|
pheripheral system
|
three parts of the ear (outer, middle, inner) and the auditory nerve
|
|
|
central auditory system
|
the pathways to the brain and the brain itself. Starts at the level of the brainstem (PAST the auditory nerve, which is part of the peripheral system)
|
|
|
acuity
|
how well the ear works. Use the word hearing or hearing sensitivity to describe this function.
|
|
|
can there be difficulties with auditory perception without hearing loss?
|
yes
|
|
|
perception
|
how the auditory nervous system works (in total)- works like listening, comprehension, understanding are used to describe this function
|
|
|
auditory attention
|
being aware of and attending to auditory signals for an appropriate length of time
|
|
|
auditory localization
|
ability to determine location of a sound source
|
|
|
auditory discrimination
|
distinguishing similarities and differences between sounds- phonemes and things like pitch, volume, etc.
|
|
|
auditory association
|
ability to match an acoustic stimuli with its source
|
|
|
auditory figure ground
|
ability to differentiate a primary auditory stimulus from other background auditory stimuli (nonlinguistic and linguistic)
|
|
|
auditory analysis
|
aka segmentation. breaking a word up into specific segments- sounds or syllables
|
|
|
auditory synthesis
|
aka sound blending. Ability to blend individual sounds together to form words.
|
|
|
auditory closure
|
filling in missing or distorted acoustic signam over a period of time
|
|
|
auditory sequential memory
|
aka sequencing. A sub-skill/subset of auditory memory. Remembering auditory info in a specific order.
|
|
|
CAPD
|
Central Auditory Processing Disorder. Difficulty in processing and interpreting auditory stimuli in the absence of a peripheral hearing loss usually resulting from a problem in the brain step or cerebral cortex
|
|
|
With CAPD there is a ___________ beyond the auditory nerve
|
breakdown in function
|
|
|
What language dependent areas can CAPD affect?
|
- spelling
- reading - writing |
|
|
What is the range of CAPD symptoms
|
- mild to severe
- may change over time - involve a variety of skills |
|
|
is CAPD more common in males or females?
|
twice as common in males
|
|
|
what % of children are affected by CAPD?
|
2-3%
|
|
|
what % of older adults are affected by CAPD?
|
10-20%
|
|
|
What causes CAPD?
|
- anoxia
- infections - degenerative aging process - intra and extra axial brainstem lesions - brain tumor/abscess - cerebrovascular accidents (cvas) - brain damage from trauma - kernicterus - chronic incidence of OM - congenital defects of the brain |
|
|
kernicterus
|
bile deposits in the central nervous system
|
|
|
can the cause of CAPD be unknown?
|
yes
|
|
|
Is CAPD related to maturation?
|
yes, in some cases
|
|
|
what kind of brain lesions are associated with CAPD?
|
specific and more diffuse lesions
|
|
|
what was the terminology change with regard to CAPD?
|
it is also called simply APD- auditory processing disorder
|
|
|
the population of thsoe with CAPD is highly __________
|
heterogenous
|
|
|
What symptoms/disorders is APD associated with?
|
Learning disabilities, attention deficit disorder, traumatic brain injury
|
|
|
what are the general symptoms of CAPD?
|
difficulty:
- hearing in noisy situations - following long convos - hearing on the phone - learning a foreign language/hard vocab - remembering spoken info - taking notes - maintaining focus if other sounds are present - organizational skills - multistep directions - attention problems - reading/spelling - nonverbal info like music |
|
|
How is CAPD diagnosed?
|
- a specific battery of tests to assess the peripheral and central auditory system:
behavioral tests, electrophysiologic tests, input from other professionals |
