1 The Sensory World

2 Sensory Integration Take in information Process the information Respond to the information

3 How our senses work Our central nervous system (brain) processes all the sensory information we receive and helps us to organize, prioritize, and understand the information. We then respond through thoughts, feelings, motor responses (behavior), or a combination of these.

4 Sensory Processing We have receptors all over our bodies that pick up sensory information or “stimuli”. Our hands and feet contain the most receptors. Most of the time we process sensory information automatically without needing to think about it.

5 Sensory Processing People or children with sensory integration difficulties have difficulty with processing or taking in the sensory information. People or children who struggle with all of this information can sometimes become stressed or anxious. They can also possibly feel pain or may exhibit challenging behavior.

6 Sensory Integration Sensory integration should be well integrated by 8-10 years of age.

7 How do I know if my child is having sensory processing difficulties? If your child is exhibiting behaviors or reacting to the extent that it is interfering with every day tasks or events. For example, you can’t give your child a bath or wash their face. You have a difficult time with putting clothes on them. Reactions or behaviors are extreme. For example, throwing themselves on the ground, covering their ears and running away. If your child is exhibiting the behavior across all settings. For example, covering their ears at a birthday party, at the gym, and when music is played. If your child is exhibiting behaviors in more than one area. Has a difficult time with loud noises, seeks all kinds of movement, and doesn’t like it when their hands get messy.

9 Our 7 Senses

10 7 Senses Sight Sound Touch Taste Smell Balance (Vestibular) Body Awareness (Proprioception)

11 Sight Our sight helps us define objects, people, colors, contrast and spatial boundaries. Sight helps us maintain our posture, define boundaries, and watch still or moving objects.

12 Sight Hypo (under-sensitive) Objects appear quite dark, or lose some of their features. Central vision is blurred and peripheral vision is sharp Central object can be magnified and peripheral is blurred. Poor depth perception- problems with throwing and catching; clumsiness Poor visual tracking Avoids looking at certain objects. Hyper (over-sensitive) Objects and bright lights can appear to jump around. Images may be incomplete. Easier to focus on details than the entire object. Eyes may tear up or appear red. Reacts adversely to bright light. Finger flaps in visual field. Stares at certain objects.

13 Sound This sense is the most commonly recognized form of sensory impairment. Hearing can affect someone’s ability to communicate and possibly also their balance.

14 Sound Hypo(under-responsive) May only hear sounds in one ear. May not acknowledge particular sounds Might enjoy crowded, noisy places or bang doors and objects. Difficulty with multi-step skills. Makes unusual or loud noises. Hyper (over-responsive) Noises can be magnified and sounds can be distorted and muddled. Particularly sensitive to sounds and may hear conversations in the distance. Inability to cut out sounds and background noise, which can lead to difficulties concentrating.

15 Touch Touch helps us to assess the environment we are in and we react accordingly. It also allows us to feel pain.

16 Touch Hypo (under responsive) Holds others tightly or give hugs. Walks with hands on the wall or furniture. Enjoys heavy objects on top of them such as blankets. Poor localization. Poor awareness of when nose or mouth is dirty. May not know when they have been hurt. Hyper (over responsive) Touch can be painful or uncomfortable. Dislikes having anything on hands or feet. Difficulty with brushing and washing their hair because their head is sensitive. Only likes certain types of clothing or textures. Has a hard time with standing between children in line. Picky eater.

17 Taste Receptors in our mouth tells us about different tastes; sweet, sour, and spicy. Taste is the weakest of the senses. Girls have move taste buds than boys.

18 Hypo (under responsive) Likes very spicy foods Eats everything-grass, Play- dough, non-food objects. May overstuff mouth. Hyper (over responsive) Has a restricted diet. Some flavors are too strong or overpowering because of sensitive taste buds. Certain textures can cause discomfort. Some may only eat smooth foods like mashed potatoes or ice-cream.

19 Smell Receptors in our nose tells us about smells in our immediate environment. Smell is the first sense we rely upon. Girls are more sensitive to smell.

20 Smell Some can fail to notice extreme odors, including own body odor. Some people may lick things to get a better sense of what they are. Examines items through smelling them. Inability to associate odors with memory. Hyper (over responsive) Smells can be intense and overpowering. Can dislike people with distinctive perfumes or shampoos. Hypo (under responsive)

21 Balance Balance is situated in the inner ear. This system helps us to maintain our balance and posture. It also helps us understand where and how fast our bodies are moving.

22 Balance Hypo (under responsive) May need to rock, swing, or spin to get inner ear input. Poor attention to task. Leans back in chair Bangs head Spins self in a circle. Makes frequent trips around the room or to the bathroom. Hyper (over responsive) Have difficulties with activities like sports, or where one needs to control their movements. Have difficulties with stopping quickly or during an activity. May get car sickness. Have difficulties where the head is not upright or feet are off the ground.

23 Body Awareness This sense is in the muscles and joints. The system tells us where our bodies are in space and how different our body parts are moving.

24 Body Awareness Hypo (under responsive) May stand too close to others because they can’t judge personal space. May have a hard time navigating rooms and avoiding obstructions. May bump into people or appear clumsy May grind teeth or chew inappropriate items. May bang head or overstuff mouth. Falls out of chair Hyper (over responsive) May have a difficult time with fine motor skills. For example, manipulating small objects like buttons or shoe laces. May move the whole body to look at something. Applies too much force on toys or pencils.

25 Ways to Help Small changes to the environment can make a big difference! Be Aware: look at the surroundings to see if it is creating difficulties for your child. Can you change it? Be Creative: Think of some positive sensory experiences. For example sledding or going to the park. Be Prepared: Forewarn your child about the possible sensory stimuli they may experience.

26 Sight Hypo (under-sensitive) Reduce fluorescent lighting- use deep colored light bulbs instead. Wear sunglasses. Use blackout curtains. Hyper (over-sensitive) Increase high contrast.

27 Sound Hypo Use visual support to back up verbal information. Hyper Shut doors and windows to reduce external sounds. Prepare your child prior to going to noisy or crowded places. Wear ear plugs. Listen to music.

28 Touch Hypo (under responsive) Use weighted blankets. Provide vibrating toys or massagers. Provide nontoxic, tot safe hand fidgets. Hyper (over responsive) Warn your child if you or someone are about to touch them. Remember that a hug may be painful rather than comforting. Gradually introduce different textures. Allow your child to complete or assist in activities themselves. (e.g.. Hair brushing and hands washing)

29 Taste As long as someone eats a bit of a varied diet, being hypo- responsive or hyper-responsive in this area may not necessarily be a problem. Consider eating in a quiet place rather than a noisy one. Gradually vary food temperatures. Offer assorted dips for finger foods. Find other times to play with food outside of mealtime (e.g. pudding or gelatin). Sneak fruits or vegetables into muffin mixes, pancake batter, or hamburgers. Try lots of foods that melt quickly in their mouth such as cheese curls or puffed cereals.

30 Smell Hypo (under responsive) Use strong smelling products to distract students from inappropriate smelling. Allow your tot to hold a scarf with your cologne. While traveling take time to stop and smell different items. Hyper (over responsive) Use unscented detergents or shampoos Avoid wearing perfume Make the environment as fragrance-free as possible.

31 Balance Hypo (under responsive) Encourage rocking, swings, and seesaws. Use toys that move or rotate. Play jumping or hopping games. Bounce on a ball. Hyper (over responsive) Break down activities into small more easily manageable steps. Jump on a trampoline Provide frequent movement breaks during sedentary activities. Dance

32 Body Awareness Hypo (under responsive) Position furniture around the edge of the room to make navigation easier. Use arm’s length rule to judge personal space. Carry heavy items (e.g. grocery bags) Chewy or crunchy foods. Draw shapes on child’s back Hyper (over responsive) Does fine motor activities and not gross motor. Participate in household chores (e.g. vacuum, dust, carry laundry basket)
