2.1b Perception: Perceptual Organization and Interpretation

(form perception) Figure-Ground is

is your mind organizing between an

object (the object in forefront) that stand out from its

surrounding (the background in which the object is in

front of).

Grouping

is a perceptual tendency of our

brain to organize things into logical groups.

Gestalt Law of Proximity

states that individual elements that are placed close to each other percieved as belonging together.

Gestalt Law of Similarity

elements that look simillar to each other are grouped together in the mind

Closure Gestalt Principle

human mind seeks to create coherence. will gap in missing images to make a completed image.

Depth perception

ability to see in 3D and allows us to

judge distance.

Visual Cliff

to test depth perception in infants and

young animals. This device lets

us know that depth perception

is innate!

Binocular cues

are depth cues that requires the use

of BOTH eyes. We use binocular cues to judge the

distance of nearby objects.

Retinal disparity

is another binocular cue that comes from the slight difference between the images each of your eyes

see.

Monocular cues

depth cues detected with ONE eye

Motion Perception

brain’s ability to understand when

objects are moving and in which direction.

Stroboscopic movement

an illusion of continuous

movement (as in a motion picture) experienced when

viewing a rapid series of slightly varying still images.

Phi phenomenon

is an illusion of movement created when

a sequence of lights blinks on & off.

Perceptual constancy

is top down process of perceiving

objects as UNCHANGING even as retinal images change.

Color constancy

perceiving familiar objects as having

consistent color, even if changing illumination alters the

wavelengths reflected by the object.

Brightness (lightness) constancy

perceiving an object as having a constant brightness even while its

illumination varies.

Shape constancy

the perception that familiar objects stays constant even when our retinas

receive changing images of them.

Size constancy

the perception that objects have a constant size, even when our distance from them

varies.

Perceptual Interpretation

Our experience guides our perceptual interpretations.

What you’ve never experienced,

you can’t interpret.

perceptual adaptation

is your brain’s ability to adjust to an

artificially displaced or even

inverted visual field.
