Microsaccades mediate perceptual alternations in Monet's "Impression, sunrise".

ABSTRACT: Troxler fading, the perceptual disappearance of stationary images upon sustained fixation, is common for objects with equivalent luminance to that of the background. Previous work showed that variations in microsaccadic rates underlie the perceptual vanishing and intensification of simple stimuli, such as Gabor patches. Here, we demonstrate that microsaccade dynamics also contribute to Troxler fading and intensification during the viewing of representational art. Participants fixated a small spot while viewing either a Gabor patch on a blank background, or Monet's painting "Impression, Sunrise." They continuously reported, via button press/release, whether the Gabor patch, or the sun in Monet's painting, was fading versus intensifying, while their eye movements were recorded with high prec
