DESCRIPTION
This introduction to ideas about sign languages was prepared for Stanford University's Linguistics 1 course in November 2008. It emphasizes the 4 myths, shows some authentic ASL vlogs and websites that use ASL as one of the modes of communication. (Links have not been verified again.)TRANSCRIPT

Goals for Today
• Let’s share assumptions and questions about sign language
• Let’s correct some misunderstandings and decide how to reconcile some incompatible ideas
• Let’s agree on how to decide whether sign language fits in the scheme of human language behavior
• Let’s learn a few fun facts about signing

My contact with deafness
• Hard of Hearing mother • Toddler friend also “Hard of Hearing” • Junior High School friend had deaf
grandparents – We spelled; I learned a dozen signs
• Grad school entry (in linguistics) coincided with Bellugi’s first NIH grant

Your experiences with Deafness? Signing?
• School? • Scouts? • Sesame Street? • Other TV? Movies?
• Informal contact? • Formal instruction? • Language Files
readings?
This is where you get to ask stupid questions -- but, there are no stupid questions -- and reveal your assumptions and preconceptions

Some of the student questions • Genetics of deafness? • Differences between
ASL and other sign languages
• Expressive capacity? • How does ASL create
new words • Is ASL grammar
equivalent to English grammar
• When did signing start? • How does sign express
ideas like “sarcasm”? • Shouldn’t there be one
sign language – universal?
• Regional differences • “Music” equivalent?

4 Myths - 2x2
• Signing is Pantomime • Signing is Universal
• Signing is a coded form of speech • Signing is fingerspelling

Myth! Signing is Pantomime
• Is pantomime conventional? standardized? – Or can it change from one person to another?
From one occasion to another? – How about signing?
• Does pantomime fit the temporal requirements or habits of a human language?
• How culturally bound is pantomime? How about signing?
• Does pantomime imply “concrete” or “simple”? How about signing?

Myth! Signing is Universal
• If signing were a universal language, then – You would understand what we’ve seen on these
vlogs and websites without transcripts or interpretation
– You would not need any help understanding what any deaf person signs
– People from around the world would be able to communicate with each other successfully and effortlessly in gesture
– There would not be many sign languages, nor regional variation within each sign language
![Page 11: Sign Languages for Linguistics 1 (Stanford)](https://reader034.vdocuments.mx/reader034/viewer/2022052321/5484a1a9b479590a0d8b4c47/html5/thumbnails/11.jpg)
12 November 2008 Linguistics 1: Frishberg 11
Myth! Signing is a coded form of speech
• If signs are coded speech, then there is a 1:1 relationship between signs and spoken language – At what level would this coding happen?
• Sounds? Cf. Cued speech • Words? Parts of words? Cf. SEE, etc. • Spelling? (see next slide)

12 November 2008 Linguistics 1: Frishberg 12
Myth! Signing is fingerspelling Fingerspelling is a method of representing (English)
words using a series of manual gestures that correspond to the alphabet
• No difference between capital and lowercase, limited use of punctuation – i.e., it’s not writing
• One-handed vs. two-handed spelling – Quick aside on history of ASL and BSL, Rochester Method
• How does it function in the stream of signs?

12 November 2008 Linguistics 1: Frishberg 13
Signing is
• A mode of producing and perceiving specific primary human languages – ASL ≠ BSL; ASL ≠ LSF – Different sign languages are not mutually
intelligible to native signers – Not transparent to non-signers, but possible more
obviously iconic than (most) spoken languages • Capable of all expression available to other
modes of human language – Meets the duality of patterning criterion for human
languages

One- & Two-handed signs
Teuber, et al. (1980) computer tally of 1628 non-compounds
1-handed signs 38% N = 585
2-handed signs 62% N = 1230
Drawn from Stokoe, Casterline & Croneberg’s Dictionary of American Sign Language (1965).
Not based on usage frequency, but on dictionary entries.
