Sensation & Perception; Psychology Monocular and Binocular cues

Interposition:

visual signal that an object is closer than the ones behind it because the closer object covers part of the farther object.

Relative Size:

2 objects that are usually similar in size, the smaller one is further away

Relative Clarity:

hazy objects appear further away

Texture Gradient:

coarser objects are closer

Relative Height:

things higher in our field of vision look further away

Linear Perspective:

paparallel lines converge with distance (think railroad tracks

Retinal Disparity:

the fact that the left and right fields of vision provide slightly different visual images when focusing on a single object.

Convergence:

the ability to turn the two eyes inward toward each other to look at a close object.

TOP-DOWN PROCESSING:

pre-existing knowledge and context to guide the understanding and execution of the task.

BOTTOM-UP PROCESSING

taking in sensory information and processing it to form a coherent understanding of the task at hand.
