Spatial Conflict Is More than Two People Standing in the Same Place--the Unrecognized Visual Process
"We don't see only what meets the eye. The visual system constantly takes
in ambiguous stimuli, weighs its options, and decides what it
perceives. This normally happens effortlessly. Sometimes, however, an
ambiguity is persistent, and the visual system waffles on which

help us understand how the eyes and the brain make sense of what we see," according to Medical News Today. "Most scientists believe rivalry occurs only when there's 'spatial
conflict' - two objects striking the same place on the retina at the
same time as our eyes move. But the retina isn't the only filter or
organizer of visual information. There's also the 'non-retinal reference
frame'- objects such as mountains or chairs that locate things in
space and make the world appear stable even when our eyes are moving." Read more.
