What is interposition

A)  a lens's ability to change shape and focus light directly on the retina 
B)  the processing of auditory information at the cochlear level 
C)  an environmental depth cue in which closer objects overlap objects farther away 
D)  the relationship between bipolar and ganglion cells

Interposition

A visual cue in depth perception where objects that block the view of other objects are perceived as being closer.

Environmental Depth Cue

Visual or other sensory cues in one's environment that provide information about distance and three-dimensional space.

Bipolar Cells

A type of neuron found in the retina that acts as a middle layer transmitting signals from photoreceptors to ganglion cells.
