Proof Positive That People

Colors With the Tongue
By HENRY FOUNTAIN
When it comes to colors,
the English language is at
no loss for words. Interior decorators and paint
manufacturers, among others,
are constantly coming up
with ever more fanciful
color names.
To linguists, however, all
the sample chips in a paint
store can be categorized
by 11 English words. While
one decorator's buttercup
breeze may be another's
desert bouquet, to a linguist
they are both yellow.
But even 11 is a lot compared
to the Berinmo, a small
tribe of hunter-gatherers
that lives along the Sepik
River in Papua New Guinea.
The Berinmo language
categorizes colors with
just five words.
This makes the tribe a good
subject for studying a
linguistic concept that
first gained wide currency in the
1950's. Called the linguistic
relativity hypothesis, it
argues that humans see the
world less with their eyes
than with their language.
Each language filters
experience differently,
and thus there are no universal
principles of meaning. (In
the most famous explanation
of the hypothesis, Benjamin
Lee Whorf, one of its
proponents, argued that
an Eskimo could never have
just one word for snow,
because of the importance that
different types of snow
have for Eskimo culture.)
Following the hypothesis,
if one people categorizes
color differently from another,
they should perceive it
differently as well.
That's not what researchers
in the 1970's found with
another remote tribe, in
a study that sent linguistic
relativity into something
of a tailspin. The tribe, the
Dani, who live about 200
miles from the Berinmo, have
even fewer words for colors
-- two. Yet in tests, their
ability to remember colors
was much like that of
English speakers. The results
seemed to indicate that
there were some kind of
universal color categories that
transcended language.
Now, three psychologists
in Britain have repeated the
Dani experiments with the
Berinmo, and have come to
the opposite conclusion.
In the study, which is described
in the current issue of
the journal Nature, the
Berinmo were shown samples
from a standard 160-color
chart and asked to categorize
them. In addition to having
fewer categories than
English speakers, the categories
are different. English
speakers, for example, draw
a distinction between blue
and green. Berinmo do not,
but they draw a distinction
within what English speakers
would consider yellow,
with the word "nol" on one
side and "wor" on the other.
The critical part of the
study came when the researchers
asked the Berinmo to remember
colors, by showing
them one sample, waiting
a short time, and then asking
them to match the first
color from two similar
alternatives. Sometimes
the two choices came from
within the same color category,
and sometimes not.
The researchers found that
the Berinmo were much
better at matching colors
across their "nol" and "wor"
boundary than across English
blue and green categories
(after having been shown
the blue-green distinction).
And English speakers, given
the same tests, were
similarly good at blue-green
matches and poor at
matches across the Berinmo
categories.
By showing that color perception
is dependent upon
categorization through language,
the results support the
idea of linguistic relativity,
said one of the authors of
the study, Debi Roberson
of the University of London.
"Berinmo color vision is
the same as ours," said Dr.
Roberson, who came to know
the tribe during nine
months in the jungle. "If
they are asked to identify a
single color from a group
of colors, they would do it in
the same way as you or I.
"But say you have three colors,
and call two of them
blue and one green," she
continued. "We would see
them as being more similar
because we call them by the
same name. Our linguistic
categories affect the way we
perceive the world."
