Almost half of all very young children with autism respond well to gently intrusive programs in which they are constantly encouraged to look at the teacher and interact. Brightly colored wall decorations made learning fun for me, but they may be too distracting for a child with sensory jumbling. The popular Lovaas program, developed at UCLA, is being used successfully there to mainstream nearly half of young autistic children into a normal kindergarten or first grade. The Lovaas method pairs words with objects, and the children are rewarded with praise and food when they correctly match a word with an object. While this program is wonderful for some kids, it is certain to be confusing and possibly painful for children with severe sensory jumbling and mixing problems.
These children require a different approach. Touch is often their most reliable sense, and they learn best if teachers use a tactile system. One mother taught her nonverbal daughter to draw a circle by holding her hand and guiding it to make a circle. Plastic letters that can be felt are often useful for teaching words. The more protected these children are from distracting sights and sounds, the more likely it is that their dysfunctional nervous system will be able to perceive speech accurately To help them hear better, teachers must protect them from visual stimuli that will cause sensory overload. They may hear best in a quiet, dimly illuminated room that is free of fluorescent lights and bright wall decorations. Sometimes hearing is enhanced if the teacher whispers or sings softly. Teachers need to speak slowly to accommodate a nervous system that processes information slowly. And sudden movements that will cause sensory confusion should also be avoided.
Children who are echolalic — who repeat what they hear— may be at a midpoint on the sensory processing continuum. Enough recognizable speech gets through for them to be able to repeat the words. Dr. Doris Allen, at the Albert Einstein Hospital in New York, emphasizes that echolalia should not be discouraged, so as not to inhibit speech. The child repeats what has been said to verify that he heard it correctly. Research by Laura Berk, at Illinois State University, has shown that normal children talk to themselves to help them control their behavior and learn new skills. Since autism is caused by immature brain development, it is likely that echolalia and self-talking, which occur in older autistic children, are the result of immature speech patterns.
Unlike normal children, who naturally connect language to the things in their lives at a remarkable rate, autistic children have to learn that objects have names. They have to learn that words communicate. All autistic children have problems with long strings of verbal information. Even very high-functioning people have difficulty following verbal instructions and find it easier to follow written instructions, since they are unable to remember the sequence of the information. My college math teacher once commented that I took excessive notes. He told me that I should pay attention and understand the concept. The problem was that it was impossible for me to remember the sequence of the problems without the notes. I learned to read with phonics and sounding out words, because I was able to understand speech by age three. Children with more severe auditory processing problems often learn to read before they can speak. They learn best if a written word is paired with an object, because many of them have very poor comprehension of spoken words.
As an adult my method for learning a foreign language may be similar to how a more severely impaired autistic child learns to understand language. I cannot pick words out of a conversation in a foreign language until I have seen them written first.
Two basic patterns of autistic symptoms can help identify which children will respond well to intensive, gently intrusive teaching methods, and which will not. The first kind of child may appear deaf at age two, but by age three he or she can understand speech. I was this kind. When adults spoke directly to me, I could understand them, but when they talked among themselves, it sounded like gibberish. The second kind of child appears to develop normally until one and a half or two and then loses speech. As the syndrome progresses, the ability to understand speech deteriorates and autistic symptoms worsen. A child that has been affectionate withdraws into autism as his sensory system becomes more and more scrambled. Eventually he may lose awareness of his surroundings, because his brain is not able to process and understand sights and sounds around him. There are also children who are mixtures of the two kinds of autism.
Children of the first kind will respond well to intensive, structured educational programs that pull them out of the autistic world, because their sensory systems provide a more or less accurate representation of things around them. There may be problems with sound or touch sensitivity, but they still have some realistic awareness of their surroundings. The second kind of child may not respond, because sensory jumbling makes the world incomprehensible. Gently intrusive teaching methods will work on some children who lose their speech before age two if teaching is started before their senses become totally scrambled. Catherine Maurice describes her successful use of the Lovaas program with her two children, who lost speech at fifteen and eighteen months of age, in her book, Let Me Hear Your Voice. Teaching was started within six months of the onset of symptoms. The regression into autism was not complete, and her children still had some awareness. If she had waited until they were four or five, it is very likely that the Lovaas method would have caused confusion and sensory overload.
My experience and that of others has shown that an effective teaching method coupled with reasonable amounts of effort should work. Desperate parents often get hooked into looking for magic cures that require ten hours a day of intensive treatment. To be effective, educational programs do have to be done every day, but they usually do not require heroic amounts of effort. My mother spent thirty minutes five days a week for several months teaching me to read. Mrs. Maurice had a teacher spend twenty hours a week on the Lovaas method with her children. In addition to participating in formal educational programs, young autistic children need a structured day, both in the school and at home. Several studies have shown that twenty to twenty-five hours a week of intensive treatment which required the child to constantly interact with his teacher was most effective. A neurologist gave my mother some very good advice: to follow her own instincts. If a child is improving in an educational program, then it should be continued, but if there is no progress, something else should be tried. Mother had a knack for recognizing which people could help me and which ones could not. She sought out the best teachers and schools for me, in an era when most autistic children were placed in institutions. She was determined to keep me out of an institution.
A controversial technique called facilitated communication is now being used with nonverbal people with autism. Using the technique, the teacher supports the person's hand while he or she taps out messages on a typewriter keyboard. Some severely handicapped people have problems with stopping and starting hand movements, and they also have involuntary movements that make typing difficult. Supporting the person's wrist helps to initiate motion of the hand toward the keyboard and pulls his fingers off the keyboard after he pushes a key to prevent perseveration and multiple pushing of a single key. Merely touching the person's shoulder can help him initiate hand movements.
