1
Q

What is ecological validity? Why is it important to consider when discussing primate cognition in the lab?

A

possibility that experiments tap into real life problem solving skills; lab could suggest something when in actuality it is not true

Q

What is “transfer”?

A

apply learned concept or strategy to novel stimuli, require fewer “trials to criterion”;
“learning to learn”

Q

What is “first trial success”?

A

after training, full immediate transfer to novel task and/or stimuli w/o additional reinforcement

trained to novel set: success then transfer as good as can get

Q

What lab studies have studied how primates represent space and what have they shown about their ability?

A

primates can learn to navigate a virtual space i.e. some chimps can use toy object placed in 3D model to find real object in actual room, show efficient search abilities

Q

Why would how primates represent space important for their survival?

A

efficient to never to go twice to the same hiding place in wild, chimp searches efficiently for food, etc.

Q

Why is object permanence important for survival?

Q

What are invisible displacements?

A

know that something is hidden, can infer that the object is gone even though did not see it go somewhere

i.e. Exp. hides apple at X, pear at Y, distracted, then see Exp eating apple => only look for Y

Q

What is the trap tube test?

A
  1. clear tube with good in it, potential tools (in bundle, in pieces) to push food out in other room
20
Q

How did Cebus respond to the trap tube test?

A

can hit upon solution after trying many alternatives, when trap mid tube, 1 Cebus learned to avoid, push food out other way but avoided even when trap rotated to top

21
Q

How did apes respond to trap tube test?

A

apes tend to modify, try only appropriate tool

note: even chimps require many rials to learn, some persists in Cebus-like responses

22
Q

What are the only three primates that interact in free play with objects?

A

Cebus, Papio, and Apes

23
Q

How do chimps with extensive human interaction interact with nesting cups?

A

can spontaneously subassemble whole set

24
Q

How do cebus and chimps do with nesting cups?

A

can put 1 or 2 small into large “pot method”

25
Q

What is “insight” in relation to primates and completion of tasks?

A

when solution to task appears suddenly

26
Q

How did Kohler’s Chimp Sulta display insight?

A
  • banana suspended over cage, suddenly got up and stacked boxes to reach it
  • treat outside cage; later discovered 2 short sticks could be joined, immediately used
27
Q

How would you describe chimps in how they approach problems?

A

“contemplateive”

-take many trials to learn, but sometimes adjust to change

28
Q

Only ______ ________ apes regularly “subassemble”

A

human enculturated

29
Q

What primates display numerosity?

A

chimps and orangutans tested

30
Q

What can we say about numerosity in primates?

A

of those tested, can learn to associate numerical symbols with quantities up to about 9

31
Q

(True/False) Chimps can spontaneously add numbers

A

True; once master numerical associations

32
Q

What is the greedy giveaway task?

A

Chimps previously trained with numerals:

  • presented with 2 piles of M&Ms, one large, one small
  • whichever pile pointed by pointer chimp to is given to other chimp
33
Q

What are the results of the greedy giveaway task?

A

chimps fail unless use numerals in place of piles

-suggests symbol intervening between animal and treat enables delayed response

34
Q

What was unique about the language trained chimp, Sarah?

A

-immediate success on proportions and functional analogies

35
Q

How would the Weigl Principle be important in the wild?

A

be able to distinguish details in group so can distinguish between ally, parent, or child

36
Q

What would be a use of visible displacement in the wild?

A

see food going into mouth of another primate and disappear

37
Q

What would be a use of invisible displacement in the wild?

A

watch hand disappear into the hand of another , who then moves away with it

38
Q

On numerosity tasks, chimps perform better than what other test subjects?

A

college students

39
Q

What is a typical numerosity test?

A

once number trained, briefly see series of numbers, must touch squares in order

40
Q

What is an example of a transitivity test?

A

trained to choose A over B and B over C; tested chose A over C

41
Q

What are the possible social implications of transitivity?

A

deduce relative rank among social group

i.e. A dominant over B, B dominant over C, A dominant over C?

42
Q

What were the reversal learning tests?

A

train conditional discrimination, reverse, teach again

43
Q

What were the results of the reversal learning tests?

A

after first reversed trial, changed response strategy

44
Q

What were the results of the conditional MTS?

A

Primates do not show transfer between problems; primates see first problem as relational, so second is not “same problem” to a primate

45
Q

What are the results of the oddity test?

A

monkeys show transfer, see what matches to go to next trial; apes show first trial success
