CDS 621 - Chapter 2

  1. Nature
    • Plato, Chomsky 
    • also called nativists/rationalists 
    • Language is innate; LAD (language acquisition device) center in brain
  2. Nurture
    • B.F. Skinner
    • Empiricist
    • played a role in piagetian theory  
    • Lang is a function on environment (taught)
  3. 5 Major Theories
    • Behaviorist 
    • Linguists 
    • Constructionists 
    • Social Interactionist 
    • Emergentist
  4. Behaviorist Theory
    • Learning through triggered response 
    • Increase positive behaviors and decrease negative behaviors (stimulus response paradigm)

    Clinical Implications

    • drill and practice activities 
    • focus on observable, measurable behaviors 

    Limitations: not comprehensive theory
  5. Linguistic Theory
    • Language is innate (LAD)
    • apply innate codes to understand language 

    Important concepts

    • phonological rules
    • syntactic categories 
    • phrase structure rules

    **governed by language form
  6. Constructivist Theory
    • Jean Piaget 
    • development of cognition from primitive to advanced 
    • cognitive achievements are linked to linguistic development
    • there are links between motor ability, play behavior, and lang development 
    • Cognitive skill of play: relation between objects and people

    **governed my language content - knowledge to express needs
  7. Social Interactionist Theory
    • Vygotsky and Brunner 
    • interaction plays a role in language acquisition 
    • needs are met by interacting with people
    • child and more capable partner solve problems together, eventually child takes over (zone of proximal development)
    • Match intent to outcome ex) crying pattern gets me food/other wants
    • language  plays critical role in shaping learning and thought 

    **governed by lang use
  8. Zone of Proximal Development
    • Social Interactionist Theory 
    • child solves problem with more capable partner and eventually learn to take over 
    • they will learn when they are ready to learn - when they have  all the necessary unteachable tools 
    • object permanence
  9. Emergenist Theory
    • Blending of the theories
    • nature AND nurture
    • child's biology adapts to the environment 
    • uses computer simulation of lang samples to understand language development 

    Influences clinical work 

    • notes inconsistancies in lang use 
    • note emergent patterns
    • target linguist features to promote system-wide change
  10. 5 Communication Subdomains
    • 1. Early Pragmatics (use)
    • 2. Vocab (content)
    • 3. Early Word Combos (content/form)
    • 4. Morphosyntax (form)
    • 5. Discourse(use)
  11. Early Pragmatic Skills
    • Subdomain 1
    • prelinguistic communication 
    • joint visual attention (10-12 months) - interactive communication
    • 8-15 months: request objects/activities, refusal, comments  
    • 16-23 months: requesting info, answeing questions, acknowledging a response

    Early Discourse (pre-school and up)

    • initiate convo
    • convo exchange 
    • topic maintenance 
    • convo repair
    • code switching
  12. Vocabulary Development
    • Subdomain 2
    • 1 yr old +
    • 200-500 words by 2yrs 

    semantic deficits characteristic of lang disorders in 

    • autism 
    • intellectual disability
    • hearing impairment 
    • specific language impairment
  13. Multiple Word Combinations
    • Subdomain 3
    • Combos occur once speaker has about 50 words 
    • word combos reflect meaning, not structure rules
  14. Morphosyntax Development
    • 24-36 months: children begin to follow form rules 
    • 5 yrs: complex syntax including embedded phrases and clauses
