New York: Japanese
researchers have competed with young chimps against human adults in two tests
of short-term memory, and overall, the chimps won.
That
challenges the belief that “humans are superior to chimps in all cognitive
functions,” said researcher Tetsuro Matsuzawa of Kyoto University.
Professor
Matsuzawa, a pioneer in studying the mental abilities of chimps, and his
colleague Sana Inoue report the results in the latest issue of the journal
Current Biology.
One
memory test included three five-year-old chimps, who had been taught the order
of Arabic numerals 1 through 9, and a dozen human volunteers.
They
saw nine numbers displayed on a computer screen. When they touched the first
number, the other eight turned into white squares. The test was to touch all
these squares in the order of the numbers that used to be there. Results showed
that the chimps, while no more accurate than people, could do this faster.
One
chimp, Ayumu, did the best. Researchers included him and nine college students
in a second test.
This
time, five numbers flashed on the screen only briefly before they were replaced
by white squares. When the numbers were displayed for just four-tenths or
two-tenths of a second, Ayumu was the champ.
Professor
Matsuzawa thinks two factors gave chimps the edge. One, he believes human
ancestors gave up much of his skill over time to make room in the brain for
language abilities. The other factor is the youth of the chimps. The memory for
images required for the tests resembles a skill found in children, which
becomes weaker with age.
