Kamitani, Y. & Shimojo, S.(2001) Sound-induced visual
"rabbit". Journal of Vision (in press).
Three bars accompanied by a different number of beeps
Fixate to the cross, and press one of the buttons. You may see a different
number of bars with a different number of beeps (especially with "5 beeps"),
whereas the visual stimuli are physically identical.
(This demo may not work on slow computers. If the bar and beep are
not synchronized with"3 beeps", you cannot observe the effect, sorry...)
Three rabbits accompanied by a different number of beeps
Why do we call it sound-induced visual "rabbit"? See Geldard and Sherrick
(1972). But it can be easily made more like rabbits as below :)
