Innate vs. learned

Are we prewired for language?
Or are we just smart and good at finding
patterns in language (and everything else
too)?

Child Directed Speech
●
Example
Child Directed Speech
●
Phonetics:
–
special pronunciation of certain words (wabbit
vs. rabbit)
–
higher pitch
–
greater range of frequencies
–
slower rate of speech
–
clearer enunciation
–
emphasis on one or two words
Child Directed Speech
●
Grammar:
–
reduction or non-existence of inflections
–
the use of an all-purpose auxiliary: English
make, go
–
avoidance of first and second person
pronouns (Baby is finished? or Mommy is
coming)
Child Directed Speech
●
Grammar:
–
reduction or non-existence of inflections
–
the use of an all-purpose auxiliary: English
make, go
–
avoidance of first and second person
pronouns (Baby is finshed? or Mommy is
coming)
–
omission of the copula
–
more grammatically correct usage
–
more grammatically simple phrases
–
shorter phrases
Child Directed Speech
●
Vocabulary:
–
set of words very small: 100 –150 words in
many languages
–
semantic fields: kin, body, qualities, animals,
food and games
–
substitutions
–
diminutives
–
use of child's own forms
Child Directed Speech
●
Conversational features
–
more restricted topics
–
more repetitions
–
more questions/fewer declaratives
–
repetitions, expansions, recasts

What percentage of each in CDS?
Child Directed Speech
●
Does CDS help learning?
●
or should you speak to kids like adults?
Child Directed Speech
●
Gestures
–
Main finding: gesturing by parents leads to
gesturing by infants which leads to
•
•
•
•
Vocabulary use at 1;2 years
Vocabulary growth over time
Scores on the Peabody Picture Vocabulary Test
(PPVT) at 2;5 years
children who use gesture put words together
faster
Child Directed Speech
●
Intonation
–
CDS intonation has been found to help
•
•
•
Word segmentation
Understanding of complex syntax
Interest in the speech
Child Directed Speech
●
Lexicon
–
Parents who heavily use CDS have children
with larger vocabularies and faster vocabulary
growth over time .
–
These children also end up having better
reading comprehension abilities at age 10
Child Directed Speech
●
Syntax
–
Children whose parents use less complex
syntax, can learn syntax better
Child Directed Speech
●
Pragmatics
–
CDS interactions can encourage the child to
think of language as a social interaction, which
involves turn-taking and politeness routines.

So is language taught or not?

So is language taught or not?

If so, then it may not be innate

●
What affects use of CDS?
–
Socioeconomic status
–
Gender
–
Race
Child Directed Speech
●
Socioeconomic status
–
Less advantaged parents tend to talk less and
use less varied vocabulary with their children
Child Directed Speech
●
Gender
–
Fathers have more difficulty comprehending
their children‟s speech
–
Fathers tend to talk less when interacting with
children, and use more directives, which
indicates a more authoritarian style
–
Fathers are thought to use more
“sophisticated” lexicons with children than
mothers
Child Directed Speech
●
Gender
–
Interaction with mothers typically involves
caretaking activities, whereas father-child
interaction is predominated by play activities
–
Fathers have shorter mutual dialogues with
their children
–
Fathers respond less frequently to a child's
requests
Child Directed Speech
●
Socioeconomic status
–
Use of rare words (less frequent)
•
•
•
professional class parents used more rare terms
than working class parents
professional class fathers used more rare terms
than mothers
working class fathers used fewer than working
class mothers.
Child Directed Speech
●
Socioeconomic status
–
Use of interrogatives
•
•
•
Professional class parents used more question
words than working class parents.
Professional fathers used more question words
than professional mothers
Working class fathers used fewer question
words than working class mothers
