Can you just give us the title and author? It's hard to feel comfortable downloading stuff from a stranger, especially since others have used that method for nefarious purposes here in the past.

Yeah i havn't clicked but this seems like some form of tom foolery. I mean what are the chances we have a first time poster that isn't familiar with how to post information on the net, but has some ground breaking psi paper tucked away.

I can't speak for the JREF, but I think yes, provided the protocol gets cleaned up a bit to:
  • make positive results unamiguous
  • to clarify statistical power
  • to provide blinding of the evaluators as well as the subjects (double blinding, rather than just single blinding).

Hi again,

I completely understand your reluctance to access the site. The admonition about logging your IP address is to keep people I don't invite away from my FTP server. Every web site you connect to logs you IP address as a matter of course.

But again, I understand.

Here is the title and some info that may allow you to find it independently through a Google search:

The Journal of Alternative and Complimentary Medicine
Volume 11, Number 6, 2005, pp. 955-963

The Title is: "Replicable Functional Magnetic Resonance Imaging Evidence of Correlated Brain Signals Between Physically and Sensory Isolated Subjects"

The abstract follows:

"TODD L. RICHARDS, Ph.D.,1 LEILA KOZAK, M.S.,2 L. CLARK JOHNSON, Ph.D.,1
and LEANNA J. STANDISH, N.D., Ph.D.2

ABSTRACT

Objectives: Previous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) experiments have suggested that correlated neural signals may be detected in the brains of individuals who are physically and sensorily isolated from each other. Functional MRI and EEG methods were used in the present study in an attempt to replicate these findings.

Design/settings: Subjects were electrically and magnetically shielded because of the characteristic surroundings of the scanner room. During the experiment, the nonstimulated subject was placed in the scanner with sensory isolating goggles covering the subject’s eyes. The stimulated subject was placed 30 feet away and sat in front of a video monitor that presented an alternating schedule of six stimulus-on/stimulus-off conditions. The stimulus-on condition consisted of a flickering checkerboard pattern whereas the stimulus-off condition consisted of a static checkerboard. Stimulus-on/-off conditions were presented in the sequence on/off/on/off/on/off. The duration of these intervals was randomly assigned but consistently provided a total of 150 seconds of flicker and 150 seconds of static. Sessions were repeated twice to assess possible replication of the phenomenon.

Outcome measures: Changes in fMRI brain activation (relating to blood oxygenation) and EEG signals were measured in the nonstimulated subjects. Changes occurring during stimulus-on conditions were statistically compared to changes occurring during the stimulus-off conditions.

Results: Statistically significant changes in fMRI brain activation and EEG signals were observed when comparing the stimulus-on condition to the stimulus-off condition in nonstimulated subjects (p 0.001, corrected for multiple comparisons). For fMRI, these changes were observed in visual brain areas 18 and 19 (Brodmann areas). One of the subjects replicated the results.
Conclusions: These data replicate previous findings suggesting that correlated neural signals may be detected by fMRI and EEG in the brains of subjects who are physically and sensorily isolated from each other."


If there's anything I can do to put you at ease regarding downloading the PDF, let me know. In any case, I think I've provided enough information for you to find it through a Google search.

BTW, I'm a moderator at another web forum. In our Philosophy forum I'm known as an ardent skeptic and have been there for going on a decade. The thread where this study was made known to me is titled "Why the JREF million dollars remain unclaimed." You can find it here and my posts there are under the same screen name I use here: Diploid

www . shroomery . org/forums/showflat.php/Number/11950520/fpart/all/vc/1

The above is a message board.

Thanks again for any input.

Today has to be weird message day, i got a lengthy weird page about spamming that started with " our software reckons..." or something of that nature.

And unless my browser is posting multiple copies of anything i post ( accidentally of course) i don't recall spamming.

Question

Good call JoeTheJuggler, that's exactly where it's from.

The title of that journal gives me pause too. I mean, they probably publish homeopathy BS too. But even a fool can be correct and the study's validity is independent of where it was published.

If the data published is accurate (I doubt it is, but I keep an open mind) and if it can be replicated with a larger sample size, it beats chance by a wide margin, no?

I logged in from a proxy.

The original poster is probably just unable to post live links. The link went to: [Replicable Functional Magnetic Resonance Imaging Evidence of Correlated Brain Signals Between Physically and Sensory Isolated Subjects] published in The Journal of Alternative and Complementary Medicine v11, no 6, 2005 pp955-963.

Dean radin discusses an Indian attempt to replicate in 2008: [Telepathy on the brain] He states that as of that writing there were four fMRI studies completed, of which 3 show some sort of effect. He doesn't cite them, though.

Right. The forum prohibits posting live links until the member has >15 posts. To prevent spam, no doubt.

On the other hand, this study has nothing to do with Alternative and Complementary medicine, and if valid, should be published in a much higher impact journal. That it has been published in the 'wrong' place makes one suspect that they were unable to get it published in the 'right' place.

It's typical parapsychology stuff - get messy data, keep dividing it into groups until you find two whose difference is "statistically significant", attribute that difference to psi.

I'm not too happy with the protocol in the paper, but the principle of testing for fMRI results in the reciever could be assumed to be unconscious reception. I'd like to build a protocol that produces unambiguous and binary outcomes, has better blinding, and is double-blinded to blind the experimenters.

Generally psi protocols just ask the receiver if they got the image (eg: Ganzfeld), but this variation is intended to detect unconscious reception. (How low the bar has moved, eh?)

Ahaha... so true!

ETA: In fairness to the study, the positive results were generated by algorithmic analysis of the fMRI, not by interpretation by a radiologist, so from that point of view, it was double blinded. The machine computing the results is blind by default. They'd have to be outright cheating to skew the results.

On the other hand, wasn't that what the Princeton Engineering Anomalies Research people end up doing when they couldn't produce results fairly?

Well, the CAM people are certainly looking for anything that will shore up intention to heal modalities. You know: the healing techniques that involve the word 'quantum.' Dean Radin's interpretation of the fMRI studies is that it's evidence of quantum entanglement of intention and target. So, there's your link.

Here's Adam Dreamhealer invoking Edgar Mitchell and quantum entanglement to explain his ability to heal at a distance: [Adam Interview and Article Never printed]

Quantum entanglement, healthfraud and UFOs. A skeptical trifecta.

Assuming the factors they chose to use were determined in advance. What we have to be cautious about is whether they ran, say, 400 retrospective analyses and settled on publishing the one that showed significance.

Yes, Ray Hyman really took a chance with that one and was ultimately vindicated. I'm personally more hesitant and prefer to wait for actual evidence of fraud before specualting openly.

I see nothing in the paper about any attempt to measure or control of high frequency audio leakage from the computer monitor. I could not find a reference to such from Google but I have personally heard such a "whistle" that varied with the pattern displayed on the monitor.

Hey, remember, even a result of .001 significance will randomly occur in 1 study out of 1000 (by definition). I say wait for another study to reproduce the same anomalous result.

The outcome to consider significant wasn't chosen blindly. They simply tested all outcomes and picked a few (the outcomes weren't the same between the two experiments) as significant after the analysis was done.

The receiver in the fMRI machine was wearing headphones.

But the authors do admit that sensory leakage from incompletely opaque eye or ear coverings could be worth looking at when replicating.

Exclamation

You know: the healing techniques that involve the word 'quantum.'

Yep. Quantum Entanglement has become such a buzzword and it's used incorrectly so often it's really discouraging. The amount of layperson misunderstanding of what it means is rivaled only by the misunderstanding of superluminal effects that don't convey information and so don't violate causality as so often stated by people who read Popular Mechanics and fancy themselves physicists.

Regarding "high frequency audio leakage from the computer monitor". I hadn't even thought of that. Such leakage could well be below the subjects' conscious detection threshold yet still be strong enough to be detected by the cochlea and influence the fMRI.

Correction: I though I'd read that the headphones were playing a sound to mask room noise. On second reading it looks like they were just passive attenuators so possible sound leakage from the computer monitor was controlled for.

This is also the sort of thing that really should have a good magician on hand to ferret out intentional cheating.

The two subjects have known each other and have been doing this demonstration (I really want to call it a "trick") for years--according to the article.

Also, from reading the article, I still don't understand how the thing was "random". They followed an on-off-on-off pattern for each trial, and the total value of ons was the same number of seconds throughout. If their randomizer wasn't random, I could see a simple, pre-arranged pattern of a certain number of counts between each change.

Oh yeah. One need only mention 'quantum' (no need to use it correctly) and one gets a free pass to a peer-reviewed journal.

Radin did admit (during the Q and A after a lecture he gave at some university) that his reference to "quantum entanglement" was metaphorical only. Of course, he was facing an obviously knowledgeable audience in that case. Stuff he writes for other audiences looks like he's trying to get away with claiming it as a real example.

The abstract does say that they corrected for multiple comparisons, though.

Oh great.

I remember someone describing this being done at the Cayce House (or Museum or whatever it's called). They did a really simple test of all the people in the tour group for ESP. As expected, they got a nice normal curve centered on the number you'd get right/wrong due to chance alone. They told those who scored more than a standard deviation above the mean that they obviously have ESP.

Link to the journal abstract directly, which has been posted above.

Not speaking to the quality of the study but the authors are at least associated with legit universities. Bastyr keeps trying but they are not above stretching conclusions in their attempt to legitimize sCAM.

Getting to the quality of the study, it sounds like they did this with only one or two people and

One of the subjects replicated the results.
That's very UNimpressive.

Two subjects who have known each other for years and have been performing this trick demonstration elsewhere.

The two subjects have known each other and have been doing this demonstration (I really want to call it a "trick") for years--according to the article.

Also, from reading the article, I still don't understand how the thing was "random". They followed an on-off-on-off pattern for each trial, and the total value of ons was the same number of seconds throughout. If their randomizer wasn't random, I could see a simple, pre-arranged pattern of a certain number of counts between each change.
My interpretation was that the on/off durations were themselves random. The attempt was to see if the fMRI change coincided the start times of the stimulus blocks.

Ahaha... so true!
Don't you still think it would be an interesting phenomenon if it were rigorously proven to exist?

On the other hand, wasn't that what the Princeton Engineering Anomalies Research people end up doing when they couldn't produce results fairly?
Is there anything to suggest it is fabbed? Is there another flaw in the experiment, one which may not be "obvious"?

Yes, that's what the article says, but it doesn't specify how they were made "random". And, IIRC it said each trial was to follow the pattern on, off, on, off, on, off, within a set time limit such that the on and off totals were of equal duration. (I point this out because it doesn't seem that tossing a coin or rolling a die would easily provide a way of randomizing the durations, so I think it's a question that should have been answered in the paper.)

Since this field is rife with fraud, poor methodology and easily duped investigators, I wouldn't be surprised if their idea of "random" wasn't to leave it up to the sender who could easily have made a plan with the receiver (they were long-time friends).

So the sender uses a clock or whatever is being used to keep track of the on and off period, while the sender just counts "one mississippi two mississippi" and does something else different that might show up on the fMRI (like the old polygraph trick of jabbing yourself with a concealed thumbtack).

This is also part of why a shyness effect or goat effect is evident. Regression to the mean.

Put these outliers back into the test, and best bets are they'll perform average.

'cause that's random chance for ya.
