BBC video – Dr. Robert Winston; How children acquire language.
Linguistic skills are one of the most important things to
learn in the human culture – it is a necessity for human life. We use words and
language to communicate, express ideas, thoughts and emotions, to show
experiences and much more. It is a proven fact that when a child learns a
language, it is significantly easier for them to learn compared to an adult
learning a second language – this is because a different part of the brain is
used. As stated in the documentary, ‘’clams have their shells and we have our
language’’ – this stresses the importance of language which is shown through
the need to learn it at such a young age.
In this clip, it shows 15 month old Zac as a young toddler
beginning to learn the basics of language. In the back of the throat, there is
a vocal tract known as the larynx which sticks up and is very high until around
the age of 2. The location of the larynx at Zac’s age means that it is
difficult for him to produce certain sounds – however, the position of the
larynx allows him to breathe and suckle at the same time. In order for Zac to
be able to produce a wider range of speech, his larynx will need to have
dropped by 3cm – in this way, the larynx becomes the voice box which thus
allows speech to be made. It has been proven that for a child to produce one
word it takes a total of 30 muscles in the face – the tighter the chords in the
throat, the higher the voice. Although the lowering of the voice box is
essential for the beginning of speech production, it does have its constraints
– in some cases it may lead to instances of choking.
Moira, a two and a half year old girl is much more advanced
compared to Zac in terms of linguistic and grammatical skills – at this age,
she is likely to learn 10 new words per day. It has been argued that children
around this age are like sponges, they tend to soak up all forms of language
through imitation – this supports Vygotsky’s theory or social interaction. The
documentary showed Moira coming into contact with an animal she had never seen
before – a fawn. Once her mother had said the word, Moira was able to imitate
it with no problem whatsoever. Moira also used overgeneralisation when
speaking: when asked what the plural of a mouse was, she said ‘2 mouses’ rather
than the correct utterance ‘2 mice’. It is clear that Moira had formed this
utterance alone as there was no possibility of her learning it through
imitation. This supports the idea that children get grammar correct virtually
all the time yet make mistakes when irregular verbs are not taught. In this
way, grammar is innate when it comes to learning language – all is understood
with the exception of irregular verbs. Moira is applying the logical rule of
making a word plural, yet fails to do so correctly due to the verb being
irregular.
Towards the end of the documentary, the concept of
self-awareness is explored. There is an abstract example of reflection – Julia,
who is 14 months old lacks self-awareness simply because she does not have the
cognitive ability to recognise herself. However, Moira who is over a year older
is aware of her identity which is shown through the use of the pronoun ‘I’ and
‘me’. In this way, Moira is aware that she is a different person to everyone
else and therefore is wary of her own needs. However, there are consequences of
self-awareness, it can lead to many children entering the tantrum stage, also
known as the ‘terrible two’s’. At this age, Moira has self-awareness to
recognise her needs and has the linguistic ability and language to express
these. Moira uses the personal pronouns in order to get her own way, also with
the use of declaratives such as ‘’I’m hungry’’.
To conclude, children’s brains and bodies adapt to ensure
that they are able to acquire language. This is evident through the positioning
of the larynx, the ability to learn language and their innate grammatical
skills. Most of what children learn is through imitation with the exception of
overgeneralisation – a mistake made as a result of children’s confusion with
irregular verbs.
