Some people believe behavior analysts are “anti-sensory” — opposed to offering any sensory-based experience for individuals with autism spectrum disorder (ASD).  The term “sensory” can be problematic and ambiguous because it does not specify whether an individual is showing a sensory preference or sensory aversion, nor whether the sensory experience is a “like” or a “need.” It may also minimize or disregard other explanations for why a behavior is occurring. These distinctions are significant when developing a treatment plan. In this brief article, we clarify how behavior analysts approach sensory issues.

Not every behavior problem should be assumed to have a sensory basis.

It would be beneficial to discuss the many faces of motivation. Each of us, not just children with autism, may be highly motivated by sensory experiences that vary in modality, intensity, and duration. Ever catch yourself tapping your pencil, twiddling your thumbs, biting your nails, or popping bubble wrap. If so, would you say you have “sensory issues”?  We are all highly motivated by other experiences as well such as attention, a smile, a knowing look, or laughter. Other times, it is something tangible and specific, such as a new pair of sneakers or a piece of artwork. We all engage in a wide array of behaviors to access these experiences. On the flip side, sometimes we are motivated to avoid or escape certain forms of attention (e.g., closing our office door or ignoring telemarketer calls) or other specific things (e.g., a traffic ticket or non-preferred vegetables).  Why is this important?

First, assessment of challenging behavior must carefully assess the function for that behavior (i.e., underlying motivation) in order for it to have the greatest likelihood of leading to effective intervention. We intentionally referenced the same behavior (biting) in a few different examples to help make the distinction between form (e.g., biting) and function (e.g., to escape a demand of gain sensory input).

  • Tommy bites his teacher when she attempts to help him put on his snow boots.
  • Lisa bites her father as soon as he stops playing with her and attempts to leave the room to take a phone call.
  • Sudhir bites his babysitter when she asks him to put away his iPad.
  • Melanie bites classmates when the fire alarm sounds or her older sister plays music loudly.
  • Jennica bites her father’s arm when he wears long sleeve dress shirts.
  • Mitchell’s teeth are coming in and he has been seen biting a plastic hanger.

As you can see, the same behavior (biting) occurs in very different contexts and likely serves very different functions. In some instances, the motivation may be to get or keep a preferred item or activity, whereas in other instances, the child is trying to avoid or escape something he or she does not like. A “sensory” explanation based on the fact that they are biting would miss the mark in most of the examples illustrated above. If we mislabel certain behaviors as “sensory,” the recommended sensory intervention will not address the targeted behavior properly and may prevent access to more effective intervention.

Not every sensory-seeking behavior reflects a “need.”

Let’s examine the misuse of the term “sensory need” and differentiate between a sensory need and a sensory preference. Some individuals with autism enjoy swinging, may be willing to work hard to earn it and show pleasure while swinging. Whereas other children may start off agitated and appear calmer following swinging, but it is not necessarily an experience they would choose (children experiencing pain relief from taking aspirin may also benefit from it but not necessarily choose it).

Activities stimulating the senses can serve multiple behavioral functions, depending on the motivation. Jumping on a trampoline is likely to be repeated because of its reinforcing vestibular effects — it is fun. This leads to the question, “Does the student jump on the trampoline because he or she needs to jump on the trampoline, or because it’s enjoyable?” Again, the responses one engages in depend on the learning history, communication skills, social contingencies, and the strength of the motivation.      

“Sensory” concerns have profound implications for the teaching of new skills that can be targeted through behavior analytic strategies.

Any discussion on “sensory issues” would be remiss without some mention of sensory hypersensitivity. We have also observed some individuals with autism who have extreme reactions to sensory input (e.g., loud noises, bright lights) and there are those who are extra sensitive to textures or certain clothing (e.g., the tag in the back of a shirt or particular food). These children/adults learn to engage in behaviors that reduce the aversive nature of such stimulation. But this isn’t exclusive to autism – there are also people without autism who are sensitive to certain stimuli as well.

There are individuals who experience extreme discomfort when exposed to situations which would be considered typical to most of us (e.g., loud music). Some will engage in behaviors that relieve the anxiety, such as escape behaviors (leaving the situation), avoidance behaviors (skipping the situation entirely), or engaging in some incompatible behaviors (practicing relaxation techniques). In these cases, sophisticated skills and strategies are in place.

It is unfortunate that many people with autism do not have the skills to engage in the socially accepted methods that relieve anxiety or discomfort. However, many other non-socially accepted behaviors have been shaped and have proven to be effective in removing the aversive stimulation. If we were in a room where the music is too loud, we would leave or ask for it to be turned down. If those behaviors are not possible, we may have to tolerate the situation. We have learned that behaviors such as biting will result in undesired social consequences. But what if:

  • We did not have the language to ask for the music to be turned down?
  • We did not know that leaving was an option, or did not know how to ask, or were forced to stay?
  • We didn’t value the social consequences as others so? That is, we didn’t currently care how others perceive us or if we get invited back.

If all those were true, we might engage in biting to get the music turned off or get removed from the room once we see that this is an effective behavior.

Now, suppose we do have those skills, and we can always find a way to get out of situations that cause stress or sensory overload; or we tough it out because of the social contingencies that have been learned over our lifetime. Chances are, no one would suggest we had sensory issues and put us on a sensory diet or prescribe sensory integration therapy. However, a person with autism who may have the same level of discomfort and escapes the situation in the only way he or she knows how, is often said to have “sensory issues” when perhaps it would be more helpful to say he or she has skill deficits.

In summary, to develop the most appropriate and effective treatment, one must analyze the function, evaluate whether the behavior has a sensory basis (and whether it reflects a “need” or a “like”) or other underlying motivations. It is then important to identify skills (e.g., requesting) that may either compete with and potentially replace the behavior or provide the individual with coping skills to better negotiate his or her environment.
