Q

How does the infant’s structures evolve during phonological development?

A

The infant’s larynx, mouth and pharyngeal areas evolve from a mechanism able to serve only production and feeding purposes to a vocal tract that is structurally and functionally ready for the production of speech sounds.

Q

What occurs during respiratory anatomical and physiological changes for phonological development (5).

A
  1. Lungs are large for body structure
  2. Subglottal air pressure is considerable.
  3. Rest breathing for infants is 30-80 breaths per minute.
  4. Around 7 years of age is when children’s respiratory function is adult-like.
  5. Around 10 years of age, rest breathing rate is 17-20 breaths per minute.

Q

What occurs with phonatory and resonatory anatomical and physical changes during phonological development (6)?

A
  1. Larynx and vocal tract in newborns reflect exclusive primary functions (sucking and swallowing).
  2. Arytenoid cartilages are large in infants which limits vibratory action.
  3. Larynx sits closely under the neck and chin which decreases resonance ability.
  4. Production of sound severely restricted.
  5. After the first birthday, expansions of laryngeal and pharyngeal cavity take place.
  6. Vocal folds lengthen

Q

What occurs with articulatory anatomical and physiological changes during phonological development (3)?

A

1.. Larynx and vocal tract in newborns reflect exclusive primary functions (sucking and swallowing).
2. Tongue fills out entire oral cavity
2A: Little space between the gums and cheeks
2B: Sucking pad
2C: Shaping of sounds severely restricted (mostly vowels are produced)
3. After the first birthday, the tongue doesn’t fill the oral cavity because of growth to the skull.
4. Fine tuning and coordination of the articulation occurs.
5. The tongue and lips elongate.

Q

After the first birthday, major changes occur with the infant’s anatomy in terms of phonological development. What might these changes be?

A

Phonatory and respiratoy: Expansions of laryngeal and pharyngeal cavity take place.

Articulatory: The tongue doesn’t fill the oral cavity because of growth to the skill.

Q

How does perceptual development progress from before birth to 4 days old?

A
  1. Begins before birth in the womb.
  2. First days after birth babies demonstrated a preference for the sucking voice and actively changed sucking rate.
  3. 4 day old babies preferred French over Russian
17
Q

At birth, what are the infant’s vocalizations like?

A

At birth, infant’s only vocalization is crying.

18
Q

During the first year, what are a baby’s vocalizations like?

A

The baby moves through non-meaningful cooing to babbling to jargon.

19
Q

Most children can be understood by unfamiliar listeners by what age?

A

3.5 years

20
Q

Most children exhibit adult-like articulation by what age?

A

5 years

21
Q

Summarize what occurs during the first year of phonological development (4 +SA.D).

A
  1. Crying: Nasalizaed vowel sounds made with velopharyngeal port.
  2. Pre-linguistic behavior: vocalizations prior to the first true word (phonological development begins during this time).
  3. Linguistic development: Starts at the appearance of the first words.
22
Q

What has research shown about the first year in phonological development?

A
  1. Babbling is not random but rather the child’s productions develop in a systematic manner.
  2. Consonant-like sounds that are babbled are continuous to a small set of segments.
  3. The transition between babbling and first words is not abrupt bFix this slide
23
Q

What is Stark’s Stage 1 of the Pre-linguistic stages? What age range does it occur in?

A

REFLEXIVE CRYING AND VEGETATIVE SOUNDS

Birth - 2 mos

24
Q

Stark’s Stage 1 (Reflexive Crying and Vegetative Sounds) of Pre-Linguistic stages characteristics (3).

A
  1. Reflexive vocalizations include crying, coughing, grunting, and burps that are automatic responses reflecting the baby’s physical state.
  2. Vegetative sounds are divided into grunts.
  3. Sighs associated with activity include clicks and other noises associated with feeding.
25
Q

Stark’s Stage 2 (Cooing and Laughter) of Pre-Linguistic stages characterisitcs (4).

A
  1. Cooing and gooing are produced during comfortable states.
  2. Although vowel-like, they contain some consonantal elements (back of mouth/nasalized vowels).
  3. Cyring decreases and vegetative sounds start to disappear at 12 weeks.
  4. At 16 weeks, sustained laughter.
26
Q

What is Stark’s Stage 2 of the Pre-linguistic stages? What age range does it occur in?

A
  1. Cooing and Laughter stage

2. Two-four months

27
Q

Segmental productions*

A

Toward the end of the canonical babbling stage, the child produces sounds that are not quite consonants and not quite vowels.

28
Q

Vocoids

A

Vowel-like productions

29
Q

Contoids

A

Consonant-like productions

30
Q

What type of vocoids are preferred?

A

Front and central vocoids

31
Q

When are contoids found?

A

In the late babbling stage

32
Q

What type of syllables are still the most frequent type of syllables during the later babbling periods?

A

Open syllables

33
Q

What types of syllable shapes account for 94% of all syllables produced in these periods?

A
  1. V
  2. CV
  3. VCV
  4. CVCV
34
Q

What type of syllables were found to be very limited in the repertoires of infants?

A

Closed syllables

35
Q

Babbling behavior

A

One aspect of early communication that is emerging as a predictor of later language ability.

36
Q

What was related to later language measures in terms of babbling and language development?

A

Pre-linguistic vocalizations
