a cognitive science major at UC Berkeley)
On another note, you may be interested in making this distinction: ‘face blindness’ can be divided into two different parts, and it’s possible for a person to have one part but not the other part, or the two parts to different degrees. First, there is the ability to recognize one person’s face from another. So, for example, if I am introduced to someone at a party, can I recognize her at a later time.
The second part is the ability to read the emotional expressions on a face — so, whether I am viewing my mom’s face or a stranger’s face, can I pick apart which emotion is being felt from facial expression alone?
yes, there can be many factors at work
prosopagnosia is specifically inability to recognise faces
social-emotional agnosia is inability to perceive facial expressions
there is also Form Agnosia which is inability to perceive several parts at a time – ie visual perceptual fragmentation
I wrote about the latter in Like Colour To The Blind when I was told it was part of my Scotopic Sensitivity Syndrome
and whilst tinted lenses have allowed me to see faces now as a whole
its clear that several decades of seeing them piece by piece does nothing to combat prosopagnosia
and I also feel its time we recognised Form Agnosia for what it is
seeing the part and losing the whole
a form of visual perceptual context blindness
