• How many pegs do you see?
• Can you change your perception to see the other number? Why does this happen?

Perceptiona process of organizing and interpreting
sensory information, enabling us to recognize meaningful objects and events

Perceptual set: a mental predisposition to perceive one thing and not another.
Stare at the dot in the middle. You should see the outer edges of the circle fade away!
Troxler’s fading
It occurs because even if our eyes move a little when we are fixating a point, away from that point, in the perception field, the movements aren’t large enough to observe other elements; in conclusion the neurons remain focused on the main object and our visual system doesn’t involve new ones for the other elements.

'lateral inhibition' - the term used to describe the complex way in which the cells on the back of the retina respond to areas of black and white. There is, however, little point in explaining the theory. Why? Because a few years ago it was shown to be completely untrue, and thus the explanation for the illusion remains a mystery...

Depth Perception
• The ability to see 3D space and accurately judge distances…
Psychology, 4/e by Saul Kassin ©2004 Prentice Hall
• Proximity– Seeing 3 pair of lines in A
• Similarity– Seeing columns of orange
and red dots in B
• Continuity– Seeing lines that connect
1 to 2 and 3 to 4 in C
• Closure– Seeing a horse in D
Perceptual Organization Gestalt Laws of Grouping
Continuity• Continuation – Leads the eye along a path. The
principles of continuation is used to lead the viewers attention to a certain area or to connect an object to a specific action
• Closure – The eyes fill in the missing gaps to make the image/object whole.

Binocular Cues: Depth cues such as retinal disparity that depends on the use of two eyes.
Retinal disparity: Images from the two eyes differ. Try looking at your two index fingers when
pointing them towards each other half an inch apart and about 5 inches directly in front of your eyes. You will see a “finger sausage” as shown in
the inset.
25
Monocular CuesRelative Size: If two objects are similar in
size, we perceive the one that casts a smaller retinal image to be farther away.
26
Monocular CuesInterposition: Objects that occlude (block)
other objects tend to be perceived as closer.

Monocular CuesLinear Perspective: Parallel lines, such as railroad tracks, appear to converge in the distance. The more the lines converge, the
greater their perceived distance.

Perceptual Constancy
Perceiving objects as unchanging even as illumination and retinal images change.
Perceptual constancies include constancies of shape and size.

Size-Distance Relationship
The distant monster (below, left) and the top red bar (below,
right) appear bigger because of distance
cues.
