Spoken Theories Flashcards
17 week old foetus
- At around 17 weeks a foetus can hear sounds in the utero
- This is often shown when a child reacts more when they hear a certain voice or a certain piece of music
Mehler et al (1988)
- Found that four day old French babies increased their sucking rate on a dummy, showing interest or recognition, when they heard French as opposed to Italian or English
- Implies that babies become accustomed to their native language before birth
0-2 months - Biological noises
- Involves a lot of crying
- Child begins to gain control of their air stream
- This is UNIVERSAL - parents of all nationalities can recognise the different types of crying, as a result this is not really a ‘language’
2-5 months - Cooing and Laughing
- Child begins to try and control their vocal chords, sounds are meaningless, like ‘coo’, ‘hoo’ and ‘ga’
- Tongue control is evident when coos get strung together
5-8 months - Vocal Play
- Child begins to experiment with different vowel and consonant sounds
- 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
6-12 months - Babbling
- Babbling happens for a long time, permeating even into the holophrastic stage
- Consonants begin to get linked to vowels (still no meaning to sounds)
- Parents will react if ‘da’ or ‘ma’ is formed
- Child will try as many new sounds as they can - PHONEMIC EXPANSION
- At roughly 9/10 months, the child narrows their range to those found in their native language - PHONEMIC CONTRACTION
- At this point, a parent can recognise a child of the same nationality
Types of babbling
- Reduplicated - when sound is repeated, e.g. ‘mamama’
- Variegated - when sound is differed, e.g. ‘dabama’
9-18 - Melodic utterances
- Child lets out utterances containing rhythm
- Tone is developed
~1 year - Protowords
- Child starts of use protowords
- These are utterances which resemble words and are word-like, e.g. ‘dap’ for a phone
- These protowords would not make sense outside of the context of primary caregivers
Grunwell (1987)
Examined rates of acquisition of consonant sounds - children will generally learn these phonemes at these ages:
- 2 years: /p, b m, d, t, w, n/
- 2.6 years: /k, g, h/
- 3 years: /f, s, j, l/
- 3.6 years: /dʒ, v, z, r, tʃ, ʃ/
- 4 years: / θ, ʒ, ð/
Gervain (2012)
- babies at 2 and 3 days old had peaked brain activity with reduplicated syllables
- however this does not explain why so many of the first words contain variegated syllables
Crystal - ‘ma’ and ‘da’ syllables
- Argues that children recognise that their parents get very excited when they say ‘ma’ and ‘da’ syllable and as a result, this increases the frequency they say this
- But this does not constitute understanding - Crystal states that it will be many months before the child can link their production of ‘mama’ or ‘dada’ to the parental caregivers
Holophrastic stage (around 9-18 months)
- characterised by one-word sentences; HOLOPHRASES
- nouns make up ~50% of vocab is nouns, ~30% is modifiers and ~20% is negatives and questions
- in this stage children will primarily use language to contain things they want/need
Two-word stage (around 18-24 months)
- utterances of two words only
- other word classes start to emerge but nouns still dominate
- syntax is explored correctly
- inflections are not applied to verbs
Telegraphic Stage (around 24-30 months)
- utterances are abbreviated, like SMS or telegrams; misses out the grammatical structures or markings that are not essential for understanding
- wider range of word classes are acquired (particularly pronouns, followed by determiners and prepositions)
Post-telegraphic stage (around 3-5 years)
- period of time when a child’s language will include both content and grammatical words and more closely resemble adult speech
- this also includes having learned time features, contracted negatives and increasingly accurate inflections
Bellugi - Learning of negations
- Between being Holophrastic and Two word, the child starts to front negatives e.g. ‘no like that’
- Approaching the telegraphic stage, the child is starting to place negatives before the main verb e.g. ‘don’t like you’
- Past this, negation is almost always correct and errors tend to be virtuous
Brown - Acquisition of Grammatical Constructions
Brown proposes grammatical constructions are always learned in this order:
1. Present progressive e.g. I am walking
2. Prepositions e.g. by, on, at…
3. Simple plural e.g. he walks
4. Possessive e.g. Trudi’s boat
5. Uncontracted copula e.g. Stuart is acting
6. Articles e.g. the, a, an
7. Regular past tense e.g. I walked
8. 3rd person regular verbs e.g. Dave types
9. 3rd person irregular verbs e.g. Suz teaches
10. Auxiliary verbs e.g. ‘be’ - I am, he was, you are
11. Contracted copula e.g. Stuart’s acting
12. Contracted auxiliary e.g. I’m, you’re
Katamba - supporting Brown
argues that this order is the same regardless of parental input
Halliday - functions of language
Children will learn language so that they can achieve things.
- Instrumental (to show needs and desires)
- Regulatory (to get people to do something)
- Interactional (to interact with others and form relationships)
- Personal (explores feelings and identity)
- Heuristic (explore the world and environment)
- Imaginative (used to be imaginative)
- Representational (language used for facts)
Rescorla - Overextension
Categorical - child uses one word to describe everything in a category, HYPERNYM e.g. ‘dog’ to describe all breeds of dog
Analogical - child uses a word to describe something which is physically similar or serves a similar purpose e.g. ‘van’ for a car
Relational - when the word used has some form of relation to the incorrect words e.g. ‘car’ to represent a road
Skinner (Behaviourism)
Children learn language based on positive and negative reinforcement of ideas
Positive reinforcement: praise which encourages the child to repeat correct utterances
Negative reinforcement: behaviour which will deter a child from reusing an incorrect utterance; tone of voice and paralinguistic features will often assist this
