Children with autism have difficulty being amused because the main symptoms of autistic children are a narrow range of interests, poor emotional communication, and withdrawn behavior, as well as poor intellectual development such as speech and language skills. There are two main reasons for this: 1) poor intellectual development or poor verbal development, so it is difficult to be amused by verbal or even non-verbal signals from adults, such as gestures, smiley faces, and strange faces, because it is difficult to recognize these things. 2) Poor emotional communication in autistic children, such as fear, fear, and crying in other children, but it is difficult for this child to respond accordingly. The child also cannot communicate with other children emotionally or emotionally, and cannot have a lot of advanced emotional communication with adults, such as feelings of dependence, affection and mutual intimacy, so it is difficult to be amused.
