Children with autism appear to be distanced from our existing world. When people observe a child with autism they often feel that children with autism are in a world of their own. Viewing from the aspect of an autistic child he/she enters a world of their own imagination. They may imagine a funny image or a funny act and they tend to laugh by themselves. When we see them, we can observe that the child is not paying attention to us and laughing for nothing. The key is to bring their attention by diverting them into any activity of their interest involving greater attention span and appreciating the child when he completes the activity.
