Introduction to Sign Language and Deaf Community Awareness
What this domain tests
The exam checks whether you can explain sign language as a natural visual-gestural language, distinguish deaf and Deaf, and describe the barriers Deaf people face. Expect definition questions, myth-busting, and short applied scenarios.
Core rules and concepts
- Sign languages are complete languages with their own vocabulary and grammar; they are not pantomime, gesture systems, or signed English.
- Indian Sign Language (ISL) is used across India but is not universal and shows regional variation. ASL, BSL and ISL are different languages.
- Signs are built from parameters: handshape, location, movement, palm orientation, and non-manual features. Changing one parameter can change meaning.
- deaf (audiological) and Deaf (cultural identity) are different. Use the person's preferred term; many prefer Deaf or deaf, not hearing-impaired.
- Lipreading is partial and tiring; writing notes is not full access. Access means interpreters, captions, visual alerts, and clear sightlines.
Worked example
A student says, 'ISL is just English words in the air.' How do you correct this? Reasoning: point to grammar, not just vocabulary. English uses articles and copulas; ISL often uses topic-comment order and non-manual marking. Example: English 'I have finished my homework' may be glossed HOME WORK ME FINISH with a head nod and appropriate aspect. The order and the absence of 'have' show it is not English. Then note that fingerspelling English names does not make ISL English.
Traps that cost marks
- Calling sign language universal or 'international sign'.
- Describing signs as 'charades' or 'hand signals'.
- Saying Deaf people 'suffer from deafness' or 'cannot communicate'.
- Assuming lipreading alone gives full access.
