Ch 6 Articulatory and Phonological Disorders Flashcards
Phonology
This includes broader aspects of speech production and speech perception along wit cognitive-linguistic aspects of the speech sound system.
Articulation
The development and disorders of the speech sound system.
Phonological disorder
A significant deficit in speech production, in speech perception, or in the organization of phonology in comparison to a child’s peers.
Intelligibility
An important functional measure because the goal of speech is communication.
Organic disorders
Attributable to physical conditions such as the inappropriate passage of air through the nose when producing sounds such as /b/ or /s/ in children with a cleft palate of velopharyngeal insufficiency or the omission of consonants at the ends of words because of a hearing loss that precludes hearing these sounds.
Functional disorders
Involve a pattern of speech errors in the absence of any observable physical abnormality.
Phonological levels
This includes the cognitive-linguistic components of the speech sound system. One level includes specific representations of sounds, syllables, words, or phrases either in the form of some acoustic information, based on perception, or in the form of motor plans for speech production.
Phonetic levels
A sub-level of the phonological level.
Diadochokinesis
Rapid alternating movements for certain speech sound sequences.
Tongue thrust
Bringing the tongue against the hard palate and pushing the food or liquid forward, instead of propelling food or liquid toward the back of the mouth. This is how infants and young children swallow.
Developmental apraxia of speech (DAS)
As with adults diagnosed with apraxia, the assumed underlying difficulty involves the sequencing of motor movements to produce speech sounds or syllables. Children identified as having this disorder, however, have not lost any ability due to neurological damage; the disorder is developmental.
Cochlear implants
Surgically implanted devices designed to provide electrical stimulation to the auditory nerve through the cochlea.
Otitis media (OM)
An infection of the middle ear that is often accompanied by fluid, resulting in a conductive hearing loss.
Down syndrome
A complex interaction of motor deficits that affect speech production, perceptual limitations attributable to a very high incidence of chronic OM with effusion along with transient hearing loss, and phonological acquisition that reflects their developmental delay.
New information
Changing aspects of a situation or things that are not known to the listener.
Old information
Static aspects of a situation or things that are known to the listener.
