Rods and Cones
Photoreceptor neurons that process black, white and colors.
Got it
Retina
The retina lines the inside of the eye and is involved with turning light into an image. It contains rods and cones.
Got it
Iris
The term for the colored section of the eyeball. It can contract or expand based on the amount of light around you.
Got it
Cornea
This is the outermost part of the human eyeball and the first part of the eye that light passes through.
Got it
Pupil
A small opening that allows light to reach the lens of the eye. This is the black part in the middle of your eye.
Got it
Lens (of the Eye)
This part of the eye focuses light. The lens is located directly behind the pupil.
Got it
Opponent Process Theory
A vision theory that states that we process colors as 3 sets of opponent colors. This theory is supported by after-images.
Got it
Binocular Depth Cue
Used to help our brain effectively create 3-d images.
Got it
Interposition
This term refers to a monocular depth cue that allows you to determine the relative closeness of two items based on how they overlap.
Got it
Motion Parallax
The perception that things that are closer to you are moving more quickly.
Got it
Retinal Disparity
The effect of having two slightly different images sent to the brain by our eyes. The brain blends this images to craft a 3-dimensional image.
Got it
Aerial Perspective
Aerial perspective occurs when things that are in the distance seem to be foggy.

Flashcard Content Overview

The flashcards in this set go over the body parts associated with vision and hearing. You can review how your body perceives these senses and check out theories related to these senses. Additionally, you'll find cards that focus on depth perception and the state of these senses in newborns.

Rods and Cones
Photoreceptor neurons that process black, white and colors.
Steps in Vision
Light is focused through the lens and moves to the retina. In the retina, rods and cones convert light to electrical signals that can be read by the brain.
Sensation
The ability to receive sensory information.
Perception
Perception deals with your recognition and interpretation of sensory information.
Proprioception
The sense of your body's motion and position in space.
Frequency Theory of Hearing
A theory of hearing that asserts that the neurons of cilia will go off to match the frequency of the sound that enters the ear.
Pinna
The cartilage in the outside of the ear. This is the first structure that sound passes through when entering the ear.
Eardrum
Part of the ear that sits directly against the ossicles.
Ossicles
Tiny bones inside the human ear.
Cochlea
Fluid filled structures inside the ear that contain cilia.
Cilia
Cilia are small fibers that pick up vibrations and create nerve impulses that go to the auditory nerve to help transmit sound information to the brain.
Path of Hearing
Sound moves through the ear in this order: Pinna, eardrum, ossicles, cochlea and cilia.
Newborn Senses
Newborns typically have developed senses of smell, hearing, taste and touch. However, their sense of vision is typically poor, usually only 20/120 to 20/400.
Two senses that are closely related:
Taste and smell. Our sense of taste is greatly influence by our ability to smell.
