Stages of Development Flashcards
Pre-verbal stage - vegetative
Sounds of discomfort or reflexive actions (0-4m)
Pre-verbal stage - cooing
Comfort sounds and vocal play using open-mouthed vowel sounds (4-7m)
Pre-verbal stage - Babbling
Repeated patterns of consonant & vowel sounds (6-12m)
Pre-verbal stage - Proto-words/scribble talk
Word like vocalisations, not matching actual words but used consistently for the same meaning (9-12m)
Proto-word example
Using ‘mmm’ to mean ‘give me that’ as well as an accompanying gesture.
Lexical/Grammatical development - Holophrastic/one-word
One word utterances (12-18m)
Lexical/Grammatical development - Two-word
Two word combinations (18-24m)
Lexical/Grammatical development - Telegraphic
3+ words combined (24-36m)
Lexical/Grammatical development - Post-telegraphic
More grammatically complex combinations (36+m)
Phonological development - Plosives
Created when the airflow is blocked for a brief time
Plosives voiced and unvoiced
V: b, d, g
UV: p, t, r
Phonological development - Fricatives
Created when airflow is only partially blocked & air moves through mouth in steady stream
Fricatives voiced and unvoiced
V: v, ð (THy), Z, ʒ (deluSion)
UV: f, θ (THigh), s, ʃ (SHip)
Phonological development - Affricates
When you put plosives and fricatives together
Affricates voiced and unvoiced
V: dʒ (Judge)
UV: ʈʃ (CHurch)
Phonological Acquisition sequence - 2 y/o
Phoneme - p, b, m, d, n, w, t
Phonological Acquisition sequence - 2.5 y/o
k, g, h, ŋ (kiNG)
Phonological Acquisition sequence - 3 y/o
f, s, j, l
Phonological Acquisition sequence - 3.5 y/o
ʈʃ (CHurch), dʒ (Germ), V, Z, ʃ (fiSH), r
Phonological Acquisition sequence - 4 y/o
ð (smooTH), ʒ (beiGe)
LOOK IN BOOK
HIGH LEVEL AND EXTRA NOTES
Early phonological errors and example - Deletion
Omitting the final consonant in words. Eg. do(g)
Early phonological errors and example - Substitution
Substituting one sound for another. Eg. ‘pip’ for ‘ship’
Early phonological errors and example - Addition
Adding an extra vowel sound to the ends of words, creating a CVCV pattern. Eg. doggie
Early phonological errors and example - Assimilation
Changing one consonant/vowel for another Eg. ‘gog’ for ‘dog’
Early phonological errors and example - reduplication
Repeating a whole syllable
Eg. dada and mama
Early phonological errors and example - Consonant cluster reductions
CCR difficult to articulate so children reduce them to units.
Eg. ‘pider’ for ‘spider’
Early phonological errors and example - deletion of unstressed syllables
Omitting opening syllable in polysyllabic words
Eg. ‘nana’ for ‘banana’
Theory: Explain ‘fis’ phenomenon
Dialogue based on research conducted in ‘60’s by Jean Berko & Roger Brown.
- Children may not be able to say words but can perceive them correctly mentally
- Disapproves Skinners imitation theory
Theory - Alan Cruttenden (1974)
Found children below 7 were less skilled at interpretation of intonation then adults
Language acquisition device (LAD)
Human brain inbuilt capacity to acquire language
Universal Grammar
Explanation that all languages share the principles of grammar despite surface differences in lexis/phonology
Phonemic expansion
Variety of sounds produced increases
Phonemic contraction
Variety of sounds reduced to the sounds of the main language used
