Part of eye that
stretches or thickens
depending on how
far away an object is
lens
What does the length of
a light wave tell us?
What does the height
(amplitude) of a light
wave tell us?
Length: Color
Height: Brightness
Place where your
vision is the best
fovea
Explain how your
pupil and iris work
together
Work together to
determine how much
light enters the eye – Iris
expands when dark,
contracts when bright
Name the three layers
of cells that make up
the retina (in order!)
Receptor cells (rods
and cones)
Bipolar cells
Ganglion cells
Main organ of your
ear
cochlea
What does the
frequency of a sound
wave indicate?
Height (amplitude)?
Frequency: pitch
Height: loudness
Name the parts of
the outer ear
Auditory canal,
tympanic
membrane
What are the names
of the three bones in
your ear?
Bones of your
middle ear;
hammer, anvil,
stirrup
Your receptor cells in
your ears are called….
Hair cells
Taste and smell are
what kind of senses?
chemical
Taste and smell combine
to make...
flavor
The smell center of
your brain is…
Olfactory Bulb
Name the four basic
senses your skin
receptor cells can detect
Pain, warmth, cold,
and pressure
Name your 2 body
senses and what they
control
Kinesthetic sense: provides
information on your body’s
position and movement
Vestibular: provides info
about your overall
orientation
What type of
processing does
perception use?
Top-down
What is a figure
ground
relationship?
Our brains organize
our visual field into
objects (the figure) that
stand out from their
surroundings (the
ground)
Name the 4 grouping
principles
Similarity, proximity,
closure, continuity
What is a visual
cliff and why is
it used?
Name and explain your
2 binocular depth cues
Retinal Disparity: depth cue
that results because of
different images on retinas
Convergence: eye muscle
tension
What are illusions
and why do we use
them?
Misinterpreting sensory
stimuli
Helps us understand how
sensation and perception
normally work
Name and explain 3
monocular depth cues
relative size; motion
parallax;
interposition; relative
height; texture
gradient; relative
clarity
Explain the
illusion of
stroboscopic
motion
Quickly viewing a
series of slightly
different images
Explain the phi
phenomenon
Creates the illusion
of movement when
lights are turned off
and on in a sequence
Perceptual sets are
guided by _________
Schemas
What is an
absolute
threshold?
Minimum amount
of stimulation a
person can
normally detect
What is sensory
adaptation and
give an example
When we filter out
the unchanging
aspects of our
environment
What is selective
attention?
Ability to focus on one
stimulus
What is perceptual
constancy?
Perceiving the size,
shape, and lightness of
an object as
unchanging, even as
the retinal images of
the object changes
What are the functions
of the cornea?
Focus light by
bending it and
protects eye
