"Ghosts created by scientists in 'disturbing' lab experiment
Scientists in Switzerland have shown that ghosts are probably just an illusion created by the mind when it momentarily loses track of the body’s location."
COMMENT: OR WHEN THERE IS A "GHOST PRODUCING ROBOT" IN THE ROOM WITH GHOST-PRODUCING PSYCHOLOGISTS!
"Ghostly apparitions and hauntings have pervaded folklore and legend for thousands of years, but now scientists have shown that they are just a figment of the imagination."
COMMENT: Well, what they have shown, at best, is that such experiences can be reproduced in a lab with an elaborate mechanical device that creates an illusion. Somehow, I do not think that such devices are present when under otherwise normal circumstances, "ghosts" are reported.
"Artificial ‘spectres’ were conjured up by an experiment which proved so disconcerting for participants that two begged for it to stop."
COMMENT: WAS THIS A HAUNTED HOUSE EXPERIMENT ON HALLOWEEN?
"Scientists have long suspected that ghosts are an illusion created by the mind. Patients who suffer from neurological or psychiatric conditions often report ‘strange presences.’"
COMMENT: Correct. And what is REALLY interesting is that normal people, non-pathological, also report such "strange presences." NO PATHOLOGY, AND NO PSYCHOLOGICAL TRICKS, NECESSARY.
"And people experiencing extreme physical or emotional pain often claim to have seen ghostly outlines or felt that departed loved ones were back in the room with them.:
COMMENT: And what is really interesting is that people under no such extreme physical or emotional pain often also claim to have seen ghostly outlines or felt that departed loved ones were back in the room with them.
"Now, however, scientists in Switzerland have shown that ghosts are probably just an illusion created by the mind when it momentarily loses track of the body’s location because of illness, exertion or stress."
COMMENT: They have shown no such thing. What they have shown is that they can create ghost illusions, not that all ghost experiences are illusions. What they have to show to establish this strong thesis is that such neurological conditions are both necessary and sufficient for such experiences to occur, and that they can occur spontaneously, such that "seeing ghosts" (i.e. vivid apparitions) can occur in normal contexts.
"They saw up to four phantoms positioned around them and believed that ghosts were touching their backs with invisible fingers."
COMMENT: The more illusory ghosts they can create, the more likely a "ghost experience" is illusory. I like that logic.
"Professor Olaf Blanke, from the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland, said: "Our experiment induced the sensation of a foreign presence in the laboratory for the first time.
COMMENT: Did thy call Ghostbusters?
“It shows that it can arise under normal conditions, simply through conflicting sensory-motor signals."
COMMENT: How so? It was in a lab with robots. This is not "under normal circumstances."
"This confirms that it is caused by an altered perception of their own bodies in the brain."
COMMENT: No. It confirms that illusions of ghosts can be created in the lab by manipulating the subjects' perceptions of their bodies. That is all it shows.
"To manifest their ghosts, the scientists set up a robot device that allowed volunteers to control the movements of a jointed mechanical arm with their index fingers."
COMMENT: Right. All haunted houses are equipped with such robots.
"The movements were relayed to another robot arm behind them which touched their backs."
COMMENT: Sorry, Two robots.
"When both the finger-pushing and back-touching occurred at the same time, it created the illusion that the volunteers were caressing their own backs."
COMMENT: Wow. WHere can I get one of those robots? I mean two of those?
"That felt weird enough to the blindfolded participants. But something a lot stranger happened when the back-touching was delayed and about 500 milliseconds out of sync with the finger movements. Suddenly the volunteers felt as if they were being watched, and touched, by one or more ghostly presences."
COMMENT: Hum. Maybe all persons reporting such "ghostly experiences" are blindfolded and in the presence of robots.
"At the same time, they had the disconcerting sensation of drifting backwards, towards the unseen hand."
COMMENT: Wow, now this is getting spooky.
"When questioned, several reported a strong feeling of invisible people being close to them. On average, they counted two, with up to four being reported."
COMMENT: So, two robots, a lab and a blindfold equal multiple ghosts. Sounds like mathematics. It must be right.
"Two of the 12 healthy participants were so disturbed by the experience that they asked the scientists to halt the experiment."
COMMENT: So, when they were disconnected, did the stress make them see more ghosts?
"Co-author Dr Giulio Rognini, also from the EPFL, said: "Our brain possesses several representations of our body in space."
COMMENT: O.K. . . . SO?
“Under normal conditions, it is able to assemble a unified self-perception of the self from these representations."
COMMENT: O.K. . . . SO?
“But when the system malfunctions because of disease - or, in this case, a robot - this can sometimes create a second representation of one's own body, which is no longer perceived as 'me' but as someone else, a 'presence'."
COMMENT: Right. Now if we check all reports of ghost sightings we will surely find that all such experiences were in the context of robots or disease. Check that out and report back.

Finally, the responses here are typical "band-wagon" thinking without taking the time to assess just what is being claimed and the evidence for it. If a "psychological study" agrees with your worldview, jump on it uncritically.
That is not to say that there are real ghosts, or that such studies are not helpful to understanding human illusions. But creating an illusion of ghosts does not mean that all ghosts are an illusion, any more than creating an illusion of an elephant means that all elephants are illusory.
