episodic memory

[tanyatomar]

i did not find this passage in search. hence posting this question:


The term "episodic memory" was
introduced by Tulving to refer to what he
considered a uniquely human capacity-
Line the ability to recollect specific past events,
(5) 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
(10) 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
(15) examine evidence of scrub jays' accurate
memory of "what," "where," and "when"
information and their binding of this infor-
mation. In the wild, these birds store food
for retrieval later during periods of food
(20) 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
(25) 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
(30) 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.

Q5:
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



i chose C
however it was mentioned that corect answer is D. i think if they dont choose peanuts over crickets after a long time of storage=> they dont consider time. therefore it shud be C..
anyone knows the correct answer to this one...
this is a GMAT Prep question.

Hi Tanya, The question asks about 'Clayton's experiment depended on the fact'. It does not asks us about what actually happened in the experiment. The basis for Jay's experiment was whenever Jays have an option for Crickets and Peanuts , Jays's will go for Crickets. N because of the episodic memory Jays knew that Crickets would have been degraded, hence they went for peanuts.So i suppose the ans shd be D

ya got it.... :)
thanks a lot:)

The answer should be C instead of D.

D is clearly too extreme as jay does NOT choose crickets over peanuts whenever both are available. The passage states that "Clayton's birds switched their preference from crickets to peanuts once the food had been stored for a certain length of time"

C is correct answer

for this discussion to continue, we need a screenshot of this problem from the FREE gmat prep software.

here the original post has line numbers.
if there are line numbers, then it is quite unlikely that the problem is from the GMAT Prep freeware. (there are no line numbers in GMAT Prep—yellow highlighting is used instead—and it is very unlikely that anyone would randomly add line numbers while transcribing the problem.)

so, screenshot please. thanks.
