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 is a core property of all perceptual and cognitive operations. Given limited capacity
to process competing options, attentional mechanisms select, modulate, and sustain focus …

This tutorial provides a selective review of research on object-based deployment of
attention. It focuses primarily on behavioral studies with human observers. The tutorial is …

The formation of episodic memories—memories for life events—is affected by attention
during event processing. A leading neurobiological model of attention posits two separate …

The cortical reinstatement hypothesis of memory retrieval posits that content-specific cortical
activity at encoding is reinstated at retrieval. Evidence for cortical reinstatement was found in …

When spatial attention is directed toward a particular stimulus, increased activity is
commonly observed in corresponding locations of the visual cortex. Does this attentional …

Recent research suggests imagery is functionally equivalent to a weak form of visual
perception. Here we report evidence across five independent experiments on adults that …

How does attention optimize our visual system for the task at hand? Two mechanisms have
been proposed for how attention improves signal processing: gain and tuning. To …

Visual search is aided by previous knowledge regarding distinguishing features and
probable locations of a sought-after target. However, how the human brain represents and …

How do endogenous (voluntary) and exogenous (involuntary) attention modulate activity in
visual cortex? Using ROI-based fMRI analysis, we measured fMRI activity for valid and …
