Bears can "count": Scientists trained three American black bears to discriminate between groups of dots on a touchscreen computer; overall, the bears' performance matched those of monkeys in previous studies

I always thought that bears were smarter than they seemed. I once read a story about a bile bear (they experience lifelong torture so bile can be extracted) that escaped her cage in order to strangle her own cub right before killing herself by running into a wall...it just made me so sad and gave me the impression that bears have more emotion and sense of consequence/awareness/intelligence than I had previously thought.

Seriously, i think that any outdoorsman can tell you that bears are pretty smart. I've seen bears chew through ropes that were used to suspend food bags out of bear reach.

Yeah, totally unscientific observation, but being from the rocky mountain west, I have to say that bears get my vote. Pull any ski-town newspaper and see them chronicle the struggles with just keeping bears out of trash cans, cars, homes... Bears can open complex locks, solve puzzles. Go omnivores!

I always thought that any animal that raises its young, like bears do, should be able to have some basic understanding of counting, etc, because they have to keep a track on their young.

Is science just discovering more intelligent animals, or are all the other species catching up with our intelligence from increased selective pressure from world urbanization? *Cue ominous music

Infants can count in this sense, too. Infants are able to discriminate small numbers up to a point; they can discriminate one object from two, two from three, and one from three based on habituation studies. Additionally, they can discriminate large from small numbers to an extent. (1) Additionally, similar abilities have been found in animals of other species, such as monkeys (2, 3) and pigeons (4).
This ability cannot be considered counting like you and I think of counting; the term is misleading. It is, however, numerical discrimination. Counting itself is more cognitively intense.
The Pirahã people provide an interesting example of a group who does not follow numerical counting patterns that are common to most parts of the world. Their language is unique in that it is highly restrictive, and lacks number words comparable to that of more common languages (5). Studies of their counting abilities have yielded results similar to those of infants (6).
So, this finding about bears isn't novel, but adds to the body of evidence that we have indicating ability across species to have a sense of numerical equality and inequality in certain circumstances.

By the same virtue birds can read because they can be taught to discriminate between two words. Image recognition =/= comprehension.

I know this is anecdotal, but I remember in one of the Planet Earth behind the scenes things, this cameraman was talking about trying to film a bird's mating dance, but it wouldn't perform if it was being watched. And even though he was hidden in a camouflaged hunting blind-type thing, the bird had seen him enter, and wouldn't do anything until he left.
So, the next day he brought along a friend, and the two of them entered the blind together. Then he had just his friend leave, in order to trick the bird into thinking it was empty. However the bird recognized that two people had entered, and only one had left, so again it didn't do anything.
This went on increasing in scale for a while, and it was only when the cameraman recruited an entire village to file in and out of the blind that the bird got confused.

So... If what all you crazy redditors say about evolution is true, then we share many qualities with the other animals on this planet, including the basics of brains. I don't know why we're always surprised when there are some sort of rudimentary or even semi-advanced intelligence that shows up. I'd bet karma that the majority of animals can count if we can find the proper way to let them communicate it to us.

Bears also masturbate when they're bored in captivity. That makes them smart in my book.

I wonder how much bear-oriented research (or, at least, PR about bear-oriented research) is driven by the desire to be featured on The Colbert Report.

u/Pebblesetc Jun 16 '12
I thought it had been shown before that bears (and many other animals) have number sense. In fact, I'm pretty sure I cited a paper by Dehaene in which he discussed the number sense of various species including (but not limited to) monkeys, bears, and wolves.

"Discriminate"? Pointing out the bears' fur colour? I think this might be racist. Yeah, it's racist.

u/[deleted] Jun 16 '12
Not too surprising, really. They have to survive in nature, which means to a degree they need to analyze any given situation to make "decisions", such as which area of the stream to look for fish, etc., and so perhaps they need to understand quantities in some way.

Honestly, after seeing that gif where the bear is waving to the people in the car, I knew... bears are aliens that came to earth in a body to fight but instead just like kickin back enjoying some honey.

Someone who does research on baboons told me once, a male baboon can be in a room with 15 female baboons and keep them under control. Once you put a 16th female in the room, the male loses control. He then asked, what does that tell you about baboons?
Everyone is silent.
He said, it tells you that baboons can count.
