Communication -- Review
  • Communication any way in which one organism
    conveys information to another. Language is
    (often) a form of communication, not all
    communication is language.
  • All animals have ways of communicating. Do any
    non-human animals have language as we have
    defined it? (lexicon, rules, etc.)

7
Properties of language (for comparison with other
species)
  • Knowledge
  • Lexicon (arbitrariness).
  • Rules (creativity).
  • Use Stimulus-free.
  • Acquisition Little or no instruction.

8
Animal Comm (FR, 21-25)
  • Talking birds.
  • Spiders.
  • Fiddler crabs.
  • Bird calls.
  • Bird songs.
  • Honeybees.

  • 2. Nim Chimpsky (New York).
  • C. Lexigrams (Yerkish -- tape Chimp talk)
  • 1. Austin.

11
Bonobo (pygmy) chimps
  • Lexigrams
  • 1. Kanzi.
  • 2. Panbanisha.

12
Chimpanzees (1)
  • Knowledge Lexicon
  • Washoe -- 85 ASL signs (many arbitrary).
  • Other signing chimps -- same or more.

13
Chimpanzees (2)
  • Knowledge -- Rules (creativity) Chimp syntax
    -- Nim Chimpsky (FR, p. 354)
  • GIVE ORANGE ME GIVE EAT ORANGE ME EAT ORANGE GIVE
    ME EAT ORANGE GIVE ME YOU.
  • Unlike childs telegraphic speech in that longer
    utterances dont show combinations of semantic
    relations from earlier stages.

14
Chimpanzees (3)
  • Claimed knowledge -- Rules for combining signs
    (creativity)
  • Washoe WATER BIRD duck
  • Koko FINGER BRACELET finger ring
  • Course Reader, p. 93 -- Panbanisha Fight. Mad.
    Austin. (in various combinations)

15
Created forms in chimps
  • Water. Bird.
  • Waterbird.

16
Chimpanzees (3)
  • Stimulus-freedom.
  • Only 12 of Nim Chimpskys sign productions were
    spontaneous.
  • 40 were repetitions of trainers productions.

17
Chimpanzees (4)
  • No instruction.
  • All but Kanzi and Panbanisha required heavy
    instruction (careful arrangement of signs,
    etc.)
  • Kanzi and Panbanisha Apparently spontaneous
    acquisition.

18
Chimps (5) Concl
  • Lexicon -- maybe.
  • Rules -- very unlikely.
  • Stimulus-freedom -- limited.
  • Instructionless acquisition --
  • common chimps no.
  • bonobo chimps probably.
