Thinking in Pictures: My Life with Autism by Temple Grandin Read Free Book Online Page B

in the lower primary visual and auditory cortex and more conceptual thinking is in association areas where inputs from different parts of the brain are merged.
    Categories are the beginning of concept formation. Nancy Minshew found that people with autism can easily sort objects into categories such as red or blue, but they have difficulty thinking up new categories for groups of common objects. If I put a variety of common things on a table such as staplers, pencils, books, an envelope, a clock, hats, golf balls, and a tennis racquet, and asked an individual with autism to pick out objects containing paper, they could do it. However, they often have difficulty when asked to make up new categories. Teachers should work on teaching flexibility of thinking by playing a game where the autistic individual is asked to make up new categories for the objects like objects containing metal, or objects used in sports. Then the teacher should get the person to explain the reason for putting an object in a specific category.
    When I was a child I originally categorized dogs from cats by size. That no longer worked when our neighbors got a small dachshund. I had to learn to categorize small dogs from cats by finding a visual feature that all the dogs had and none of the cats had. All dogs, no matter how small, have the same nose. This is sensory-based thinking, not language-based. The animals could also be categorized by sound, barking versus meowing. A lower-functioning person may categorize them by smell or touch because those senses provide more accurate information. Dividing information into distinct categories is a fundamental property of the nervous system. Studies with bees, rats, and monkeys all indicate that information is placed into categories with sharp boundaries. French scientists recorded signals from the frontal cortex of a monkey's brain while it was looking at computer-generated images of dogs that gradually turned into cats. There was a distinct change in the brain signal when the category switched to cat. In the frontal cortex, the animal image was either a dog or a cat. When categorizing cats from dogs by size no longer worked for me, I had to form a new category of nose type. Research by Itzahak Fried at UCLA has shown that individual neurons learn to respond to specific categories. Recordings taken from patients undergoing brain surgery showed that one neuron may respond only to pictures of food and another neuron will respond only to pictures of animals. This neuron will not respond to pictures of people or objects. In another patient, a neuron in the hippocampus responded to pictures of a movie actress both in and out of costume but it did not respond to pictures of other women. The hippocampus is like the brain's file finder for locating information in stored memory.
    Becoming More Normal
    More knowledge makes me act more normal. Many people have commented to me that I act much less autistic now than I did ten years ago. A person who attended one of my talks in 2005 wrote on my evaluation, “I saw Temple in 1996, it was fun to see the poise and presentation manner she has gained over the years.” My mind works just like an Internet search engine that has been set to access only images. The more pictures I have stored in the Internet inside my brain the more templates I have of how to act in a new situation. More and more information can be placed in more and more categories. The categories can be placed in trees of master categories with many subcategories. For example, there are jokes that make people laugh and jokes that do not work.There is then a subcategory of jokes that can only be told to close friends. When I was a teenager I was called “tape recorder” because I used scripted lines. As I gained experience, my conversation became less scripted because I could combine new information in new ways. To help understand the autistic brain I recommend that teachers and parents should play with an Internet
