Two People, Two Paths
?
?You must be familiar with the situation: dad’s driving, mum’s telling him
where to go. He’s sure that they need to turn left. But she says it’s not for
another two blocks. Who has the better sense of direction.’? Men or
women?
? ?They both do, a new study says, but in different
ways.
? ?Men and women, Canadian researchers have found, have
different methods of finding their way. Men look quickly at landmarks (地标) and
head off in what they think is the right direction. Women, however, try to
picture the whole route in detail and then follow the path in their
head.
? ?"Women tend to be more detailed. "said Edward Cornell, who
led the study "While men tend to be a little bit faster and a little bit more
intuitive(直觉感知的). "
? ?In fact, said Cornell, "sense of direction"
isn’t one skill but two. The first is the "survey method". This is when you see
an area from above, such as a printed map. You can see, for example, where the
hospital is, where the church is and that the supermarket is on its right. The
second skill is the "route method". This is when you use a series of directions.
Yon start from the hospital, then turn left, turn right, go uphill, and then you
see the supermarket. Men are more likely to use the survey method while women
are more likely to use one route and follow directions. Both work and neither is
better.
? ?Some scientists insist that these different skills have
a long history. They argue it is because of the difference in traditional roles.
In ancient times, young men often went far away with the older men to fish or
hunt. The trip took hours or days and covered unfamiliar places. The only way to
know where you were was to use the survey method to remember landmarks—the
mountains, the lakes and so on.
? ?The women, on the other hand,
took young girls out to find fruits and plants. These activities were much
closer to home but required learning well-used paths. So, women’s sense of space
was based on learning certain routes. |
When finding his way Dad tends to rely on ______.
A:his intuitive knowledge B:his book knowledge C:Mum’s assistance D:the police’s assistance
