Intro to perception Flashcards
Perception of Movement
Stroboscopic motion:
our tendency to perceive motion in a series of slightly varied still images flashed in rapid succession
Perception of Movement
Phi Phenomenon:
When lights flash at certain speed they tend to present illusions of motion. Neon signs use this principle to create motion perception.
Perceptual Constancy
Perceiving objects as unchanging even as illumination and retinal image change. Perceptual constancies include constancies of shape and size.
Size Constancy
Stable size perception amid changing size of the stimuli.
Size-Distance Relationship - The Moon Illusion
it appears larger and farther away when on the horizon (smaller and closer when up in the night sky).
Size-Distance Relationship
The Ponzo Illusion
when we use background objects to detect an object’s distance.
Size-Distance Relationship - Muller-Lyer Illusion
The line illusion with one line with open end and the other with close end and they are the same length but look different lengths
Ames Room
The room that make you look larger on one end - optical illusion
Sensory Deprivation
Also known as perceptual isolation.

Perceptual Adaptation
Visual ability to adjust to an artificially displaced visual field, e.g., prism glasses. (think about the “drunk googles” you used in driving school)
Perceptual Set
A mental predisposition to perceive one thing and not another… a tendency to perceive or notice some aspects of the available sensory data and ignore other.
What you see in the center picture is influenced by flanking pictures.
Schema
the list of characteristics of an object (concept) that allows us to categorize future, unfamiliar information.
It allows us to know the difference between objects (i.e. chair versus a desk), and they develop through experience.
They influence how we perceive future, unfamiliar information.
Context Effects
A given stimulus can evoke radically different perceptions, based on
the immediate context of the stimulus.
Cultural Context
Context instilled by culture also alters perception.
