11 totalVisual crowding
A visible object can become hard to recognize when surrounded by other objects. Why does the arrangement of the whole scene change that interference?
Amodal completion
We perceive whole objects even when part is hidden. How does the brain combine visible geometry with knowledge of what the object might be?
Color constancy
An object can look similarly colored under different lighting. How do visual circuits separate surface color from illumination?
Binocular rivalry
When the eyes receive incompatible images, perception can alternate between them. How do eye and pattern competition produce those switches?
Attentional blink
A second target can be missed when it follows another by a few hundred milliseconds. How do processing and response competition create that brief limit?
Motion-induced blindness
A dot can disappear from view while it remains on the screen. A moving pattern around it changes whether it reaches awareness.
