I hope they also sent the participants through new mazes after training while asking them not to echolocate -- just to help determine that they weren't getting better at sightless maze walking for some other reason (like greater sensitivity to signals from the skin and hair) ... It's kind of amazing what information our bodies perceive -- I'm thinking about the phenomenon of walking down the street talking to someone next to you while not looking ahead only to suddenly realize that you've stopped and leaned dramatically backward with your head inches from a sign you didn't see ... I'd love to learn this echolocation skill and then volunteer to help train blind folks that haven't been taught ... I'm obsessed with echolocation.

> I'd love to learn this echolocation skill ... You can quite literally teach yourself. It's not hard in any way. As a _very basic_ start, sometime after dark go and stand a few inches from a wall (facing it). Make a few (fairly loud) clicking sounds with your tongue. Notice what the sound returning from the wall is like. Then step back a pace or two, and to it again. You'll get the hang of "something close in front of me" vs "something 1 meter or two away from me" pretty quickly. Once you've got that, it's pretty easy to expand out the skill set. :)

  Why use tongue clicking rather than your voice?

    Well, I guess you could but tongue clicking works and it gives a fairly precise sound. Maybe try both ways out yourself, and see how it goes? :)
