Jargon
What is vegetative sounds?
Lip and tongue clicks, burps, coughs. They are associated with feeding and digesting

What is marginal babbling?
Described as the production of a variety of vowel like sounds with occasional vocal tract closure, which together approximate simple consonant vowel (CV) Syllables, as in /ba/, Or vowel consonant (VC). Syllables, as in /ab/
What are fully resonant nuclei?
Sounds that approach consonants, infants’ vowels resonate more fully
What is vocal play?
The longer strings of syllables that expand out marginal babbling as infants continue to “play” with sound
How many phases of babbling are there?
- Marginal babbling
- Reduplicated babbling
- Non-reduplicated babbling
What is reduplicated babbling?
The syllable is duplicated in strings of repetitive syllables
/da-da-da-da/
What is non-reduplicated babbling? Or variegated babbling?
The strings of syllables are more varied. The consonants and vowels may change from one syllable to the next within the same string, as in /gabida/

What is longitudinal research design?
Observe the same infant over an extended period of time
Cross sectional research design?
Collects data simultaneously from separate groups that infants who represent the different developmental ages of interest
Single -Subject experimental design
Interest in how infant behavior might be influenced by certain factors
Prelinguistic communication
What are the three stages of prelinguistic communication
- Perlocutionary Stages
- illocutionary Stages
- Locutionary stages
Prelinguistic communication
What is Perlocutionary stage?
A phase in which communication is based primarily on caregivers interpretation infants’ behavior
Prelinguistic communication
Illocutionary stage
