Anybody come across this study before?

[shoredivr]

Mods if this isn't an appropriate forum for this, please move it.

On another board I came across this study regarding the effects of narcosis and learned responses Omni Divers Underwater Services, L.L.C., Ice Diving, Enriched Air Nitrox Instruction, Search and Recovery, Scuba Diving Instruction, DAN Oxygen Training and Dive Travel. One conclusion from it is that negative programming can lead to negative responses at depth.

Can anyone comment on how rigorous the study is? I would think it would pass muster from the names attached. I've seen it referenced before, just not seen the entire study.

"The obvious conclusions include a subjective validation..."

Obviously subjective

"If we teach our children that all dogs will bite, we can safely assume that when presented with a specimen even as lowly as a toy poodle (which should probably be shot on sight anyway), we can expect a high fear index."

I don't feel this is a necessarily good analogy, and when you include a statement in a supposed research project that an animal needs to be shot because of its breed???

I don't see it as good research...I don't see it...based on what a true research study is...as research at all. At best a generalization that you can come to in any problem solving section of a deep dive class.

I think it makes sence;

If a person is quickly educated, "You can die, if you go scuba diving." but told nothing else, that person will be apprehensive at best.

If a person is educated beyond that point, taught the ins and outs, regarding how he/she can die while diving, and the percautions, that person will fear it less.

Less fear going into the water, less stress. Less stress at 200fsw, less likely to become Narc'd.

Wonder what a cross between a poodle and an English bulldog would look like?

I have not seen the full study either but I would expect that if it presented in full anywhere, one might want to check the old NAUI Underwater Education symposia. (Sam? Phil? you guys have the set handy?)

It is referenced here with a slightly more scientific explanation for the training phenomena they presented.

Gene,
I only have the minutes of the IQs I was involved in as a speaker etc.
Do not recall this as being a subject at IQs I attended as a spectator.

Maybe there really isn't a dumb question? English Boodle, English Boodles, English Bulldog Poodle Hybrid

Appropriateness is another matter...??

It sounds as though the study had very small numbers, but the methodology as described sounds pretty reasonable. All study participants KNEW they were going to depths where narcosis would be present, and that they were being evaluated for the severity of symptoms. If they didn't know what the independent variable was, the study should have been reasonably good (again, but with very small numbers).

I wouldn't be at all surprised at the findings that people are highly suggestible into more severe symptoms. That's why I never tell patients, "This is going to hurt." Studies show that if you do that, it will.

The question was how rigorous was this test? Hard to tell without more info such as the extent to which subjects were totally unaware of what was going on. As TS&M said, the number of subjects per group is extremely small. It is impossible to realistically draw conclusions from such small sample sizes. Also, the so-called "placebo effect" accounts for about 30-40% of the results in typical studies like this.

Thanks for the reference, Gene.
