As we saw yesterday, there are many different sign languages
which aid communication in deaf communities. But should this form of
communication be labelled as ‘real’ language?
Jean Aitchison (1998) recorded that there are ten
characteristics which are essential for human languages. These are arbitrariness, semanticity, cultural
transmission, use of the vocal-auditory channel, spontaneous usage, turn
taking, duality, displacement, structure dependence and creativity. In
order to judge the similarity between sign and spoken languages we need to
discuss whether sign language shows these features.
1)
Arbitrariness means that there are no
connections between words and the object that it describes. An example of this
is that the word chair does not in any way reflect the shape of a chair. Many
signs do show arbitrariness, for example the ASL for keep (http://www.handspeak.com/word/index.php?dict=ka&signID=1188).
However, some signs do relate very closely to their meaning and are very
iconic. Such as in ASL, the action for ‘cat’ is using fingers to imitate their
whiskers on one cheek. This hints that may be not all signs are arbitrary. But,
in English there are also exceptions to this rule since onomatopoeias, like ‘meow’,
show the sound of certain actions.
2)
Semanticity is the use of symbols to refer to objects
or actions. All sign languages show this because they contain a variety of
linguistic components, including verbs and nouns. Many sign languages contain
these components in very similar way to spoken languages and must refer to the
actions and objects as they are understood by other users.
3)
Cultural transmission is the ability for parents
to teach their children the language. Deaf children learn sign language in
similar stages as hearing children would learn spoken language. Especially if
the parents use sign language, the child will pick up the language within the
first 6 years. If the children have learning disorders, this will obviously
take longer unless they learn a more suited sign language like Makaton.
4)
Obviously, sign language does not use the
vocal-auditory channel. However, in certain sign languages like Signed English people
may speak at the same time as they sign.
5)
Just like any other language, sign language has
spontaneous usage because people are able to use the language freely.
6)
Turn taking is a major characteristic in any
language because it is the only way in which we can communicate effectively, so
that we can gain information and contact. Sign language uses turn taking to
form a conversation.
7)
Duality is the idea that language has two
different layers; the constituents of language such as letters or sounds and
the words that they form when put together. This is shown in finger spelling/
manually coded sign language because they use the alphabet to form words. This
is also shown when forming proper nouns, for in the majority of sign languages
you have to sign each letter of the name using the alphabet.
8)
Displacement is the ability to refer to things
that are not physically present. Sign language users have this ability as they
can use their signs to discuss anything that they want to.
9)
Structure dependence is a more complicated idea
people are able to recognise clauses and that certain words are related to each
other. This is harder to find in sign languages because they tend to be simpler,
however Signed English must show this characteristic as it relates closely to
the English language.
10)
Creativity shows that humans can discuss
anything that they like – even if it is absurd. It also shows that there are a
number of different responses to stimuli. For example, in an art gallery
someone may evaluate the art my saying ‘it’s lovely’ others may say ‘it’s too
bright’ where as someone else may say ‘I’m too hungry to look at art’. This
ability to communicate any thought is also shown in sign languages as there
are a vast variety of signs for every occasion.
As we have seen, Sign language shows a number of
characteristics shown throughout spoken languages and therefore I think it is
right that they are classed as natural languages. This was recently reflected
by an internet petition given by the Whitehouse. In December 2012 the minimum
signature requirement of 250,000 was met. The conclusions of this were that the
US parliament recognised ASL as a ‘foreign language’ and soon ASL should be
announced a ‘natural language’. Hopefully, this trend will shortly follow in
the United Kindgom. This shall boost awareness across the UK and hopefully help
users and the deaf communities. As quoted by G.Yule:
There is a very old joke among the deaf which begins with
the question ‘What is the greatest problem facing deaf people?’ Perhaps
increased knowledge and appreciation for the language among the world at large
will bring about a change in the old response to that question. The traditional
answer was ‘Hearing people’
