Intentionality in animals Flashcards
What are the problems with detecting consciousness?
1) No external sign so can’t be sure even for humans
How do I know you are not an android?
2) Definition unclear - “immediate subjective awareness” ?
3) Purpose unclear
What is consciousness for?
We’re not 100% sure BUT
- Complex movement perhaps - Actually slows us down!
- Problem solving - however “sleep on it” works better!
- Changing type of action - Possibly smoothes changeover
- In novel situations - can mentally try options
- Social behaviour prediction.
What is consciousness
awareness of the outside world and ourselves, including our own mental processes, thoughts, feelings, and perceptions
In order to know if animals have awareness, two questions were asked - what were they?
1) Do animals show behaviour which can be taken as evidence of intention, belief, deception etc.?
2) Are they aware of these states of mind in the way we are? (i.e. are they conscious?)
What is Intentionality?
the idea that animals think about things
What are the orders of intentionality?
Zero Order
1st - 6th Order
What is the zero order of intentionality and give an example
learning about stimuli
e.g. tube worm learns not to respond to safe touches, dogs learn to do tricks for rewards.
What is the 1st order of intentionality and give an example
beliefs about the real (or imagined) world
e.g. Dog knows food is in the cupboard (he might be wrong).
What is the 2nd Order of intentionality and give an example
beliefs about the mental state of others e.g. he knows that YOU know he won’t fall off.
What is the 3rd Order of intentionality and give an example
self awareness of that knowledge
e.g. he is aware that he wants you to decide that he won’t fall off.
What is the 4th Order of intentionality and give an example
self awareness of another’s knowledge about a third party.
e.g. he knows his mother thinks you know he won’t fall off.
What is the 5th order onwards of intentionality and give an example
add another step each time
e.g. I am aware that I want you to believe that Michael’s mother trusts that you know he won’t fall.
What is the 6th order of intentionality and give an example
people can manage these but have to write it down.
In most situations, how many orders of intentionality do we operate at?
we operate at about three orders of intentionality.
How do we decide what orders of intentionality animals show?
Using the “Theory of Mind”
What is the “Theory of Mind?”
“Theory of Mind” is the branch of study considering animals with at least 2nd order intentionality, aware of their own and other individuals’ state of knowledge.
Increasingly strong evidence of Theory of Mind include what :
1) Ability to hold abstract ideas
2) Self Awareness
3) Manipulation and deception
4) Knowledge attribution
How does the ability to hold abstract ideas provide evidence for the theory of mind and give an example of an experiment
You need this to hold ideas about the world independent of what you are seeing at the time.
Irene Pepperberg studied Alex
1) Trained to respond verbally, naming objects
2) Taught words for attributes of objects e.g. colour, shape, number present
3) Offered unfamiliar objects and asked colour, number, shape
Result: Gave the correct colour, number or shape without name for object
Conclusion: must have abstract idea of colour etc. to be able to transfer it to unknown objects.
What is the test for chimps to prove self-awareness?
Name the drawbacks
Classic test = “mirror test” or “mark test”
Put mark on chimp’s head when asleep, then when awake, offer mirror
Chimp will touch mark more often than they would if no mirror, and than if they didn’t recognise the reflection as themselves
Drawbacks :
BUT
Not all chimps show the behaviour
Behaviour doesn’t appear immediately
- initially respond socially
- learn over time to use mirror for self inspection
What is the real problem with the mirror test to prove self-awareness?
30 Given Mark Test:
“Self-recognisers” 50% passed
“Non self-recognisers” 11% passed
Very imperfect correlation between results and skill we think it tests!
How does manipulation and deception provide evidence for the theory of mind? Example!
If animals are aware of each others’ thoughts, they may use this knowledge to manipulate or deceive them.
Female groomed by subdominant, hides from dominant male.
Must have at least 2nd order intentionality to know the male’s mind holds information different from her own.
But beware of instrumental learning once again!
What is the triangulation method
method of testing theory of mind by comparing behaviour in learned situations with behaviour in novel situation. Transfer to novel situation avoids the possibility of learning as explanation
If just associative learning, then learn each situation separately, if not then interconnected!
With the triangulation method, what is the purpose of transferring to novel situations?
Transfer to novel situation avoids the possibility of learning as explanation
A triangulation test was done on Long tailed macaques - explain
Triangulation Test: Screen added for monkeys to hide behind
Training: Monkeys learned to avoid drinking when trainer facing cage as would spray them with hose.
If drank when his back is turned, no penalty.
Have they learned:
“trainer will stop me drinking if he sees me” (theory of mind response)
or:
“Don’t drink if trainer facing or I get wet”?
(Instrumental learning rule)
Results: No preference for screened site when experimenter facing.
Conclusion: no evidence of > 0 order intentionality
