特洛克斯勒衰落，即静止图像在持续注视后的感知消失，对于亮度与背景相同的对象来说是常见的。以前的工作表明，微扫视频率的变化是简单刺激(如Gabor斑块)知觉消失和强化的基础。在这里，我们证明了在观看具象艺术时，微眼跳动力学也有助于特罗克斯勒衰落和强化。参与者在观看空白背景上的Gabor补丁或莫奈的画作《印象，日出》时，注视着一个小点。他们不断地通过按下/释放按钮来报告，无论是Gabor贴片，还是莫奈画中的太阳，都是褪色和增强的，同时他们的眼睛运动被高精度地记录下来。微跳率在能见度增加的报告之前达到峰值，在能见度降低或褪色的报告之前下降，无论是在观看Gabor补丁还是在观看莫奈的太阳时都是如此。这些结果表明，微眼跳产生与特罗克斯勒衰落的逆转和预防之间的关系不仅适用于人为刺激的观看，也适用于对《印象，日出》的观察。无论知觉衰退是否是莫奈有意为之，我们的发现表明，观察者的眼球运动动力学是印象派的基石。
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 precision. Microsaccade rates peaked before reports of increased visibility, and dropped before reports of decreased visibility or fading, both when viewing Gabor patches and Monet’s sun. These results reveal that the relationship between microsaccade production and the reversal and prevention of Troxler fading applies not only to the viewing of contrived stimuli, but also to the observation of “Impression, Sunrise.” Whether or not perceptual fading was consciously intended by Monet, our findings indicate that observers’ oculomotor dynamics are a contributor to the cornerstone of Impressionism.
