Children acquire language through a complex process involving both nature and nurture. They progress through distinct stages of phonological, lexical, and grammatical development from babbling to first words to combining words. Early errors reveal rule-governed learning as children segment words into syllables and master their native language's phonemes and phonological processes. Social interaction provides crucial input, though children can acquire language without full exposure through innate language learning capacities.

Essentiallyhuman
Language itself is very complex
Intricate web of skills
What do children learn?
Sounds and words, meanings and constructions; they need to know what to use, when, where
and how.
Theacquisition mightbe affected byproperties of each Language, as well as bysocial interaction
and cognitive development.
3. TABULA RASA?
Do children have to learn everything aboutLanguage from scratch? Ordothey comewith
certain things already pre wired?
Two theories
NATURE: Any innate capacitiesand
structures children are born with.
NURTURE: What children gain from
experience.
- Even if children areborn with a learning mechanism dedicated to Language, the main proposal
havefocus only onsyntactic structure, the resthas to belearnt.
- Errors madeby over-generalization.
4. Language Differ
Differences: rangeand combination of sounds, for examplesingle consonants to begin syllable
(top), or also combination of consonants (stop); word classes; meanings.
Children find all Languages about equally easy to acquire, butparticular features of one
Language may be more difficult to acquire.
COMPLEXITY
Conceptual complexity: the ideas
being expressedin Language.
Formal complexity: the conceptual
distinctions of each Language maybe
expressed in a variety offorms depending
on the Language.
5. SOCIAL DIMENSIONS
Language acquisition takes place in mid conversation.
When adults talk tochildren they directly orindirectly offer the extensive information about
language. This is called input.

Influencedby threethings:
6. How necessaryis adults speech? Experiments on these topics are difficult if not impossible to
devise, but occasionally a real life situation presents itself in a way that provides a glimpse of the
answers to these questions.
Genie was a child who was not
exposed to any Language while
she was growing up; her parents
locked her away for 13 years
and seldom spoke to her. When
she was discovered, she was
unable to speak. A linguistic
tried to teach her English,but
the attempts were not
successful.
A hearing childof deaf parents who only
use sign language, when Jim was
approximately 3 and ahalf, he had only
small vocabulary that he had probably
picked up from playmates plus a few words
from television jingles. Noadults had
spoken to him directly on any regular basis.
Once Jim was exposed to an adult who
talked to him, his language improved
rapidly.
7. COGNITIVE DIMENSIONS
They have about 12 months of perceptual and conceptual development; they are adept at
perceiving similarities, identifying objects and actions, recognizingfaces, sorting like with like.
They can orient objects and know wherethey are keptand howthey are used. In summary they
are setting uprepresentations of what they seeand know.
Some processesarefoundwithinthe stages thechild goes through:
OVER-GENERALIZATION: The
childtakes agrammatical rule
and applies it to every case.
(From walk,walked to see seed.
Also from dog dogs to man
mans)
OVER-EXTENSION:The child takes the name
of a person or object and names all the things
that look similar to it. (ball, to an apple for
example.)the set of objects named in over-
extensions are as varied and random as those
in complexiveconcepts.
8. Two aspects of general maturationare crucial to a child`s ability to
acquire a Language.1st the ability to symbolize, and 2nd the ability to
use tools.
GOALOF ACQUISITION
The goal is to become a member of a communityof speakers, this
meanslearning alltheelementsof a Language,both structure and
usage.
9. Physiological Prerequisites of
Sound Production
To identify sounds of their language.
To produce each of this sounds and its variants.
To combine sounds into larger strings of sounds (syllables andwords).
To decode larger strings of sounds into syllables and words when being talked to.
When children start to acquire a language,there are various things they
have to learn first:
10. Articulatory gestures involved in producing eachparticular sound.
Thetiming between gestures.
Gain control over the muscles in their speechorgans.
Coordinate the execution of articulatory movements.
First vocalizations
Crying Gurgling Cooing
11. Babbling
Atthe ageoffourtosix monthsorso,childrenin all cultures begin tobabble,producingsequences of
vowelsandconsonants.
Babblinga certainsequenceofsoundsis notaconscious process.

Between abouttenandtwelve monthsofage, children begin toproducea varietyofspeech sounds.
Babbledsequencesarenotlinked toimmediate biological needs like foodorphysicalcomfort.
The finemotormovements necessaryforaccuratearticulationareexercised extensively during
babbling.
13. Phonologicalacquisition
When an eighteen month-old attempts to pronounce the word water,he or she might say
[wa-wa], differences in pronunciation like this may persist for some time.
All children, regardless of what language they are acquiring natively, make mistakes like
these before they have mastered the phonological system of their native language.
Errors reveal that they have already learned a great deal, because the errors aresystematic,
rule-governed, ratherthan random.
Thereis much variation in the age rangeduring which children acquire words or
fundamental cognitive concepts.
14. First words
A major task in the acquisition of phonology involves understanding the wordas a link
between sound and meaning.
Around the age of eighteen months, children learn and ask for many newnames for
objects in theirenvironment.
When children first acquire the conceptof a word, these first words showgreat
variability in pronunciation.
Somemay beperfect adult productions, while others may beso distorted that they are
comprehensible only to the child's closest companions.
15. Acquisitionof phonological structures
Children initiallyregard the entire word as if it were a SINGLE SOUND.
As their vocabulary expands between fifteen and twenty-one months old, it becomes very
difficult for them tomanage.So in order to learn morewords, children must begin to break
words into a small number or SIMPLER UNITS OF SOUNDS.
but
16. Children must acquire the complete set of phonemes as well asthe set of
phonological processes found in the language.
They first master sounds that differ maximallyfrom one another. Often, consonant
-vowel structures such as [ma] and [pa].
This kind of CV-syllable structure appears
to bethe preferred structure in young
children's productions.
Only later will they
produce consonant
clusters such as [sp] or
[tr] as in spill and tree.
17. deletionof consonant and vowel sequences
banana granola potato
Why do children leave out the first syllable in these examples?
In these words the second syllable
is stressed, which means it's the
most prominent syllable in
comparison to the other two
syllables.
When young children listen to speech
being produced around them, there is a
good chance that they willnot pay
attention to those unstressed syllables.
[__n脱na] [__ow] [__dedo]
18. How do children know where one word starts and where it ends in
connected speech?

Onceinfantshavefigured outhowtoidentifythese
prominentsyllables,theyareabletodissect the
continuousstring ofspeech a littleeasier.
However, children tend to unconsciously look for the most stressed syllable and over generalize,
as in the examplesof banana, granola and potato.
19. Theone-word stage
The first words uttered by a one-year
old childtypically name people, objects
and pets. Soon the childincludes verbs and
other useful words like: no,gimme
andmine.
Phrases used by adults become a single word in the speech of
the child, such as: algoneandwhasat?
20. Thetwo-word stage
Between approx eighteen and twenty-four months of age, children begin to use two-word
utterances.
Most of the utterances produced at this stage will express a semantic relation like oneof the
following:
agent+action baby sleep
action+object kick ball
action+locative sit chair
entity+locative teddy bed
possessor+possesion mommybook
entity+attribute block red
demonstrative+entity this shoe
21. Later stages of development
Three-word utterances are originally formed by :
Daddy cookie and cookie
eat, may be combined to
form Daddy eat cookie.
Throw ball, becomes throw red
ball.
22. Plurals

Later,ataroundthe ageofthree, children
begin to usecan,will, andotherauxiliary
verbsin yes-noquestions,using the
appropriatewordorder.
23. interrogatives
Veryyoung children can producequestions using only rising intonation, rather than a particular
syntactic structure. Later, at around three years, children begin to use can, will, and other
auxiliary verbs in yes-no questions, using the appropriate word order.
At this stage, children fail to adult word orderin wh-questions. They follow a question word
with a sentence in normal declarative order:Why you are sad?.
Finally they learnto invert the subject and the verb in these constructions.
