Visual Perception issue??

I have a special interest in visual perception and am conducting research on PET scan videos at the moment. If you could take a moment to view the video at

http://www.adronline.org/html2/pet_vid.htm

and say if you see the image moving to his right hand side or his left hand side, I'd appreciate it.  In other words, if you were the image and were to move in the same direction, in which directions would you move?

If you would add whether you are male/female, right or left handed, and under 30, over 40 or in-between, I'd really appreciate it.

I was in the middle of doing other things, and it seemed to change direction depending on when I looked at it... Is this like the spinning lady?

Hi,

-Male

-Rt handed

- now thirty

------------------ The picture? It is swinging - when loads - starts rotating to towards right up to the angle of 45 (clockwise) then it rotates all the way to left to (almost) the 180 from it is stopping position (in anticlockwise direction)!

Now it goes on an on -------------!

 

Interesting but might be incomplete or vague! It should have stopped doing once and there may be start again to repeat.

Best wishes,

mati

ISure.

The figure seems to me to be moving first clockwise and then after a more than 180 degree turn to reverse, and move anti-clockwise.

That help?
