Autism, Semantic Agnosia & “The Eyes That Don’t See”

Shorts

The Eyes Are Deceptive?

Think about it a person who eye’s are organically “normal” and the ability “see” from an psychical perspective is there but the brain is not able to process visual information that is coherent and meaningful.

Reality vs. Context? The Hidden Link

As a child association was created through my body this could be through objects and or people. Touch gave me a reality and context that my eyes could not the contours of what touched beamed into my inner world as a way of saying “hello” to the outside from inside and secret bridge that was being made every time.

Movement, Mapping and Tactile Association

I was eager to be bare foot and “mapped” out my surroundings, movements, twists and turns around the “dead space” that enveloped in was both my enemy and my friend all at once. Touching, licking, sniffing, tapping and rubbing gave “life” to everything around me on an unconscious level of was working out world.

• This is the most studied type: easier to detect.
• Stimuli misrecognized visually, can be recognized:
– through tactile manipulation
– from verbal description
– based on its characteristic sound or noise
object
early visual processing
image viewer-dependent
object-centered (3D)
(2 and 1/2 D)
(
episodic structural description
)
structural description system
semantic system
output phonological lexicon
object naming

A Blindism

One could call this a “blindism” a state in which visual perception is not giving the associative signals and/or visual association of what an object “is” regardless of where you find it, what angle you see and so forth. This could lead problems with context and a distortion of memory.

Conclusion

As an adult I still rely more on my movements that what I am “seeing” this means that can still get lost in my surroundings but with my tinted lenses this is able to keep my conscious mind on track with meaning.

Autism, Visual Distortion, Non-Visual Thinking & Image Break-up

There are many people on the spectrum such as Temple Grandin that have strong visual memories not only for fact retrieval but in her case she has used her visual way processing to help her with her career in animal slaughter.

CONNECTING WORDS, SYNESTHESIA & LANGUAGE 

Some people on the autism have problems with not only processing visuals in “real-time” but also accessing it, contextualising it and having what I call “image retrieval” this means the person in question may not only have problems processing and internalising what is around them (visually) they may well have issues with image retrieval this means they may not connect the image with word because they have no idea what the image is so there is no were for the “word” to or they may have an issue once they have processed the image to give it the correct word that is associated with it. For me words have to be associated with a “feeling” not emotional specifically but how the object for example “felt” as I am typing this will remember the typewriter by the “texture” of the keys that my fingers are touching.

MEANING AND INFORMATION “BLOCKAGES”

This may sound and look odd for the onlooker and rightfully so – but is the person has so many sensory “blockages” touch in the context of “meaning” may well be one of the only ways in which they can access the “world” in way which is not only comforting (for some) but meaningful its relevance.

SEMANTICS AND PERCEPTION

This may well not be just restricted to touch and feeling it may well also include licking, sniffing, mouthing too to objects, people and the physically surroundings. Visual break-up may look like the child is blind which in my case my Mum thought I was which would indicate I was showing behaviours of a blind person. (as well as a deaf person because of auditory processing).

Visual Perceptual Disorders, Visual Agnosias, Motion Perception & Tinted Lenses

Me Looking to SidePlease note – this is from a personal perspective of visual perceptual issues 

Eye Tracking 

I met a lady at an autism conference this year who has expertise in sensory integration I described to her how I “see” the world and access it – she said there is a simple test it involves a pen at the midline of your focus and vision as she moves the pen she asks me to track the pen my eyes darted and had to “re-focus” as I could not follow the movement properly and process the visuals either.

Visual Perception Disorders 

This would also make sense of why I see things in pieces (simultagnosia), problems processing faces (prosopagnosia), integrating visual information, visual semantic recognition (semantic agnosia). I found this revelation very interesting and informative.

Cortical Visual Impairment/Disorder Article 

Not all types of visual deficits caused by CVI will affect visual acuity. For example, in cortical visual dysfunction (CVD)16, the predominant visual deficit is not visual acuity loss, but rather disturbances in visual perception and integration. In higher-functioning children with CVI or CVD, specific visual disorders such as agnosias may be diagnosed. These include cerebral motion blindness or cerebral akinetopsia (the inability to perceive moving targets), simultanagnosia (the inability to focus on more than one visual object at a time), central achromatopsia16 (color desaturation), prosopagnosia (difficulty in recognizing faces), topographic agnosia (problems with orientation; see section on rehabilitation), and astereocognosis (difficulty with depth perception)17. Thus, although not all children with CVD have associated CVI, certain children with CVI (with loss of visual acuity) may show signs of CVD

“The most common cause of CVI is an hypoxic-ischemic injuryl-3,10,19,20. At least 60% of children with neonatal hypoxic-ischemic encephalopathy have cerebral visual impairment12. Hypoxia (lack of oxygen) or ischemia (tissue death due to loss of blood flow, and thus oxygen deprivation) in the preterm baby leads to a characteristic injury of the brain, namely periventricular leukomalacia (PVL)21,22, which can be detected by MRI.”

This would make sense of the the following visual perceptual issues I have

  • Akinetophsia (motion blindness) – I believe I could have this as a result of simultagnosia (a problem with visually processing integrating the whole picture) this can lead to a “juddering” effect with my vision
  • Simultagnosia (object blindness) – “seeing” things in “bits” and or “fragments” not being able to integrate the pieces into meaningful chunks this could also be considered a form of context blindness.
  • Prosopagnosia (face blindness) – Not being able to recognise a person by their face this can lead to the persons using other forms of “recognition” such as voice, patterns of movement, placement, touching, sniffing hair, name tags etc.

What Has Helped?

From a personal perspective tinted lenses have had a great impact on how I process visual information and integrate it. The lenses have also  helped with

  • Body posture
  • Movement of my legs (not so “heavy footed”)
  • Reading and writing (dyslexia and dyscalculia)
  • Light sensitivity (sensory integration disorder)
  • Eye contact
  • Concentration and focus
  • Integrating visual perceptual information (even if I don’t understand the semantics/meanings this still helps)

Remember All Autism “Fruit Salads” Are Different 

That also includes not only what the fruit salad is made up of but also the origins that made them.
