Divided attention and visual search for simple versus complex features
Under what search conditions does attention affect perceptual processes, resulting in capacity limitations, rather than affecting noisy decision-making processes? Does parallel or serial processing cause the capacity limitations? To address these issues, we varied stimulus complexity, set size, and whether distractors were mirror images of the target. Both target detection and localization prod...
متن کاملAttention and Visual Perception: Analyzing Divided Attention
Attention is one of the most active areas of experimental research in cognitive science. This chapter focuses on an aspect of attention that has been studied intensively over the past twenty-five years or so: capacity limitations on our ability to perceive multiple visual inputs. The basic questions are simple but far-reaching. How much visual information can we take in at one time? What can we...
متن کاملSaliency, attention, and visual search: an information theoretic approach.
A proposal for saliency computation within the visual cortex is put forth based on the premise that localized saliency computation serves to maximize information sampled from one's environment. The model is built entirely on computational constraints but nevertheless results in an architecture with cells and connectivity reminiscent of that appearing in the visual cortex. It is demonstrated tha...
متن کاملInvestigating the visual span in comparative search: the effects of task difficulty and divided attention.
In three experiments, participants' visual span was measured in a comparative visual search task in which they had to detect a local match or mismatch between two displays presented side by side. Experiment 1 manipulated the difficulty of the comparative visual search task by contrasting a mismatch detection task with a substantially more difficult match detection task. In Experiment 2, partici...
متن کاملVisual search: psychophysical models, practical applications
Extensive research into the role of saccadic eye movements in human visual perception has been carried out for many years. Although the search patterns of different observers while studying the same image bear some common characteristics, there are often variations in the temporal order in which ®xation points are viewed. During visual search for a de®ned target, there is evidence for both para...
