A small group of hunter/gatherers living in the Amazon rain forest is overturning some fundamental assumptions about the mind. Although linguists have long believed that counting and having words for numbers are basic, if not innate, to human cognition, the Pirahã people in Brazil have no words to express numerical concepts such as “one,” “two,” or “many.” “They don’t count and they have no number words,” says MIT cognitive scientist Edward Gibson, who headed a study published in the journal Cognition [pdf].
The researchers spent eight days in a Pirahã rain forest village conducting counting tests on adult members of the tribe. Sometimes the experimenter placed varying numbers of spools of thread on a table and asked the participant to perform a simple one-to-one task, such as laying down the same quantity of uninflated balloons. Other tasks required remembering how many spools had been placed inside a can.
On a related note : I just finished reading Don’t Sleep, There Are Snakes, about an evangelist who goes to live with the Pirahã people (to ostensibly save them/convert them), and it was quite fascinating, eyeopening, and remarkable. The author ends up appreciating their way of life, renouncing his faith and losing friends and family in the process.
