View Full Version : Sensory deprivation.

Interestingly, I was watching a BBC program last night and it was about isolation experiments in people. What they did was take a dozen people and isolate/bombard them from all external stimulus for 48 hours.

One half of the group had googles on that just blurred their vision, lights on all the time, and headphones with white noise. So, lots of constant stimulus.

The other half had a complete absence - dark, no sound.

They all performed pre and post tests, which tested things like impulsiveness, memory, etc. It was more of a general test rather than targeted at any psychological testing.

The most amazing thing was that after the testing all the subjects 'became' ADD. They didn't say this in the documentary at all, but it was so clear as they said each issue. Lack of concentration, poor working memory, poor compulsion control. It was as though both the lack of stimulus and over-abundance of stimulus was causing these issues - not the other way around.

So, consequently, with us normal ADDers, (ha ha), it is the stimulation control that causes these issues, and not the other way around. This changes my understanding of ADD slightly, (or rather I've forgotten it and I'm just refreshing it), and the implications. That is: we need the right amount of stimulus for our brains, otherwise our brains 'shutdown'. Too much or too little is no good. As ADDers - we lack the control mechanism, (or valve), over the sensory input.

ADHD - just waaaay too much input.
ADD - not enough.

Mmmmm, I seem to remember someone talking about this before on ADD, but can't find their post.

I like the valve control or faucet analogy, MMijahe. It's not a mere matter of replacing a worn washer.

It's the whole regulation of the hot and cold, the "flow" of water, and how each individual mixes all of that together in relation to who is affected by the shower.

What's the right temperature, volume, pressure, "flow" consistency and pattern? Complex stuff. :cool:

How much did the participants sleep in this 48-hour study?

There was a mix. One person slept pretty much the whole time. The others dropped into a 4 hour cycle. They all fell a sleep pretty much straight away except for one other person who stayed awake purposefully and meditated.

I'll check around and see if I can dig it up from somewhere.


OK, found a reference to it here
http://www.bbc.co.uk/sn/tvradio/programmes/horizon/broadband/tx/isolation/

I'll see if I can dig up the video.

Well, I think we can be certain of one thing, and that's that the individuals did not have ADHD beforehand. One, such would not last 48 hours in those conditions without a locked door. Two, they definitely would not have done so well on those initial tests (well, I suppose that it is possible, but I don't think the idea of sitting in the dark for 48 hours would have me all that excited).

So, you managed to watch it? Interesting isn't it?

Their hallucinating that they experienced was interesting.

So, the lack of stimuli or overabundance of stimuli caused a chemical imbalance in their brain. The onflow effects caused an ADD-like attention/impulsive issue, and other 'executive dysfunction' issues.

Yes, I did catch parts of it while researching vehicular theft deterrent systems (for no good reason in particular).

I think I caught part of the hallucinations (or perhaps, sensory distortions). It's really difficult to be a judge though as to the validity of this experiment. I know that I'd be in a rush to get out of there after such an experience, and that alone would seem like it would trigger an increase in impulsiveness. I'm thinking that they probably should have had a control group for this (putting someone in a room for 48-hours, but with normal lighting conditions. Not that I don't believe that it has any effect, but it's hard to filter out some of the variables here.

Not getting distracted again? :) I like the anti-theft system in Robocop, although would get a bit smelly.

Yes, it does seem to be a popular test, (popular - as in water down for the general population). There wasn't any baselining at all. I assume they did psych tests on them beforehand, but they didn't say that in the documentary. They also didn't put the subjects in the same room with the lights on for the same period - just to see if it was something else.

(Whether that was by accident or not - dunno.However, they did backup some of the tests that were conducted previously.) The psych did seem to be aware of what results he should be getting out of it - so maybe the results were also tainted.

thanks for this -
real interesting.

My wife mentioned that she'd read about kids who were deprived of stimulation in some repressive regime -
reacting by self mutilating.

Neural stimulation not negotiable -
- however kids don't have developed minds.

Boredom (insufficient neural stimulation) in aduts
->
bored at work
(as your study shows)
has
alongside the mechanism by which first mind arose

lead to the capacity to be 'driven' -
- even when the external environment fails to offer
(our workplace)

So -
as we were hibernating -
the imaginary realm (dreamscape began)

the dreamscape entered the 'real world'
as ADD daydream

- and the daydream is simply the capacity to fire off theta and to resonate off one another and the planet
- to float our boats in the absence of exogenous stimulus

So - the workplace bores us rigid

- if we've a developed mind containing much data -
we dream -
we float our own boats through the happiness of our cogs being turned by the planet.

Resonation.

In younger kids -
without developed mind

neural stimulation is based on the external world -
- younger kids without appropriate neural stimulation truly suffer -
hence self-mutilation
(the drive for neural stimulation eating them alive).

It's very hard to lift out of this happy place

form filling
entry into any non-intuitive mindscape results in having to divert one's mental capacity into these trivial money making tasks
which ADDers cannot do
because ADDers have surpassed the need for money
and the gains from money (from a personal perspective)
are much less than the gains (personal reward) which the individual experiences in ADD space.

Boring tasks are trivial -
however more importantly -
andy task which takes us out of multithreaded nonADD space is less fulfilling -
and the happiness of dreaming -
is an energetically favourable state -
which becomes more favourable with development of mind
and which actually prevents engagement of the mind in lesser activities.

From another perspective -

we've finished a race - and want to celebrate -
however the nature of money is that we need re-train when our company goes out of business -
- or technology dies.

It's not right -
- money lies at the core of our problems -

- we can evolve to happiness if only we allow ourselves to
- and once there - need nothing other than to be left alone.

The problem then -
- that money forces those who have a mind resonating out of happy space into painful
unfulfilling nonlinear space.

ADD is the waking meditation
8 Hz with eyes open

people communicate at 8 Hz because of the carrier effect of the principal mode of schumann
also at 8 Hz
theta EEG is at 8 Hz
transition sleep/wake there too at 8 Hz
meditation at 8 Hz
Access to creativity too at 8 Hz

finally
and most importantly

man's central dopaminergic circuit has recently evolved down to 8 hz -
meaning that the evidence is far too strong

this stuff is pretty unequivocal.
