Five groups each one in different ways students learn to make stone Orr Dvorak.
In the first group, the researchers asked students to provide a stone, stone tools, and completion, and tell them all by themselves; in the second group, students simply watch the first person how to make stone, and try to communicate with each other without any copy under the premise of the first individual work; in the third group, you can talk to each other but can not use gestures among students; in the fourth group, you can play the gesture but among students can not talk; but in the fifth set, the “teacher” was allowed to talk to the “student” and said anything.
In each group, the “student” in the next round will be the “teacher.” In this way, the researchers have created five different Orr Dvorak stone “chain of transmission”, and eventually created more than 6000 stone.
Researchers on the “natural communication” Jan. 13 online edition reported that the results were surprising.
The researchers found that, as expected, completely on their own first group achieved only limited success. However, others can simply watch the presentation of the second group has made only limited improvements. Only through gestures or other means to learn to talk the rest of the three groups was a bigger way to create a stone.
The researchers concluded that, even if the earliest stone tools like the ability to successfully spread manufacturing technology in two million years ago, also requires education, and this is the beginning of the spoken language may – Researchers call it the original language. (Some researchers believe that communication is the prelude to oral language gestures, and these tests just to prove its effectiveness.)
