This is one of several books that Temple Grandin, autistic herself, has written on autism. These are my notes of the points which struck me most. All her books are well worth reading.
Autistic people think in pictures
not words, but often talk out loud to help organize thinking, and may be able
to express conclusions in words. They tend to build a library of stock phrases
and sentences to use in conversation and, in common with others with
disabilities, need be taught even ‘simple’ things like getting dressed as a
series of small tasks.
Inattentional blindness – normal
people don’t see things if they are not expecting them. Autistics may see them
more often – as visual thinkers are more detail-oriented. But people always
seem to recognize sight and sound of their own name, large-sized objects and
cartoon happy faces (but not sad ones).
Need to take care not to assume animals
think like humans. Owner assumed dog felt guilt as always ran off when found
with rubbish on floor; but also ran off when taken into room with rubbish
already on floor – just associated rubbish on the floor with trouble.
Vision is important to animals;
monkeys can be trained as easily with a view out of a window as the reward as
with food.
Animal vision differs from human
vision, having a limited colour spectrum. Certain things ‘jump out’ for animals
and autistics, such as contrast in illumination – animals never like going from
bright light into the dark as it temporarily blinds them, although prey animals
(e.g. cattle) have good night vision.
Dogs have poor visual acuity,
with fewer cones in their retinas, but better night vision. Good human vision
is 20/20 but typical dog acuity is 20/75 – dog has to stand 20 feet away from
something a human can see at 75 feet. Near-sighted dogs have even worse visual
acuity; there is some variation by breed.
Most animals have panoramic
vision and can be distracted by what is behind them. They do have some
binocular vision for sense of depth. Human retina has a fovea – round spot of
best vision. Animals from open habitats (cats, dogs, cattle) have a visual
streak. Animals lowering their heads as bulls do before charging, or sheepdogs
before herding, are probably lining up the image on their visual streak.
‘Visual cliff’ is common to
people and animals and seems to be an inbuilt signal of danger. A dark colour
on the ground is interpreted as being deep – babies won’t crawl over it.
Animals have better contrast vision so may see it as a false visual cliff – as
with cattle grids. A poor man’s cattle grid is to paint bright white lines
across a road – the contrast is enough to deter cattle unless highly motivated
(mother separated from baby, much better grazing); however, once crossed they
learn it is not a danger. Completely colour-blind people are better at
interpreting reconnaissance photos.
Colour
vision varies among species.
Birds:
ultraviolet, blue, green, red.
Humans, some
primates: blue, green, red.
Most mammals: blue, green. (see
best a greenish (safety vest) yellow and a bluish (purple iris) purple.
Sharp contrast draws the
attention of an animal and either distracts or scares – but novelty is the real
issue, even for an item seen before in a different context. On their own, they
will investigate a novel stimulus but not if it is forced on them – curiosity
means they can pick up danger signs in their environment. They are less scared
of people lying down.
Animals also react to rapid
movement – prey animals run away, predators chase. Novel high-pitched sounds
will cause cattle to baulk as they activate the part of the brain that responds
to distress calls. Intermittent sounds are worst – can’t relax as waiting for
next sound.
Brain is layered. The reptilian
brain (the oldest part) = basic life support, the Pleomammalian brain =
emotion. Neomammalian brain = reason and language. Humans have much the biggest
neocortex; they generalize from one situation to another, animals far less. Dogs
must be trained to same task at both class and home.
TG speculates that developmental
disorders happen less in animals as their frontal lobes are less well
developed. Frontal lobe functions are the first to go, whether from traumatic
head injury, developmental disability, old age or even lack of sleep, perhaps
because other part of the brain connects to the frontal lobes, so any brain damage
can present as frontal lobe damage. TG notes that autistics have normal frontal
lobes but imperfect input to the lobes.
Evolution works on the use it or
lose it principle, but if not important for survival or reproduction, weak or
defective genes can be passed on. Fixed action patterns (rooster courtship
dance, hens receptive position) can be disrupted by single trait breeding,
which can have unexpected effects on other areas.
Pure white (albino) animals and
humans have more neurological problems. Dalmation dogs are closest to albinism,
more likely to be deaf and ‘airheads’; collies bred for narrow heads, less
brain room so less intelligent; labradors are opportunistic eaters, always
hungry, and notorious chewers – maybe a side effect of breeding for calm
temperament. Colour of skin more important than colour of fur. Albino rats are
perhaps not best for drug research (though typical) as melanin binds to some
chemicals. ‘White’ humans evolved and are not albino.
Owners tolerate worse behaviour
in purebreds; in USA, purebreds are responsible for c.74% of all fatal attacks
on people. Genetically dogs are juvenile wolves; they stop developing
emotionally and behaviourally at the wolf puppy equivalent of 30 days.
Children’s frontal lobes are
still growing and don’t mature until early adulthood; their emotions are more
straightforward than adults’. Autistics have decreased connectivity in the
cortical regions and between cortex and sub-cortex.
Normal people suppress bad
memories in their unconscious (verbal overshadowing) but autistics recall
everything (so can’t watch violent movies). Language seems to act as a filter.
Interest, curiosity, anticipation
– primary emotion, the ‘seeking’ circuit. Some evidence that drugs (e.g.
cocaine) stimulate this not the pleasure centre. Humans enjoy any kind of hunt
(collecting, finding facts, searching for the meaning of life in church or
philosophy seminar). The ‘seeking’ circuit fires when searching for food but
stops when eating – this explains novelty seeking. Animals prefer new toys
initially, even if in poorer condition or less interesting than old toys.
Children are the same with toys, adults with clothes, cars, etc. Newness is
pleasurable.
Normal people use different parts
of the brain to recognize an object versus a face. Autistics use the object
recognition area for both faces and objects.
Autistics tend to have extreme
sense perceptions (hearing and seeing things that others do not) as well as
being super-sensitive to sensations. All children need to be touched but autistic
children feel over-whelmed by normal touching and have to be de-sensitized. Rock
& Mack think the brain does a lot of processing before allowing something
into the consciousness – explaining visual inattention and implicit cognition
(subliminal perception). Locomotor play seems to help brain development (cf.
effect of too much tv watching, computer game playing?).
Need to socialize dogs not just
to own toddlers but also to other peoples – dogs don’t generalize. No domestic
animal should be reared in isolation. Pet owners need to socialize new kittens
and puppies not long after they bring them home. In the wild, animals are free
to come and go, socialize with other local animals; dogs kept in gardens and
only out on a leash prevents proper hierarchy establishment. Dog owners must
establish themselves as the alpha animal. Make rolling on to his back
(submissive position) fun –stroke chest or belly fur. Enter the house first,
put hand in feeding bowl while he’s eating. Working dogs should not be bought
as pets.
All animals, but especially prey
animals, mask pain unless alone. Pain is a frontal lobe activity; since animals
have smaller frontal lobes, it is likely they experience less pain or are less
upset by the pain. Insensitivity to pain (and cold) is on the checklist of
symptoms for autism.
Animals and humans learn some fears
(e.g. of snakes) from others. Such learning, like any intensely emotional
learning is permanent; procedural learning (riding a bicycle) also seems to be
permanent but not observational learning. Animals and humans can get over a
learned fear but never forget it.
Slow fear: scary stimulus to
thalamus (base of brain) for analysis – identify snake – amygdala – feel afraid
[24 secs]. Fast fear: stimulus straight to amygdala – feel afraid [12 secs]. Operate
simultaneously: fast fear is the quick and dirty route getting you out of likely
danger quickly, slow fear is the precision route.
Gifted
children perform well on multi-faceted (multi-component) tasks.
Single:
choose blue one from coloured squares.
Double:
green dog not green cat or red dog.
Triple: big
polka-dot circle.
Four: big bear and little square.
Gifted children can do this at age 3, average at age 6.
Early human / wolf association;
humans seem to have learned wolf behaviours (not exhibited by any other
primate) such as loyal same-sex and non-kin friendships, highly territorial,
hunting in groups, complex social structures. Fossil records show that whenever
a species becomes domesticated, its brain gets smaller. That of the horse
shrank by 16%, pigs by 34% and dogs by 10% - 30%. Humans may have been
‘domesticated’ by dogs as the human brain shrank by 10% at the point they
started burying their dogs. In all domestic animals, the forebrain and the
linking tissue in the corpus callosum shrank, but in humans the mid-brain
(emotions and sensory data) and olfactory bulbs (smell) got smaller. It seems
that humans took on the planning and organizational roles and dogs the sensory
tasks in the partnership.
Animal welfare regulators tend to
draw up long checklists of problems / violations. TG advocates setting high
standards (works better than zero toleration) and correcting all problems.
TG identified 5 key measures for
abbatoirs, etc., each with a compliance level (100%, 97%, etc.). For example, 5
acts of abuse means automatic failure on that measure. However, each key
measure can be caused by a variety of things (which will all need to be
rectified), but for the actual audit only 5 factors need be measured.
