Language Acquisition Flashcards
All (normal) human children:
- learn a language.
- can learn any language they are exposed to.
- learn all languages at basically the same rate.
- follow the same stages of language acquisition.
Language Acquisition
the process of building the ability to understand a language and using it to communicate with others.
Innateness Hypothesis
argues that our ability to acquire (human) language is innate (genetically encoded.)
Universal Grammar
refers to the “set of structural characteristics shared by all languages”
Overviews of sign language
- have gesture system
- have morphology rules
- have syntactic rules
- have semantic rules
- have dictionary of arbitrary signs
Theories of Acquisition
- Imitation
- Reinforcement
- Active Construction of a Grammar
- Connectionist Theories
Main Idea of Imitation
Children imitate what they hear
Problems with Imitation
- Children produce things not said by adults.
- Children often fail to accurately mimic adult utterances.
- Children may invent a new language in the right circumstances.
Main Idea of Reinforcement
Children learn through positive and negative reinforcement.
Problems with Reinforcement
- Ignores how children initially learn to produce utterances
- rarely occurs
- fails when it does occur
- fails to explain children’s own grammar rules and why children seem impervious to correction.
Active Construction of a Grammar
- Children invent grammar rules themselves.
- Ability to develop rules is innate.
What active construction of a grammar explains which imitation/reinforcement can’t:
- Children are expected to make mistakes
- Children are expected to follow non-random patterns
- Regression
Connectionist Theories
Claims that exposure to language develops and strengthens neural connections.
Problems with Connectionist Theories
-predicts that any pattern is learnable bu humans, but this is demonstrably false.
Imitation
Is necessary but not sufficient.
Reinforcement
Is virtually unsupported.
