Q

Define the Behavioural Abstraction Hypothesis?

A

Only understand only surface- level of behaviour and form behavioural rules


‘BAH’ posits that chimpanzees:
- make predictions about future behaviours that follow from past behaviours, and 

- adjust their own behaviour accordingly

Q

What did Call and Tomasello 2008 find

A

That chimps imitate novel action when he seemed to do it intentionally but not when this was due to physical constraint.
Chimps understand others goals and intention

19
Q

Who studied Altruistic helping?

A

Wamelken and Tomasello 2006

20
Q

Define altruistic

A

Helping someone else without any reward, motivated to help as you as you don’t benefit from it

21
Q

Who did Wamelken and Tomasello 2006 study?

A

18m infants

36-54 months

22
Q

What did Wamelken and Tomasello’s 2006 procedure involve

A

Out-of-reach 

Access thwarted by physical 
object 

Achieving wrong result 

Using wrong means

23
Q

What did Wamelken and Tomasello’s 2006 find?

A

Children and chimps both willing to help without reward or praise 

Chimps helped more in reaching tasks than other tasks (salient cue?)

24
Q

Who studied if chimps could follow gaze when a target couldn’t be seen

A

Povinelli & Eddy (1996)

25
Q

Did Povinelli & Eddy (1996) produce positive or negative evidence for chimps following gaze

A

Negative

26
Q

What can chimps perceive

A

Finest subtleties of eye movements and gaze directions

27
Q

Do chimps learn rules about visual perception

A

YESo

BUT:
 these rules do not necessarily incorporate the notion that seeing is “about” something

28
Q

In what year was it concluded that chimps cannot reason about seeing

A

1996

29
Q

What are the 3 explanations about chimp perception

A

General delay in psychological development in chimpanzees.

Chimpanzees may possess a different (but nonetheless mentalistic) theory of attention

Subjective understanding of visual perception may be unique to humans

30
Q

Who presented positive evidence of chimps following gaze?

A

Kaminski et al. 2004

31
Q

What did Kaminski et al. 2004 find

A

That chimps begged more when they were being watched, suggesting that they can tell where someone else is looking
Chimps are sensitive to both body and face orientation but not eyes

32
Q

In the lab, have positive or negative results been found for co-operative communication with humans?

A

Negative

33
Q

What did Hare, Call and Tomasello’s 2001 Competitive paradigm find?

A

That chimps can reason about others knowledge on the basis of what the others have / have not seen.

34
Q

What are the two interpretations of Hare Call and Tomasello’s 2001 work?

A

Behavioural Abstraction

Mental-State Attribution

35
Q

What is the behavioural abstraction interpretation of Hare Call and Tomasello 2001

A

“He was present and facing the food when it was placed where it is now therefore he is likely to go after it” 

“He was not present when the food was placed where it is now therefore he is less likely to go after it”

36
Q

What is the mental-state attribution of Hare Call and Tomasello 2001

A

“He was present and facing the food when it was placed where it is now so he saw the food placed and currently knows where it is therefore he is likely to go after it”

“He was not present when the food was placed where it is now so he didn’t see it, therefore he doesn’t know.. therefore he is less likely to go after it”

37
Q

In what ways do perceptions differ?

A

Need to distinguish between own and others views, difference between seeing and knowing.

38
Q

What did Hare et al. 2006 find about chimp ToM with regards to perception

A

Found that chimps show visual and auditory perspective taking.

39
Q

What did Melis Call and Tomasello 2006 find regarding auditory perspective taking?

A

In the presence of a human competitor, chimps preferred to reach through a silent rather than noisy tunnel.
Suggests they are sensitive to what others can hear 

Are able to manipulate the auditory perception of a competitor 


40
Q

When Call and Tomasello 1999 conducted an FB task with chimps, how many passed?

A

None

41
Q

What is a key difference between Call and Tomasello 1999s FB test and Marticornea et al. 2011

A

Marticornea et al. 2011 conducted the test on monkeys in the wild

42
Q

What did Marticornea et al.’s FB task find

A

Monkeys represent others knowledge but not their beliefs - can represent whether the actor is knowledgable or ignorant but cant represent others beliefs.

43
Q

What method did Krupenye et al. 2016 use to study false beliefs

A

Eye tracking in anticipatory faze paradigm based on Southgate 2007
