Abstract
In the present study we investigated the relationship between visual clutter and visual search in real-world scenes. Specifically, we investigated whether visual clutter correlates with search performance in scenes as assessed both by traditional behavioral measures (response time and error rate) and by eye movements. Our results demonstrate that clutter is related to search performance in scenes. These results hold for both the traditional search measures and for eye movements. The results suggest that clutter may serve as an image-based proxy for search set size in hal-00370577, version 1- 31 Mar 2009 real-world scenes. 2 A critical task in human vision is to locate a sought-after object in the visual environment. In traditional research on visual search, a key variable has been shown to be set size, or the number of items in the display. In search within well-controlled psychophysical displays, set size accounts for a large proportion of the variance in search time (Wolfe, 1998). However, in pictures of natural scenes, it is far more difficult to identify a priori the number of “items ” in the image. In fact, Neider and Zelinsky (2008) have argued that the concept of object-based set size has no clear meaning in real-world
