•The Language Acquisition Device (LAD) is a
hypothetical module of the human mind posited to
account for children's innate predisposition
for language acquisition.- Chomsky
•Behaviorism suggests that language is an immensely
complex chain of associations and that learning
language is a process of selective reinforcement
(Skinner 1957).
•Two important skills in describing the
development of language in children are :
1.RECEPTIVE SKILL
2.EXPRESSIVE SKILL
THE PRELINGUISTIC PERIOD
•Developmental aspects related to speech would
include the development of gestures, making
adequate eye contact, sound repartee between infant
and caregiver, cooing, babbling and crying.
•Babbling a state in language acquisition during
which an infant appears to be experimenting with
uttering articulate sounds, but does not
yet produce any recognizable words.
The child usually produces a syllable
consisting of a consonant plus a vowel
which often called REDUPLICATION.
REDUPLICATION- is the frequent repetition of
syllabic sounds such as /adadadadada/ or
/mamamamama/ in which the baby engages.
THE HOLOPHRASTIC PERIOD
•at this stage the child only produces one
understandable word at a time when
communicating with adults.
The TELEGRAPHIC PERIOD
•By 18 months the child reaches this stage.
•Child begins to use words in combinations.
•the two-word stage where children would put together
two successive single words
COMMON CATEGORIES OF MEANING (SEMANTIC
RELATIONS) EXPRESSED IN CHILDREN'S
EARLIEST SENTENCES
Semantic Relations Examples
Agent + Action Mommy come ; daddy sit
Action + Object Drive car; eat grape
Action + location Go park ; Sit chair
Entity + attribute Box shiny ; crayon big
Agent + object Mommy sock ; baby book
COMPLEX PERIOD
•the child reaches this stage between the age of two
and two and a half. Grammatical morphemes in the
form of prefixes or suffices are used when changing
meanings or tenses. Furthermore, the child can now
form sentences with a subject and a predicate.
EXAMPLES
“Doggy is big”
“Where is ball?”
“That is not egg”
“I want more sugar”
“I catched it”
“I falling”
