language content =

is the study of word structure

is the study of sentenece structure

the study of meaning of language

is the study of rules that govern language in social situations

the study of sounds

CAMS stands for

the ability to understand spoken language, doesn't require child to speak (pointing)

receptive language is controlled what what area in the brain

the ability to verbally share information or thoughts and emotions

expressive language is controlled by what area in the brain

what is morpheme that usually develops first

child has a goal and how does he achieve that goal

is the structure of language

is the study of word structure

is the study of sentence structure

is the study of speech sounds and how they are used to create the meaning of the word

is the smallest unit of speech that carries meaning and creates a distinction in the meaning (pen vs. pens, intelligent vs. unintelligent)

MLU (mean length of utterances) =

which stage consists of the present progressive -ing (first morpheme) (19-30 months), preposition "in", and regular plural -s (24-30 months)

which stage occurs at 31-40 months and has preposition "on" and possessive -s

which stage occurs at 35-45 months and has articles "the, a, an" (not present in every language)

the rules of sentence structure, such as word order and organization, to form grammatical sentences

which words are more "workable" for children than nouns, as they can "relate" and combine with many other words

when do first (meaningful) words usually occur

is a sound that distinguishes one sound from another (if you change one letter you will get a different meaning "mat" -> "pat")

language use =

decision making, planning, organization, emotional regulation, completing a project/task are all examples of
