Anatomy of the Eye
The eye’s thick, transparent outer layer
What is the Cornea?
These cones are sensitive to short wavelengths that allow the perception of blue
What are S Cones?
The location of rods and cones
What is the retina?
This type of grouping is associated with the closeness of certain objects to one another
What is proximity?
These types of depth cues receive input from both eyes
What are bincocular depth cues?
Part of the eye that flattens and thickens when trying to focus
What is the Lens?
The distinctive characteristic that places a particular color on the spectrum. This allows you to perceive a color as red or blue.
What is Hue?
Approximately, the amount of rods and cones within the retina.
What is about 120 million rods, and 6 million cones?
The forming of an image based off of what parts your brain believes them to "go together"
What is grouping?
This is known as the momentary impression in vision that causes the "waterfall effect", where moving scenery continues to move even after you look away from the object(s)
What is Motion Affereffects?
Bundle of Ganglion cells, that also fires action potentials
What is the Optic Nerve?
This theory proposes that humans perceive color off of three opposing systems.
*Hint: Experiencing the opposing colors allows us to see afterimage effects*
What is the Opponent-Process Theory?
The receptors that are along the retina's edge
Hint: Not in the fovea
What are rods?
This is a form of processing that begins with the conceptual levels of the brain and influences the perception of objects
What is Top-Down Processing?
This term describes the differing views on the retina in each eye
* For example: Closing one eye, looking at an object, then closing the other, and seeing the object slightly shift*
What is Binocular Disparity?
The thin inner surface of the back of the eye. The cornea and lens work to focus light here.
What is the Retina?
This theory states that color perception results from activity from three different types of cones
What is the Trichromatic Theory?
These receptors are responsible for vision under bright conditions as well seeing color and details.
What are cones?
This type of grouping is associated with the tendency to recognize patterns and perceive them as belonging together if there is a consecutive flow
What is continuity?
What is Stroboscopic Motion?
The depression where cones are densely packed along the retina
This is the wavelength of visible light
What is 400-700 nanometers?
These receptors respond well at low levels of light and are responsible for night vision
What are rods?
This form of processing starts with basic stimulus based on properties and perception of patterns
What is Bottom-Up Processing?
This term is used to describe being able to correctly perceive objects in size, shape, color, etc.. across different viewing conditions
*For Example: You can tell someone is tall from far away, you don't have to be up close to know they are tall.*
What is object constancy?
