Generally speaking, people's sense of concept refers to sight, hearing, taste and smell, but in fact, the most basic and important senses needed by human survival are touch, vestibular sense and motor sense. Touch refers to the feeling that nerve cells distributed throughout the skin receive external temperature, humidity, pain, pressure and vibration. The sense of vestibular balance is to use three pairs of semicircular canals and otoliths (calcium carbonate crystals) in the inner ear to detect gravity, control the position of the head in activities and maintain the balance of the body. The sense of movement (also known as the sense of depth) comes from the muscles and joints inside our bodies. Is the feeling of knowing the position and movement of limbs. The study of human senses runs through one's life. Simply put, it is a learning process in which the brain and the body coordinate with each other. Without sensory integration, neither the brain nor the body can develop. The most critical period of sensory integration learning is before the age of 7, because during this period, people's brains develop very fast.
The learning of the brain depends on the input of the body senses, and the brain after learning exerts the ability to command the body and senses. Because the nervous system of brain, body and sensory organs is very complex and needs to be integrated. If this ability is insufficient, it will lead to learning confusion in the brain, body and sensory organs, resulting in sensory integration disorder. This kind of learning has laid almost 80% of the foundation in infancy.
At present, due to various reasons (urbanized life reduces the activity space, outdoor activities, and the lack of life of the only child group, etc. ), the sensory learning in infancy is obviously insufficient, especially the learning of touch, vestibular balance and motor sense. Therefore, there are more and more children with sensory integration disorder. Domestic research shows that 10-30% of children have sensory integration disorder in different degrees. The chief culprit of the failure of sensory integration is urbanized life and small family system. Behavioral disorders caused by sensory integration disorder: fidgeting, inattention, clumsiness and serious shyness. , has been bothering teachers and parents. Sensory integration therapy proposed by Ayers provides these children with opportunities for correction, and also solves the problems of parents and teachers for children with high IQ and low grades.
