final exam Flashcards
(104 cards)
general rationale for NBHS
-around 2/1000 newborns will not pass
-more than 90% of children are with HL are born to hearing parents
hearing screening protocol
-auditory brainstem response (ABR)
-otoacoustic emossions (OAEs)
-two tier
-two technology
two tier screening
OAE then onto ABR is OAE if not passed
two technology screening
OAE and ABR testing
types of hearing loss
conductive, sensorineural, and mixed
conductive HL
problem with transmission of sound waves to the inner ear
-CAUSES : fluid in middle ear, otitis media, excess wax, poor tube function
sensorineural HL
results from damage to inner ear or nerve function (inner ear hair cells or auditory nerve)
-CAUSES : genetics, ototoxic drugs, illness, aging, noise exposure
mixed HL
a combination of both conductive and SNHL
types of amplification available
hearing aids, cochlear implants, bone anchored hearing aids, and hearing assistive technology
communication approaches
sign language, speech + sign, cued speech, auditory-oral, auditory-verbal
sign language
assists in language acquisition
-concept level
oral modality
demonstrate higher levels of performance after implantation than children who use total communication
how can hearing impairment affect phonology
-consonant deletion
-vowels are distorted
-prosodic features differ
-intelligibility can be decreased
-challenges with learning phonological awareness skills
how can hearing impairment affect morphosyntax
-simple sentences
-difficulty with morphological development
-expressive and receptive delays
how can hearing impairment affect semantics
-slowed vocabulary development
-concrete words over abstract
-difficulty with multiple meaning words
how can hearing impairment affect pragmatics
-less frequent communication skills
-difficulty with figurative language
-difficulty with topic maintenance
autism spectrum disorder (ASD)
neurodevelopment disorder characterized by deficits in social communication and social interaction and presence of restricted, repetitive behaviors
neurodiversity
term used to describe the concept that brains have natural difference from each other
diagnostic criteria for ASD
diagnostic and statistical manual of mental disorders, fifth edition (DSM-5) made changes to the criteria
DSM-5 criteria for diagnosis
-persistent deficits in social communication and social interaction across multiple context
-restricted, repetitive patterns of behaviors, interest, or activities
-symptoms must be present in the early developmental period
-symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning
- disturbances are not better explained by intellectual disability or global developmental delay
deficits in social interactions are manifested as
-social emotional reciprocity
-nonverbal communication behaviors use for social interaction
-developing, maintaining, and understanding relationships
patterns of behaviors include
-stereotypes of repetitive motor movements
-insistence of sameness, inflexible adherence to routines
-highly restricted, fixated interests that are abnormal in intensity or focus
-hyper or hypo activity to sensory input or unusual interest in sensory aspects of environment
change from DSM fourth edition to fifth edition
DSM-5 calls is autism spectrum disorder with rett syndrome as its own thing
causes that may cause ASD
genetics - hundreds of genes have been associated with autism or syndromes related to autism in recent years
neurobiology - functional connectivity
environmental - parental exposure in toxins, parental and maternal age
