Stereotyped behavior
Say fixed words and do fixed actions to relatives or strangers, not knowing that it should change from person to person, from time to time and from place to place; Treat toys or certain items in a fixed way; Be dependent on certain items. It is often manifested in saying fixed words and doing fixed actions before and after eating, before and after sleeping, before and after going to the toilet, before going out and just returning home. These are called ritual behaviors. Many autistic children have fixed ways of using their bodies, such as squinting at people, walking on tiptoe, playing with their own voices (barking, laughing, talking to themselves), touching their lips and ears with their hands, clapping their hands, stamping their feet, shaking their bodies back and forth, and turning in circles.
Abnormal reaction to the outside world
Many parents with autism describe their children as "deaf" and "blind", so they have had the experience of taking their children to otolaryngology. They often behave as if nothing had happened, as if they were living in their own world forever, and what happened outside could not pollute them. There are also many autistic children who react strongly to some small changes in daily life and small stimuli that ordinary people don't agree with, such as covering their ears with their hands, as if they can hear sound stimuli that others can't feel, and some people are too excited or afraid of certain smells, colors, shapes and textures.
Interpersonal relationship disorder
Ignore people and play with yourself; No, (I don't stick to adults like ordinary children, I like adults to hug him and Doby to play with him). Some people describe that they regard their parents as "tools of life", and only hold their mother's hand when they want to eat (rather than "objects of affection"), and ignore their mother when they have nothing to do. Seeing mom coming and dad getting off work, he is not particularly happy and often doesn't respond; I'm not afraid to meet strangers and I don't know strangers. They are not interested in group games, rarely take the initiative to find someone to play, and rarely take the initiative to participate in the dialogue of a group of people. With the growth of age, some people will make progress in interpersonal relationships, but they still show the characteristics of not being interested in "people"
Communication disorder
