Guide to Sensory Processing.Pdf Guide to Sensory Processing Prepared by Allison Travnik, MSOTS Level II Fieldwork Student Project Kavitha N Krishnan MS OTR/L Fieldwork Instructor Sensory Processing In order to understand what is going on around us, we need to organize all of the incoming sensory information (Ayres, 2005). The sensory information involves what we see, smell, taste, hear, feel on our body, where our body is in relation to others, and how well we are balanced. This is a lot of information that our brains need to process in order to engage in productive behavior, learn, and form accurate perceptions.

Travis is constantly moving, pushing, or chewing on things. The collar of his shirt and coat are always wet from chewing. When talking to people, he tends to push up against you. Or do you know another child? Sierra does not like to be hugged or kissed by anyone. She gets upset with other children bump up against her. She doesn’t like socks with a heel or toe seam or any tags on clothes. Why is Travis always chewing? Why doesn’t Sierra liked to be touched? Why do children react differently to things around them? These children have different ways of reacting to the things around them, to sensations. Over the years, different terms (such as sensory integration) have been used to describe how children deal with the information they receive through their senses. Currently, the term being used to describe children who have difficulty dealing with input from their senses is sensory processing disorder. _____________________________________________________________________ Sensory Processing Disorder

  • What Is Sensory Defensiveness? by Ann Stensaas, M.S., OTR/L
    Super Duper® Handy Handouts!® Number 174 What Is Sensory Defensiveness? by Ann Stensaas, M.S., OTR/L Does your child get upset by tags in clothing, the sound of the vacuum cleaner, or certain smells in the environment? If so, your child may be showing signs of sensory defensiveness. Sensory defensiveness is a negative reaction to one or more types of sensations (such as touch, movement, sound, taste/texture, or smell), often requiring you to control his/her daily routine to avoid such things. Types of Sensory Defensiveness There are different types of sensory defensiveness including tactile (touch), gravitational (movement and balance), auditory (hearing), and oral defensiveness (taste, smell, texture). Tactile Defensiveness (Touch) The tactile system is our sense of touch. It protects us from danger and helps us identify different objects in the environment. A child showing signs of tactile defensiveness may: Overreact to ordinary touch experiences (e.g., touching play dough or being touched by someone). Avoid daily activities (e.g., washing face/hands or brushing hair). Avoid light touch (e.g., a kiss) but seek out deep touch (e.g., a bear hug). Vestibular Insecurity (Balance/Movement) The vestibular system is our sense of movement and balance. It tells us where our head and body are in relation to gravity and other objects and supports our vision, posture, emotions, and coordination skills. A child showing signs of gravitational insecurity may: Have an excessive fear of falling during ordinary movement activities (e.g., swinging, riding a bicycle, or climbing). Become overwhelmed by changes in head position (e.g., being upside down).

  • Sensory Integration: Understanding and Meeting Your Child’S Needs
    Sensory Integration: Understanding and Meeting Your Child’s Needs Sandra Falk,OTR Carrie D. Gross, PTA Le Bonheur Early Intervention and Development (LEAD) What are the Senses? The common senses are: Taste Smell Vision Hearing Touch Two hidden senses are: Vestibular (sense of movement) Proprioception (sensations from muscles and joints). What is Sensory Integration? It is our ability to take in information from the world around us through our senses, sort it out in the brain, and respond to it successfully. It takes place automatically, without us having to “think” about it. How Does Sensory Integration Develop? Sensory integration is pre-programmed to develop from conception However, it takes sensory experiences to activate and/or enhance this process We are designed to enjoy things that promote the development of our brain, and therefore seek out sensations that help organize our brain All of us have sensory preferences and “issues” that we accommodate for on a daily basis. It is when sensory difficulties interfere with everyday life that it becomes a problem. When there is a problem: If the brain is unable to understand and process sensory information efficiently, then that child may have a difficult time functioning in every day life. The child may be awkward and clumsy, fearful and withdrawn, or hostile and aggressive. It can affect how a child moves and learns, how he behaves, how he plays and makes friends, and how he feels about himself. A lot children have some sensory issues, and would benefit from their caregivers understanding their sensory needs. If the problems are severe and interfere with everyday life, a therapist can evaluate and help establish a plan of care.

  • Sensory Perception in Autism
    REVIEWS Sensory perception in autism Caroline E. Robertson1,2,3* and Simon Baron-Cohen4 Abstract | Autism is a complex neurodevelopmental condition, and little is known about its neurobiology. Much of autism research has focused on the social, communication and cognitive difficulties associated with the condition. However, the recent revision of the diagnostic criteria for autism has brought another key domain of autistic experience into focus: sensory processing. Here, we review the properties of sensory processing in autism and discuss recent computational and neurobiological insights arising from attention to these behaviours. We argue that sensory traits have important implications for the development of animal and computational models of the condition. Finally, we consider how difficulties in sensory processing may relate to the other domains of behaviour that characterize autism.

  • Sensory Processing Disorder
    Sensory Integration Sensory processing (sometimes called "sensory integration" or SI) is a term that refers to the way the nervous system receives messages from the senses and turns them into appropriate motor and behavioral responses. Whether you are biting into a hamburger, riding a bicycle, or reading a book, your successful completion of the activity requires processing sensation or "sensory integration." Sensory Processing Disorder (SPD, formerly known as "sensory integration dysfunction") is a condition that exists when sensory signals don't get organized into appropriate responses. Pioneering occupational therapist and neuroscientist A. Jean Ayres, PhD, likened SPD to a neurological "traffic jam" that prevents certain parts of the brain from receiving the information needed to interpret sensory information correctly. A person with SPD finds it difficult to process and act upon information received through the senses, which creates challenges in performing countless everyday tasks. Motor clumsiness, behavioral problems, anxiety, depression, school failure, and other impacts may result if the disorder is not treated effectively. One study (Ahn, Miller, Milberger, McIntosh, 2004) shows that at least 1 in 20 children’s daily lives is affected by SPD. Another research study by the Sensory Processing Disorder Scientific Work Group (Ben-Sasson, Carter, Briggs-Gowen, 2009) suggests that 1 in every 6 children experiences sensory symptoms that may be significant enough to affect aspects of everyday life functions. Symptoms of Sensory Processing Disorder, like those of most disorders, occur within a broad spectrum of severity. While most of us have occasional difficulties processing sensory information, for children and adults with SPD, these difficulties are chronic, and they disrupt everyday life.

  • Auditory Nerve.Pdf
    1 Sound waves from the auditory environment all combine in the ear canal to form a complex waveform. This waveform is deconstructed by the cochlea with respect to time, loudness, and frequency and neural signals representing these features are carried into the brain by the auditory nerve. It is thought that features of the sounds are processed centrally along parallel and hierarchical pathways where eventually percepts of the sounds are organized. 2 In mammals, the neural representation of acoustic information enters the brain by way of the auditory nerve. The auditory nerve terminates in the cochlear nucleus, and the cochlear nucleus in turn gives rise to multiple output projections that form separate but parallel limbs of the ascending auditory pathways. How the brain normally processes acoustic information will be heavily dependent upon the organization of auditory nerve input to the cochlear nucleus and on the nature of the different neural circuits that are established at this early stage. 3 This histology slide of a cat cochlea (right) illustrates the sensory receptors, the auditory nerve, and its target the cochlear nucleus. The orientation of the cut is illustrated by the pink line in the drawing of the cat head (left). We learned about the relationship between these structures by inserting a dye-filled micropipette into the auditory nerve and making small injections of the dye. After histological processing, stained single fibers were reconstruct back to their origin, and traced centrally to determine how they terminated in the brain. We will review the components of the nerve with respect to composition, innervation of the receptors, cell body morphology, myelination, and central terminations.

  • What Is Sensory Integration?
    WHAT IS SENSORY INTEGRATION? Sensory integration is the brain's innate ability to take in (register and perceive) information from the environment through the various senses, process and organize the information and then use it effectively. WHAT IS SENSORY INTEGRATION DYSFUNCTION? Sensory integration dysfunction is when the brain is unable to process the information received from the senses. When this occurs, the brain cannot analyze, organize or integrate this information to produce a functional outcome. POSSIBLE SYMPTOMS OF SENSORY INTEGRATION DYSFUNCTION Hyper or hypo sensitive to touch, movement, sight, sounds or smells. Activity level which is too high or too low. Coordination problems. Delays in speech, language, motor skills and academic achievement. Poor organization of behavior Poor self-concept (body awareness) THE VESTIBULAR SYSTEM Vestibular processing refers to the information that is provided by the receptors within the inner ear. These receptors are stimulated by movement of the head and input from other senses. This input tells where we are in relation to gravity, whether we are still or moving, how fast we are going, and in which direction. It also influences the development of balance, equilibrium, postural control and muscle tone. Vestibular input also plays an important role in helping to maintain a calm, alert state and keeping the level of arousal in the central nervous system balanced. An under-reactive vestibular system can contribute to distractibility and hyperactivity due to the lack of its modulating influence. Depending upon the situation, vestibular stimulation can either calm or stimulate and facilitate a more organized activity level. Children can be hyper and/or hypo-responsive to this type of input.

(credit: modification of work by Hermanus Backpackers Hostel, South Africa) Chapter Outline 36.1: Sensory Processes 36.2: Somatosensation 36.3: Taste and Smell 36.4: Hearing and Vestibular Sensation 36.5: Vision Introduction In more advanced animals, the senses are constantly at work, making the animal aware of stimuli—such as light, or sound, or the presence of a chemical substance in the external environment—and monitoring information about the organism’s internal environment. All bilaterally symmetric animals have a sensory system, and the development of any species’ sensory system has been driven by natural selection; thus, sensory systems differ among species according to the demands of their environments. The shark, unlike most fish predators, is electrosensitive—that is, sensitive to electrical fields produced by other animals in its environment. While it is helpful to this underwater predator, electrosensitivity is a sense not found in most land animals. 36.1 | Sensory Processes By the end of this section, you will be able to do the following: • Identify the general and special senses in humans • Describe three important steps in sensory perception • Explain the concept of just-noticeable difference in sensory perception Senses provide information about the body and its environment. Humans have five special senses: olfaction (smell), gustation (taste), equilibrium (balance and body position), vision, and hearing.

  • Sensory Processing Disorder Facts
    Sensory Processing Disorder Facts: Sensory processing disorder is a condition in which the brain has trouble receiving and responding to information that comes in through the senses. The condition used to be called sensory integration dysfunction. Sensory Processing involves the brains ability to organize and understand an array of incoming sensory information entering the brain at the same time. Sensory processing is fundamental to the development of all motor and social skills. This is a filtering system to determine pathways for incoming sensory information. There are the familiar senses of sight, taste, smell, and hearing, but sensory processing involves 3 additional specialized sensory systems, which are very influential with regard to how effectively we recognize and organize incoming sensory information. These are: •Tactile System: how our body perceives touch •Proprioceptive System: how are body perceives where we are in space •Vestibular System: how are body perceives directionality and sense of movement. Some people with sensory processing disorder are oversensitive to things in their environment. Common sounds may be painful or overwhelming. The light touch of a shirt may chafe the skin. This could manifest in: • Being uncoordinated • Bumping into things • Being unable to tell where their limbs are in space • Being hard to engage in conversation or play Sensory processing problems are usually identified in children. But they can also affect adults. Sensory processing problems are commonly seen in developmental disorders like autism. Sensory processing disorder is not recognized as a stand- alone disorder. But many experts think that should change. Sensory processing disorder may affect one sense, like hearing, touch, or taste.
