rjshirts writes "In further proof that Planet of the Apes is coming to pass, researchers in Stockholm, Sweden have proof that primates can plan ahead.
From the article:
'Santino the chimpanzee's anti-social behavior stunned both visitors and keepers at the Furuvik Zoo but fascinated researchers because it was so carefully prepared.
According to a report in the journal Current Biology, the 31-year-old alpha male started building his weapons cache in the morning before the zoo opened, collecting rocks and knocking out disks from concrete boulders inside his enclosure. He waited until around midday before he unleashed a "hailstorm" of rocks against visitors, the study said.'"

Because building a nest is genetically wired into the bird. Make the bird sterile, and it'll keep building nests anyway. Moreover, it's a behavior which has existed for millions of years. It's a completely different phenomenon than a chimp learning to use objects as weapons.
The big thing is that it demonstrates that chimpanzees have some rudimentary understanding of time. He's obviously able to observe his current situation, remember it as a past event, detect a recurring pattern, deduce that it's likely to repeat in the future, decide on an action to be carried out at a future time, and prepare materials required to carry it out. That's no small feat.

A bird doesn't learn how to build a nest. Neither does a spider acquire the experience to spin a web after experimentation. That knowledge is built into them and is instinct, and not cogent though in spite of your high blown words like "multi dimensional gradient" and "quantization".
Without a doubt, the chimp in question learned a pattern. I leave it as an exercise to you to guess what that pattern was.
The distinction between instinct and cogent thought is very real unlike what you imply. If spiders had to learn how to spin a web, they would starve, and so in their case, cogent thought is neither needed nor important.

Another way to look at it is that birds that didn't think they had to build nests to lay eggs in didn't pass on their genetic wisdom since they had no one to pass it on to. So that trait was naturally selected out. At least it can be argued that birds didn't learn to build nests by having experimented with laying eggs without one and then realizing that they actually needed one!
However, stockpiling stones to fling at visitors aren't (in an obvious way, at least) something that is naturally a survival instinct. Flinging whatever is within reach is - fight or flight. However, foreseeing and preparing for a fight is not. Especially in the environment of a zoo, to which the chimps have only been subjected to for only for about a few hundred years. It had to have been learned. In their lifetime.
So, wordsmitthing aside, there is a difference and as the parent pointed out - it has to do with learning and applying that knowledge to an anticipated future event.

I have actually seen our dog understand how to catch rodents. The insight was an obvious watershed, because he went from zero successes over 5 or 6 years, to multiple successes per month for the rest of his "active" years after the realization:
Over here we have a type of rodent(in swedish they are called Skogssork, similar to or the same as Bank Voles) which creates a nest for its family by digging tunnel systems in the dirt. These tunnels can be several meters long so the Voles can exit the nest at many places.
Our dog had for many (annoying) years stood barking with his nose stuck down any of the tunnel openings, trying to dig his way to the Voles. He did this for hours at end and it was his best passtime.
One day when he had barked into an opening, I happened to be nearby and I saw a Vole exiting the nest by an opening far away from where our dog was, it having reacted to the dogs threat. I called out to our dog to chase it. Our dog saw the Vole and tried to get it, but could not catch it in time before it went underground again.
Now comes the cool thing:
He then (after years of stupid barking down tunnel openings), went to the opening where the Vole had gone in, barked really loud, and then silently snuck back to the opposite side of the nest where he waited silently. After many years of pointless barking, he finally caught his first Vole. After that day our dog regularly brought home Voles, because he had understood how to outthink his rodent enemy.

Years ago I read about some animal sanctuary where they were trying to keep chimpanzees in captivity. They had to run the place like a real jail for humans. If you forget to lock a door in (say) the elephant enclosure at the zoo you would be okay for a while. Not so with chimps.

I think the key here is that the chimp anticipated future events and planned rather than just showing an understanding of the current situation, which are dramatically different capabilities. A chimp realizing the door is unlocked is one thing, that is interesting enough given what we usually think of non-human intelligence (I'd say ignorance rather than arrogance, I'm not around a lot of chimps). It's another to demonstrate that the chimp can forecast events that haven't occoured yet, this is something that humans seem barely capable of.
Maybe something in TFA backs me up on this... Holy crap, suprise of suprises, IT DOES!
To be honest, I'm suprised that you're suprised that people who study chimps are suprised by this. These seem to be people who know chimps pretty well, if this were an old result, you'd think they wouldn't be wasting their time. Whenever I've thought an expert in a field I don't know as well is wasting their time, I usually come to realize that I was actually not understanding the situation.

Any zookeeper who has ever worked primates would tell you that this is pretty typical.
My wife worked as a keeper at a prominent chimp and orangutan sanctuary for several years. She would come home with tales that would make your skin crawl of how smart the apes (both chimps and orangutans) are. It turns out that the OUs (you don't say "orangs", as it offends some of the more hard-core keepers) are the more cunning of the two -- she likened them to engineers.
Some examples:
Did you know that the apes you see in TV ads (such as CareerBuilder) and films (such as Dunston Checks In) are never more than 3 or 4 years old, but have a lifespan only a little shorter than humans? They're only "cute" when they are very young, and quickly become uncontrollable, no matter how well-trained they are -- precisely because they have that kind of intelligence. (Roughly that of a 4- to 6-year-old child.)
After that, they are retired and put in cages (rarely zoos) for the rest of their lives. The entertainers wash their hands of them, then your tax dollars are spent to maintain them for the next 40+ years. Depending on the facility, this can be as much as $20,000USD per ape per year.
So every time you see a "funny monkey video", think about how much of your paycheck is going to support that ape in a few years.

You are under the assumption that it is planning that causes an animal to prepare to hibernate and not pure instinct leading them by the nose.
You don't eat because you realize that if don't various mechanisms in your body are going to fail. You eat because you are hungry. The same is true for hibernation, mating, and a pile of other "planned" behaviors. Two deer don't bang in the fall because they realize that this is their chance to make babies and if they miss the window they will have none. They got at it because they are horny.

What exactly makes you think they don't learn from their parents? Squirrels don't exactly grow up in a vacuum.
I have plenty of ground squirrels [wikipedia.org] around, and they are fairly independent animals; they run alone, maintain their personal space, and when they meet it's usually to fight. They do maintain a collective behavior (when a hawk shows up, for example.) However nobody can learn from experience that one hasn't experienced before; and squirrels are not very good in "instruction", whatever you mean by that :-) - it would require fairly elaborate communication between generations, and already in April or May young squirrels live on their own, dig their burrows and such.
Again, the issue here is that an animal has one and only one chance to make a correct "life vs. death" decision when winter comes, and that decision (gathering food and fattening up) has to be made well ahead of cold time. To make matters worse, this decision is counter-intuitive, since the young squirrel never saw a winter and never participated in preparations. A lone human could figure out the need by reading books; a child could be told to do that by adults; but a small rodent does not have access to such complex communication mechanisms, and by nature is not a herd animal to blindly follow a leader. Other animals, like deer or sheep, are far better in introducing their young to the world.

In the fox case, for instance, the fox might be thinking ahead, and storing food for the future, or foxes might have a "when not hungry, bury available food" instinct. This doesn't mean that the fox isn't planning ahead; but you can't tell one way or the other.
Thus, researchers are always on the lookout for situations that can distinguish between the two. Novel situations where instincts wouldn't be expected to apply, pathological situations where instincts would fail if applied, etc.

I wonder, do researchers do this instinctively or is it a cognitive process? If they are always on the lookout for these situations, then that suggests to me that it is instinctive, and that these instincts have helped lead them to succeed as researchers.

Any kid with a subscription to zoobooks can tell you about arctic foxes burying portions of a kill for later use during winter.
There is a VERY important difference here. Arctic foxes don't survive through a few winters without a food cache and think "hey I bet it's going to do that again next year, maybe I should stash some food this summer so I have more to eat next winter?". Evolution has taught them to do that. Same as any other instinctual behavior in any other animal. Babies don't learn to suck the tit.
These chimps identified a pattern, and prepared in advance to benefit themselves when they expected it to repeat. Gathering rocks in the morning to attack tourists in the afternoon is not evolutionary adaptation. Something like that could become an evolutionary behavioral adaptation, but not from 100 years of zoos.
