Now listen to part of a lecture on this topic in a psychology class.
Just as early humans needed spatial intelligence as they traveled in search of food, spatial skills are still important for people living in Arctic regions today. Because so much of the northern landscape looks so bare and uniform, every visual detail is important. When you have to cross wide spaces and then return home safely, you need a highly developed sense of space.
However, spatial intelligence doesn’t always depend on visual input. Even when people can’t see, they may still have spatial intelligence. For example, a two-year-old girl who was born blind showed amazing ability when she found the right path between two toys—after having walked to each of these toys only from a third location. Even though she’d never taken that path before, she found her way because she recalled the distances of the paths she already knew. She understood the angular relationship of the familiar paths and then used that information to move along the new path. When she was four years old, the same girl was able to use a map that she "read" by touch. Although she’d never used a map before, she immediately understood the concept of a map, including its symbols, and was able to use the map to guide her to the location of a toy in the room.
The professor talks about the movement of people through different spaces. Explain how these examples illustrate spatial intelligence.
