For example, many people see a generalized generic church rather than specific churches and steeples when they read or hear the word steeple. Their thought patterns move from a general concept to specific examples. I used to become very frustrated when a verbal thinker could not understand something I was trying to express because he or she couldn't see the picture that was crystal clear to me. Further, my mind constantly revises general concepts as I add new information to my memory library. It's like getting a new version of software for the computer. My mind readily accepts the new «software,» though I have observed that some people often do not readily accept new information.
Unlike those of most people, my thoughts move from videolike, specific images to generalization and concepts. For example, my concept of dogs is inextricably linked to every dog I've ever known. It's as if I have a card catalogue of dogs I have seen, complete with pictures, which continually grows as I add more examples to my video library. If I think about Great Danes, the first memory that pops into my head is Dansk, the Great Dane owned by the headmaster at my high school. The next Great Dane I visualize is Helga, who was Dansk's replacement. The next is my aunt's dog in Arizona, and my final image comes from an advertisement for Fitwell seat covers that featured that kind of dog. My memories usually appear in my imagination in strict chronological order, and the images I visualize are always specific. There is no generic, generalized Great Dane.
However, not all people with autism are highly visual thinkers, nor do they all process information this way. People throughout the world are on a continuum of visualization skills ranging from next to none, to seeing vague generalized pictures, to seeing semi-specific pictures, to seeing, as in my case, in very specific pictures.
I'm always forming new visual images when I invent new equipment or think of something novel and amusing. I can take images that I have seen, rearrange them, and create new pictures. For example, I can imagine what a dip vat would look like modeled on computer graphics by placing it on my memory of a friend's computer screen. Since his computer is not programmed to do the fancy 3-D rotary graphics, I take computer graphics I have seen on TV or in the movies and superimpose them in my memory. In my visual imagination the dip vat will appear in the kind of high-quality computer graphics shown on Star Trek. I can then take a specific dip vat, such as the one at Red River, and redraw it on the computer screen in my mind. I can even duplicate the cartoonlike, three-dimensional skeletal image on the computer screen or imagine the dip vat as a videotape of the real thing.
Similarly, I learned how to draw engineering designs by closely observing a very talented draftsman when we worked together at the same feed yard construction company David was able to render the most fabulous drawings effortlessly After I left the company I was forced to do all my own drafting. By studying David's drawings for many hours and photographing them in my memory I was actually able to emulate David's drawing style. I laid some of his drawings out so I could look at them while I drew my first design. Then I drew my new plan and copied his style. After making three or four drawings, I no longer had to have his drawings out on the table. My video memory was now fully programmed. Copying designs is one thing, but after I drew the Red River drawings, I could not believe I had done them. At the time, I thought they were a gift from God. Another factor that helped me to learn to draw well was something as simple as using the same tools that David used. I used the same brand of pencil, and the ruler and straight edge forced me to slow down and trace the visual images in my imagination.
My artistic abilities became evident when I was in first and second grade. I had a good eye for color and painted watercolors of the beach. One time in fourth grade I modeled a lovely horse from clay. I just did it spontaneously, though I was not able to duplicate it. In high school and college I never attempted engineering drawing, but I learned the value of slowing down while drawing during a college art class. Our assignment had been to spend two hours drawing a picture of one of our shoes. The teacher insisted that the entire two hours be spent drawing that one shoe. I was amazed at how well my drawing came out. While my initial attempts at drafting were terrible, when I visualized myself as David, the draftsman, I'd automatically slow down.
Processing Nonvisual Information
Autistics have problems learning things that cannot be thought about in pictures. The easiest words for an autistic child to learn are nouns, because they directly relate to pictures. Highly verbal autistic children like I was can sometimes learn how to read with phonics. Written words were too abstract for me to remember, but I could laboriously remember the approximately fifty phonetic sounds and a few rules. Lower-functioning children often learn better by association, with the aid of word labels attached to objects in their environment. Some very impaired autistic children learn more easily if words are spelled out with plastic letters they can feel.
Spatial words such as «over» and «under» had no meaning for me until I had a visual image to fix them in my memory. Even now, when I hear the word «under» by itself, I automatically picture myself getting under the cafeteria tables at school during an air-raid drill, a common occurrence on the East Coast during the early fifties. The first memory that any single word triggers is almost always a childhood memory. I can remember the teacher telling us to be quiet and walking single-file into the cafeteria, where six or eight children huddled under each table. If I continue on the same train of thought, more and more associative memories of elementary school emerge. I can remember the teacher scolding me after I hit Alfred for putting dirt on my shoe. All of these memories play like videotapes in the VCR in my imagination. If I allow my mind to keep associating, it will wander a million miles away from the word «under,» to submarines under the Antarctic and the Beatles song «Yellow Submarine.» If I let my mind pause on the picture of the yellow submarine, I then hear the song. As I start humming the song and get to the part about people coming on board, my association switches to the gangway of a ship I saw in Australia.
I also visualize verbs. The word jumping triggers a memory of jumping hurdles at the mock Olympics held at my elementary school. Adverbs often trigger inappropriate images—«quickly» reminds me of Nestle's Quik — unless they are paired with a verb, which modifies my visual image. For example, «he ran quickly» triggers an animated image of Dick from the first-grade reading book running fast, and «he walked slowly» slows the image down. As a child, I left out words such as «is,» «the,» and «it,» because they had no meaning by themselves. Similarly, words like «of» and «an» made no sense. Eventually I learned how to use them properly, because my parents always spoke correct English and I mimicked their speech patterns. To this day certain verb conjugations, such as «to be,» are absolutely meaningless to me.
When I read, I translate written words into color movies or I simply store a photo of the written page to be read later. When I retrieve the material, I see a photocopy of the page in my imagination. I can then read it like a TelePrompTer. It is likely that Raymond, the autistic savant depicted in the movie Rain Man, used a similar strategy to memorize telephone books, maps, and other information. He simply photocopied each page of the phone book into his memory. When he wanted to find a certain number, he just scanned pages of the phone book that were in his mind. To pull information out of my memory, I have to replay the video. Pulling facts up quickly is sometimes difficult, because I have to play bits of different videos until I find the right tape. This takes time.
