speech sound development/Language disorders Flashcards
Sound by 3 yrs old
peanut butter donuts mean no hungry women
sounds by age 4
to kiss guys for yogurt stinks
sounds by age 5
voodoo zoos show llamas chasing jaguars
sounds after age 5
the rs (th voiced and voiceless and r)
morphology
the study of word structure
morpheme
smallest unit of a language
semantics
the study of the meaning in language
overextension vs underextension
overextension is all round items are balls
under extension is only an Oreo is a cookie
quick incidental learning or fast mapping
child’s ability to learn a new word on the basis of just a few exposure to it.
pragmatics
the study of rules that govern the use of language in social situations
Functions of language
labeling: naming something
protesting: objecting to something
commenting: describing or identifying objects
deficiencies exhibited with children with language disorders
limited amount of language
deficient grammar
inadequate or inappropriate social communication
deficient nonverbal communication skills
deficient literacy skills
cognitive deficits
specific language impairment (SLI)
a language disorder in a child who is otherwise typically developing
Characteristics of children with SLI-specific
language
impairment
-often have arctic and phonological problems
-use less complex syllable structures
-overextend/underextend
-have marked morphological problems
-shorter utterances (decreased MLU)
-telegraphic speech
intellectual diabilty
term now preferred to mental retardation. disorder with onset during the developmental period that includes both intellectual and adaptive functioning deficits in conceptual, social, and practical domains. Speech generally believed to be delayed rather than deviant. They follow the same developmental milestones but slower.
autism spectrum disorders
persistent deficits in social communication and social interaction across multiple contexts
Cerebral Palsy (definition and types of CP)
ia disorder where the immature nervous system is affected. A group of sx associated with brain injury in children. occurs due to prenatal, perinatal, or postnatal brain injury. Can manifest paralysis of various body parts.
ataxic CP: disturbed balance, awkward gait, uncoordinated movements (cerebellar damage)
athetoid CP: slow, writhing, involuntary movements (basal ganglia, motor pathways damage)
spastic SP: increased spasticity as well as stiff, abrupt, jerky, slow movements
Types of paralysis
hemiplegia: one side of the body
paraplegia: only the legs and lower trunk are paralyzed
monoplegia: only one limb of a part thereof is paralyzed
diplegia: either the two legs or the two arms are paralyzed
quadriplegia: all four limbs are paralyzed
type token ratio
represents the variety of different words the child uses expressively
discrete trial procedure
shows card
asks questions
immediately models the correct response for he child and asks for imitation
gives praise or corrective feedback
records response
moves onto next trial
expansion
expands the Childs telegraphic speech (doggy bark to yes, the doggy is barking)
extension
the clinician comments on the child’s utterances and adds new and relevant info. (child says play ball and SLP says, yes you are playing with a big, red, plastic ball that bounces)
focused stimulation
usually done during play activity. The SLP repeats the model target (look, here are two pigs, I see two pigs)
The slp does not correct the incorrect responses but does model correct production (e.g., if the kid says I see two duck swimming, the SLP says yes, two ducks are swimming in the pond)
milieu teaching
kid pointing to ball
SLP says what do you want and waits
If child says nothing then model it
praises child then hands over desired object when child elaborates (spontaneously or imitatively)
joint book reading
child participates actively in reading a book. SLP asked questions or when child is familiar with story asks them to fill in information at times.
narrative skills training
working on having the child learn parts of a narrative using tools such as picture cars, books or even videos)
parallel talk
SLP describes what the child is doing during play activities.
recasting
recasting childs productions into longer of syntactically different forms.
self talk
clinician describes her own activity as she plays with the child
articulation approach to therapy
acquisition of individual phonemes and emphasizes speech motor control
phonological approach to therapy
underlying knowledge of the rules of the sound system of language. sound patterns and processes.
Behavioral Theory
based on conditioning and learning. develops speech through interactions with caregiver
natural phonology theory
proposes that natural phonological processes are innate processes that simplify the adult target word. believe that phonological processes are innate or acquired early in life. Suppress processes that do not happen naturally in the language they are exposed to. No evidence to support this.
Prelinguistic devlopment stages
phonation stage (birth-1 month): speech-like sounds are rare. Most sounds are reflexive
cooing stage (2-4 months): most productions are similar to /u/
expansion stage (4-6 months): playing sounds like growls, squeels, yells, raspberries
reduplicated babbling (6-8 months): produces strings of CV syllabes (mama)
nonreduplicated babbling (8mo-1yr): adult like syllabes in CV sequences but varierty of consonants/vowels appear in single vocalization
What age is a child a candidate for intervention if they are unintelligile to listener
3 years old
intelligibility % guidelines for ages
2: 60-70%
3: 75-80%
4: 90-100%
