Did We Learn Sign Language Before We Learned to Speak?

The idea that humans first communicated by complicated gestures and only later learned to speak is popular among cognitive scientists. Kensy Cooperrider explains

The origin of language is considered one of the hardest problems in science. Like the origin of consciousness, it attracts a great many theories. Cognitive scientist Kensy Cooperrider is a stout defender of the idea that human language started as sign language—a gestural “protolanguage” —hundreds of thousands of years ago. It’s not a new idea. It goes back to Étienne Bonnot de Condillac’s Essay on the Origin of Human Knowledge (1746) and remained popular in the 19th century.

In general, apes communicate more by gesture than by voice. An…

Do we understand the brain better if we see it as a computer?
Seeing the brain as a computer doesn’t tell us as much as we might think. When human beings build computers, we design them in a way that we can understand and use. So we think our brains must be like that too. Sure enough, in the vast complexity of our brains, we can surely find some elements that remind us of a computer. Others won’t.   Read More ›
