Chapter 4 Flashcards
abilities present at birth in the human brain
innate
the mechanisms that allow the infant to process and interpret sensory information
innate perceptual abilities
a mental ability that allows the infant to be aware of, perceive and to understand spoken language along with understanding speakers; ideas and feelings.
Processing
Visual perception
sight
Auditory perception
hearing
Gustatory perception
taste
Olfactory perception
smell
infants are able to recognize their mother’s faces at 4 days old because of
innate perception
the ability to perceive and understand sounds that are associated with spoken language, such as intonation
auditory perception
fluctuating or changing vocal pitch: rising and falling, when producing a question or a statement. (by 8 months)
auditory perception
Vegetative sounds such as burping and coughing
Cooing and gooing
Crying, fussing
Syllable shapes may be produced, such as consonant-vowel-consonant vowel (CVCV) forms and vowels (e.g., wawa, ah).
Quasi-resonant nuclei (partial vowel production)
reflexive stage (0-2 months)
Fully resonant nuclei (true vowel production)
Vocalizations with a vowel-like segment are combined with a consonant-like segment
Laughter
Control of phonation (1–4 months)
Isolated vowel production or a series of two or more vowels
Marginal babbling (a series of consonants and vowels or isolated consonants and vowels)
Expansion (3–8 months)
Reduplicated babbling consists of a series of the same consonant-vowel (CV) syllables, such as ba-ba-ba-ba.
Non Reduplicated or variegated babbling consists of a series of different CV sequences, such as ba-bi-bu-bu.
Basic canonical syllables (5–10 months)
Complex syllables such as CV (up), CVC (cat), and CVCC (milk)
Multisyllabic strings with variations in stress or intonation (emphasis on a syllable or changing emphasis on an utterance)
Jargon
Advanced forms (10–18 months)
a syllable series with two different consonants and vowels with changes in stress and intonation, syllables that have the intonational patterns of adult language, such as the pattern of questions or statements
jargon
Infant Production:
There are various stages of development in production
Reflexive stage (0–2 months)
Control of phonation (1–4 months)
Expansion (3–8 months)
Basic canonical syllables (5–10 months)
Advanced forms (10–18 months)
Beginning at about 9 months of age, infants produce consistent vocal patterns that function as words. Often accompanied by gestures. They are used to convey consistent meaning,
These vocalizations are called phonetically consistent forms (PCF)
speech productions that are very similar to adults speech productions in information and rhythm.
Jargon
learning new words through exposure to communicative events, such as conversations.
Incidental learning
where children are purposefully taught a new word.
Deliberate learning
a production that corresponds to the form consistent with a target word produced by adults.
phonemic representations
Two word utterances appear at about ___ months.
