From Womb to School

Pre/Postnatal Development
• language acquisition already starts in the womb
• unborn babies have a relatively well-developed
auditory system
• they are able to perceive and recognize their
mother's voice
• by the end of one month, babies are already able to
perceive phonetic differences
• their own production is limited to crying
• first oral communication
• babies are physically not able to articulate “proper”
sounds
• they start cooing (besides crying) - earliest unit of
signaling in the vocal mode
• babies interact with their environment actively
• milestone in language acquisition:
babbling
– occurs between 6-8 months of age
– reduplicative babbling
– dadada
– variagated babbling
– kadabu
• first words
• critical mass
• telegraphic sentences
- function words and grammatical morphemes
The First Three Years
• Characteristics of the stages of language learning:
– predictable patterns in the emergence and
development of many features of the language
that is being learned (depending on the cognitive
development)
– reflection of the gradual mastery of linguistic
elements
Linguistic elements
1.Grammatical morphemes
2.Negation
3.Questions
Grammatical morphemes
1.
2.
3.
4.
5.
Present progressive –ing (Mommy running)
Plural –s (Two books)
Irregular past forms (Baby went)
Possessive ‘s (Daddy‘s hat)
Copula (Annie is happy)
6. Articles the and a
7. Regular past –ed (She walked)
8. Third person singular simple present –s (She runs)
9. Auxiliary be (He is coming)
Why are these grammatical morphemes acquired in
the observed order?
– frequency of occurrence in parents´ speech
– cognitive complexity of the meanings
– difficulty of perceiving/ pronouncing the
morphemes
The ´Wug Test´:
´Here is a wug. Now there are two of them. There are
two _____________.´
´Here is a man who knows how to bud. Yesterday he
did the same thing. Yesterday he _____________.´
Demonstration that children know the rules for the
formation of plural and simple past in English.
systematic development
Negation:
Stage 1: No. No cookie. No comb hair.
Stage 2: Daddy no comb hair. Don’t touch that!
Stage 3: I can’t do it. He don’t want it.
Stage 4: You didn’t have any supper.
She doesn’t want it.
I don’t have no more candles.
Questions:
– predictable order of emergence of ´wh´-questions
1.what
2.where and who
3.why
4.how and when
Acquisition of word order in questions:
Stage 1: Cookie? Mummy book?
Where‘s Daddy? What‘s that?
Stage 2: You like this? I have some?
Stage 3: Can I go? Are you happy? Is the teddy is
tired? Do I can have a cookie?
Stage 4: Are you going to play with me?
Do dogs like ice-cream?
Stage 5: Are these your boots? Why did you do
that? Does Daddy have a box?
Negative Question: Why the teddy bear can’t go
outside?
Embedded Question: Ask him why can’t he go
out?
Stage 6: Able to do all types of questions.
The Pre-School Years
Pre-school development contains several aspects of
language usage:
– Lexis
– Grammatical awareness
– More various usage of language
– Error and mistake rate decreases rapidly
– Metalinguistic awareness
Lexis:
– The rate of vocabulary learning is for three to four
year old children at several words a day
Grammatical awareness:
– At the age of four: most children can ask
questions, give commands, report real events and
create imaginery stories
– They apply grammatical rules correctly and master
basic structures of the language
– Acqisition of more complex linguistic structures
including passives and relative clauses
More various usage of language:
– Usage of language in a wider social environment
– More interaction with unfamiliar adults
– Communication to relatives on the phone
– Awareness of several different “voices“
Metalinguistic awareness:
Metalinguistic awareness describes the ability
to treat language as an object seperate from
the meaning
• Example:
“Drink the chair“
“Cake the eat“
The School Years
• Pre-school language abilities expand and grow
• More sophisticated metalinguistic awareness
(learning to read)
• Vocabulary growth
• Acquisition of different language registers
• Metalinguistic awareness:
– Children learn to read (major boost in language
acquisition)
– Children learn: language has form and meaning (a
word is separate from the thing it represents)
– Discovering of ambiguity
• Vocabulary growth:
– Entering school: hundreds/few thousands of
words can be understood/produced
– Several hundreds to more than 1000 words a year
can be acquired
– More different wordfields are explored (especially
academic language)
• Language registers:
– Children learn:
• How written language differs from spoken
language
• How language differs depending on the social
situation (principal vs. playground)
• How language differs depending on the literary
quality of a text (science report vs. narrative)
• Some children: regional/ethnic language variety
vs. standard variety
