To understand visual consciousness, we must understand how the brain represents
ensembles of objects at many levels of perceptual analysis. Ensemble perception refers to …

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 …

We summarize the various strands of research on peripheral vision and relate them to
theories of form perception. After a historical overview, we describe quantifications of the …

This review discusses several pervasive myths about peripheral vision, as well as what is
actually true: Peripheral vision underlies a broad range of visual tasks, in spite of its …

Crowding, the inability to recognize objects in clutter, sets a fundamental limit on conscious
visual perception and object recognition throughout most of the visual field. Despite how …

cope with this severe capacity limitation? One possibility is to use selective attention to …

Recent increased usage of stereo displays has been accompanied by public concern about
potential adverse effects associated with prolonged viewing of stereo imagery. There are …

Humans can recognize the gist of a novel image in a single glance, independent of its

Many experiments have shown that the human visual system makes extensive use of
contextual information for facilitating object search in natural scenes. However, the question …

How does one find objects in scenes? For decades, visual search models have been built
on experiments in which observers search for targets, presented among distractor items …
