The first year Flashcards
what is phonemic expansion
inc the definition of phoneme
during babbling, the number of different phonemes produced increases
phoneme: smallest element of a sound which can impact the meaning eg ban and Dan
what is phonemic contraction and when does it happen
9-10 months , the number of phonemes produced reduced to those found in the native language
name 6 types of phonemic simplification
- deletion
-substitution
-assimilation
-consonant cluster reduction
-addition
-reduplication
what is deletion
-unstressed syllables
-final consonants may be dropped
define substitution with an eg
easier sounds are substituted for harder ones
- ‘t’ becomes ‘d’ ‘r’ becomes ‘w’
assimilation
- a process by which substitution occurs but the sound changes because of other sounds around it eg doggy becomes goggy
consonant cluster reduction
-groups of two or more consonants are reduced to smaller u it’s eg frog becomes fog
addition
adding an extra vowel to create a CVCV structure eg dog becomes doggy
reduplication
repetition of particular sounds and structures eg ‘choo choo’ ‘weewee’
intonation
as a child grows older, a wider range of meanings is expressed through intonation
- two word class MY car and my car
-although produced understanding the meaning still develops into teenage years
lexical development
a child’s acquisition of words
semantic development
a child’s acquisition of the meanings associated with those words
describe the rate of acquisition up to 7 years old
end of first year: child begins to speak
18 months : vocabulary of about 50 words
2 years : vocabulary of about 200 words
5 years : 2000
7 years : 4000
what has research shown about language acquired by children and what does it tend to be
-predicable patterns in the words/ word classes
-entities
-properties
-actions
-personal- social
name the 3 theories of overextension
categorical overextension :
