  28. We live surrounded by a world that transmits hundreds of information inputs per minute that our brain must decode. And for this, our body not only uses the five known senses (sight, smell, hearing, touch and taste). Sensory senses are also involved, which are part of sensory integration. Essay Writers Online

    Today we explain what sensory integration is, its implication in the education of the children and the ways of facing the problems derived from this capacity. Let’s see what it is.

    What is sensory integration?
    The Sensory integration is the ability that allows us to interpret the information they give us our sense organs and our external environment. It is also the ability to generate timely responses to each situation. For example: the chill because of a scratch on the blackboard, the pain of a sting or the sensation of cold / heat.

    Developed by Dr. Jean Ayres, the general theory of sensory integration understands that the neurological functioning of children is related to their sensorimotor behavior and their academic learning .

    Learning and sensory integration: dysfunctions
    On many occasions, learning problems have little to do with the intelligence or intellectual capacity of the child. But they come because of problems in sensory integration. That is, the brain does not have the capacity to adequately process information and some type of sensory integrative dysfunction occurs.

    Sensory integration is based on three basic senses: the tactile, the vestibular and the proprioceptive. Systems that begin to develop at birth and that make us experiment, interpret and respond to different stimuli.

    Everyone knows what the tactile consists of. But the vestibular and proprioceptive are concepts that can be new. The vestibular system is responsible for the sense of movement of our own body in space. It gives orientation, security, balance and posture to the body. The proprioception system is what gives us the ability to feel the relative position of each part of the body.

    When some connection fails, external or internal stimuli are misinterpreted and responded with excessive or inadequate reactions. It is when the Sensorial Integration Dysfunction (DIS) or the Disorder in the Sensorial Processing (DPS) appear.

    These dysfunctions can directly affect the level of activity, motor coordination and even speech or school performance . They also affect behavior, appearing problems of distraction, impulsivity and even frustration and aggression. Repercussions that directly interfere in the child’s cognitive development and learning.

    Coping with dysfunctions: therapy
    To treat these dysfunctions related to sensory integration, there is sensory integration therapy . It was designed to improve the sensory processing of children through repetitive and structured stimulation. Known in English as SI Therapy, it is applied by an occupational therapist or an educator with specific training.

    The therapy consists of providing the necessary tools to improve the organization of the central nervous system, modulate the information and find the most appropriate response in each situation. This ‘treatment’ is especially recommended for DIS or DPS, because the child is able to learn by himself when and how to use them. A characteristic that will effectively affect your personal growth.
