I believe that it is not easy for every parent to accept that their child has autism. Not only is there no known cause of autism, but there is no known outcome of treatment. Each child with autism is different and develops differently, and their behavior is often overwhelming to parents. This article provides an overview of the main characteristics of autism, particularly language and social difficulties, in the hope that it will help parents understand more about the difficulties their children face and help them develop their potential. The diagnosis of autism is broadly based on three areas in which the child must demonstrate: 1) difficulty interacting socially; 2) deficits in verbal communication; and 3) stubborn patterns of behavior. An analogy from a clinical psychologist, Sue Hankey, might give parents a better idea of their thought and behavior patterns. They are like a tourist who is not fluent in Japanese and is traveling to Japan for the first time. After dropping off their luggage at the hotel, they realize they don’t have a camera with them. In order not to miss the opportunity to take pictures of the sightseeing, the only way to get to the nearest store is to ask the guide. Although the guide explained patiently, his instructions were too complicated, not only did he have to turn left and right, but he also had to remember the characteristics of each street. After listening to the instructions, the tourist had to go on his way with fear and trepidation. He was apprehensive all the way, afraid that once lost, there is no way to seek help. Fortunately, the tourist arrived at the store without any problems. After buying a camera, he returned the way he came. For the next few nights, the tourist only dared to follow this route to go out shopping. As they were familiar with it, the tourists were no longer in fear. Later, the tourist found out that the store was not far away and there was no need to take this winding road and cursed himself for being so stupid. This example illustrates the behavioral manifestations of autistic children. The main symptoms they exhibit are: communication difficulties, social interaction difficulties, and repetitive paranoid behaviors or interests. However, the severity and stage of development of each symptom may vary among children. (i) Communication Disorders Many children with autism have slower language development than the average child, and their ability to use vocabulary is quite limited. Even those with more normal language skills may show significant difficulties in using language. They often have difficulty initiating or appropriately broaching appropriate topics and conversing on a single topic; or they may only be able to speak to others about topics that interest them. These situations are similar to those in which a person who does not know Japanese travels to Japan and cannot speak, understand, or read. Even children who are able to develop speaking skills may not be able to communicate effectively with others because of poor diction or other language problems. （For children with autism, things that children generally enjoy, such as being hugged by adults and playing games with others, are not necessarily fun. As a result, many parents will report that their child was very well behaved as an infant and rarely cries for adult attention or for someone to hold him. They do not respond pleasantly to adult voices, expressions, or physical contact. Some children even have a strong aversion to physical contact with people. Many articles state that children with autism are unable to communicate emotionally or respond appropriately to the actions of others. They have great difficulty understanding the thoughts of others or experiencing their emotions. Their difficulty lies in not mastering nonverbal communication skills such as eye contact, facial expressions, gestures, and body language. Because of this, children with autism often choose to be isolated. Even when barely participating in group activities, they may appear anxious and uncomfortable. A small number of socially motivated children are motivated but do not interact with others in an appropriate manner. These behaviors are difficult to accept, such as talking to people face-to-face. (iii) Repetitive Paranoid Behaviors Nothing bothers parents more than the stubborn behavior patterns of young children with autism. Once a habit is established or a certain pleasure is obtained, it is not easy to change. While children with autism often feel anxious about not being able to cope with the challenges of daily life, repetitive behavioral patterns can enhance their sense of control over their surroundings, thereby reducing anxiety. Parents don’t understand why they get so angry when their habits are violated. Just consider the example of a tourist to understand the difficulties faced by children with autism.
