The blinking spotlight of attention.
Increasing evidence suggests that attention can concurrently select multiple locations; yet it is not clear whether this ability relies on continuous allocation of attention to the different targets (a "parallel" strategy) or whether attention switches rapidly between the targets (a periodic "sampling" strategy). Here, we propose a method to distinguish between these two alternatives. The human...
متن کاملSplitting the Spotlight of Visual Attention
Can the brain attend to more than a single location at one time? In this issue of Neuron, McMains and Somers report psychophysical and fMRI evidence showing that subjects can attend to two separate locations concurrently and that divided spatial attention leads to separate zones of attentional enhancement in early visual cortex.
متن کاملVisuospatial attention: beyond a spotlight model.
Much of the research in visual attention has been driven by the spotlight metaphor. This metaphor has been useful over many years for generating experimental questions in attention research. However, theories and models of visual selection have reached such a level of complexity that debate now centers around more specific questions about the nature of attention. In this review, the general que...

متن کاملAttending to Features inside and outside the Spotlight of Attention
Previous studies in monkeys and humans have revealed neural correlates and perceptual consequences of feature-based attention. In this issue of Neuron, two brain-imaging studies from Serences and Boynton and Liu et al. bridge the gap between single neurons and behavior by demonstrating a highly functional attention system that acts on neural representations of our visual world enhancing the pro...
