ADHD children what are the main manifestations of perceived defects

Perception refers to human sensation and perception. Feeling is the starting point of the awareness of the reality, is through sight, sound, touch, taste, smell and other sensory organs to achieve. Vision and hearing are particularly important. On the basis of sense perception is that people in various, on objective things reflected in the human brain as a whole. Process of perception is: first of all is the feeling by sense organ on stimuli have accepted; receive the feeling through the nerves to the central information, and analysis of information; and then made when processing the analysis information of action reactions or to storage.
Perceived defects of ADHD children, mainly in: perception of speed slow, narrow the scope of perception, perception of ability to distinguish weak, perception process analysis process of a lack of initiative and enthusiasm.
(1) Visual vision is perceived outside one of the things most important feeling. Without vision is of course not accepted outside of colorful stimulus, depending on if you do not take the initiative to see things from the outside world, also have a blind eye. Students of the class need to be highly sensitive to accept the content of the class of Visual, often require that students sometimes see the books, sometimes looking at the Blackboard. Must to look from the more recent books, books to less far. ADHD children because of the perceived speed slow, prone to keep pace with the needs of the actual speed, often read books, forgot to Blackboard; or look at the Blackboard, and content of the book could not be found, often have too many things to take care of at the same time. And poor vision initiative and directed, often to look to other unrelated stimulus, cannot distinguish primary and secondary, looking around, did not seize the thing. Therefore, the information captured is very fuzzy, or no catch. Some may be due to physical defects in children, such as myopia, hyperopia, amblyopia, astigmatism, and color blindness, Visual acuity decrease, causing the object confusion, difficulties would also feel accepted.
(2) the hearing in General, ADHD children on hearing no unusual phenomenon, but on sound resolution and the ability to accept poor, audiovisual coordination enough, such as listening to the teacher\'s lectures, it is too late to see the Blackboard content, unclear or read the books you listen to the teacher carefully. Often have a \"deaf ear\" phenomenon. Especially for more complex, requires analysis of content, lack of ability to process analysis quickly, often could not understand the phenomenon. Unrelated things, such as trumpets sound, cars outside of the classroom or hawkers hawking sound, very easily lead to unconscious attention in children with hyperactivity. Hearing attracted by unrelated stimulus, distracting. The result, a class, do not know what the teacher is. Sometimes the teacher assigned homework and put forward the requirements are not heeded, returned to the House, naturally do not know what lessons the review.
(3) time perception from the beginning of school-age children, started strict with time, to go to school on time, on time, on time, on time job class in class, and so on. These all require students to have strict time concept. ADHD children often lack the strict concept of time, not master the time correctly, such as the East West school can be in the streets around, which was late for school; lesson unfinished, was impatient or to do small, some even rushed out of the classroom to play out; time is up, watching TV or playing games. Get up, eating, bathing, homework should parents supervise and help, the lack of active ability to master and manage your time. The completion of the required job or task, ADHD children to children spend more time than normal.
(4) space perception of each object in the space has a certain size, shape and location. Everything to correct perception, we must rely on space perception. School-age children\'s space perception than preschool has been developed, to size, shape, and position the object in General is well legible. ADHD children known sinking of space there is a defect, often seen when looking at a picture to the General, see the details; leak prone to error in reading or copying or copied. On the relativity of direction easy mistake, up and down, left and couldn\'t, such as easy as for 6 9, take b d and so on. We map from the match has been found in tests of similar phenomena. Matches have 10 different simple graphics, graphic into upper and lower column 10, 10 and 10 of the following graphs the order listed on different (random) for children to find two identical graphics to pair up and down. Error investigation found that ADHD children much more than normal children.
