INSIDE PERSPECTIVES of AS & Neurodiversity

 

SENSORY PROCESSING

 

    Many on the autistic & neuro diversity spectrum have sensory differences - either in perception or processing, or a combination of both. These differences are probably the cause of many of the seemingly odd reactions and preferences common to people with ASD, ADHD etc. 

 

 

SID/SPD

 

   The basic assumption behind SID (‘Sensory Integration Dysfunction’) or SPD (‘Sensory Processing Disorder’) appears to be that there is an ideal level of sensibility/sensory receptiveness which ought to be the same for everyone, regardless of age, temperament etc. The hypothesis is that the incoming information from the senses are received correctly but processed abnormally, leading to either of the following:

 

·  Hyper-sensitivity (‘sensory over-responsiveness’).

·  Hypo-sensitivity (‘sensory under-responsiveness’).

·  Sensory-seeking.

·  Sensory discrimination difficulties.

·  Balance & motor problems.

 

   In some cases of extreme hyper- or hypo-sensitivity, I believe this hypothesis has merit, especially when it comes to the more somatic senses like touch, sense of movement (vestibular system) and position (proprioception) - which also seem to be the most easily treated with Sensory Integration Techniques.

 

   However, there are also natural, genetic variations in sensory sensibility that are perfectly normal for that particular body type or temperament. To generalise a little:

 

·  An extrovert, sensory, tactile, intense, high-energetic ‘Hunter’ type individual may have an innate and perfectly valid need to get hands-on sensory experiences of the world in order to be adequatly stimulated and informed.

 

·  An introvert, intuitive, creative, Highly Sensitive Person is often born with a more delicate nervous system and more well-developed or finely tuned senses all around. A case of enhanced sensory perception rather than ‘abnormal sensory processing’. Such a person usually only needs a calm environment and to be treated with care to feel & function just fine.

 

   “Why is it not okay for a person to be delicate?  Why do we prize delicate objects, but not delicate people?  Why do we recognize that a delicate silk shirt must not be treated the same as a pair of jeans but do not recognize that a delicate child has special care instructions?

 

   “If we accidently put our delicates through the regular wash and they fall apart we admit it is our fault the clothing is damaged.  When we give delicate people the same treatment as others and they fall apart we criticize the delicate person for not being tough enough.”

SENSORY SENSITIVITY / HSP

 

   Exceptional sensitivity to sounds, vibrations, smells, tastes, textures, touch, temperature, wind, barometric pressure & humidity, certain colours, bright light, fluorescent light, flicker, clutter, movement, crowds, stress or pain, is very common among autistic & neuro diversity spectrum people, but you can be a Highly Sensitive Person and have extra well-developed senses without being autistic. According to Elaine Aron, this is a perfectly normal trait that is inherited in 15 to 20% of the population.

 

   Naturally, being able to consciously perceive more than most people can be both painful, enjoyable or useful, depending on the situation: 

 

   “I have always, in the past, enjoyed good smells, but I'm finding that my sense of smell is a growing problem as I age. I'm getting more and more sensitive with it, to the point that I almost can't take any smells at all. I can detect smells that no one else can... and believe me, it isn't fun!! Even the smells of my own husband and children are often unbearable to me.”

- Cathy, adult Aspie from USA

 

   “I am very sensitive to quick temperature changes. For me it is horrible to first have a shower in lipid water and then dry oneself in room temperature, I freeze to death before I get my clothes on. My facial skin doesn’t seem to have the same protection against cold that others have. When I go out in freeze temperatures I feel like I’d like a thick robber’s hood with just holes for the eyes. My skin is sensitive to heat too, I don’t feel well when it’s warm, over 20 degrees Celcius in the summer, and in the winter not under zero Celcius. Autumn and spring are my seasons, in other words.”
