Human Echolocation

Yes, that's humans using echolocation to navigate in the world.

It's like a superpower, only for real.
When I was in college, I minored in Psychology, which meant that I got to mostly take the "fun" classes and skip statistics. Though, of course, I took a different statistics course for my major. And, of course, my idea of "fun" may not match up to normal people's idea of what makes psychology fun. The last psych course I took, and my favorite, was Physiological Psychology, and included a lot of study on how our senses worked and fed into our intelligence and the evolution of human intelligence. It was absolutely incredible and, for me, a lot of fun. I've been told that most Psychology majors hated it.
One of the things we talked about, naturally, was intelligence in other creatures. My professor studied dolphins and their intelligence at one point in his undergrad work, so we talked about how their use of echolocation most likely enhanced their relative intelligence. That, and my fascination with bats, let me to write a final paper that involved a LOT of echolocation and how it all worked. All of which is to say that I've read a fair bit about animal echolocation and have always found it interesting. So, you can imagine how excited I was when I saw this article on Boing Boing about human echolocation! Yes! Humans using passive and active echolocation to navigate! It's incredible! And, the video gives you the basics of learning how to do it yourself!
Just the thing to see and try before the weekend!
Seriously, it's real and it's cool and definitely worth checking out!
