A major restoration of Vermeer's "Girl Reading a Letter at an Open Window" revealed a painting of cupid on the back wall that had been overpainted. The uncovering of this painting within a painting changed the composition of the artwork. We performed an eye tracking study on digital representations of the painting to investigate how the restoration altered the way people perceive this artwork. We show that the painting of cupid draws visual attention from the letter and that viewing behavior depends on knowledge of the other version of the painting. Moreover, lay people prefer the version without cupid.

丘比特窃取视觉注意力——维米尔的《在开着的窗户读信的女孩》的修复改变了观看行为。

对维米尔的《在开着的窗户读信的女孩》进行了一次重大修复，发现后墙上有一幅丘比特的画，该画被重新涂漆了。画中画的揭开改变了艺术品的构图。我们对这幅画的数字表示进行了眼动追踪研究，以调查修复工作如何改变人们感知这件艺术品的方式。我们表明，丘比特的绘画从信件中吸引了视觉注意力，并且观看行为取决于对绘画的其他版本的了解。而且，外行人更喜欢没有丘比特的版本。
