Children’s health is the most important concern for many parents. However, from the psychological behavior department of Kaifeng Children’s Hospital, many parents often complain: usually children always eat well and use well, and there is no disease, why is the energy in class is not concentrated, encounter interested in the focus of attention, not interested in the attention will be scattered, the teacher also said my child often deserted, this is why? 1, sensory dysfunction: when the child’s vestibular balance is poor, it will cause poor control of body movements. This is not a problem of education methods, but the child’s brain sensory function development is not coordinated caused. 2, physiological reasons: caesarean section, lack of crawling exercise when young, lead overload, children’s brain development is not perfect, the development of the nervous system excitation and inhibition process is not balanced, etc. may lead to children’s inattentiveness, and therefore poor self-control. 3, poor comprehension: the class may be distracted because the child can not understand the teacher’s lecture content, the teacher’s knowledge failed to enter the child’s existing knowledge structure. At this time, the child’s comprehension should be improved to fill the knowledge gap, the child’s attention will be focused on the class work for a long time. 4.Sensory ability lags behind: Some children are already in elementary school, but still can’t roll, can’t catch or throw a ball, don’t dare to walk the balance beam, moreover can’t jump rope, can’t distinguish direction. The backwardness of these motor functions prevents them from extracting useful sensory information from the external world, and many sensory information fails to reach the brain, resulting in the phenomenon of seeing but not seeing, hearing but not hearing. 5, psychological reasons: in order to attract the attention of others, to get attention, or to escape from the excessive burden given by parents, they subconsciously pass some behaviors to achieve the purpose. Psychological, excessive learning pressure, bad emotions, mental illness, etc. can affect the concentration of children’s attention. 6, listening to the breadth of inadequate: auditory memory breadth is the range of sentences or bytes that a person can receive when instantly remembering in the case of concentration. Auditory memory breadth and human attention span are more closely related. Children with a serious lack of auditory breadth often have to repeat what adults say, he can only repeat half or even less, and school assignments can not remember all the cases. 7, weak anti-disturbance ability: Some children have good self-control, but as long as someone is moving and talking next to him, he will not be able to focus, but school is a large group, children must have good anti-disturbance ability, learning efficiency, etc. will be higher. 8, the disadvantages of intergenerational education: due to the concept, quality, emotional and other factors, the older generation is often overindulged children, and even arranged to replace, so that children develop a serious dependence, lack of autonomy and self-care ability, so that independent learning, can not focus on things. 9.Children’s hyperactivity disorder: hyperactivity disorder is a common child psychological disorders, these children are generally normal intelligence, but there are not in line with the actual age of inattention, too much activity, impulsive capricious, poor self-control characteristics, which affect learning. 10.Lead poisoning: Lead can make the figurative intelligence, visual-motor function, memory, impaired reaction time, language and spatial abstraction, sensory and behavioral functions change, and symptoms such as fatigue, insomnia, irritability, headache, and hyperactivity appear. It can be seen: the reasons for children’s inattentiveness in class are many, so parents in the discovery of children’s inattentiveness, do not just blame the child, which is not only ineffective, but also seriously affect the child’s interest in learning and enthusiasm to take the child to a professional hospital in time to carry out relevant checks, with targeted treatment programs.
