Eye Spy
What is the cornea?
The process by which the eye's lens changes shape to focus images of near or far objects on the retina
What is accommodation?
A coiled, bony, fluid filled tube in the inner ear
What is the cochlea?
a tone's experienced highness or lowness; depends on frequency
What is pitch?
processing multiple aspects of a stimulus or problems simultaneously
What is parallel processing?
The adjustable opening in the center of the eye through which light enters
What is the pupil?
the dimension of color that is determined by the wavelength of light
What is hue?
The chamber between the eardrum and the cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochlea's oval window
What is the middle ear?
The most common form of hearing loss, caused by damage to the cochlea's receptor cells or to the auditory nerve
What is sensorineural hearing loss?
information processing that begins with the sensory receptors and works up to the brain's integration of sensory information
What is bottom-up processing?
A ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening
What is the iris?
the amount of energy in a light wave, which influences what we perceive as brightness.
The cochlea is found here
What is the inner ear?
A less common form of hearing loss, caused by damage to the mechanical system that conducts sound waves to the cochlea
What is conduction hearing loss?
The conversion of one form of energy into another
What is transduction?
the light-sensitive back inner surface of the eye and contains layers of neurons that begin the processing of visual information
What is the retina?
The theory that the retina contains three different types of color receptors
The auditory nerve carries the neural message to this point
What is the Thalamus?
A device for converting sounds into electrical signals
What is cochlear implant?
the minimum stimulus energy needed to detect a particular stimulus 50% of the time
What is absolute threshold?
these detect black, white and gray and these detect fine details and give rise to color sensations
What are rods and cones? (in that specific order)
I determine hue and I determine intensity
What is wavelength and amplitude? (in that order)
the three parts of the inner ear
What are the cochlea, the vestibular sacs and the semicircular canals?
the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated
What is place theory?
The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount)
What is Weber's Law?
