viewer to follow the dialogue and the action of a program simultaneously.

Auditory Processing Disorder (CAPD) - a language disorder that
involves the perception and processing of information that has been
heard. Children with CAPD have problems following spoken instructions
and usually show other language-learning problems, even though the
inner ear is functioning normally.

during ABR testing with children.
cochlea - also called the "inner
ear "; a snail-shaped structure
that contains the sensory organ of hearing and changes sound
vibrations to nerve impulses. The impulses are carried to the brain
along the
cranial nerve, or auditory nerve.
cochlear
implant - a medical device that is surgically implanted and bypasses
damaged inner
ear structures and directly stimulates
the auditory
nerve, helping individuals who have severe to profound hearing
loss to interpret sounds and speech.
Conditioned
Play Audiometry (CPA) - a type of hearing test in which the audiologist
teaches the
child to respond when
a sound
is heard
by playing some type of game. For example, the child puts
a peg in a hole or a block in a bucket every time a sound
is
heard.
conductive
hearing loss - a loss of sensitivity to sound, resulting from an
abnormality or blockage of the outer
ear or the middle
ear. The most common cause of conductive hearing loss
is middle ear fluid
or infection. Other causes include wax buildup in the
ear canal, a hole in the eardrum, or damage to the tiny bones
of the middle
ear.
congenital
hearing loss - a hearing loss that is present from birth and which
may or may not be hereditary.
