CLA Research Task
1) CLA developmental phases in correct order: Cooing, Babbling, Holophrastic, Two-word, Telegraphic, Post-Telegraphic.
2) A - Nativist -> N. Chomsky
B - Cognitive -> J. Piaget
C - Behaviourist -> B.F. Skinner
D - Interactional -> J. Bruner
E - Critical Period -> E. Lenneberg
3) This process is 'overextension' by analogy. The child sees similar shapes to the orange and uses the term by overextension to include the orange in the term.
4) This is called 'underextension'. This is because the child does not know the word 'shoes' is a hypernym and can be applied to other shoes. Cannot relate the term to a similar item.
5) This process is called 'overgeneralisation', when the child applies the general rule to an irregular verb. This term supports Chomsky's LAD theory.
6) Telegraphic stage - child has used subject verb but has missed out the copular verb 'is' and the preposition 'to'.
7) The child is using the first person object pronoun 'me' instead of the first person subject pronoun 'I'.
8) Substitution - child is replacing the 'ch' for a simpler sound 't'. But could also be seen as consonant cluster reduction as the child might have found it difficult to pronounce the 'ch' sound therefore it is reduced to a smaller unit.
9) Deletion - leaving out last consonant, child cannot recognise that they are not pronouncing.
10) Deletion of unstressed syllables - removal of 'ba', difficult to pronounce polysyllabic lexis.
11) Instrumental - expresses needs and wants e.g. 'want juice'.
Regulatory - to give commands 'lift me up'.
Interactional - to create interactions 'bye bye'.
Personal - to express thoughts, likes, dislikes and opinions e.g. 'I don't like fruit'
Imaginative - to create imaginary words or thoughts
Heuristic - to seek information 'what are you doing?'
Informative - to relay information - 'we had beef for dinner'
12) Jean Berko - using a made up animal tested application of the children of the '-s' plural rule and found nearly all applied it to a noun they've never heard before.
13) nouns - most common items around a child and easily understood as they can see them
14) equal so as if the child is a full participant, and teaching a child a Q&A style conversation.
15) CDS- stress of pronunciation on particular morphemes, interrogatives, imperatives, simplified grammar, tag q's & turn taking, paralinguistic.
16) A girl named the 'wild child'. She could not speak or communicate as she was locked in a room for 12 years and wasn't interacted with. Her case proves Lenneberg's 'critical period' and Bruner's 'interaction' theory.
17) Jim was born to deaf parents and placed in front of a tv in hope that he would pick up language from there but he didn't. Supports interaction theory (Bruner).
18) David Crystal, Jean Aitchison, Noam Chomsky.
19) Language Acquisition Device.
20) Determiners, Auxiliary Verbs.
