Study Points to Sixth Sense in Humans 587

Posted by CowboyNeal from the sight-beyond-sight dept.
Ben Sullivan writes "St. Louis researchers say there's something to the notion of a 'sixth sense' in humans. A part of the brain known as the cingulate cortex, they've found, likely combines multiple, sometimes unconscious data streams to come to conclusions and send warning signals to the conscious mind. Example: Aboriginal tribesmen somehow sensed the impending danger of December's tsunami in time to flee to higher ground before the first sign of water."

      Although it does seem that aboriginal people were forewarned, this is more responsibly attributed to their tradition of paying close attention to wildlife. While it is not well understood, animals seem to be more sensitive to the subtle environmental changes that precede events like earthquakes and tsunamis, and it's very smart of these people to take notice when the animals all flee to higher ground.

      In a report on NPR, (and I can't get more specific because I was driving), it was stated that there are little used nerve endings in our knee cartilage that evolved specifically for the purpose of detecting earth tremors. I can remember one time in my life when I sensed a very faint earth tremor (I live in a geologically stable region) and I sensed it through my knees, as I recall (I confirmed it via a news report later). Tribal people, living in a quiet setting, are probably more attuned to the sensations delivered by these nerves. Also, if their ears are very keen (not damaged by headphones, machinery, and too-loud speakers, as mine are), perhaps they could detect infrasonic sounds associated with an earthquate of the extreme magnitude of that one. Animals certainly are very good at detecting infrasonics, so the tribal peoples could have noted animal movements prior to the tsunami.

      I agree with you but there is some merit in this. Not enough to make a story called "the sixth sense" though.

      All IMHO, the brain is a humongous pattern matching system. It learns by ways of emotional or genetic reinforcment. It might very well be that in fact seeing animals flee, even if they're just walking uphill might trigger a dormant pattern and pop up a completely irrational thought that maybe it's time to go up too.

      But this is the equivalent of software. Not an additional hardware function that perceives stuff (the sixth sense). That would be like calling intelligence your 7th sense.

        I agree with you, both in the claim that this phenomenon is not psudoscience, and that calling it a "sixth sense" is somewhat sensational.

        The article spells out the test methodology in detail, and it seems solid.

        But I have personal experience with this.

        I have had extensive navigation training, first as a pilot, and then later in a military career. The Army in particular had very high standards for needing to know exactly where you were at all times (to within 100m) without the aid of something like a GPS.

        So you learn to keep a visualization of your surroundings in your head, and to cross-reference that visualization against whatever tools you have (like a map, compass, or odometer) at regular intervals to keep the internal representation in sync with the real world. After some practice, this becomes second nature - muscle memory stuff.

        But there's an odd side-effect, at least there is with me. If I make a wrong turn, miss an exit, or make some sort of navigational mistake, something in my subconscious will pick up on it well before I'm ever consciously aware of it (especially if my conscious is somehow distracted away from navigation) It's hard to put into words... but I will get a profound sense of "wrongness", like an inaudible alarm bell. The more I ignore it, the worse it gets.

        I have learned not to ignore it. If that alarm goes off, I'll immediately make navigation the highest-priority mental task - and without fail, I will have just goofed somehow.

        Unfortunately, this ability does not convey any other information other than "you are no longer on the planned course". There is a recognition function in there, but no follow-on advisory function. It's still up to conciousness to correct the problem once discovered.

        When it happens though... it's really a very odd feeling, and it's quite strong.

      Some of the local indigenous people had stories handed down over generations from their ancestors who had also suffered through a tsunami, and from these stories some of them recognized the warning signs and knew what to do. No mystical explanation required in that case.

      A good example of the value that even conventional science holds over anything paranormal is the 10-year old British girl who recognized the warning signs from having listened in her geography class, and saved hundreds of lives by warning those on the beach and nearby hotel to evacuate.

      By comparison: Even though there are millions of psychics/clairvoyants and other people who claim to be able to predict the future worldwide, not one predicted the tsunami! Remarkable?

      This is not to say that there isn't something to the study descibed in the article; animals and aboriginals may all have 'felt' the earthquake (even from far - elephants' feet for example have specially adapted sensors that are very sensitive to vibrations), and just thought it prudent to get out of the way just in case. However the use of the term "sixth sense" implies a paranormal explanation, when in fact you can pretty much bet that the true explanation, whatever it turns out to be, is going to be quite logical and rational. This is perhaps more likely just poor journalism rather than poor science.

      (These stories with a 'pseudoscientific bent' seem to reveal a creeping trend away from rational thinking on slashdot, which several years ago used to feel like one of the few good places on the Net where one could get away from that sort of gullible mainstream uninformed discourse :/ Is Slashdot now officially "mainstream"?)

      In addition to what I just said, I also read TFA and found this:
      Researchers provided study participants with a series of blue or white cues and asked them to push one button or another depending on the direction of arrows. Brain imaging suggested that an area of the brain had learned to recognize that blue cues indicated a greater potential for error, thus providing an early warning signal that negative consequences were likely to follow their behavior.

      The rest of the article says essentially the same thing -- the brain learns to recognise a pattern of making mistakes, not that is able to sense impending danger before it happens or whatever.

      Yeah, the whole "five senses" thing is crap from ancient greek philosophy. It's more accurate than their "four elements", but it's still not correct. There are numerous other senses. Balance (as you mentioned), sensed by the motion of fluid in the inner ear; proprioception/kinesthesia (as another poster mentioned), sensing body position; There are several "internal" senses-- hunger, full bladder, etc.-- as well. Basically, anything that your nervous system consciously registers (internal or external) is a sense. Technically, that tingling feeling you get just before a lightning strike during a thunder storm could be called your "sense of lightning".

          I've always felt those "five senses" were an overgeneralization. I mean, taste and smell are basically the same thing, aren't they? As I understand it, smell is basically your nose "tasting" molecules captured from the air. Your sense of taste, meanwhile, is pretty hampered when you plug your nose.

          Isn't hearing basically a type of interpreted "feeling"-- your inner ear contains small hairs that feel the compression of air, which are then experienced as sound.

          Since people are talking about phantom-limb, I think one might also mention the reverse-- the sense that your body extends beyond its normal self-- ie, that weird feeling that you've 'fused' with a car/game/musical instrument so that they feel like an attachment or extension to you-- that you become so comfortable with them that you don't think of the interface between you and that object.

          When I'm driving for long periods of time, I do sometimes feel as though the car has become to some effect an extension of my body. To move the car, I don't conciously think that I need to use my arms to turn the wheel, I just kind of will the car to turn, and my arms do what's necessary. I've had this experience with video games as well. In a way, your brain accepts that you've become part OF that object. Another example-- once I learned to type, I no longer needed to think about the mechanics of typing, the words just kind of flow to the screen as I think them.

          I guess one's brain just adapts itself to your physical "hookup" and tries to streamline the input and output streams so that they are as efficient as possible.

          So, yeah, I agree that the 5 senses idea seems kind of over-simplified. I suspect that whatever your nerves are wired to, after along enough your brain will adapt enough to accept it as a source of "input". I'm sure this has been tried. Does anyone know of an experiment like this one [cnn.com] where a person's senses were "extended" via hardware?

          And what about that creepy-- and often annoying-- feeling that someone's reading over your shoulder? That "feeling" that you're being watched? What's that all about? Which of the five senses is used to describe THAT? ;)

    Calling this a "sixth sense" is very misleading. The normal five senses - sight, hearing, touch, taste, and smell, for those few who don't already know - involve the intake of information through specialized organs or tissues (eyes, ears, skin, etc.) in addition to the processing of those stimuli. This so-called "sixth sense" is simply the subconscious reprocessing of the same information obtained by the regular five senses (and that description misses the real point of the discovery anyway*), and so it hardly qualifies as a sense.

    * The point of the discovery is that the region of the brain discussed in the article helps to determine, based on past experience and the current situation, whether something is a bad idea or not.

    It's true that there is definitely a region of the brain that manages anxiety - and that all sorts of things can make people anxious - seemingly for no reason!

    However, neurotic != psychic. There are no *new senses* under discussion here, just a better understanding of how the brain manages that feeling of impending doom you sometimes get.

    Do other mammals have similar brain structures? Yes.

    Do they probably use them to avoid danger, incl. forest fires and tsunamis? Almost certainly.

    Do we, higher mammals, probably retain whatever hard-coded sensory cues cause our little forest friends to flee natural disasters? We probably do, yes. When someone is in the supermarket and they have a panic attack for no reason, might it be because the kiwi display is triggering the same mechanism that is supposed to make us flee from a tsunami? Maybe.

    "In the past, we found activity in the ACC when people had to make a difficult decision among mutually exclusive options, or after they made a mistake," Brown said. "But now we find that this brain region can actually learn to recognize when you might make a mistake, even before a difficult decision has to be made. So the ACC appears to act as an early warning system -- it learns to warn us in advance when our behavior might lead to a negative outcome, so that we can be more careful and avoid making a mistake."

    What about the guys who "got a feeling" they should head to higher ground when there wasn't a tsunami coming? What about the guys who didn't get a feeling when it was?

    People get feelings and act on them all the time. We only hear about the rare times when they coincide with an actual event.
  • Don't we have six senses anyway - sight,hearing,touch,taste,smell and time. Our sense of time passing may be wildly inaccurate at times, but I can 'sense' the difference between a day and a minute pretty easily. Presumably there's some sort of time-keeping circuitry in the brain somewhere.

    That would make this the seventh sense, unless there's some reason that time is never included.

  • The human mind really is a fascinating thing. Think about all of the things that you perceive during the day. All the sights, smells, tastes and everything else. You're continually bombarded with so much information that you cannot possibly be paying attention to everything coming in. Doesn't it make a certain amount of sense for evolution to put some sort of mechanism into the brain to help collate those little signs that you would otherwise ignore into a larger, more apparent picture if it adds up to

    ...rather than a sixth sense. Just as many have pointed out, it's still the 5 senses that are doing the input gathering here -- it's just that another part of the brain is doing some number crunching.

    I liken it to Bayesian because it seems to be based on analyzing what happened in the past in order to attempt to predict what is *going* to happen in the future.

    Stuff with these characters are often spam, let's bump this score up a bit.

    Everytime x happens, y seems to happen afterwards, so I should flee.

    This isn't magic, guys. It's just another advantage of the subconcious doing work behind the scenes. /., like Wired, is just prone to blowing these sorts of stories out of proportion.

    While I personally believe in a Sixth Sense. I remember reading that Indian tribespeople avoided the tsunami for two reasons:

    1) Their land was not deforested and the trees slowed down the onslaught of the waves.

    2) An ancient legend warns them to seek higher ground when the ground shakes.

    Thus, all of them survived.

    This is like saying we've discovered a second Mac mouse button just because you can make more use of the single one you've got if you're smarter and more experienced, or because you're so used to using the control key that you're no longer conscious that you're doing it.

    Even CNN was able to report this diligently. They passed on knowledge through their generations that retreating water was a sign of disaster, so when the waters went out (whatever the technical term is) they all scarpered.

    I am sure the brain does have sub systems that try and trigger responses from us, like when we tune into a baby crying or other things, I am sure that our senses are more sensitive than we realise, but mostof it is filtered out.

    Sounds like headline grabbing terminology bending.

    But saying it is a sixth sense does not mean that IT KNEW MORE than what was being told to it by the 5 senses we do actually have (perhaps we can like pigeons sense magnetics also).

    So please, like robotics, nanotech and every other buzz word that gets recycled, make sure you really are saying what you are saying.

    Interestingly, an article in the Washington Post (can't find it now) mentioned that one particularly old tribe of fisherman also fled, but only after the waters receded (the ultra "low tide" effect that occurs before the tsunami hits). Apparently, folk stories passed generation-to-generation included references to ancestors who experienced tsunami. Armed with this cultural folklore, they fled while others gawked at the strange sight of the sea leaving the shore.

    So could all of you who are whining about the paranormal and pseudoscience just calm down and read it?

    They're using the term "sixth sense" because that's what many people call this ability - and attribute it to psychic, mystical phenomena. They're using the colloquial name for it, but demonstrating what it really is - an ability to subconsciously process subtle clues that you're not even consciously aware of, and use them to determine when danger is coming. The article makes no claims of psychic powers or mysticism or paranormal activity - if anything it's the opposite. It's like showing that people don't get sick because a bad spirit infested them, but because germs infested them. They're still getting sick, but for a real reason.
