Language Acquisition


Munira Jamal, 28 January 1998

General Statements about the Human Language


* Rule-governed and creative
* Human linguistic capacity is unique

Stages in Language Acquisition


Infants' First Sounds

Babbling

* (Begins at around 5-6 months and lasts for some 6-8 months)
* Meaningless sounds
* Sounds are already `language-like'

The One-Word Stage (`one word = one sentence stage')

* (Late part of the 1st year or the early part of the 2nd year)
* Holophrastic `sentences' are produced
* Words indicating names (mama, doggie), certain actions, demands (more! no!)
* Undergeneralization
* Overgeneralization

* `Rich interpretations' from the parents' side
* Child's utterances don't necessarily mean what adult utterances mean
Possible conclusion:
Child uses language for social purposes, tries to convey ideas and feelings

The Two-Word Stage

* (At some point during the 2nd year of life)
* The beginnings of a structured language (Engl.: subject + predicate structure)
* Two-word sentences with clear syntactic and semantic relations
* No inflections for number, person or tense

From Telegraph to Infinity

* Development of language in more detail
* Two, three, four, or five words or longer
* Sometimes called `telegraphic speech', because only `content' words occur
* The words appear to be `sentence-like'

Theories of Child Language Acquisition


Two extreme positions
The extreme environmentalist position:
* Lingustic behavior is shaped gradually
The extreme innateness position:
* Infants are born with knowledge of the basic grammatical relations/ categories
* This knowledge is universal

* Language Acquisition Device (LAD)
* Universal Grammar (UG)

Do Children Learn by Imitation?


Child:


I taked a cookie.


Parent:


Oh, you mean you took a cookie.


Child:


Yes, that's right, I taked it.



Conclusion
Imitation can only be involved to some extent; therefore it's not the decisive concept; anything the child ist not yet ready for, it simply ignores

Do Children Learn by Reinforcement?


Child:


Nobody don't like me.


Mother


No, say `Nobody likes me.'


Child:


Nobody don't like me.



(repeated eight times)


Mother:


Now, listen carefully, say `Nobody likes me.'


Child:


Oh, nobody don't likes me.
