This review focuses on covert attention and how it alters early vision. I explain why attention
is considered a selective process, the constructs of covert attention, spatial endogenous and …

Attention allows us to select relevant sensory information for preferential processing.
Behaviourally, it improves performance in various visual tasks. One prominent effect of …

We introduce functional MRI methods for estimating the neuronal population receptive field
(pRF). These methods build on conventional visual field map** that measures responses …

Does attention alter appearance? This critical issue, debated for over a century, remains
unsettled. From psychophysical evidence that covert attention affects early vision—it …

Does emotion affect how people see? We investigated the effects of emotion and attention,
as well as their conjoint effect, on contrast sensitivity, a dimension of early vision. We …

Computational theories propose that attention modulates the topographical landscape of
spatial'priority'maps in regions of the visual cortex so that the location of an important object …

Conscious perception of the visual world depends on neural activity at all levels of the visual
system from the retina to regions of parietal and frontal cortex. Neurons in early visual areas …

Covert attention, the selective processing of visual information in the absence of eye
movements, improves behavioral performance. We found that attention, both exogenous …

During the last three decades, there have been enormous advances in our understanding of
the neural mechanisms of selective attention at the network as well as the cellular level. The …

Previous investigations of alertness have confounded it with selective attention because
targets were highly predictable. To truly isolate alertness we devised a sparse event-related …
