Week 6: Language Development Flashcards
What is phonology?
The rules governing the structure and sequence of speech sounds eg. discriminating the sound of “ba” and “pa”
What are the 4 components of language?
- Phonology
- Semantics
- Grammar
- Pragmatics
What is semantics?
Vocabulary, the way underlying concepts are expressed in words and word expressions eg. understanding the meaning of “car” in a sentence
What is grammar?
Syntax: The rules by which words are arranged into sentences.
Morphology: The use of grammatical markers indicating number, tense, person, gender etc
What is pragmatics?
Rules for engaging in appropriate and effective communication with others.
What are the 2 theories of language development?
- The Nativist Perspective
- The Interactionist Perspective
What does the nativist perspective suggest?
Suggests that language is a uniquely human accomplishment. That the rules for sentence organisation are too complex to be taught to or discovered by a cognitively advanced young child. That all children have a language acquisition device (LAD)
What is LAD?
An innate system that permits children, once they have acquired sufficiently vocabulary, to combine words into grammatically consistent, novel utterances and to understand the meaning of sentences they hear. Within the LAD, we have a universal grammar, a built-in storage of common rules across all human languages.
What are the 3 main evidences supporting the Nativist Perspective?
- Animals can’t acquire language
- Language areas in the brain
- A sensitive period for language development
Evidence that animals can’t acquire language
Even after years of training of artificial languages and American Sign Language (ASL), common chimpanzees are unable to produce three or more symbol strings that conform to a rule-based structure.
What are the 2 language areas in the brain?
- Broca’s Area
- Wernicke’s Area
What does the Broca’s Area do?
Supports grammatical processing and language production
What does the Wernicke’s Area do?
Involved in the comprehension of written and spoken language
Does the Broca’s Area and Wernicke’s Area work together?
Yes, they actively communicate through nerve fibers
Is language laterised in the human brain?
Yes, language is highly laterised in the human brain. However, the brain is not fully laterised at birth, and it is highly plastic and it develops as children acquire language.
