1. Design features of language LING 200 Winter 2009 Jan. 7

2. Plan for today Questions about language Questions about language Hockett’s proposed design features Hockett’s proposed design features Properties of some animal communication systems Properties of some animal communication systems

3. The big question(s) Is language unique to humans? Is language unique to humans? Is it fundamentally different from animal communication? Is it fundamentally different from animal communication? (What is language anyway?) (What is language anyway?)

4. Getting at the big question Charles Hockett (1960) “The Origin of Speech.” Scientific American 203: 88-96. Charles Hockett (1960) “The Origin of Speech.” Scientific American 203: 88-96. Smaller questions Smaller questions What are properties of human language?What are properties of human language? Which are shared by other communication systems?Which are shared by other communication systems? Caveat Caveat In Hockett’s day, not much known about ASLIn Hockett’s day, not much known about ASL

5. Hockett’s proposal Design features Design features characterize language, distinguish it from other communication systems System must have all 9 features to be language

6. 9 features Mode of communication Mode of communication Semanticity Semanticity Pragmatic function Pragmatic function Interchangeability Interchangeability Cultural transmission Cultural transmission Arbitrariness Arbitrariness Discreteness Discreteness Displacement Displacement Productivity Productivity Common to all(?) communication systems Not found in all communication systems

7. Interchangeability = A user can both transmit and receive messages Not all communication display this flexibility silkworm moths: only females secrete chemicals whistling moths: males make territorial sounds

8. Cultural transmission Nature (innate) (vs. nurture-- learned) Nature (innate) (vs. nurture-- learned) = At least some aspect of a communication system is learned from other users A Cambodian child with an American parent will learn English, not Khmer Animal communication systems vary Fireflies and cowbirds: entirely innate Fireflies and cowbirds: entirely innate Finches: can learn to make some calls if raised in isolation; but don’t learn full system Finches: can learn to make some calls if raised in isolation; but don’t learn full system

9. Arbitrariness (vs. iconic) (vs. iconic) Does the form of a sign/call/signal resemble what it refers to? Does the form of a sign/call/signal resemble what it refers to? Sign languages may seem relatively iconic… Sign languages may seem relatively iconic… KNOW BLACK CANADA

Productivity Unlimited potential to express novel ideas Unlimited potential to express novel ideas Elements of system are fixed or infinite?Elements of system are fixed or infinite? ““Intonational phenomena in Sahaptin identified to date can be described exclusively with nuclear pitch accents.” Bees Vertical sugar water experiment

14. Chimp (and other primate) studies 20 th century hypothesis: Maybe chimps (and other primates) don’t use human language because of lack of opportunity to learn it. 20 th century hypothesis: Maybe chimps (and other primates) don’t use human language because of lack of opportunity to learn it. Chimp vocal tracts not suited to speech, but sign language okay Chimp vocal tracts not suited to speech, but sign language okay

15. Chimps’ accomplishments Can learn to associate referents with arbitrary signs Can learn to associate referents with arbitrary signs Can learn to use signs spontaneously Can learn to use signs spontaneously Can learn to use signs creatively Can learn to use signs creatively Washoe (at CWU): 'water bird' (for swan)Washoe (at CWU): 'water bird' (for swan) Can invent totally new signs Can invent totally new signs Washoe: a new sign for 'bibs'Washoe: a new sign for 'bibs' Can come up with creative solutions to problems Can come up with creative solutions to problems Kanzi: When friend Austin the chimp was moved out of compound, Kanzi got lonely, typed 'Austin TV' to request videotape of Austin.Kanzi: When friend Austin the chimp was moved out of compound, Kanzi got lonely, typed 'Austin TV' to request videotape of Austin.

Chimps’ main limitation Syntax Syntax length: 2-3 sign utteranceslength: 2-3 sign utterances inconsistent word orderinconsistent word order See also http://www.gorilla.org/world/talk_aol.html See also http://www.gorilla.org/world/talk_aol.html Noam Chomsky (“I told you so”) Noam Chomsky (“I told you so”) It is hardly likely that some species has this capacity but has never thought to use it until instructed by humans…the evidence suggests that the most rudimentary features of human language are far beyond the capacity of otherwise intelligent apes, just as the capacity to fly or the homing instinct of pigeons lie beyond the capacity of humans.It is hardly likely that some species has this capacity but has never thought to use it until instructed by humans…the evidence suggests that the most rudimentary features of human language are far beyond the capacity of otherwise intelligent apes, just as the capacity to fly or the homing instinct of pigeons lie beyond the capacity of humans.

17. Summary and preview Human language seems to be qualitatively different from animal communication systems Human language seems to be qualitatively different from animal communication systems Human vocal tract even seems designed for speech Human vocal tract even seems designed for speech
