Appendix IV
Troubleshooting perceptual sensitivity

In Chapter 17 (Growing perceptual sensitivity) I made a firm link between difficulties with perceptual sensitivity and insecure attachment; however, insecure attachment isn’t the only reason for such difficulties. Some children who are securely attached still have difficulties with their senses. This was something originally identified by occupational therapist Dr Jean Ayres. She found there to be three groups of children whose sensory perceptions were faulty in quite different ways.

Best known are the children for whom the world is brighter, louder, busier, harder, sharper, steeper and smellier. It is hard to regulate yourself if that is your world. It is hard for parents to feel confident when handling or playing with such a baby. In fact, the biggest impact this kind of sensory difficulty may have is that the bond between parent and child is damaged. These children have a ‘defensive’ response to stimulation.

Often these defensive children grow into children other people describe as ‘difficult’ or as a ‘Mummy’s boy or girl’ or ‘with poor social skills’. Only their parents know a very different child because, at home, these children don’t need to defend themselves against unexpected sensations. But away from their home, life can be very hard. I remember hearing of the behaviour of one poor little boy who had an over-the-top defensive reaction to sound at his end of year concert. As the rest of his class played their recorders he clapped his hands over his ears and screamed, ‘No, no, no!’ A family friend heard the story, suggested an occupational therapist and he is now finding life far more bearable.

The second group of children, and I don’t think I know a child like this so this description is drawn purely from my research into the subject, have the signals from the world outside mixed in with some internal neurological ‘white noise’ of their own. It’s hard to make sense of a world like that, or to know if you can trust what your senses are telling you.

Finally, there is another group of children who register far less than most of us of the world around them. Touch is softer, sounds are less exciting. These are sometimes the ‘easy’ babies who show a slower developmental rate as there is simply not quite enough information flowing in to grow their brains at normal rates. These children are described as ‘sensorily dormant’. These are children who are ‘surprise’ referrals to occupational therapy at the end of the school year. They are so very compliant in the classroom that it is only when the teacher does her end of year testing that she discovers how little they have learned. These children often have lower muscle tone and less expressive, ‘softer’ faces.

Before starting off exploring the world of the child for whom sensations have unpleasant intensity have some strong coffee. Put on some very warm, scratchy clothes that don’t fit you comfortably. Play some music that you don’t like and turn it up too loud. Make the room too bright. Spray some nasty smelling insect repellent around. Quickly throw some objects on the floor and muss any surfaces if you like things to be neat. Now try rocking forward on your toes and imagining yourself looking down to the floor and finding it a bit further away than you had thought. For these children the world is surreal, disorientating and exhausting; and touch, which usually brings such emotional comfort, is emotionally disruptive. This is the most involved case scenario, a child with most senses switched on to ‘extreme’ sensitivity. For some children just one sense may be affected, while for others it’s a small cluster.

Now imagine a world with far less sensation. It is a dreamier place. Imagine a badly managed day spa with rather cloying scents, where the music is bland and too soft, and the masseur doesn’t ever get to the really sore spots. It’s much harder to feel really alert, really energised or engaged, satisfied and successful. And this is the world inhabited by the children who have only a poor registration of sensation.

The hardest world of all to imagine is the world where children have white noise from their own brain leaking into the sensation coming in from the outside world. I guess it would be like living with a waterfall or a freeway in your head. If you suspect this is the case for your child, I’d recommend seeking specialist attention.

In addition to the bombardment or ‘underwhelmed’ state of their senses, these children also experience great fluctuations in how their senses respond: good days, okay days, bad days. This makes an already difficult situation worse. If you are missing an eye you learn to compensate. But if you have an eye that works some of the time, to no particular pattern, it’s much harder to develop a way of compensating.

So why do these fluctuations in sensory receptiveness occur? And how can parents help children for whom this is an issue? There won’t be ‘no reason at all’, but it might take some figuring out. What we do know is that everyone ‘spirals down’ to a lower level of function under stress. Stress tends to show up first wherever we are already weakest. For these children this is in their brain’s ability to understand sensation. And just about any kind of stress can be responsible. The wrong food, not enough sleep, a growth spurt, a distressing failure, a nasty additive, fighting off a tummy bug: many possibilities must be sifted through to find the reasons for bad days.

Perceptual sensitivity and difficulties with behaviour, attention and learning

Children with both a dormant and defensive response are going to have difficulties learning, attending and behaving. Take the following example of Andrew and Lila.

Four-year-old Andrew screams when he is pushed out of the way by three-year-old Lila. She is running around seeming not to notice the nasty gash on her knee. Observers are all too likely to conclude from watching that Andrew is a ‘wuss’ and that Lila is ‘tough’. And it won’t take long before Andrew and Lila apply those labels to themselves. Working out that sensations differ from person to person requires theory of mind that is beyond most young children, and it is something that some adults have difficulty accepting too.

In fact, what is happening with Andrew is that he can’t make sense of the information coming in from his touch sense. It all feels angry and aggressive and meaningless to him. So he does everything he can to defend himself from experiencing even moderate amounts of tactile information. He’s picky about his clothes: anything textured is experienced by him as rough and scratchy. He washes his hands and face between bites of his honey sandwich as he experiences stickiness as unpleasant and intrusive.

The extra sensory load that Andrew has to deal with means that he has been a poor sleeper since infancy. Even now, every single night, his exhausted parents are unwillingly reminded of the princess and the pea as Andrew finds blankets, sheets, pillow and even his pyjamas can keep him awake or, on bad nights, wake him up.

Generally, an area of discomfort slowly intrudes upon our attention. But Andrew is simply not able to organise touch information into what is important and what isn’t important. He can’t switch any of it off. And because he isn’t able to do that, he has great difficulty learning from his touch sense. Learning to write is going to be very difficult for Andrew as he won’t like to hold a pencil. His parents are dreading the start of school on his behalf as he spends all his time around other kids trying to avoid being touched by them.

Empathising with the sensorily disordered child

It is just so important to get inside your child’s skin if he fits one of these profiles. Without this understanding it’s all too easy to conclude that your child doesn’t like you very much. Such a child might push away a loving hand, cry at the sound of your voice or fail to realise that he has hurt you as he pushes rapidly past. Once in his skin, you can see the vast gulf between the world he perceives and your own, and you can set out to help him normalise his perceptions.

Learning to write is going to be difficult for Lila too, but for the opposite reason. In marked contrast to Andrew, Lila was a good sleeper and pretty much an all-round easy baby. (The words ‘easy baby’ are sometimes a red flag.) She has always amused her parents by her complete obliviousness to temperature. In summer she likes to wear her bright pink gumboots. In winter she would run around naked if she was allowed to. Recently, however, her parents have noticed that she’s rough with other children and animals. She has taken to throwing herself off the bed onto the floor. Even though Lila giggles when she lands, it looks painful to her mum and dad. What’s happening? Lila is beginning to crave much more intense tactile stimulation: her brain is literally starving for sensation.

Her parents are already worrying about her fine motor skills. They have noticed that she has real difficulty doing puzzles that her little sister of two is able to easily complete. Why? Her hands aren’t able to move precisely because she can’t obtain precise sensation from them. She is turning into what therapists call a ‘sensory seeker’. This is a good sign, actually, as Lila is seeking to normalise her dormant tactile system all by herself.

Andrew’s dad is trying to normalise his response to touch by touching Andrew more and ‘getting him used to it’. He wakes him up by tickling him. He lightly messes his hair. Andrew giggles, but also begs his dad to stop. His dad is away for a week, and when he returns his mum says that this has been a much better week for Andrew. He has slept better. He tolerated a smear of honey on his arm while eating a sandwich. He spent a whole hour with his train set by himself.29

The tickling games were triggering a defensive response early in the day, and in their absence, Andrew had a calmer base from which to explore. When Andrew’s dad asks him what games he would like to play, Andrew announces that he would like to be squashed. And deep pressure does have the effect of normalising the tactile system: light touch is stimulating, heavy touch is soothing.

The older Lila’s sister gets, the more Lila’s mum realises something is not right with Lila. Her most recent discovery is that she doesn’t notice odours. Her mother decided to try to get Lila to tell the difference between different smells. By dabbing different smells onto cotton wool she made up a smell box for Lila to try and pick out different smells. Lila couldn’t smell anything on the cotton wool. Her mother then added different essential oils to the floor of the shower every night: eucalyptus, spearmint, orange. Within a week Lila was saying that the smell was, ‘A bit strong’. Soon afterwards, she found Lila ‘feeling’ different textures with her face. Often the olfactory or smell sense has to come online before the other senses wake up.

The ways that Lila and Andrew behave, although likely to impress the observer as ‘poorly parented’ or ‘naughty’, are only to be expected in children with perceptual difficulties. For Andrew touch information is so overwhelming that it amounts to torture; for Lila, even quite strong sensation is barely registering. And the same child can have both experiences in different sensory domains.

Listed below are questions to help you identify if your child has difficulties organising or receiving sensory information. The questions begin at the infant or baby stage and move on to older children.

Vestibular (the sense of where you are in space) system

Defensiveness:

Dormancy:

Visual system (the visual and vestibular systems co-develop to a great degree)

Defensiveness:

Dormancy:

Olfactory (smell, and to some degree taste) system

Defensiveness:

Dormancy:

Tactile (the touch sense) system

Research shows that parents often underestimate their child’s degree of tactile defensiveness. If your child is old enough and you think this may be a concern, you might like to ask him how touch affects him.32

Defensiveness:

Dormancy:

Auditory (hearing) system

Defensiveness:

Dormancy:

Proprioceptive (the internal ‘movement sense’ — knowing where your body parts are in relation to each other without looking) system

Defensiveness:

Dormancy:

What you can do to help

Sensory systems can be normalised. Even when therapists are involved it is parents who do most of the work. In fact, the work of therapy sometimes builds a bridge between parent and child, and in such cases it is the repaired relationship that may make the biggest contribution to a child’s better sensory perceptual skills. It certainly stands up to examination when you consider the mother’s role in building her baby’s perceptual skills in the first place.

Start by observing your child. What always gets his attention? Is it the ticking clock, the bird flying past, the smell of food? What kind of sensory information most destabilises him? This is likely to be his most ‘hyperactive sense’, and the one you need to be most wary of overloading. What kind of information is he most likely to miss: smells, tastes, sights or sounds? What information does he process most easily? Once this is identified you can work from this strength. The senses feed each other confirmatory information, so the strongest sense can be used to help organise any sense that might be dormant (under-active) or defensive (far too active).

Observe what your child does to calm himself down and which sense he uses to do it, particularly at the end of a school day. Does he move, does he sit and read a book, does he sing or talk to himself? Equally, observe what he does to ‘ready himself for action’, to focus better. Never intrude on such times as he is building self-regulation skills. Make a mental note so that you can ‘scaffold’ him by providing such time regularly in his day. Just as for babies, it’s important for brain growth that your child spends most of his day ‘well-regulated’ rather than dysregulated (feeling ‘out of kilter’ both emotionally and physically).

With this information, deliberately set out to engage with your child as closely as you can. If you have a ‘defensive’ child and you are a spontaneous and exciting kind of parent, this may mean changing your way of relating to him. These children need predictability, slower movements, softer, slower voices. Shouting at an auditory defensive child, for example, is going to distress him rather than help him to comply. Most mothers with children like this actually use soft, almost whispery voices. In general, these children need just ‘one channel of information’ to be stimulated at a time, so try to avoid moving, touching him and talking all at once. Your overall goal is to ‘dampen down’ his need to defend himself against the world, to help him reduce his need to defend himself so he can open up enough to take in information and begin to organise it.

Some gifted children also present very similarly to the defensive child, and, of course, there is going to be some crossover. Children do not fit into neat categories. (There is an excellent free internet resource on giftedness. Type GERRIC into your search engine and then choose the DEEWR Professional Development Package for Teachers.)

The creative or gifted child who displays Dubrowski’s ‘over-excitabilities’ — the hallmarks of giftedness involving talking at a great speed, jiggling madly with excitement, imagining whole forests of wild ideas — is equally likely to feel bombarded by sensory stimulation. This is not due to problems with sensory perception but from a heightened response to what they perceive. The environmental management ideas discussed below may be useful for helping gifted and creative children, but it is important to recognise that for these children this ‘over-excitability’ is part and parcel of their temperament. Help them find ways to order and use sensory information, but also accept that they will still whirl like a dervish when a new dinosaur is discovered.33

Defensive behaviours are also a feature of autism. If a child shows these defensive responses to sensations and also is not responding to his name or responding to your emotions and prefers objects to people then you need to suspect autism and get a professional opinion very quickly. (If you’ve read the description of the development of empathy and theory of mind in parts Two and Four, and thought, ‘This isn’t my child’, again, I would recommend a visit to a paediatrician.) Early intervention with autistic children helps tremendously.34

If you have a child who fits the ‘dormant’ profile most of the time, and your own style is equally low key, you may need to develop a higher energy way of relating to wake him up to the world. You may find that he has one sensory channel that is more alerting, and you can use this to prompt him into really paying attention.

And from there you can begin playing the kind of games that help normalise sensory systems. The rules are simple: make sure it is fun and follow your child’s lead. Never push; never force. When a parent pushes a child and they become overwhelmed by sensory information it is not just bad for the relationship, but for the child’s growing brain. And to speed up learning, it has to be fun. Keep the oxytocin flowing with lots of laughter.

The ideas listed in the following pages are intended to be a general guide and a good starting point. Once you know what you are looking for you will find that together you and your child generate the most satisfying and therapeutic games.

Vestibular system

Start by checking whether your child has a physical problem such as an ear infection, because the vestibular nerve runs through the ear. Play games that build the vestibular system: rocking, rolling, twirling. The same games are used to ‘normalise’ sensation in dormancy and defensiveness.

How do you know it is working?

Initially there may be a brief regression to younger behaviour. You will know things are getting better when you see the flicker of nystagmus (eyes keep moving after the spinning has stopped) starting; and when the child takes over the therapy and spins, climbs, rocks and takes ‘balance risks’ of his own accord.

Visual system

How do you know it is working?

You will feel that your child is paying far more attention to you and that you are more strongly and deeply connected to him. You will also see an improvement in his length of attention.

Olfactory system

How do you know it’s working?

The dormant child will become aware of smells and the defensive child will not be so affronted by them. But you should also see improvements to his tactile and auditory sensory issues.

Tactile system

How do you know it is working?

As the touch system normalises children ‘stuff in’ as many tactile experiences as they can, just in the same way the eight month old does. It’s catch-up time! You may also notice changes to the way the child relates to others. For example, it can be a time of upheaval in class pecking orders (and even within families) as the child is more able to claim ‘equal rights’ with other children.

Auditory system

How do you know it is working?

As your child improves his auditory skills, he will begin to use them in everyday life. He will refer to his favourite stories and music. In independent play he will begin to make more of the zooming and brooming noises and also ‘voices’ for his toys. He will be able to remember and act on more of what you say.

Proprioceptive system

How do you know if it is helping?

Your child will begin to seem a lot more comfortable in his skin and, as a result, in himself. Rather than missing many environmental cues, or being made timid by them, his movements will seem less at odds with the events around him.
