DARPA Working on Spidey Sense for Soldiers

anti-human 1 writes to tell us Wired is reporting that DARPA is developing a new optics system to help soldiers identify threats earlier. "The most far-reaching component of the binocs has nothing to do with the optics: it's Darpa's aspirations to integrate EEG electrodes that monitor the wearer's neural signals, cueing soldiers to recognize targets faster than the unaided brain could on its own. The idea is that EEG can spot 'neural signatures' for target detection before the conscious mind becomes aware of a potential threat or target. [...] In other words, like Spiderman's 'spider sense', a soldier could be alerted to danger that his or her brain had sensed, but not yet had time to process."

Re:Ever hear of the "Sixth Sense"

It is amazing to me how many people do not believe that we have a sixth sense, the ability to know someone is looking at you even though they are not in your field of vision. I have yet to see science explain this...
- I've yet to see anyone come up with a reliable and objective experiment that provided any evidence of a "sixth sense". Science can't explain something that hasn't been empirically observed.

Okay, here's one:

Pick someone, anyone, out of a crowd, on the highway (not recommended if you are driving), etc., from who you are out of their field of view. Stare at them intensely for a few seconds. Direct a strong emotion towards them if you can -- hate, fear, rage, etc. I guarantee you that most of them will look back at you nervously. It may not work for everyone because some people are less aware of their '6th sense' than others.

Funny that. It may seem to the casual starer that more people turn and look at them, but it's simply a case of them subconsciously dismissing the people who don't turn but explicitly noticing the people who do. You might want to look into selection bias for more info on the topic.

Could someone please explain this to me? I've never heard of either concept before.

Humans see principally in three "channels", red, green and blue due to the opsins in your photoreceptors. There is some evidence that some women are tetrachromats however. At any rate, these three opsins give us color discrimination in three mathematical dimensions. However, fish and amphibian eyes are much more complicated than ours. For example, the turtle likely sees in at least seven channels of vision, perceiving a world we could never hope to imagine and here is another fact: In the zebrafish, despite their retinas being much more complex and sophisticated than ours, can repair their retinas from damage whereas we are currently screwed if our retinas go bad.
