Two theoretical ideas have emerged recently with the ambition to provide a unifying
functional explanation of neural population coding and dynamics: predictive coding and …

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 …

In visual search tasks, observers look for targets among distractors. In the lab, this often
takes the form of multiple searches for a simple shape that may or may not be present …

What is attention? How does attention shape consciousness? In an approach that engages
with foundational topics in the philosophy of mind, the theory of action, psychology, and the …

Overt exploration or sampling behaviors, such as whisking, sniffing, and saccadic eye
movements [1, 2], are often characterized by a rhythm. In addition, the electrophysiologically …

Attentional effort relates to the allocation of limited-capacity attentional resources to meet
current task demands and involves the activation of top-down attentional systems in the …

Does our perceptual awareness consist of a continuous stream, or a discrete sequence of
perceptual cycles, possibly associated with the rhythmic structure of brain activity? This has …

In real-life visual environments, where multiple objects compete for processing, new objects
that require immediate attention often appear when attention is already focused elsewhere …
