Unlike other " oral communication , " polarity language — be it American or otherwise — is a ocular language , and therefore , can take a prospicient prison term to passkey . Here are some other things you might not know about sign language .
1. Different countries have different sign languages.
Why should there be more than one sign language ? Does n’t that just elaborate things ? Those questions would make sense if sign linguistic process was a system forge and then handed over to the Deaf community as an assistive gimmick . But foretoken languages , like spoken languages , develop naturally out of groups of people interact with each other . We know this because we have observe it come about in material time . It ’s reckon that there are more than300 dissimilar types of mark nomenclature .
2. With time, improvised gestures can evolve into a full language.
In 1980 , the firstNicaraguan schoolhouse for the Deaf opened . educatee who had been previously isolated from other Deaf hoi polloi brought the gestures they used at home , and make a sort ofpidgin signwith each other . It go for communication , but it was n’t coherent or pattern - governed . The next generation who came into the school learned the pidgin signaling and ad lib started to regularize it , creating ruler for verb agreement and other consistent grammatical devices . Over time , it stabilized into a full - fledged linguistic scheme known as Idioma de Señas de Nicaragua ( ISM ) , orNicaraguan Sign Language .
3. Sign language does not represent spoken language.
Because sign languages modernise within Deaf communities , they can be independent of the surrounding spoken language . American Sign Language ( ASL ) is quite different from British Sign Language ( BSL ) , despite the fact that both body politic speak English .
That said , there is a lot of link between sign language and spoken language ( Deaf people read and write or speech-read in the wall lyric ) , and sign languages ruminate this . English can be interpret throughfingerspellingor artificial systems like Signed Exact English ( SEE ) orCued Speech . But these are code for speak or write language , not languages themselves .
4. Sign languages have their own grammar.
There arerules for well - formed sentencesin sign language . For example , sign voice communication uses the outer space in front of the signatory to show who did what to whom by point . However , some verb point to both the subject and aim of the verb , some point in time only to the physical object , and some do n’t point at all . Another rule is that a well - form question must havethe correct kind of eyebrow status . supercilium should be down for a who - what - where - when - why inquiry ( as seen in the video above ) , and up for a yes / no question . If you use the rules wrong , or inconsistently , you will have what is known as a " alien " accent .
5. Children acquire sign language in the same way they acquire spoken language
The stages of sign language acquisition are the same as those for spoken language . Babies protrude by " blither " with their bridge player . When they first start producing words , they interchange easier hired man shapes for more hard I , make for precious " baby pronunciations . " They start making conviction by stringing signs together and only later get ascendancy of all the grammatical rule . Most significantly , as seen in the above video , they learn through natural interaction with the people around them .
6. Brain damage affects sign language in the same way it affects spoken language.
When fluent signer have a stroke or brain injury , their ability to signmay suffer a similar type of aphasia , but they are still able to make onomatopoeic or non - sign gesture . They may be able to produce house , but not put them in the right well-formed conformation . They may be able to produce sentences , but with the signs take shape incorrectly , thus creating a unusual accent . They may be able to signalize quickly and easily , but without making any sensory faculty . We get it on from studying speaking people that " making sound " is quite different from " using language " because these function are affected differently by learning ability damage . The same is unfeigned for signers . Neurologically , make gesture is quite different from using planetary house language .
7. Sign language is a visual language.
This one is pretty obvious , but it ’s important to cite . Sign language is just like speak lyric in many manner , but it ’s also different . Sign can be very straight and formal , but it can also take full advantage of its optical nature forexpressiveor aesthetic effect ( as demonstrated in the video above ) . Which , when you think about it , does n’t make sign words all that different after all : For expressive purposes , we can take full advantage of spoken language ’s auditory nature . We can also take reward of facial expressions and gestures when we speak . Everything that would be in an artistic speak performance — the words , the ordination of clauses , the suspension , the breathing time uptake , the chanting and strain , the stressing or deemphasizing of sounds , the facial and outspoken emotion , the trunk posture and head teacher and bridge player motion — come through together in sign language . It reckon awesome not because it shows us what mansion language can do , but because it shows us what language does .
