I have a right dominant eye.

Extend your arm completely, hold one finger up, with both eyes open align your finger with a distant object, like the corner of a wall. Now close one eye, then open that eye and close the other. Most people should see a major shift in perception from one eye, while the image from the other eye appears relatively the same.

    That is your Master Eye. That's the one you should be using to line up the sights on your rifle.

    I posted this in another thread on AET. If you know the answer, please don't post it, PM me for the answer.

    Watch: http://viscog.beckman.uiuc.edu/grafs/demos/15.html

    Count how many times the people in the white shirts pass the basketball.

    This is an excerpt form Suprising Studies of Visual Awareness
    EDIT: This particular study is not included on the DVD.

    See, if you can see what's wrong with this scene.

    Note, the woman is unaware of the experiment.

    Ok, maybe I'm doing this wrong but my finger hardly moves at all with either eye...

    You have co-dominant eyes then. Lucky you.

    Are you a woman?

    Maybe you have 4 pigments for color as well.

    Cool, women have a chance of having 4 pigements for colour, where as men have a chance of only have 2. So, while men can be color-blind, women can have super color vision.

    I guess that's why women are more fashionable, statistically speaking.

    Cool, I knew there had to be a scientific explanation as to why I have such a keen fashion sense! ;)

    Actually, two of the people switched places as the two men with the board walked in-between.

    The experiment was to see if the people would notice that they were talking to a completely different person, or that the guys clothes had changed.

    Interestingly they don't notice.

    EDIT: Although, some of the people claimed to have noticed, even though they didn't appear to at the time.

    I didn't catch it, and I just showed it to a coworker that didn't catch it. Clearly the subject in the video didn't notice, and to think those guys had different faces and probably different voices as well.

    Here is another example of change-blindness
    http://www.usd.edu/psyc301/Rensink.htm

    There are 3 frames, first frame is unedited, second frame is blank (required), 3rd frame is doctored.

    So the idea is, to see what is different between the first frame and the 3rd frame.

    The 2nd frame is required for the experiment, going from the original photo to the editted photo and the solution is too obvious. With the blank frame, it tricks the eyes.

    So, when you see it cool, please don't post what it is, because it will spoil it, once you know the difference, you will always see it, even a year from now.

    It's a very simple trick, really.

    lol. Yea, it's a relatively large change.

    There are dozens of these change-blindness examples on the internet. They are kind of fun do to, and kind of frustrating.

    Yea, I like that one, there is a full explanation of it, between the Eyes, Visual Cortex and B1 B2 neural networks. The eyes are actually seeing everything in all of these experiments, it's the visual cortex and the connected neural networks that are erroneous.
