Flashcards in Closer look at vocabulary Deck (29):
What is fastmapping?
Children map novel words onto novel objects in the presence of other familiar objects
What is domain-specific?
Unique language mechanism at work underpinning children's acquisition of vocabulary
What is domain-general?
Children make use of general learning mechanisms to acquire vocabulary, rather than having specific 'machinery' for learning language, e.g. from memory, learning, executive function
What is semantic feature analysis?
A word map tool used in clinical practice to help children and young people develop semantic connections
What is boot-strapping?
This is a process whereby you can create something more complex and effective using your existing resources, or use existing strengths in one area to help you understand or learn something in other domains.
Compensates for deficits in other domains
What is semantic boot-strapping?
Semantic knowledge helps the child pick out recurring phonological forms
- depends on shared focus of attention
- verbs are hard to learn as they are transient
What is phonological boot-strapping?
If the child hears a phonological form with which they are unfamiliar, they will search for the meaning it is attached to
For example, children assign masculinity/femininity depending on the name rather than cues from the pictures
What is syntactic boot-strapping?
The reverse of semantic bootstrapping
Some knowledge of verb-argument structure is required
Use own knowledge of sentence structure to decipher what action the word is referring to
What are the mechanisms of word learning?
Attention and Learning
What is input?
The rate and manner in which children acquire words is affected by the way their parents talk to them
What is syntax?
Predicting word meaning from assumed word class due to position in sentence
What are lexical constraints?
Whole object bias: words refer to whole objects, not parts or features
Taxonomic bias: words refer to kings of things, not individual things
Mutual exclusivity bias: every object can only have one name
One constraint will win over another
What is attention and learning?
Children's word learning is influenced by what they pay attention to
A product of associative learning
Principally pay attention to an object's shape, rather than it's colour, material or size
What is conceptual bias?
Word acquisition builds on the constructs the child has created about the world - children form a hypothesis about a word's potential meaning
Inanimate object = children map the noun to a subordinate category
Animal = interpret label as a proper name
What is pragmatics?
Children work out patterns in speakers' interactions with them - intentionality
Tomasello - children learn linguistic structures through intention-reading and pattern finding
What is code-switching?
Enhanced executive control, or the ability to effectively manage higher cognitive processes such as problem-solving, memory and thought
What is the interactionist perspective based on?
Learning about language starts well before the first words appear
Emphasises the semantic aspect of language
Purpose behind a child's learning to speak is to get meaning across
Agent-action constructs used when realisation of actors becomes apparent
What is social context by Halliday and Bates?
Emphasised the pragmatic aspect of language - language in use/as a social behaviour
What is the language acquisition support system?
Caregivers support their children's linguistic development in social situations until the child learns to take a more active role in social situations - child-directed speech
What is the social-pragmatic approach by Tomasello and Aktar?
The most important factor is social communicative dimension
Use own understanding of situation to focus attention on same entity
Aware of others as intentional agents
What is the model of intentionality by Lois Bloom?
Focuses on the child as being an active agent in word learning process
Dislikes idea of LAD
Shifts focus of language learning to child
Joint attention which child determines
Also acquire relational words in single-word stage
What is the principle of relevance?
Language learning is enhanced when the words a child hears are pertinent to objects/people around them
What is the principle of discrepancy?
Language is needed when a child realises the discrepancy between what they and others have in mind
What is the principle of elaboration?
Children need to learn increasingly more elaborate language to express increasingly more elaborate contents of mind as the child develops
Provides impetus for propelling language learning
What are the errors in word learning?
What is overextension?
Child uses one word to mean many objects
What is underextension?
Child uses one word to specifically mean one object
What is idiosyncracy?
Talking about something that isn't there
