The effect of eye movements and blinks on afterimage appearance and duration.
The question of whether eye movements influence afterimage perception has been asked since the 18th century, and yet there is surprisingly little consensus on how robust these effects are and why they occur. The number of historical theories aiming to explain the effects are more numerous than clear experimental demonstrations of such effects. We provide a clearer characterization of when eye m...
متن کاملEye movements and the afterimage. I. Tracking the afterimage.
INTRODUCTION YARBUS (1967) has claimed that smooth eye movements cannot be made in the absence of a moving visual stimulus. Experiments which apparently contradict this claim involve either a reduction in level of arousal, or some alternative information, or mechanical restraint. Smooth eye movements have been reported at the onset of, and during, sleep (MILES, 1929; DEMENT, 1964; FUCHS and RON...
متن کاملInteractions between chromatic adaptation and contrast adaptation in color appearance
Color appearance depends on adaptation processes that adjust sensitivity both to the average color in the stimulus (through light or chromatic adaptation) and to the variations in color (through contrast adaptation). We explored how these different forms of adaptation interact, by examining how the state of chromatic adaptation depends on the time-varying color contrasts in the stimulus, and co...
متن کاملPerceptually Based Afterimage Synthesis
Afterimages comprise a common, recurring perceptual phenomenon experienced in a daily-basis. Afterimages are best realized when staring at some high intensity light source (i.e., a light bulb) and then shifting the ocular focus to other less luminous portions of the scene: a temporary “ghost” image of that strong intensity remains imprinted on the retina. During the time the afterimage stays ac...
متن کاملAfterimage watercolors: an exploration of contour-based afterimage filling-in
We investigated filling-in of colored afterimages and compared them with filling-in of "real" colors in the watercolor illusion. We used shapes comprising two thin adjacent undulating outlines of which the inner or the outer outline was chromatic, while the other was achromatic. The outlines could be presented simultaneously, inducing the original watercolor effect, or in an alternating fashion...
