Title: Different Sensory Experiences Different Behaviour
1Different Sensory Experiences Different Behaviour
2Sensory Difficulties
- In the sense of taste we find almost invariably
very pronounced likes and dislikes. It is no
different with the sense of touch. Many children
have an abnormally strong dislike of particular
tactile sensations, They cannot tolerate the
roughness of a new shirts, or of mended socks.
Washing water too can often be a source of
unpleasant sensations and hence of unpleasant
senses. There is hypersensitivity to against
noise. Yet the same children who are often
distinctly hypersensitive to noise in particular
situations, in other situations may appear to be
hyposensitive. - - Hans Asperger (1944)
-
3Sensory Overload
- The corridors and halls of almost any mainstream
school are a constant tumult of noises echoing,
florescent lights (a particular source of visual
and auditory stress for people on the autistic
spectrum) bells ringing, people bumping into each
other, the smells of cleaning products and so on.
For anyone with the sensory hyper-sensitivities
and processing problems typical of an autistic
spectrum condition, the result is that we often
spend most of the day perilously close to sensory
overload. - (Sainsbury 2000)
4Possible Responses to Sensory Difficulties.
- The F words
- Fear
- Flight
- Fight
5 Triad of Impairments and Sensory Differences
Communication impairments
Impairment of social interaction
Sensory processing
Flexibility of thought and behaviour
6The Sensory Integration Process Register, become
aware of the sensation. Orientation, pay
attention to it. Interpret,using current
information and referencing past experiences for
comparison. Organization, occurs when our brain
decided what to do in response to the
sensation. Execution,What we actually do in
response to the sensation
7The only way you will understand is if I put my
brain in your head, then you will see things
properly.
8Sensory Processing Difficulties
The perception of sounds
-
- My hearing is like having a sound amplifier
set at maximum loudness. My ears are like a
microphone that picks up and amplifies sound, I
have two choices, turn my ears on and get deluged
with sound or shut my ears off. - (Temple Granding)
- A sudden noise (even a relative faint one)
will make my heart race -
- It is impossible for an autistic child to
concentrate in a classroom, if he or she is
bombarded with noises that blast through his or
her brain like a jet engine. -
- Another trick my ears played was to change
the volume of sounds around me. Sometimes when
other kids speak to me I could scarcely hear them
and sometimes they sounded like bullets. - (White and White)
-
9-
- I was living in a world of day dreaming and
fear revolving about myself. I had no care about
human feelings or other people. I was terrified
to go in the water swimming (and of) loud noises. - (Volkmar and Cohan)
- Many bad behaviours are triggered due to
anticipation of being subject to a painful noise,
bad behaviours can occur hours before the noise -
- What do autistic children hear ? Sometimes I
heard and understood and other times sounds or
speech reached my brain like an unbearable noise
like on a rushing freight train. Noise and
confusion of a large gathering of people
overwhelmed my senses. - (Temple Grandin)
10Possible Resulting Behaviours
- Becomes upset or runs away from unexpected noise
- Doesnt like the sound of certain electrical
appliances e.g. vacuum cleaners, kettles. May
seek to escape or remove items. - Walks around Humming and or shouting to block out
unwanted noise. This may cause problems in class
or out in public. - Appears to ignore voices or certain sounds may be
perceived as rude. - Finds it difficult to shut out unwanted sounds
e,g, other children in the class - Looks confused and doesn't know what sounds to
pay attention to
11Ways Forward
- Try to provide warning of loud noises
- Ensure that you have the childs attention before
giving important information - Provide a visual cue when you require the child
to listen - Dont presume that the child can look and listen
at the same time - Provide a quite place for the child to retreat to
in the home or school - Provide the child with a means of indicating that
they cant cope with sounds/noise - Provide the child with earphones to block out
unwanted sounds
12Ways Forward
- Provide the child with background music to help
them stay calm. When I am feeling angry and
despairing of everything, music is the only way
of making me feel calmer inside. (Jolliffe 1992) - Provide the child with music to block out
unwanted sounds - Vary the tone of your voice to maintain interest
and gain attention. - Only have one person at a time speaking to reduce
stress and misunderstandings. - Dont have TV, music on at the same time
13VISUAL PERCEPTION
- Spatial perception difficulties
- I used to hate small shops because my eyesight
used to make them look as if they were ever
smaller than they actually were. (White and White
1987) - Difficulties with colour
- I also remember one Christmas when I got a new
bike for a present. It was yellow, I would not
look at it extra orange was added to it and it
blurred upwards making it look like it was on
fire. - Difficulties with light and lights
- Bright lights, midday sun, reflected lights,
flickering lights, fluorescent lights each seemed
to sear my eyes. Together the sharp sounds and
the bright lights were more than enough to
overload my senses. My head would feel tight, my
stomach would churn and my pulse would run my
heart ragged until I found the safety zone. (
Willey 1999)
14VISUAL PERCEPTION
- It may be because things that I see do not always
make the right responses that I am frightened of
so many things that can be seen, people,
particularly their faces, very bright lights.
Crowds, things moving suddenly, large machines
and buildings that are unfamiliar, unfamiliar
places, my own shadow, the dark, bridges, rivers,
canals, streams and the sea. - Jolliffe (1992)
15Possible Behaviour difficulties
- Sensitive to changes in natural light may find it
difficult to be outside at certain times of the
year - Uses fingers to filter light. This can limit
involvement in activities can draw attention to
the child. - Have difficulties finding what they are looking
for requiring extra time for activities - Problems concentrating when in a room with
fluorescent lighting, may engage in flight
activities. - Possible difficulties with certain colours may
avoid them or seek them out. - Bumps into things and people.
16Possible difficulties
- May prefer to use peripheral vision, in school,
when talking and listening when crossing roads. - Inability to distinguish between foreground and
background (can result in sensory overload not
gaining all information needed.
17- We are often part of the problem
- People everywhere,
- Talking, wearing bright colours.
- The talking is like the pounding of horses
hooves. - The bright colours are blinding,
- The talking hurts my ears,
- The bright colours hurt my eyes.
- Oh why cant people be quiet and wear dull
colours. -
- (Dianne Mear 1994)
18Ways Forward
- Try to identify colours that may cause a problem
for your child by observation and experimentation
and control exposure to them. - Try breaking up long corridors etc with colour to
provide a point of focus and so facilitate
movement. - Put tape on edges of steps to help with
processing depth - Allow to explore new environments and become
familiar with them - Have a area with reduced visual stimuli (tent
within a room) - Remind the child what and who to look at
- Teach the meaning of facial expressions dont put
pressure on to look at people faces.
19Touch
- Some episodes of bad behaviour were directly
caused by sensory difficulties. I often
misbehaved in church and screamed because my
Sunday clothes felt different. During cold
weather when I had to walk outside in a skirt my
legs hurt. The problem could have been easily
overcome by finding Sunday clothes that felt the
same as every day clothes. - (Temple Grandin)
20Touch
- Therese Joliffe preferred using touch to learn
about her environment because it was easier to
understand things through her fingers. Her
hearing and vision were distorted and provided
unreliable information. She was better able to
see if she felt items first. - I hated having showers as a child, and preferred
baths. The sensation of water splashing on my
face was unbearable. I still hate it. I would go
for weeks at a time without bathing and was
amazed when I found out that kids had a regular
shower, every day even.
21Touch Related Behaviour Difficulties
- Doesn't like the feel of towel on skin or being
splashed with water can result in avoiding bath
times or swimming. - Doesnt like teeth been brushed can result in
flight, fight or fright behaviours. - Becomes upset when touched particularly if
unexpected. - Doesnt like wearing new clothes or cloths of
certain textures. - Doesnt like getting hands dirty or food around
mouth. - Avoids activates that involve being touched.
22Ways Forward
- Gradually introduce new clothing over time.
- Involve the child as much as possible with
washing and bathing, allow the to control how
much pressure is used. - Try different lengths of clothing (shirts,
trousers) - Heavier blankets or foam mattresses may help with
sleep difficulties. - Observe the child's responses to different
textures in the environment and make adjustments. - Try to give warning of touch (first we wash your
hands then your arms) - Provide opportunities to receive deep pressure
when needed.
23Gustatory (Taste)
- Myles et al,(2000) more than one third of
children with AS avoided certain tastes that are
typical in other children's diets. - Would only eat certain foods
- Were picky eaters
- I hated anything that was slimy, like Jell-O or
undercooked egg whites. - Temple Granding
24Taste
- I had a big problem with food. I liked things
that were bland and uncomplicated. My favourite
food were cereal- dry with no milk pancakes,
macaronis and spaghetti, potatoes and milk.
Because these were the foods I ate early in life,
I found comforting and soothing. I didn't want to
try anything new. - Canned asparagus was intolerable due to its slimy
texture, and I didn't eat tomatoes for a year
after cherry tomato had burst in my mouth while I
was eating it. The sensory sensation of having
that small piece of fruit explode in my mouth was
too much to bear and I was not going to take any
chances of it happening again - Stephen Shore
25Possible Difficulties
- Will not eat certain foods
- Maybe sensitive to certain textures and refuse
them - May only eat foods of a certain texture
- May overfill mouth with food.
-
26Ways Forward
- Try to create a relaxed atmosphere at meal times
- Respect individual differences dont try to force
food on the child. - Introduce very small bites or portions of new
food try not to change both textures and tastes
at the same time. - Always proceed with caution and take advice
27Olfactory (Smell)
- 75 of young people in Myles study experienced
some difficulties in this area of olfactory
sensory sensitivity - Sensitivity in this area can bring about
Fright Flight or Fight response
28Possible Difficulties
- Finds it difficult to be in certain environments
due to smells (may be aware of smells we dont
pick up on) - Close proximity of people can be a problem due to
odours - Refuses certain foods due to smell.
- May use smell to make sense of their world.
29Ways Forward
- Use unscented products
- Try to identify smells that cause particular
problems and remove them from the home for a
period - Try to gradually increase tolerance to different
smells
30Proprioception
- The muscles and joints and joints send messages
to help us carry out basic movement functions
such as ,stand, sit, hold things and balance - This system allows us to carry out movement tasks
without looking.
31Possible Difficulties
- Difficulty maintaining good posture when sitting
or standing - Visually checks out hands and feet to ensure that
they are doing right thing - Shuffles a lot on chair
- Cant get comfortable on chair, in bed
- Difficulty climbing and descending stairs
- Gym can be a nightmare
- Difficulty finding his mouth/teeth when brushing
- Difficulty using right amount of pressure when
writing - Poor muscle tone
32Vestibular System
- Vestibular system is involved in movement,
posture, balance and coordination of both sides
of the body - Approximately 50 of children with A S
experience difficulties in this area - Can be hyper or hypo sensitive
- Hypersensitive children have difficulties with
anything that involves movement particularly
involving changing direction, speed. This group
can fear having their feet of the ground
(Gravitationally insecure)
33Ways forward
- Try using heavier items (plates, cups) so that
they are more easily registered - Provide visual information for sitting at desk
- Encourage the use of squeeze balls etc to develop
muscle tone - Provide opportunities for large motor activities,
pushing, jumping and pulling - Do activities that that encourage and develop use
of whole body and coordination - Consider the type of fasteners on clothing ,and
shoes - Use clay etc to develop hand strength
34Possible Difficulties
- Difficulties changing directions when playing
sports - May have difficulty changing speed
- May be afraid to have their feet off the floor
- May loose their place when reading from a board
or book - Putting trousers on may cause problems
- May turn whole of body to look at a person
rather than only head - Engages in bouncing and spinning activities
