Visual attention is the mechanism the nervous system uses to highlight specific locations,
objects or features within the visual field. This can be accomplished by making an eye …

One longstanding question is how early in the visual system attention exerts its influence.
Here we show that an effect of attention can be measured at the earliest possible stage of …

While the field of vision science has grown significantly in the past three decades, there
have been few comprehensive books that showed readers how to adopt a computional …

Top-down knowledge about the target is essential in visual search. It biases visual attention
to information that matches the target-defining criteria. Extensive research in the past has …

Although previous studies point to qualitative similarities between working memory (WM)
and attention, the degree to which these two constructs rely on shared neural mechanisms …

Acetylcholine is a ubiquitous cortical neuromodulator implicated in cognition. In order to
understand the potential for acetylcholine to play a role in visual attention, we studied …

Visual attention can increase spatial resolution even when it leads to a decrease in
performance. Whether this effect is mediated by reduction of external noise or by signal …

Previous single-unit studies of visual cortex have reported that spatial attention modulates
responses to different orientations and directions proportionally, such that it does not change …

We investigated the mechanisms underlying the effects of sustained and transient covert
attention on contrast sensitivity. The aim of this study was twofold:(1) Using a zero-noise …

According to classical theories, automatic processes are autonomous and independent of
higher level cognitive influence. In contrast, the authors propose that automatic processing …
