  • >> The Aborigines of Australia have survived the trackless

  • waste of the continent for centuries.

  • To do so they have developed extraordinary visual spatial

  • skills, a feature of the right hemisphere.

  • Has the combination of experience

  • and evolution changed the way they think?

  • Aboriginal children do not perform as well

  • as white Australian children on conventional verbal tests.

  • One psychologist, Judy Kearins,

  • thought the tests might be ignoring the Aborigines

  • real skills.

  • >> The children I've found know a great deal more than I do

  • and a great deal more than most white Australian people.

  • They take for granted that we possess most

  • of the knowledge they have, and we don't.

  • They think that a sense of direction is built

  • into everybody's instinct, and also the same thing applies

  • to all their knowledge about the wildlife of their region.

  • They don't really seem to think that any

  • of their knowledge is special and it is very much so.

  • >> Dr. Kearins believes

  • that Aboriginal children use their visual

  • and spatial memories more than white children.

  • She invented a game to test her theory.

  • The task? To remember the positions of a set

  • of objects on a board.

  • The manmade objects should be easier

  • for verbally oriented children to remember

  • because natural objects are not as easily described

  • and remembered in words.

  • Kearins used both natural and manmade objects.

  • >> All right, open your eyes and see.

  • >> The most difficult group of all

  • to describe verbally-- 12 stones.

  • Filimina has 30 seconds

  • to memorize the positions of the stones.

  • She can take as long as she likes to put them back.

  • [ Pause ]

  • >> Okay, very good.

  • Now I'll show you, they're almost all in the right places.

  • That one's right.

  • That one's right.

  • That one's right.

  • That one's right.

  • So is that and that and that.

  • That is. That is.

  • That is. That is.

  • These two should be swapped around.

  • I've been testing aboriginal children between the ages

  • of 6 and about 16 years

  • and they always perform better than white Australian children

  • and also the rate of superiority,

  • if you like, stays about the same.

  • They perform at about the, about three years ahead

  • of the white Australian children.

  • So that an Aboriginal child of about seven years would perform

  • about as well as a 10 year old white Australian child.

  • Not quite as well, but it's about a three year difference.

  • They also tend to perform these tasks

  • in even ways in terms of tempo.

  • They don't hurry and put a few back and then slow down.

  • They seem to perform at the same rate all the time

  • and they also don't mutter or mumble which a lot

  • of white Australian children have done while they were doing

  • the tasks, while thinking.

  • They fix to learn the names hoping that that would help them

  • to remember where the items went.

  • >> The two groups of children use different strategies

  • and perhaps different parts

  • of their brains to solve the puzzles.
