Theories and Case Studies in Child Language Acquisition
This section explores key theories and case studies in child language acquisition, essential for understanding the principles of language development and preparing for A Level English Language child language acquisition assessments.
Michael Halliday's Language Functions:
- Instrumental: Fulfilling speaker's needs
- Regulatory: Influencing others' behavior
- Interactional: Developing social relationships
- Personal: Expressing preferences and opinions
- Informative: Communicating facts
- Heuristic: Learning and exploring
- Imaginative: Exploring imagination
Highlight: Halliday's functions demonstrate the diverse purposes of language in child development, beyond mere communication.
Case Study: Genie 1970
- Discovered at 13, kept in isolation
- Unable to speak or stand upright
- Father prevented communication
- Never developed fluent speech
Example: Genie's case highlights the critical period hypothesis for language acquisition and the importance of early linguistic exposure.
Berko and Brown's "Fis" vs "Fish" Study:
- Demonstrated children's inability to hear their own pronunciation errors
- Showed correction ineffectiveness in early stages
Nelson's Study:
- Found that excessive correction of word choice and pronunciation in the holophrastic stage slowed language advancement
Major Theoretical Approaches:
- Nativist: Language is innate and pre-programmed
- Behaviorist: Language develops through imitation and feedback
- Social Interactionist: Early language influenced by interactions
- Cognitive: Language growth linked to cognitive development
Piaget's Cognitive Development Theory:
- Children are active learners
- Linguistic development linked to concept understanding
- Certain language concepts can't be taught before cognitive readiness
Berko's Wug Test 1958:
- Tested children's ability to apply morphological rules to novel words
- Demonstrated innate grammatical knowledge
Bruner's Social Interaction Theory:
- Emphasized the Language Acquisition Support System LASS
- Highlighted the role of adult support in language development
Quote: "Children are active learners and their cognitive development is very influential." - reflecting Piaget's perspective on language acquisition.
These theories and studies provide a comprehensive framework for understanding the complex process of child language acquisition stages, essential for A Level English Language child language acquisition model answers.
