• Being a “space invader”
• Staring into lights
• Self-stimming, such as rocking, spinning, banging head, humming, or screaming
• Little or no eye contact
• Picky eater (especially regarding textured foods)

Does your child display any of these “odd” behaviors? What we see as abnormal or sometimes even impish or difficult is usually related to the child’s attempt to calm their body or make sense of their environment through the sensory input they receive.

It has been documented that many children with ASD have difficulty processing sensory input. Normal sensory integration is taking information from your surroundings through your senses and sensory systems, including sight, smell, sound, touch, and spatial awareness (where your body ends and space begins). The information is processed in the brain and then interpreted, organized, and sent back to the body with instructions for an appropriate response.

What happens when it goes wrong?

Imagine being “under assault” by your senses 24 hours a day. In children whose sensory systems are not properly developed, this is what it’s like. Having a sensory processing disorder means you collect the input like anyone else, but when the data enters the brain it is not processed correctly and therefore the brain sends out inappropriate and abnormal responses.

Hyperesponsive is when the brain essentially short circuits from magnified or intense sensations. Even the lightest touch to a child can trigger a “fight or flight” response: the nervous system is perpetually on high alert and perceives nearly every movement or sensation as danger. Because of this, the child may avoid certain foods, clothing, movements, or perform repeated movements in attempt to calm the body.

Conversely, hyporesponsive is when the brain simply doesn’t register and respond to input received. A child may fall down or bang his or her head and not indicate any sensation of pain. In effort to make sense of their world, they may employ all other senses to compensate. A hyporesponsive child may not be able to tell if they are sitting straight in a chair or falling over. Imagine! They will also constantly touch walls, lean back in their chair, or feel countertops and surfaces to try and ground themselves.

What if I relate to both types?

You probably are saying to yourself that your child exhibits behaviors from both categories. Me, too! Most children with a sensory processing disorder are actually hyporesponsive to some input and hypereponsive to other types. For instance, if proprioceptive input is needed by the body they may jump or push things; if for vestibular input they may spin or rock, and for tactile input they might crave deep pressure. They also lack the ability to separate their experience/input from yours, so they will frequently do to others what their bodies are seeking (squeezing the dog, plowing into a parent holding hot coffee…).

Awareness and compassion – the first step

The bottom line is that children with sensory dysfunction cannot learn to function within their daily routine unless their surroundings make sense. To compensate, the brain either turns up or turns down the response, which results in the behaviors described above.

I have found that this kind of awareness can instantly turn my frustration into compassion when dealing with these behaviors. It also helps me help my son by recognizing the responses and asking him the right questions. This encourages him to describe what he is experiencing and teaches him to ask for what his body needs before it spins out of control.
