  • Again, I can see why the book is the way it is, and why the characters were chosen (to re-enforce the whole 'blindsight' angle, and I'm using blindsight not in its strict meaning, but rather referring to abilities that might be similar in nature to blindsight).

  • Ha! Forgot to check this page/recent comments, thus proving my own point.

    I suspect a gnat's attention span is less than that of a goldfish (famously reported as 3 seconds).

  • Well, that's handy.

    Exactly how long is the attention span of a gnat, anyway? Inquiring minds....

    October 13, 2007

  • I try to worry about everything at once, but I have the attention span of a gnat, so I end up being a niche worrier by default.

    October 13, 2007

  • Oh no! Another niche worrier.

  • Ah, recursion.

  • I think it's highly possible, arby. The brain can do amazing things.

  • Oh, I don't drive. I've had WAYYYYY too many accidents to feel comfortable behind the wheel for long. Although it's been suggested that a complicated system of mirrors could compensate.

    Actually I know a couple people who have mono-vision--that is, their eyes don't function together, which makes it hard for them to perceive distance or see things in 3-D. They both function normally too.

    October 12, 2007

  • OK so I can't prove I have this, but put it this way - I estimate nearly 40% of my right field of vision is not consciously available to me (due to hemispatial neglect) and yet I can function fairly normally. It's either compensation from other parts of my brain, or the visual stimuli is still getting in there some other way.
