6. Noam Chomsky ( )
Argues that children have a predisposition to learn language
A person’s brain is hard wired to learn vocabulary and the rules of grammar
“universal grammar”—a basic understanding of the common principles of language organization
At birth, infants can distinguish among the speech sounds of all the world’s languages.
By 10 months, they distinguish only the speech sounds that are present in the language to which they have been exposed.

7. B.F. Skinner and Language
Skinner believed language was the result of learning through:
Association : linking certain sounds with certain people
Imitation
Rewards or punishments

8. Language: Language Stages

9. Encouraging language development: Motherese
People in every culture use a style of speech called motherese, or infant-directed speech, with babies.
Motherese is characterized by distinct pronunciation, a simplified vocabulary, short sentences, a high pitch, and exaggerated intonation and expression.

10. Language Acquisition Stages
In virtually every culture, infants follow the same sequence of language development, and at roughly similar ages.

Babbling
One-Word Stage
Two-Word Stage

11. Cooing and Babbling stage
At about 3 months of age, the infant begins to “coo.”
At about 5 months of age, the infant begins to babble.
Infants all over the world use the same sounds (phonemes) when they babble.
At around nine months of age, babies begin to babble more in the sounds specific to their language.
Will begin to babble only the phonemes of the child’s native tongue at about 1 year of age
Babbling seems to be a biologically programmed stage of language development.

12. One-Word Stage
Long before babies become accomplished talkers, they understand much of what is said to them.
Comprehension vocabulary (the words they understand) is much larger than their production vocabulary (the words they can say).
Around their first birthday, infants produce their first real words — usually referring to concrete objects or people that are important to them
Child uses one word to convey a complete thought or idea
During the one-word stage, babies use a single word and vocal intonation to stand for an entire sentence.

13. Two-Word Stage
Around their second birthday, infants begin putting words together to construct simple “sentences.”
Two word sentences showing an appreciation of the rules of grammar
Children move beyond the two-word stage at around 2-1/2 years of age.
Language production and comprehension increase dramatically thereafter—children may have a production vocabulary of over 10,000 words by school age.

14. Overgeneralization
Child will generalize grammar rules so they apply the rules too broadly.
Example: “I dugged in the sandbox” rather than “I dug in the sandbox”

15. Overgeneralization
