21．Ann Grand：a visual thinker
Ann Grand is a visual thinker.When somebody speaks to her，the words are instantly
translated into pictures，like a video in her head.Unlike most people，her thoughts move from
video﹣like images to generalizations and concepts.Furthermore，her memories usually appear in
her imagination in order of time，and the image visualized are always specific.For example，if she
thinks about a chimney，she sees detailed pictures，like the one in her old house，and then those in
her hometown.That one word can turn into a full﹣length video in her head.Grand's mind works
like the Internet search engine which produces dozens of images of an object a user is searching
for.
Visual thinking has enabled Grand to build entire systems in her imagination，which works
similarly to a computer program because it can produce three﹣dimensional design
simulations.This was important to her as an equipment designer for the livestock industry.Before
she started construction on her designs，she would test﹣run the equipment in her
mind.She formed mental pictures of her designs in every possible situation，with different sizes
and breeds of cattle and in different weather conditions.This process made it possible for her to
correct mistakes before construction started.
Grand's mind is also sensitive to details，which was important in her work with cattle.Her
sharp awareness of the visual world led to noteworthy observations about animals.She noticed
many little things that most people would not consider that scared the cattle.For example，a coat
on a fence or a pipe on the floor would frighten them away.Grand's visualization abilities have
also helped her understand the animals she has worked with.This led her to create designs ranging
from sweeping，curved fences intended to reduce the stress experienced by animals that were
going to be killed to systems for handling sick cattle and pigs.
