•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).

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.
