Components of Language
Phonology
Rules about structure and sequence of
speech sounds
Semantics
Vocabulary - words and word
combinations for concepts
Grammar
• Syntax - rules for sentences
• Morphology - grammatical markers
Pragmatics
Appropriate and effective communication
© Allyn & Bacon/ Longman 2007
Three Theories of
Language Development
Behaviorist
Nativist
Interactionist
Learned through operant conditioning
(reinforcement) and imitation
Language Acquisition Device (LAD)
biologically prepares infants to learn
rules of language through universal
grammar
Inner capacities and environment work
together; Social context is important
© Allyn & Bacon/ Longman 2007
Support for Biological
Language Preparedness
• Animal language
 Language seems to be unique to humans
• Brain structures
 Regions predisposed to
language processing
• Sensitive period
 During brain lateralization

Deaf Children’s Language
Deaf children develop language
even when they have:
• Minimal input
 Later than
hearing children,
but do develop
 Homesign
• Inconsistent input
 Extract rules

Language Areas of the Brain
© Allyn & Bacon/ Longman 2007
Interactionist Theories of Language
Development
• Information-Processing Theories
 Statistical learning theory
 Brain studies
• Social Interactionist Theories
 Native desire for
understanding
combines with rich
language environment
© Allyn & Bacon/ Longman 2007
Getting Ready to Talk:
Receptivity to Language
• Newborns sensitive to speech
 Especially mother’s
• Categorical speech perception
 Ability to distinguish phonemes
• Statistical analysis,
rule-learning
• Child-directed
speech
© Allyn & Bacon/ Longman 2007
First Speech Sounds
• Cooing - 2 months
 Vowel sounds
• Babbling - 4 months
 Consonants & vowels
 Universal timing
 Range expands
© Allyn & Bacon/ Longman 2007
Becoming a Communicator
• Joint attention

combinations

Parental Responsiveness
and Language Learning
© Allyn & Bacon/ Longman 2007
Phonological Development
• Early Phase
 First words - can only pronounce few sounds
 Related to semantic development
 Understand more than can say
• Phonological Strategies
• Later development
 Refine syllable stress
patterns - related to meaning
© Allyn & Bacon/ Longman 2007
One-Year-Olds
Know Pronunciations
© Allyn & Bacon/ Longman 2007
Phonological Progress
•
•
•
•
•
Minimal Words
Add ending consonant
Adjust vowel length
Add unstressed syllables
Produce full word, correct
stress pattern
 May still need to refine
sounds
© Allyn & Bacon/ Longman 2007
Early Semantic Development
• Comprehension before production
 5 month lag
• First words linked to
cognition, emotion
• Vocabulary spurt
18-24 months
 Fast-mapping
© Allyn & Bacon/ Longman 2007
Individual Differences
in Language Development
• Gender
• Temperament
• Language environment
• Language Style
 Referential
 Expressive
© Allyn & Bacon/ Longman 2007
Types of Early Words
Object
and
Action
• More objects than actions
• Objects are easier concepts,
parents rarely name verbs
• Influenced by culture & language
State
• Modifiers or labels for attributes size, color, possession
• Learn general distinctions before
specific

Preschoolers’
Semantic Development
•
•
•
•
Underextensions
Overextensions
Word coinages
Metaphors
© Allyn & Bacon/ Longman 2007
Elementary School-Age
Semantic Development
• Big vocabulary increase
 Fast-mapping continues
 Analyze word structure
• Use words precisely,
understand multiple
meanings - metaphors,
puns
© Allyn & Bacon/ Longman 2007
Adolescent
Semantic Development
• Abstract terms
• Sarcasm, irony
• Figurative language
 Proverbs
© Allyn & Bacon/ Longman 2007
Factors Contributing
to Semantic Development
• Adult feedback
• Cognitive processing
 Working memory - phonological store
• Strategies
 Lexical contrast
 Mutual exclusivity bias
 Syntactic bootstrapping
 Social information
© Allyn & Bacon/ Longman 2007
Early Grammatical Development
• Telegraphic speech
 2-word combinations
• Simple sentences
 3 words
 Follow adult rules
piecemeal, gradually
refine and generalize
© Allyn & Bacon/ Longman 2007
Development of
Grammatical Morphemes
• Structural complexity
affects order acquired
• Overregulation
 Applying rules without
appropriate exceptions
© Allyn & Bacon/ Longman 2007
Complex Grammatical Forms
Negatives
Questions
Other Complex
Constructions
• Nonexistence
• Rejection
• Denial
•Rising intonations
•Subject-verb inversion
•Correct yes-no questions precede
wh- questions
• Connectives
• Embedded sentences
• Tag questions
• Indirect object-direct object
• Passive sentences
© Allyn & Bacon/ Longman 2007
Views on Grammar Development
Product of
cognitive
development
• Semantic bootstrapping
• Direct observation of language
structure
• Categories for bootstrapping
Inborn capacities
• Language-making capacity
Environmental
support
• Adults correct indirectly with
reformulations
• Asking for clarification
• Recasts
• Expansions
© Allyn & Bacon/ Longman 2007
Pragmatic Development
• 2-year-olds can have
effective conversations
• Early childhood - turnabout
• Middle childhood
 Shading
 Illocutionary knowledge
© Allyn & Bacon/ Longman 2007
Factors that
Enhance Pragmatic Development
• Adult interactions
 Conversations
 Dialogues about
storybooks, shared
reading

Skills
© Allyn & Bacon/ Longman 2007

Learning Two Languages
Learn both at • No problems with language
the same
development
time
• Good at both by preschool
Takes 3 to 5 years to be as good as
One, then the
same-age native speakers of second
other
language
Both offer cognitive advantages of bilingualism
• Attention, reasoning, concepts, flexibility
• General language skills
© Allyn & Bacon/ Longman 2007
Types of Bilingual Education
• Language immersion
 Strong in Canada
• English-only
 Favored in U.S.
 Risk of semilingualism
• Bilingual education
 Support and instruction in native language
while learning English
