Rethinking Behaviour in the Classroom: Understanding the Child with Sensory Integration Disorder Paula Aquilla (Occupational Therapist) Isabel Killoran (Professor, Faculty of Education, York University) Introductions: Hi. I’m Paula. I’m an occupational therapist. I have specialized in pediatrics, specifically in sensory processing. I am here to share information about sensory processing difficulties in their students so that teachers can recognize it in the classroom and accommodate their students’ needs accordingly. I’m Isabel. Currently I am a professor at the faculty of education at York University. Formerly, I was a teacher with the Etobicoke and Toronto Catholic Boards of Education where I came across many students who had sensory processing difficulties. I believe that addressing sensory processing in the classroom will help teachers manage their classrooms more effectively, while better meeting the needs of their students. What is Sensory Processing? Sensory Integration is a function of our central nervous system and it is the process of taking in, sorting and interpreting sensory information for functional use. Sensory processing is the ability to take in sensory information through each of our senses and process that information so that meaning can be given to it. Sensory processing takes place in our brain stem; a part of the central nervous system that sits under our brain and behind our nose. Sensory information travels from the brain stem to the brain itself where meaning is attached to the sensation and motor memories are stored. The ability to process sensory information is vital to our function and our interaction with the world. When we think of senses, we think about touch, vision, hearing, smell and taste. We also have two hidden senses which are less known. These senses are our vestibular sense, our sense of balance and our proprioceptive sense, the ability to know the position of our body. We process sensation from within our body and from the environment every minute of every day. We even process sensation during our sleep. When sensory processing isn’t efficient, our function, social interaction, learning and the ability to keep ourselves in a ‘calm alert state’ can reflect our difficulty. Dr. Jean Ayres was a talented occupational therapist from California who first introduced us to the term ‘sensory integration’. Dr. Ayres worked with children and was motivated to discover the ‘why’ behind some of the behaviours she was seeing in her practice. She researched and developed the first assessment to measure sensory integration; The Southern California Sensory Integration Test. Many dedicated and talented OTs have followed in Dr. Ayres’ footsteps and have contributed to our present understanding of sensory processing. Difficulties with processing sensory information can be divided into categories according to the most recent research: 1. Sensory Modulation Dysfunction – an extreme over or under responsiveness to sensations -children may have difficulty controlling their own response to sensation -response largely depends on the state of their nervous system -in sensory undersensitivity, the child has poor awareness of sensory stimuli -may be ‘loose and floppy’ with their bodies and have poor postural control -may excessively seek out sensation -may have a poor perception of pain and therefore poor self protection -in sensory oversensitivity, the child can have an extreme reaction to sensations that we hardly feel -may have a limited repertoire of clothing they can wear, food they can tolerate -may be fearful of balance related activities -may be extremely sensitive to sights, sounds, smells or tastes 2. Sensory Discrimination Dysfunction – this child can have difficulty differentiating among and between stimuli -can lead to difficulty in using sensory information to judge the value of objects, movements, sounds, sights, distance -difficulty making adaptive, meaningful responses 3. Sensory Based Movement Disorder – we can divide this category into two sections: a) sensory based postural disorder – child has difficulty aligning his/her body with respect to another person or activity -difficulty maintaining posture, being comfortable in balance and transitional movements b) sensory based dyspraxia -this child may have difficulty creating, planning and carrying our an unfamiliar motor action or a sequence of motor actions -can interfere with motor co-ordination and create disorganization, delayed responses and unsuccessful movements Sensory processing includes the ability to detect sensation, take it in with the correct amount of attention, and attach meaning to it. Sensory integration enables us to process more than one sensation at a time to give us a complete picture. This function involves all levels of the central nervous system. Some children have a diagnosis of sensory processing disorder. Many other children may have some symptoms of sensory processing disorder that are not consistent; rather they reflect the state of their nervous system. Why is understanding sensory processing important for teachers? Although this module is placed under special education, sensory processing difficulties can affect all children regardless of diagnosis. Recent research has shown sensory processing difficulties to be attached to anxiety, a much more common occurrence in our fast-paced, over-scheduled world. Without an awareness of sensory processing, many teachers can blame children for behaviours that they have little control over. If a teacher incorporates sensory processing when they are setting-up their classroom and planning their lessons (using a universal design framework; see Education for All document) Who may be the children in your class experiencing behaviour problems due to sensory processing difficulties? Children with Autism spectrum disorder Attention deficit hyperactivity disorder Cerebral Palsy Learning disability Hearing Impairment Visual impairment Anxiety disorder Children who have experienced trauma Children who have been institutionalized 5 – 10% of children without a specific diagnosis Statistically, you can expect to have more than child who would benefit from incorporating sensory processing principles into the classroom environment. What are some classroom challenges for a child with sensory processing disorder? Children with sensory processing disorders can find the classroom a particularly challenging environment. Some may find it too bright, too noisy, too hot, too cluttered, too close, etc. They may exhibit some of the following: -poor posture -withdrawal -difficulty with transitions -difficulty maintaining attention -difficulty sitting at a desk -trouble looking at the board and back at their paper -difficulty holding a pencil/pen -difficulty stabilizing the paper with the other hand -difficulty maintaining behaviour -trouble interaction with peers -seems disorganized in their work -appears to be unaware of the environment -limited participation in activities; especially new ones The list is long, but with creativity and problem solving, we can support the child with sensory processing disorder in the classroom. Paula and I have several video clips to help demonstrate sensory processing difficulties. We will focus on tactile defensiveness, posture and body awareness. When you observe the clips think of the students in your class. Does anything look familiar? Tactile defensiveness: Clip 1 Erin (JK) banged her elbow a few minutes earlier – it is just registering. Cherie rubs it which she allows her to do but notice how she pulls it away – it’s very subtle but we have to look for those clues – if we miss them or take them personally as a type of rejection then things escalate. Clip 2 Ella hands paper to Katie and it touches Katie’s hand. Katie’s response is hyper sensitive. In a classroom, this student could become disruptive and confrontational with peers. Often these students feel isolated and misunderstood. Clip 3 In this clip Erin demonstrates a need for a change in activity and stimulation. She’s been working quietly on the lite brite and then starts to reach out and poke Cherie – I’m sure you see this often in your classes, especially in circles and groups – so and so touched me; he poked me etc. Notice how Erin tries to engage Cherie in physical activity to meet her own need for touch (a hypo sensitivity) – Cherie recognizes it and tickles her; Erin flops again and then goes back to lite brite – a very brief break but if not planned in a classroom it could become quite disruptive to a lesson and to peers. Also notice, that in the earlier clip Erin demonstrated a hypersensitive response. This inconsistency is common with children who have sensory processing disorder. Posture: Clip 4 In these two segments you will observe Katie and Ella struggling to maintain their posture and attention to the task. They don’t have an automatic knowledge of their body position in space. Clip 5 In this clip, notice the awkward changing of position – Erin knows Cherie is too close but instead of getting up and sitting down on floor or moving her chair she turns her back and leans over to do her work on the floor – then flops onto the floor to do the work – it’s a good thing she recognized that she didn’t want to be that close to Cherie – we must allow kids to find the positions and places they are most comfortable and productive in – it is not always at a desk. Body Awareness: This really goes hand in hand with posture. These students don’t seem know where their body ends and the world begins. You will notice them crashing in to people and things, walking down the halls touching the walls, and they don’t seem to have an awareness of the personal space of others. Clip 6 Ella bumps into Katie and then the desk. There is no grading of movement. Everything is one size – large! These students have difficulty grading their voice, their movements and their contact. What can you do in the classroom? An approach which includes environment, teaching style and specific activities, like a sensory diet can help a child with sensory processing disorder and support success in the classroom. A sensory diet is an intervention approach or strategy that is designed to meet a child’s individual sensory needs to facilitate their ability to maintain a calm alert state. Just as a food diet includes the right type and right amount of food to maintain health, a sensory diet includes the right type and right amount of sensation to maintain the nervous system in a calm, organized state. Many occupational therapists have contributed to our current understanding of sensory diet. Patricia Wilbarger created the term ‘sensory diet’ and Bonnie Hanshu has contributed to our understanding of what happens on a neurochemical basis when we receive certain types of sensation. We all use sensory strategies regularly throughout the day; sipping on our water bottle, doodling on our paper, twisting our hair and going for walks. Some children have difficulty processing the sensory input they receive from their environment and even from their own bodies. Difficulty processing sensory input can contribute to difficulty regulating their activity level, their mood and their behaviour. A sensory diet can help! A thorough assessment is essential to a custom fit sensory diet. Find out what the person likes to do; what interests them and holds their attention. Use a combination of information collecting strategies; formal assessments (The Sensory Profile by Winnie Dunn for example), informal assessments (sensory checklists), interview parents, teachers, day care providers and observation of the child in different environments. Gathering information on the amount of support a parent/teacher has, the support of the institution, the environment, the available equipment, time constraints and the needs/schedules of other siblings/students. It sounds like a lot of work, but the more research you do, the more ‘custom fit’ your sensory diet will be and the more successful the child will be. The success of the child is what it’s all about! Activities for a sensory diet can be scheduled at regular intervals throughout the day. For example, every time the student prepares for table work, they do 10 push ups off their seat. Sensory activities can be provided through daily routines; wearing a weighted knapsack in between classes. The environment can offer specific sensation, (rocking chair, natural spectrum lighting). Leisure and recreational activities can provide sensation that helps organization, (swimming, rock climbing, horse back riding). Our interaction with the child is also a source of sensory input, (our voice volume, our proximity). The environment, teaching style, and specific activities can contribute to a child’s ability to stay in the calm alert state and maximize learning. 1. The environment -is there space to move, a mini trampoline for the more active child? -is there an opportunity to integrate movement? -can children sit on movable surfaces to support their posture? -are there opportunities to try a table top slant board? Pencil grips? -can the student’s desk be adapted so that they can seek out sensory input without even getting up? -are the lights and sounds able to be adjusted? -is there a quiet area with quiet calming activities? -is there opportunities for adaptability for smell and taste sensations? -are figit toys available? -are weighted vests/compression vests available? 2. Teaching Style -how does this child take in sensation? How do they learn? -is the teacher’s voice be set for the pace and tone that the student can process best? -how close should the teacher stand in relation to this student? -which side does the student process information better? -what motivates this student? Can you use it? -if the student is sensitive to smell, consider this prior to using scented products -if the student is easily distracted by visual input, the teacher can consider this when putting on jewelry or choosing colours of clothing 3. Specific sensory activities -can sensory activities be available to this student? -can sensation be a part of the curriculum? (eg. smelly markers for colouring for the student who loves scent, no smelly markers near the student who is sensitive to smell) -can figit toys to used to help a student wait or to provide a focus during seated activities? -can an exercise program/yoga/tai chi be incorporated for the entire class? -can a sensory diet be used? Understanding sensory processing dysfunction can assist a teacher in supporting students with this disorder in the classroom setting. There is a ‘why’ behind behaviors and this theory does provide some of the answers. An occupational therapist can help design an environment, teaching style and specific activities/sensory diet to help students with sensory processing disorder maximize their learning. Attention to the student’s ability to process sensation facilitates learning as it helps to keep their nervous system in a calm alert state. Be creative when you create environments, teaching styles and sensory activities/sensory diets! Have fun meeting the sensory needs of your students and watch your students learn, grow and mature!
