Attention 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 کاملDivided 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 کاملDivided attention between simultaneous auditory and visual signals.
Past studies of simultaneous attention to pairs of visual stimuli have used the "dual-task" paradigm to show that identification of the direction of a change in luminance, whether incremental or decremental, is "capacity-limited," while simple detection of these changes is governed by "capacity-free" processes. On the basis of that finding, it has been suggested that the contrast between identi...
متن کاملProcessing efficiency of divided spatial attention mechanisms in human visual cortex.
Many visual tasks require deployment of attention to multiple objects or locations. We used functional magnetic resonance imaging and behavioral experiments to investigate the relative processing efficiency of two putative attentional mechanisms for performing such tasks: the "zoom lens" and "multiple spotlights." Two key questions were investigated: (1) does splitting the spotlight into multip...
متن کاملSelectively Distracted: Divided Attention and Memory for Important Information.
Distractions and multitasking are generally detrimental to learning and memory. Nevertheless, people often study while listening to music, sitting in noisy coffee shops, or intermittently checking their e-mail. The current experiments examined how distractions and divided attention influence one's ability to selectively remember valuable information. Participants studied lists of words that ran...
