I simply can't get her to do anything but go clockwise. I see exactly how the illusion works, but the "fast" part of her motion (when she's facing toward or away, regardless of how you see her rotating) always fixes it in my head to be clockwise.
However, I'm quite strongly "left-brained" -- I'm right-handed, interested in the analytical aspects of music, mathematical, scientific -- though I do have plenty of more stereotyoically "right-brained" traits. However, to prove how "left-brained" I am: Facts rule. Evidence is essential. This so-called test is bunk as far as i'm concerned until I see a shred of evidence to support it. 😛
