are infants rates of syllabic and vocalic vocalizations positively or negatively associated with unilateral communication patterns? | negatively |
What age is the control of articulation? | 5 |
What is the infant doing in the control of articulation stage? | experiment with sounds and loudness of voice. Marginal babbling emerges |
define marginal babbling. | early type of babbling containing short strings of consonant like and vowel like sounds |
what age is canonical syllable stage? | 6 |
What is the infant doing in the canonical syllable stage? | true babbling emerges |
True babbling may be what 2 things? | reduplicated and nonreduplicated |
what is reduplicated babbling? | repeating C |
what is nonreduplicated babbling? | consists of nonrepeating C |
what stage are whispered vocalizations, rounded vowels and high front vowels produced at? | canonical syllable stage |
what age is the advanced forms stage? | 10 |
What is the infant doing in the advanced forms stage? | diphthongs and jargon |
what is jargon? | special type of babbling that contains the true melodic patterns of the native language. |
Jargon are not true words. T or F | True |
What are some foundations that pave the way for later language development? | infant |
What else can infant directed speech be called? | motherese, baby talk, child |
What is infant directed speech? | the speech adults use in communicative situations with young language learners |
What are is paralinguistic features of speech? | the manner of speech outside the linguistic information. |
What features does paralinguistic features of ID speech include? | high overall pitch, exaggerated pitch contours and slower temos. |
What is the syntactic difference between ID and AD? | shorter MLU, fewer morphemes, fewer subordinate clauses more content words, fewer function words |
What discourse features does ID speech have? | more repetition and more questions |
what special purposes does ID speech have? | attract infant attention, infants prefer it to AD, aids in communicated emotion and speakers communicative intent |
ID contains exaggerated vowels or consonants? | vowels |
ID speech highlights content words or function words? | content |
What are the 3 developmental phases for joint attention? | attendance to social partners, emergence and coordination of joint attention, transition to language |
Attendance to social partners is at what age? | birth |
what are infants doing in attendance to social partners? | learning how to maintain attention and be organized within sustained periods of engagement, looking at people's faces |
what age is emergence and coordination of joint attention | 6 months to 1 year |
