Phonology In CLA Flashcards
Phonological Simplifications
Deletion, assimilation, consonant clutter reduction, addition, substitution
Deletion
- A child drops a consonant from a word when it is surrounded on one or both sides by vowels.
- This usually (but not always) occurs at the end of words. For example, a child may say /dɒ/ instead of /dɒg/ - they have deleted the end-position voiced velar plosive (/g/) from the word.
Assimilation
- This is when a sound later on in the word has an influence on other sounds in the word.
- For example, the /b/ sound in ‘rabbit’ might assimilate to the front-position of the word to form ‘babbit’.
Consonant cluster reduction
This is when a child reduces a set of consonants that are all together. For example, in the word ‘spider’, they may reduce the ‘sp’ digraph (two letters) by removing the ‘s’ from the cluster.
Addition
This is when a child adds a spurious consonant or vowel to a word. For example, adding the ‘y’ sound onto words like ‘dog’ to form the diminutive ‘doggy’.
Substitution
This is when a child changes one sound for another (usually one easier to say). For example, children often substitute the voiced palatal approximant (/j/) for the voiced alveolar lateral approximant (/l/) in the word ‘yellow’.
The ‘fis-fish’ phenomenon
The ‘fis-fish’ phenomenon proved that children can notice mistakes, but not recognise that they are making these mistakes.
- Conducted by Berko and Brown, the ‘fis-fish’ phenomenon happened when a child was talking to their caregiver about what they called their plastic ‘fis’.
- When the caregiver repeated this to them, they were able to recognise that the caregiver had said ‘fis’ and not ‘fish’, but could not then pronounce ‘fish’. This shows that comprehension precedes competency
17-week-old-foetus
- From around seventeen weeks, a foetus can hear sounds in utero. This is often shown when a child reacts more when they hear a certain voice or when they hear a certain piece of music.
- This is often shown again after birth.
Mehler
In 1988, Mehler found that French babies had a stronger reaction to French sounds at four days old than they did to English, Spanish or Italian.
* This proved that babies become accustomed to their native language before birth.
Pre-lingual stage 1 and 2
Stage 1: Biological noises – 0-2 months
Stage 2: Cooing and laughing – 2-5 months
We begin to see a control of vocal chords, but the sounds are meaningless, like ‘coo’,’ hoo’ and ‘ga’.
Pre-lingual stage 3
Stage 3: Vocal play – 5-8 months
The child begins to experiment with different vowel and consonant sounds.
* The child begins to play with pitch.
* There is no meaning behind these noises – they are playing.
* Parents may respond very positively to certain sounds and as a result, the child may produce these again and again.
Pre-lingual stage 4
Babbling – 6-12 months
There are two types of babbling – reduplicated and variegated.
- Reduplicated babbling happens when the sound is repeated. For example, ‘mamama’.
- Variegated babbling happens when the sound is differed, like ‘dabama’.
Phonemic expansion and contraction
To start with, a child will try as many new sounds as they can – this is called phonemic expansion. At roughly 9/10 months, the child narrows their range to those found in their native language. This is called phonemic contraction. At this point, a parent can recognise a child of the same nationality. A child gains more control over their body and face at this point, and so paralinguistic features develop (gesturing and facial expressions). A child also develops intonation as of real speech. This includes rising intonation at the end of the interrogative mood
Pre-lingual stage 5 and 6
Stage 5: Melodic utterances – 9-18 months
- A child lets out utterances containing rhythm.
- Tone is developed.
Stage 6: protowords – around a year
A child starts to use protowords. These are utterances which resemble words and are word-like ‘dap’ for a phone. These protowords would not make sense outside of the context of primary caregivers.
Phonology - Consonant Acquisition
In the 1980s, Pamela Grunwell’s research examined rates of acquisition of consonant sounds. Her research details that generally, children will learn these phonemes at certain ages
