title: Reversible perspective figures and eye movements.
abstract: Eye movements and perspective reversals were continuously recorded on film for 9 subjects who fixated a central point on black line drawings of the Necker cube and Rubin vase figure. There were significantly more Necker cube reversals than Rubin figure reversals in the 1 1/2-min. test periods. Perceptual reversals were unrelated to the occurrence of eye movements but appear possibly to be related to the perceived tridimensionality of the figures.
