Lecture 6- Language Acquisition Flashcards
Learning language involves which skills
- Association
- Generalisation
- Recognition
- Retrieval
Language acquisition uses
Domain general skills
A lot of language acquisitions is
Learning patterns
Comprehension precedes
Production
What is comprehension
Understanding what others communicate
What is production
Communicating to others
Middle and high socio-economic status (SES) are more
Talkative
Children with more talkative caregivers learn
New words faster
At 18 months old children from low socioeconomic status (SES) backgrounds produce
Fewer words
Children from low socio economic status (SES) backgrounds produce
Less complex sentences
By 24 months there is how much of a gap between socio economic status (SES) groups
6 month language gap
Foetuses can hear from
15-18 weeks
What is cadence
The rhythm of language/ speech
How do infants know where the breaks are
- Pitch
- Pauses
8 month old infants could distinguish between
Words and part words
Infant directed speech exaggerates
Differences between vowels
7 month infants learned words significantly better if
IDS was used
Children who hear more child directed speech (CDS) have
Larger vocabularies
5 year olds understand sentences better in
Child directed speech (CDS)
By 4.5 months old infants recognise
Their own names
By 6 months old infants understand
“Mommy” and “daddy”
By 6-9 months old infants show understanding of
Some words for familiar objects
Children with repeated failures in recognising names were diagnosed with
ASD earlier than other children with ASD
Monolingual and bilingual children develop
Overall similarly
Most of children’s early vocabulary are words for
Solid, shape based categories with count noun syntax
If a shape bias is learned by learning words
We should be able to teach a shape bias through vocabulary training
Children trained on shape categories developed a
Precocious shape bias
Children trained on shape categories over
Generalised the shape bias to non solid substances
