Q

phonological development

A

infants are born with ability to discriminate between sounds of any language (universal listeners) - this ability declines during first year of life

0-2 months: non speech noises

2-4 months: cooing, more diverse vowels, beginning of syllables

4-8 months: more obvious syllables

6-12 months: canonical babbling

12-15 months: first words

15-24 months: complex babbling

Q

common errors when language is developing

A

Q

initial omission of morphemes

A

toddlers initially omit many morphemes (e.g. I…..big, I…..eating)

rate of omission gradually decreases up to 3 years. by 4 years morpheme omission is a sign of language difficulties

Q

morphological overgeneralisation

A

child treats irregular forms of words as if they were irregular
e.g.

Q

what is syntax

A

rules which allow the organisation of words into large structures

17
Q

syntax comprehension 12-18 months and 18-24 months

A

12-18:
- understands simple sentences with familiar objects and actions

18-24:
- understands simple sentences with familiar objects and actions in more complex contexts with less adult scaffolding

18
Q

syntactic production: what are holophrases

A

rote learned chunks, such as ‘whaddat’ or ‘allgone’ often learned alongside first words

19
Q

syntactic production - 24 months and 30 months

A

by 24 months, majority of children producing at least two word combinations, that have been described as telegraphic speech because nonessential elements are missing

by 30 months, most children are starting to use a range of basic sentence types

20
Q

by 4-5 years, all children are proficient in…

A

comprehension of a range of abstract semantic concepts

fluency with a range of sentence frames

using range of connectives appropriately

21
Q
A

language comprehension from two years is a very good predictor of later language development, and developmental issues more generally

if a child is not understanding simple phrases by 24 months he or she should be referred for assessment by a speech and language therapist

22
Q

what are pragmatics

A

how language is used and interpreted in a contextually appropriate manner for the purpose of social interaction

contextually appropriate: adapting to what your listener knows, using the appropriate language register

for the purpose of social interaction: conversation, gossip, jokes, relaying past events, etc

23
Q

pragmatic development - what are the skills that develop?

A

using the right expression to refer to something

understanding inferences

being able to talk in different registers (e.g. talking to a friend vs in a job interview

24
Q

what are the two factors that influence language development

A

quantity of language input to a child

quality of language input to a child

25
Q

the role of TV and social interaction in language

A

children between 2 1/2 and 3 years can learn words from TV if someone is sitting beside them describing it

26
Q

how is background TV linked to language in preschoolers?

A

negatively related to language

27
Q

beneficial contexts for oral language

A

socio-dramatic play

interactive book reading (children need to answer with whole sentences)

28
Q

what are the cognitive systems in the brain that are involved in learning language

A

auditory and visual system

memory system

attention system

processing system

inferencing system
