Midterm Flashcards
(244 cards)
Why do we care about the typically developing timeline for children?
1) to develop age appropriate diagnostic tests
2) to modify testing as needed
3) to recognize when a child has a delay
What are the three listening elements?
1) Comprehension
2) Retention
3) Response
What are three expressions of language?
1) speech
2) signing
3) writing
What is the cross-model regeneration?
Rewiring of the brain, Some of this can be reversed during early development, brain spurts begin to slow around 1o years (critical period)
Neuroplasticity & hearing
young brains are incredibly neuroplastic- if there’s a lack of auditory stimulation, the brain will try to make up for it with visual information, however, auditory neurons that are not reinforced will begin to atrophy (auditory deprivation)
/b/ and /g/ can be differentiated by ____
2 months of age
Incidental language
children “overhear” speech (reinforcement of language)- happens before oral motor movements for speech and before concepts of language have evolved- starts at birth
Early auditory responses
they are limited and reflexive; eye blinking/widening, sucking paradigms, startle response
which occurs first? localization or lateralization?
lateralization occurs first
Lateralization
right/left, horizontal plane; rudimentary development around 2-3 months, well developed by 6 months; seen in head turn, eye shifts
Localization
exact location in space- can occur in any plane
Auditory Feedback Loop
kids exposed to this at birth, “I hear it”-“I process it and modify it”- “I say it”, example- if you have a cold and you realize you sound different
Hoff 2003: “children who….”
children who hear longer utterances built more productive vocabularies at higher rates
Differences in language development
Socioeconomic status, maternal education- maternal education, aside from SES, is most strongly related to parental measures
Development: Birth-3 months
Auditory: startles to loud sounds, quiets (calms) when spoken to, recognize mom’s voice
Speech: Physiologic sounds (crying, cooing, gurgling), cries for different needs
Developmental: by 2 months baby can grasp objects, smiles, may have separation anxiety
Development 3-6 months
Auditory: responds to changes in tone, notices toys that make noise/sounds, pays attention to music, lateral eye tracking to sounds emerges, mimic vowels toward 6 months
Speech: true babbling begins, may use /p/, /b/, /m/ and vocalizes excitement and displeasure
Developmental: begin eating solid foods, begin sitting upright (~6months)
- Circle of self gets bigger
Development: 6-10 months
Auditory: enjoys games like peak-a-boo, and pat-a-cake; turns and looks in the direction of sound (VRA!)
Speech: Babbling has long and short groups of sounds, canonical (reduplicated)- Uses speech or non-crying sounds to get and keep your attention, uses gestures (holding arms up)- deaf babies will stop reduplicated babbling due to a lack of reinforcement
Developmental: Head and neck muscles strengthen
Development: 9-12 months
Auditory: Listens when spoken to, recognizes words for common objects, begins to respond to simple requests like “come here”, localization instead of just lateralization, recognizes their own name
Speech: Understands “no”, tries to repeat words, may have 1-2 words (mama, dada, hi)
Developmental: first steps
Developmental: 12-17 months
Auditory: attends to toy or book for about 2 minutes
Speech: Follow simple directions accompanied by gestures, answers simple questions nonverbally, points to objects pictures, family members, says 2-3 words labeled to a person or object, tries to imitate simple words
How intelligible is he/she to others? Prime VRA age
Development 18-23 months
Speech/Language: follows simple commands without gestures, points to simple body parts (nose, mouth), understands simple verbs such as “eat”, “sleep”, correctly pronounces most vowels, /n/, /m/, /p/, /h/ especially in the initial position and is beginning to use other speech sounds, says 8-10 words and understands many more
Developmental: beginning to run, walks up and down stairs
*a normal 2 year old will want nothing to do with VRA
Development: 2-3 years
S/L: Knows about 50 words, some spatial concepts (in, on), pronouns such as “you” “me”, “her”, descriptive words such as “big”, “happy”, says about 40 words at 24 months, answers simple questions, speaks in 2-3 word phrases
Before the UNHS… average age of HL ID was…
average age of HL ID was 2.5 years, intervention around 3.5 years
When did JCIH and the UNHS come about
1994!
Main points from Yoshinaga-Itano (1998)
1) children who were early identified and received early intervention maintained language similar to their nonverbal cognitive quotient
2) Later identified kids showed >20 point discrepancies between nonverbal cognitive quotient and language development
* Early ID isn’t worth much w/o early intervention
