Speech sound development/disorders Flashcards
name the theory (of development):
conditioning and learning; CH develops adult-like speech through interactions with CG; babbling shaped into adult forms
behavioral theory
name the theory (of development):
Jakobson, Chomsky, Halle; innate, universal, hierarchical order of acquisition of distinctive features; maximal contrasts /p/ and /a/ then fine tunes them
(Jakobson: discontinuity between babbling and speech development)
structural theory
name the theory (of development):
Stampe; phonological processes are innate processes that simplify adult target word; suppress processes not in own languages
natural phonology theory
perception in infants can be found in what 2 ways?
high-amplitude sucking paradigm and visually reinforced head turn
Oller’s 5 stages of production
phonation; cooing; expansion; reduplicated babbling; non-reduplicated babbling
articulation development in CH
vowels; nasals; stops; glides; affricates/fricatives; liquids; clusters (2 then 3)
class I malocclusion
arches aligned, some teeth misaligned
class II malocclusion
overbite: maxilla protruded, mandible receded
class III malocclusion
underbite: maxilla receded, mandible protruded
lower jaw/bottom teeth in front of upper teeth
name the 2 motor based approaches to SSD
van riper’s traditional approach
mcdonald’s sensorimotor approach
who focused on auditory discrim, phonetic placement, drill like repetition from simple to complex?
van riper
who believes syllable is the basic unit of speech production?
mcdonald (sensorimotor approach)
who has a bottom up drill approach?
both: van riper and mcdonald
who believes context can help shape misarticulated sounds?
mcdonald: phonetic contexts may help a CH with an /s/ distortion- may produce it correctly at end of watch-sun or “tttttttsssss”
who starts with sound in isolation, then syllables, words, phrases, sentences, reading, and conversation… to eventual generalization?
van riper: drill occurs at increasingly complex motor levels in a hierarchy
