The term "episodic memory" was introduced by Tulving to refer to what he considered a uniquely human capacity — the ability to recollect specific past events, to travel back into the past in one's own mind — as distinct from the capacity simply to use information acquired through past experiences. Subsequently, Clayton et al. developed criteria to test for episodic memory in animals. According to these criteria, episodic memories are not of individual bits of information; they involve multiple components of a single event "bound" together. Clayton sought to examine evidence of scrub jays' accurate memory of "what," "where," and "when" information and their binding of this information. In the wild, these birds store food for retrieval later during periods of food scarcity. Clayton's experiment required jays to remember the type, location, and freshness of stored food based on a unique learning event. Crickets were stored in one location and peanuts in another. Jays prefer crickets, but crickets degrade more quickly. Clayton's birds switched their preference from crickets to peanuts once the food had been stored for a certain length of time, showing that they retain information about the what, the where, and the when. Such experiments cannot, however, reveal whether the birds were reexperiencing the past when retrieving the information. Clayton acknowledged this by using the term "episodic-like" memory. 1 B 1. The primary purpose of the passage is to A. explain how the findings of a particular experiment have been interpreted and offer an alternative interpretation B. describe a particular experiment and point out one of its limitations C. present similarities between human memory and animal memory D. point out a flaw in the argument that a certain capacity is uniquely human E. account for the unexpected behavior of animal subjects in a particular experiment 2 C 2. According to the passage, Clayton's experiment depended on the fact that scrub jays A. recall "when" and "where" information more distinctly than "what" information B. are not able to retain information about a single past event for an indefinitely long period of time C. choose peanuts over crickets when the crickets have been stored for a long period of time D. choose crickets over peanuts whenever both are available E. prefer peanuts that have been stored for a short period to crickets that have been stored for a short period 3 C 3. The passage suggests that Clayton's experiment demonstrated scrub jays' ability to A. choose different storage places for different kinds of food to minimize the rate at which a food will degrade B. unlearn a behavior they use in the wild in order to adapt to laboratory conditions C. bind together information about different aspects of a single past event D. re-experience a past event in memory and act accordingly E. distinguish one learning event from a subsequent learning event 4 A 4. It can be inferred from the passage that both Tulving and Clayton would agree with which of the following statements? A. Animals' abilities to use information about a specific past event are not conclusive evidence of episodic memory. B. Animals do not share humans' abilities to reexperience the past through memory. C. The accuracy of animals' memories is difficult to determine through direct experimentation. D. Humans tend to recollect single bits of information more accurately than do animals. E.

Hey Guys,

"Such experiments cannot, however, reveal whether the birds were reexperiencing the past when retrieving the information." - I am having trouble deciding whether this line is an opinion stated by the author or if its just an observation made by the author.

It would be great if anyone can help me understand this better

Hi mamaan,

If we read the following lines: "Such experiments cannot, however, reveal whether the birds were reexperiencing the past when retrieving the information. Clayton acknowledged this by using the term "episodic-like" memory.", we can infer that its neither the author's opinion nor his observation. Its just a statement that he puts forward, as viewed by Clayton, since in the next lines author mentions that Clayton acknowledged this behavior of birds using the term "episodic-like" memory.

Hope this Helps.
Thanks.

Hi VeritasKarishma GMATNinja

Could you please share your opinion on Q4?

Quote:

4. It can be inferred from the passage that both Tulving and Clayton would agree with which of the following statements?

A. Animals' abilities to use information about a specific past event are not conclusive evidence of episodic memory.
Nothing is mentioned about animals in Tulving remarks.[color=#ff0000]so why this is correct option[/color]?

Quote:

B. Animals do not share humans' abilities to reexperience the past through memory.

WHY NOT CORRECT:
by Tulving to refer to what he considered a uniquely human capacity ( uniquely human capacity means: not available among animals)
by clayton: Such experiments cannot, however, reveal whether the birds were reexperiencing the past when retrieving the information. Clayton acknowledged this by using the term "episodic-like" memory.

Quote:

E. The binding of different kinds of information is not a distinctive feature of episodic memory

WHY NOT E?
by Tulving : as distinct from the capacity simply to use information acquired through past experiences.
Clayton acknowledged this by using the term "episodic-like" memory.

VeritasKarishma - I am not able to understand what author is trying to convey with below contrast.

Such experiments cannot, however, reveal whether the birds were re-experiencing the past when retrieving the information. Clayton acknowledged this by using the term “episodic-like” memory.

Can you please explain this part of the sentence and how it relates back to the entire passage ?

Tulving introduced the term "episodic memory" to mean revisiting the past in your mind. This is different from learning from past experience. It is going back in the past. As per Tulving, "episodic memory" is unique to humans.

Clayton et al. developed criteria to test for episodic memory in animals.

The experiments found something.

Such experiments cannot, however, reveal whether the birds were reexperiencing the past when retrieving the information. So we cannot say that the birds have "episodic memory".
(This is Author's Opinion.)

Clayton acknowledged this by using the term "episodic-like" memory.
The author says that Clayton also acknowledged what he, the author is saying by using the term "episodic-like" memory and not "episodic memory". That Clayton also said that birds display "episodic-like" memory.

Sorry guys. I don't have OA. But here is my explaination.
4. A
B is very close. How to refute (B)?
Tulving said that "episodic memory" is a uniquely human capacity, so it is not in "animal." Clayton's only refers "episodic-like" memory in animal.

According to the passage, Tulving consider this type of capability " a uniquely human capability", which mean only humans have this kind of capability. At the same time, Clayton thinks he cannot decide whether the birds were experiencing the past when retrieving information--in other words, Clayton thinks he cannot decide just based on the experiment itself. So they both agree that the experiment cannot prove that animals have "episodic-memory".

Hi, Can you help with Q2. C and E

Certain length of time could mean either short period or long period.

plumber250

Hi There,

Seems to be a few questions over Q 4. Let me see if I can help.

4. It can be inferred from the passage that both Tulving and Clayton would agree with which of the following statements?

Here are the answer choices:

A.Animals' abilities to use information about a specific past event are not conclusive evidence of episodic memory. This is correct. Tulving says episodic memory is for humans only, and Clayton says that his work on Jays is uncertain so calls it 'episodic like'. So neither CONCLUSIVELY argues for this.

B.Animals do not share humans' abilities to reexperience the past through memory. Incorrect. Clayton's research suggests they may be able to

C.The accuracy of animals' memories is difficult to determine through direct experimentation. Incorrect. This may or may not be true, we don't have evidence for this

D.Humans tend to recollect single bits of information more accurately than do animals.Incorrect. As per C, we don't have evidence on this in the passage

E.The binding of different kinds of information is not a distinctive feature of episodic memoryIncorrect. We do not see 'binding' mentioned at all under Tulving, it is only mentioned when we talk about Clayton.

So overall, when looking at this question there are 2 things I take away.
1) In answer A we have the word 'conclusively' - this is often a give away word, it requires a very high level of proof
2) In this passage we only talk about Tulving for a very short period - the majority is on Clayton, so for Tulving and Clayton to agree, we have to find evidence in the Tulving section - as this is short, it's easy to work it out.

Hope this helps...

Explanation

3. The passage suggests that Clayton's experiment demonstrated scrub jays' ability to

Difficulty Level: 550

Explanation

The passage discusses Clayton's experiment involving scrub jays and their ability to remember and retrieve information about the type, location, and freshness of stored food. The key point of the experiment is that scrub jays were able to retain and use multiple components of a single event, namely the type of food, where it was stored, and how fresh it was. This ability to retain and use various aspects of a single event together is referred to as "binding" in the context of episodic memory.

Now, let's explain why the other options are incorrect:

A. choose different storage places for different kinds of food to minimize the rate at which a food will degrade
While the experiment involves different storage places for different types of food, the main focus is on the scrub jays' ability to remember and bind together various aspects of a single event (type, location, freshness), not on their strategy for minimizing food degradation.

B. unlearn a behavior they use in the wild in order to adapt to laboratory conditions
The passage does not suggest that the scrub jays unlearn a behavior from the wild. Instead, it highlights their ability to remember and use information about stored food and the conditions under which they switch their food preference.

D. re-experience a past event in memory and act accordingly
The passage does not indicate that the scrub jays are re-experiencing past events in memory and acting accordingly. It focuses on their ability to retain and use information about various aspects of a single event.

E. distinguish one learning event from a subsequent learning event
The passage does not discuss the scrub jays' ability to distinguish between different learning events. It primarily focuses on their ability to bind together information about various aspects of a single event (food type, location, freshness).

In summary, based on the information provided in the passage, option (C) is the correct answer because Clayton's experiment demonstrated scrub jays' ability to bind together information about different aspects of a single past event.

Answer: C

Explanation

4. It can be inferred from the passage that both Tulving and Clayton would agree with which of the following statements?

Difficulty Level: 700

Explanation

The passage discusses the introduction of the term "episodic memory" by Tulving, which refers to the uniquely human capacity to recollect specific past events and travel back into the past in one's own mind. Subsequently, Clayton developed criteria to test for episodic memory in animals, which involves the binding of multiple components of a single event. Clayton's experiment with scrub jays focused on their ability to remember "what," "where," and "when" information about stored food based on a unique learning event.

While the experiment demonstrated that scrub jays can retain and use information about specific past events, the passage makes it clear that such experiments cannot determine whether the birds were reexperiencing the past when retrieving the information. This is why Clayton used the term "episodic-like" memory.

Both Tulving and Clayton would agree with the statement in option A because their work indicates that the ability to use information about a specific past event, as demonstrated by animals, does not necessarily provide conclusive evidence of true episodic memory as understood in humans. This is evident from the passage's discussion of Clayton's experiment and the limitations of such experiments in fully capturing the nature of episodic memory.

Now, let's discuss why the other options are incorrect:

B. Animals do not share humans' abilities to reexperience the past through memory.
The passage does not explicitly suggest that animals cannot reexperience the past through memory. While it acknowledges that the ability to reexperience the past is a uniquely human capacity, it does not make a direct comparison between humans and animals in this regard.

C. The accuracy of animals' memories is difficult to determine through direct experimentation.
The passage does not focus on the difficulty of determining the accuracy of animals' memories. It mainly discusses the criteria developed by Clayton to test for episodic memory and the specific findings of his experiment with scrub jays.

D. Humans tend to recollect single bits of information more accurately than do animals.
The passage does not make a direct comparison between the recollection abilities of humans and animals. It primarily focuses on the concept of episodic memory and the criteria used to test it in animals.

E. The binding of different kinds of information is not a distinctive feature of episodic memory.
This statement contradicts the passage's main point, which emphasizes that one of the distinctive features of episodic memory is the binding of multiple components of a single event. This concept is central to the discussion of both Tulving's and Clayton's work.

In summary, based on the information provided in the passage, option A is the correct answer because both Tulving and Clayton would agree that animals' abilities to use information about specific past events are not conclusive evidence of true episodic memory as experienced by humans.

Answer: A

Additionally these explanation may also help you.

Question 2

sayan640

Yes..both option C and E are close...GMATNinja , KarishmaB , could you please provide your explanation for the question no. 2 ?

Garima999999999

Hi, Can you help with Q2. C and E

Certain length of time could mean either short period or long period.

Question 2 asks about the experiment with the scrub jays. In this experiment, peanuts and crickets were stored separately. Jays prefer crickets, but unfortunately crickets degrade more quickly than peanuts. So, do jays remember to go to the place with the peanuts once the crickets have gone bad?

Sure enough, they do switch to peanuts. This shows that they remember what was stored, where it was stored, and when it was stored. From this, Clayton concludes that scrub jays have "episodic-like" memory.

Which answer choice reflects this?

Quote:

C. [Scrub jays] choose peanuts over crickets when the crickets have been stored for a long period of time

This is exactly what we need! The conclusion that scrub jays have "episodic-like" memory depends on the fact that the jays choose peanuts when the crickets have gone bad.

Compare that to (E):

Quote:

E. [Scrub jays] prefer peanuts that have been stored for a short period to crickets that have been stored for a short period

This is the opposite of the logic of the experiment. The experiment depends on the fact that jays prefer crickets in the short term, and only switch to peanuts when the crickets have gone bad.

(E) is out, and (C) is the correct answer to question 2.

I hope that helps!
