Do you have a child who loves to crash, jump, bump, run, whirl and spin? A child who simply WILL NOT sit still?! Chances are you have a “sensory seeker”! Or do you instead have a child who is very “laid back,” sluggish, sedentary, tends to be a t.v./computer kid? In that case, chances are good you have a passive “under-responder.”
Often, when we think about Sensory Processing Disorder (SPD), we tend to think of the kids who can’t stand tags in their shirts, children who are picky eaters, or kids with motion sensitivity. These are signs of over-responsiveness to sensory input and while this is definitely one type of SPD, we cannot ignore their under-responsive peers.
When we are talking about over- and under-responsivity to sensory input, we are really talking about the specific skill of sensory modulation – the ability to make sense of sensory input and respond to it appropriately in order to stay organized and focused. Sensory modulation difficulties fall under the umbrella diagnosis of Sensory Processing Disorder.
What is Sensory Modulation (a.k.a. Sensory Regulation)?
As this graphic shows, over-responders are at one end of the continuum. These kids are the ones who are bothered by everyday sensory input. At the other end of the continuum, we actually have two types of under-responsiveness. One type, our “passive under-responders” are the ones who need more sensory input than what they are getting but they tend to gravitate toward passive forms of sensory input and therefore often seem not to be fully engaged in their surroundings. These kids may appear to be day-dreamers and may have difficulty learning because information isn’t being processed as quickly as it should be.
What can we do for our Under-Responders?
It is helpful to remember that both our passive under-responders as well as our sensory seekers have the same underlying issues and actually they have the same treatment needs. So what is it that they need? MORE sensory input! Ideally, they will have access to the intense forms of input that will be the most beneficial for their sensory systems.
Our goal will be to satiate that need for input so then their brains will be free to focus on other things (academics, etc.) for a reasonable amount of time. For kids who need to move, we want to build extra movement into their routines. Other kids may need opportunities for intense tastes or smells. Still others may need lots of deep pressure and heavy work opportunities. We often call the combination of these strategies that meet a child’s needs a “sensory diet.” Consult an occupational therapist to help you figure out what types of sensory input will be the most meaningful for your kids with sensory under-responsivity.
What about kids who are a little of both – UNDER- and OVER-responsive?
This is actually quite common. Very few people are either OVER and/or UNDER-responsive to every type of sensory input. Most of us are a combination of over-responsiveness to two or three types of sensory input and under-responsiveness to two or three other forms of sensory input. Our sensory needs also vary from day-to-day depending on what else is going on in our lives – pain, stress, fatigue, etc.
Therefore, be prepared to be flexible with your child’s sensory diet and offer a variety of sensory strategies depending on what their needs are on that particular day. Again, this process can seem overwhelming at first and you will fare better with the support of an occupational therapist to guide you as you begin the process of helping your child learn to self-regulate.
