Sensory processing usually means sensory integration or SI. This term refers to the way in which our nervous system receives messages from our senses and the nervous system then turns them into appropriate responses. Whether you are biting into a cookie, or washing your hands, in order to complete the activity successfully requires you to process the sensation or in other words, undergo sensory integration. Sensory processing disorder or sensory integration dysfunction happens when sensory signals do not get organized in the appropriate responses. An Occupational therapist and neuroscientist A.Jean Ayres,PhD compares Sensory Processing Disorder (SPD) to a traffic jam. This traffic jam prevents certain areas of the brain to receive the information necessary to interpret the sensory information correctly. An individual with Sensory Processing Disorder finds it very hard to process and act upon sensory information, which can create challenges in everyday tasks. This SPD can lead to motor clumsiness, anxiety, behavioral problems, and also school failure. One study shows that 1 in every 6 children experience sensory symptoms that could be significant enough to affect aspects of their everyday lives. Symptoms of Sensory Processing Disorder occur on a broad spectrum. The average person will have the occasional difficulty processing sensory information however, for children and adults with SPD these difficulties are continuous and can disrupt their everyday life.
