Robot Makes People Feel Like a Ghost Is Nearby 140

sciencehabit writes: In 2006, cognitive neuroscientist Olaf Blanke of the University of Geneva in Switzerland was testing a patient's brain functions before her epilepsy surgery when he noticed something strange. Every time he electrically stimulated the region of her brain responsible for integrating different sensory signals from the body, the patient would look behind her back as if a person was there, even when she knew full well that no one was actually present. Now, with the help of robots, Blanke and colleagues have not only found a neurological explanation for this illusion, but also tricked healthy people into sensing "ghosts," they report online in Current Biology (abstract). The study could help explain why schizophrenia patients sometimes hallucinate that aliens control their movements.

        It's science news in that we've isolated a repeatable brain interaction electrical with a specific known effect.

        That's a big deal, because it can begin to allow use to attribute direct cause to some human behaviors. Which has potential therapeutic applications, and maybe even someday can allow us to start the previously impossible task of improving on the human brain.

            You have just committed a fallacy of equivocation. [logicalfallacies.info] You are using two different meanings of the word faith here and trying to say that they are the same when they are not.

            For example, when I drive through a green light without looking I have "faith" that others are not going to drive through the red light and hit me. This is based off of experience and is one defintion of faith, which is a trust based on experience.

            Religious faith is different. It is a belief that is not based on proof.

            Now you may say that you are talking about faith in the individuals(scientists and preachers) which is the same as trust in the individual, but that is a little disingenuous. You are basically relying on extreme ignorance and a severe lack of curiosity in the "believer". In other words you are claiming in this case that you are ignorant of the scientific method and of the importance of evidence. You are also claiming that your mother is ignorant of these things as well as the lack of evidence of the claims of religion.

            I sincerely doubt that you and your mother are that stupid.

            Don't feel bad. Fallacies of equivocation are very easy to fall into in the English language.

            Otherwise, when presented with evidence that the physicists have not done their work well, are not impartial, or are lying to you, you'd continue to believe them, out of faith, rather than altering your opinion and reacting accordingly, which is reason.

            Demonstrating that your mind is the product of your physical brain's functioning is not particularly difficult. You don't even need even any lab equipment. A popular experiment (which anyone can perform, and many do) is to introduce a dose of CH3CH2OH [snowbrains.com] into your brain, and then observe the resulting changes in your mind's behavior. If the mind and the brain were two separate mechanisms, mental changes like those would not occur in response to the introduction of a chemical.

                To the second, you could replace 'drug addiction' with 'need to pee'. The desire to satisfy a physical discomfort doesn't tell us anything about the nature of consciousness other than the fact that people generally prefer to be comfortable.

                • The drug addiction and the need to pee come from the same area in the brain. The drug co-opted that neural substructure to warp the person's motivations. There is a shit-ton of neuroscience evidence to back up both of my claims. You can counter with analogies, but the neurological evidence of brain-based consciousness is solid.

It could do everything, physically process inputs and create outputs, without any need for an observer, someone experiencing the show all the time.

    This doesn't make much sense to me. First off, the test subject knows something else is behind them touching their back. They know there IS a "ghost" there (IE something external from themselves) that is touching their back. The test subject knows from experience that even though they are moving their hand, that motion on their back can't be because their hand is actually back there.

    When the touches are synchronized, and the motion they make with their finger results in the robot touching their back at the same time, the brain coordinates the events and automatically realizes "I just triggered this touch on my back by doing something" and they don't have that sense that something external is behind them.

    When the touch is delayed, the brain does not automatically correlate their action with the sensation on their back, and thus the robot's motions are interpreted as something external (ie a "ghost").

    What doesn't make sense to me is the synchronized motion part is really the trick here - that our brain will automatically figure out we're causing a sensation, even though the mechanics don't make sense or it's something we haven't experienced before. The fact that that or subconscious does not automatically assimilate those motions that are no longer synchronized is to be expected. There IS a ghost behind the person touching them, in the form of a robot, and if the actions are not synchronized, then our mind may not correlate those delayed motions as a result of something we did.

    As soon as those motions are no longer synchronized it gets silly to make the test subject guess how many people are behind them or whatever. Something is poking them in the back, and they don't notice that it's a delayed result of their own motions - it's quite obvious that a robot or person or something is responsible for that sensation. And so different people will make different guesses about what kind of trickery is going on behind their back based on their mental state or perception or whatever.

    Or maybe something about this experiment went WOOSH right over my head.

      It gets interesting later:

      To verify the response, the researchers conducted another study in which four researchers stood in the room. Participants were told that while they were blindfolded and operating the machine, some experimenters might approach them without actually touching them. The researchers told participants to estimate the number of people close to them at regular intervals. In reality, no researcher ever approached the participants. Yet people who experienced a delayed touch on their back felt more strongly that other people were close to them, counting up to four people when none existed.

        Maybe I am blindfolded, but what's interesting about this? Test subjects were blindfolded in a room with people and were told those people would come close to them but not touch them. Then something poked them, which due to desyncronization they could not relate to their actions. So they concluded that someone was poking them. And being in an uncomfortable situation (blindfolded with people in the room, operating a machine of unknown purpose - or did they know it was a poking machine?), being doubtful if th

      I think I understand what they're trying to demonstrate, but the experiment is structured in a way that's not obvious. It starts from the idea that some people who have hallucinations of "ghosts" and other such things have damage in their brain, in an area that coordinates different sensations to determine cause. So it's like, if you were to flick yourself in the leg, you would feel one hand flicking, hear a brief "thud" noise from the impact, and feel an impact on your leg, and there's a part of your bra

      Maybe I'm wrong, but I think this sentence is very important here (emphasis mine):

      If the back-poking was in sync with the participants’ finger movements, they felt as if they were touching their backs with their own fingers

      When the robot finger at the back of a healthy person is in sync with their own finger they can't tell a robot is there, it literaly feels like they're poking themselves directly in the back. Sensation 1 (from their finger) perfectly matched up with sensation 2 (the robot at their

  • Just because your brain is tickled, that does not mean there's no ghost behind you.

  • I wonder if this also explains why some people believe in an invisible sky daddy
  • The test subjects operated a robot arm with their finger. sometimes it would move in sync with them and poke them in the back. then they felt like they were poking themselves in the back. understandable. sometimes it was delayed. Then they felt like someone else was poking them in the back.

    How is that a breakdown of your self cohesion processing? Something you aren't really controlling is just poking you in the back! Sure, you gave the input, but i expect your cohesion times out after a couple millisecond

If you see a light in the sky moving so slowly that your brain interprets it as simultaneously stationary and moving, you may feel tha

    How can we be sure that Blanke's original electrical stimulation discovery in 2006 and the later the robot poking experiments didn't actually summon malevolent entities that then caused the spooky sensation (at a distance?) the participants experienced?

    On a more serious note, I'd like to see some follow-up interviews with the participants to rate how they felt after the experiment. Subjectively, did they feel like they had more "creepy" experiences following the experiment? I'd
