Simple eye-movement feedback during visual search is not helpful
Searching for targets in the visual world, or visual search, is something we all do every day. We frequently make 'false-negative' errors, wherein we erroneously conclude a target was absent when one was, in fact, present. These sorts of errors can have tremendous costs, as when signs of cancers are missed in diagnostic radiology. Prior research has characterized the cause of many of these erro...
متن کاملPersistence in eye movement during visual search.
As any cognitive task, visual search involves a number of underlying processes that cannot be directly observed and measured. In this way, the movement of the eyes certainly represents the most explicit and closest connection we can get to the inner mechanisms governing this cognitive activity. Here we show that the process of eye movement during visual search, consisting of sequences of fixati...
متن کاملEye movement feedback fails to improve visual search performance
Many real-world searches (e.g., radiology and baggage screening) have rare targets. When targets are rare, observers perform rapid, incomplete searches, leading to higher miss rates. To improve search for rare (10% prevalence) targets, we provided eye movement feedback (EMF) to observers during their searches. Although the nature of the EMF varied across experiments, each method informed observ...
متن کاملMacular degeneration affects eye movement behavior during visual search
Patients with a scotoma in their central vision (e.g., due to macular degeneration, MD) commonly adopt a strategy to direct the eyes such that the image falls onto a peripheral location on the retina. This location is referred to as the preferred retinal locus (PRL). Although previous research has investigated the characteristics of this PRL, it is unclear whether eye movement metrics are modul...
متن کاملEye movement optimization in visual search
In the present study we investigated whether eye movements in visual search are optimized to reduce time on task. Subjects task was to find a target object in a large field of objects that differed based on shape, color, size and numeric label. The target specification was manipulated, directly influencing the average number of fixations it took subjects to find the target object. Although a mi...
