Overall findings:




Average of 20 to 30 thousand words spoken
by each child in a day, from 3 years of age
Daily vocabulary of around 3,000 words
Speed at which they speak ranges from 46.2
wpm to187.5 wpm.
100 wpm at 3 yrs and average of 150 wpm
by kindergarten.

“The acquisition of a first language
is the most complex skill anyone ever
learns. And this task
needs to be virtually complete
by the time a child reaches school
age.”

Pre school language development

Consider overall development

Language growth reflects social, emotional,
cognitive and behavioural development

Critical period for vocabulary and
conceptual development – coincides with
neural plasticity

Language: key concepts:




PRAGMATICS – what language is used for.
SEMANTICS – meaning of the utterance.
SYNTAX – rule system or grammar.
PHONOLOGY – rules governing how the
sounds of a language may be combined.

What is language – Key concepts:

Receptive language – what we understand
– this develops first

Expressive language – what we use

Speech – the sound system used to produce
spoken language

Literacy Development is Based on
Phonemic Awareness
 Phonics
 Reading Fluency
 Vocabulary development

“Literacy begins with speaking and
listening. Adults are so familiar with
these faculties we rarely
acknowledge them as complex,
learned skills, except when
visiting a foreign country.”
(Colin Grigg)
WHY?
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
What is language?

Language is a code

We are continually
cracking the language code

How do we, as adults do this?

Children are actively learning language







Must have joint attention (shared focus)
Must have representational ability (words stand for
things)
Must carry out semantic mapping (work out what a
word stands for)
Must identify words in stream of speech
Must store and retrieve words
Must learn that sharing ideas requires
combinations of words
Must learn rules for combining words (grammar)

PRINCIPLES OF EARLY LANGUAGE
LEARNING

Language is learned through interaction
Petra Smith M.Sc. Aud (C) Sept

Petra Smith M.Sc. Aud (C) Sept

Another Principle:

Human beings are predisposed to learn
language early in life – children are
actively learning their native language
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
More principles of early language
learning:

Patterns are learned
through hearing many
repetitions, rather than
explicit teaching:
“…blow…”

Role of caregiver involves..
Helping the child, as the inexperienced
conversational partner, to want to share
thoughts, ideas and feelings with
confidence and joy. Assisting the child in
taking conversational turns provides the
framework upon which typical language
acquisition develops.

“ A child’s first word has behind it a history

with sounds and highly selective
imitations of people”

Perceiving sounds

Perceiving does not = understanding

Perceiving leads to understanding

Perceiving = Sound-receiving:
“How far back do we have to go?”

Structures of the ear are fully formed in
utero by 5 months. Babies show:
Close to adult sensitivity to sounds
Head turn to sound source (2 days)
Prefer human to non human sounds (2
weeks)
Recognize mothers voice (1 day)
Ability to discriminate fine speech contrasts

More seriously:
“ A child’s first word has behind it a history
of listening, observing and experimenting

Key concept – Hearing Age
Hearing age is calculated in order to
guide our expectations, assessment and
intervention.
Hearing age is the difference between the
child’s chronological age and the amount
of time hearing and learning to listen.
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
Hearing age
A child is identified at birth with a mild
hearing loss. The child is appropriately
aided at 3 months of age and the family
choose to use spoken language.
At two years of age this child’s hearing
age is 21 months.
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
Hearing age
A child is identified at 20 months of age with a
profound hearing loss. Powerful hearing aids give no
benefit and the child receives a cochlear implant at
30 months of age. Spoken language is chosen.
At five years of age the child’s hearing age is 30
months.
His listening and spoken language skills will be
similar to those of a child at two and a half years of
Petra Smith M.Sc. Aud (C) Sept

Petra Smith M.Sc. Aud (C) Sept

First year comprehension:




2 to 4 months – response to different tones
(soothing/playful/angry)
6 to 9 months – responds to familiar
utterances in context (Here’s daddy/Say byebye)
By 12 months – identification of up to 20
word meanings, without visual clues.
Talk embedded in the here and now
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
Making sounds





Birth to 8 weeks – ‘reflexive/vegetative’
noises
2 to 4 months – ‘cooing’ – vowel like sounds
with consonant like sounds.
4 to 6 months – Vocal play – more definite
and controlled; pitch glides.
6 to 8 months – reduplicated babble
8 to 10 months – variegated babble
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
Babbling and early speech..

Avoid clusters of consonants (spr.str)

Vowels occur before consonants

Friction sounds replaced by stops

Characterized by use of stops and nasals

First words – 9 to 18 months



Variegated babble still evident into second year.
More rhythmical and melodic expressive jargon
or ‘scribble talk’.
Appearance of ‘proto words’
First true words are heard
Homophones are used – words sound the same
so meaning is derived from context
Over-generalization – all men arePetra‘daddy’

Comprehension is not reliant upon context
Can talk about outside here and now
Understanding of simple directions grows
2 word sentences begin
Vocabulary grows
Negatives are used
Questions emerge (yes/no; where? whadat?)
Petra Smith M.Sc. Aud (C) Sept

18 to 24 months..

Brief conversations can be held – 2 or 3
turns usually, about familiar or context based
content.

Responses are still limited however, often
leaving the adult feeling as though they are
‘talking to the wall’!

The Third Year




Three, four and five word sentences emerge.
Sentences become more grammatically
correct.
By three
-helping/auxilliary verbs (can/will)
-verb ‘to be’ – ‘am’ ‘are’ ‘is’
Expect many errors with these verb forms
Petra Smith M.Sc. Aud (C) Sept

The Third Year






Articles ‘a’ ‘the’ are used (“That a kitty”)
Negatives ‘can’t and ‘don’t’ appear.
Pronouns develop (“Me want cookie”)
Children begin to ask “Why…?”
Early conceptual understanding is evident –
in/out; big/little; top/bottom; etc..
A number of turns are now taken in a
conversation initiated by the child.
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
3 to 5 Years





Complex sentences are used to link two
ideas (I had a cookie and Toby had two).
‘because’ and ‘when’ are used to link
sentences.
Verbs such as ‘think’ wish’ ‘pretend’ used.
Grammar is more complex.
Normal developmental errors abound (eg:
past tense)

Story telling at 3

Stories (narratives) become a regular part of the
child’s conversation.

Short stories of 1 or 2 sentences occur

They are usually about their own experiences, or
based on known stories.

The child may be unwilling to ‘share the turns’
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
Story telling at 4


Stories are longer – up to 4 or 5 complex
sentences, usually about past events.
The story contains –:
an introduction (“You know what happened to my dog?”)
background (“Well, he was out in the yard..”)
information (“…and he made this big hole”)
ending (“..and he buried my toy tractor!”)
Petra Smith M.Sc. Aud (C) Sept
28/29 2009
Story telling at 5

More details are now provided (“My dog Sam likes to
play in the yard while I have my supper”)

An evaluation or judgement may be made at
the end (“I didn’t play with that tractor any more. I don’t know how
Sam knew that!”)


Imagined stories are more involved – there
are no boundaries!
Predictions and problem solving may be
involved.

Age 6 – Social and linguistic horizons are
rapidly broadening and students are
immersed in a sea of idiomatic and
increasingly abstract language.

Child: “Yes, we’ve got steak.” (Turns to go)
Dad: “Hey, hold on, you can’t rush off like that. If a
customer asks for steak you have to ask him
“How would you like your steak?” That’s very
important if you’re going to be a waitress”
Child: “How would you like your steak?”

High level language

By 7 years of age, children are used to the
idea that with language, things “are not
always what they seem”
To “kick the bucket” doesn’t always mean “to
kick the bucket!”

their own jokes
