Object-based auditory facilitation of visual search for pictures and words with frequent and rare targets.
Auditory and visual processes demonstrably enhance each other based on spatial and temporal coincidence. Our recent results on visual search have shown that auditory signals also enhance visual salience of specific objects based on multimodal experience. For example, we tend to see an object (e.g., a cat) and simultaneously hear its characteristic sound (e.g., "meow"), to name an object when we...
متن کاملDetection of multidimensional targets in visual search
Search performance for targets defined along multiple dimensions was investigated with an accuracy visual search task. Initially, threshold was measured for targets that differed from homogeneous distractors along a single dimension (e.g., a reddish target among achromatic distractors, or a right-tilted target among vertically oriented distractors). Threshold was then measured for a multidimens...
متن کاملRare targets are rarely missed in correctable search.
Failing to find a tumor in an x-ray scan or a gun in an airport baggage screening can have dire consequences, making it fundamentally important to elucidate the mechanisms that hinder performance in such visual searches. Recent laboratory work has indicated that low target prevalence can lead to disturbingly high miss rates in visual search. Here, however, we demonstrate that misses in low-prev...
متن کاملSearch for multiple targets: remember the targets, forget the search.
Models of visual search performance typically assume that search proceeds by sampling without replacement. This requires memory for each deployment of attention. We tested this assumption of memory-driven search using a multiple-target search paradigm. We held total set size constant, varied the number of targets in the display, and asked subjects to report whether or not there were at least n ...
متن کاملThe ultra-rare-item effect: visual search for exceedingly rare items is highly susceptible to error.
Accuracy is paramount in radiology and security screening, yet many factors undermine success. Target prevalence is a particularly worrisome factor, as targets are rarely present (e.g., the cancer rate in mammography is ~0.5%), and low target prevalence has been linked to increased search errors. More troubling is the fact that specific target types can have extraordinarily low frequency rates ...
