Failing to see visual objects when attention is directed elsewhere
Change Blindness

A part of the visual field

Visual Cliff
Lab device testing depth perception
Binocular Clues
Depth clues, retinal disparity and convergence, depend on two eyes
Retinal Diaparity
Binocular cue for perceiving depth
Greater = closer and vice versa
Monocular Cues
Depth cues with interposition, linear perspective, available to either eye alone
Relative Size
More distance makes it smaller and vice versa
