Q

By themselves, all gestures are meaningless to observers. Observers need what three things to allocate meaning?

  1. A learning history with the gesture that is influenced by
  2. Antecedents of gestural signals (behaviour, context)
  3. Consequences of gestural signals (receiver’s responses)

Q

What were some meanings determined by apparently satisfactory outcomes in chimpanzees?

A

Directed push has multiple ASOs, meaning is more diffuse
Hand fling has only one ASO, meaning is unambiguous within the group
When signaller ceases gestures, assumption is made that the receiver’s immediately previous response was viewed by the signaller as a satisfactory response

Q

Give an example of ontogenetic ritualisation

A
  1. Chimpanzee babies actively take food from mothers’ mouths
  2. Then they hold their hands very close to the mothers’ mouth
  3. Then they display a begging gesture from a distance
    The begging gesture becomes ritualised from a physical tool to catch any falling food, to a social tool to request food
17
Q

A ritualised gesture is an abbreviated version of what?

A

A mechanically effective act

18
Q

Finish the sentences about the key factors of biologically determined species repertoire…
1. Very large ____-_____ repertoire
2.Each individual displays a ______ of the full repertoire
3. High ____ in gesture meaning across groups
4. Evidence for ____ in ____ studies is attributable to overwhelming influence of predominantly ____ contexts

A
  1. species-typical
  2. subset
  3. concordance
  4. variability, captive, play (which renders a biased perception of inter-group variability)
19
Q

What are three factors of co-construction of meaning…
1. Some gestures appear to be largely _______ (wrist present)
2. Little support for _________ ritualisation, except that gestures are shaped through _______ interaction (tickling)
3. Some gestures seem neither ______ nor ________ from mechanically effective actions: individual pairs achieve a ________ understanding of a gesture’s meaning (grooming)

A
  1. innate
  2. ontogenetic, dyadic
    3.innate, ritualised, negotiated
20
Q

What are three factors of gestural theory of language origins…
1. Like speech, ape gestures are manifestly ________
2. Like speech, ape gestures reflect _____ ________ _________ dominance
3. Like humans, apes are even more ______-________ when they vocalise while gesturing

A
  1. intentional
  2. left cerebral hemisphere
  3. right-handed
21

A

6-7 million years ago

22
Q

A
  1. Thing(s)
  2. Sign(s)
  3. Concept(s)
24
Q

What kind of relationships are there between the poles in the semiotic triangle?

A

Arbitrary

25
Q

Where do concepts in the semiotic triangle take place?

A

In the mind

26
Q

What is a semantic lexicon?

A

A bunch of words about a concept stored in the mind

27
Q

What is meant by a dyadic gesture?

A

A gesture displayed from one individual to another individual

28
Q

What is meant by a triadic gesture?

A

Gesture and gaze directed to different things
E.g. gaze directed art human and gesture directed towards wanted food/desired outcome

29
Q

What is meant by a broadcast gesture?

A

A gesture not directed at something specific

30
Q

What is the key concept of The Shannon-Weaver Mathematical Model?

A

Information broadcasted/transmitted through channel; (noise source, e.g. voice travelling through air), speech decoded by receiver, recover original message in destination (receiver)

31
Q

Briefly describe an experiment into measuring persistence in chimpanzees

A

Banana outside case on one side, purina primate chow on other, all showed prefer for banana, gave banana, chow or half of banana
all that got banana stopped signalling completely after given banana
Persisted if given chow, persisted if only given half banana
