Attention, tasks, and lack of definitions (Score:2)
Not all tasks require attention. For example, I bet you have no problem listening to NPR in the morning while driving to work. The route is so overlearned that attention is not neccessary. You can listen intently and still get to work safetly.
Of course, it depends on what you mean by "task". For example, my visual system alone is extracting, in parallel, millions of features from the visual field--and all without the need for attention (some researchers call this 'pre-attentive', but IMHO that is lame). So, I can perform millions of tasks at once.
Having said that, there are definite instances in which we can seemingly perform only one task at a time. So whatever you mean by task, has to be well defined. Why are some tasks easy and some hard (and require attention)? Problem signal-to-noise ratio. The more overlearned or easier the task, the higher the signal. The lower the SNR, the more likely attention will be needed.

ADD allows a person to hyperfocus on most things are interested in. The problem is that if that person is put in a situration where there is more than one thing that requires concentration or they are not interested in a particular task, they tend to get "lost".
I personally have an appointment with a shrink to get diagnosed properly for ADD, however my mother has ADHD.. which is similar to ADD, but with hyperactivity as well as do various other people in my family.
No one quite understands how ADD works. Last I read it seemed to be more of the way you grow up rather than a genetic trait.

Asperger's is _very_ much like being single-tasked- but that's not to write it off as a deficit! It's another 'mode' of being, just like ADD (lotsa ADD advocates sounding off, I think that's pretty cool).
Someone earlier was talking about the mind's 'kernel' versus 'userland' and I thought that was a truly wonderful way of explaining what goes on with autism. In most people, the 'userland' is all over the place and can cover a lot of bases. In autistic people, the 'userland' might cover many or all of those bases, but it will do them one at a time and get stuck on them easily. It's like cooperative multitasking... _with_ the attendant advantages as well (yes, there are some if you constrain your requirements enough).
Temple Grandin, a well known and successful autistic adult, has explained it as having many deficits and liabilities but also having a 'Sun workstation' in one's head, and given the opportunity this can be a serious advantage. It's not simply being incapacitated for complex interactions like hanging out with 5 people all of whom have subtly different reactions to all the others (gah! How do you normals do this?), it's also having this weird 'black box' processor that normals don't have, and learning what it can do or helping it grow.
My own 'weird black box' has a lot to do with geometry and design (I was tested on a vocational test called the 'GATB' test and in one key part, a bit where you had to visualize what shape a flat figure could be folded into, I nailed a ten year high score on the test _and_ enjoyed the problems so much I wanted to keep doing them after the 5 minutes were up). I also have some of it devoted to English language and grammar, probably due to extensive reading
Driving? I haven't renewed my license, and it's been maybe five years now? I didn't get it _taken_ away from me, it just expired. Looking back, I got in too many accidents anyway so I'm not sure I _want_ to drive. Part of it certainly was drugs (I'm clean and sober at all times now and prefer that), but that's not the whole story- even when not high, I'd suffer from information overload or my brain would want to think about something else, and I hit other cars in fenderbenders. I'm happy not to drive now- it was yet another thing that I 'should' have been able to do, that _normal_ people are able to do, but reality kept tapping me on the shoulder and saying "yo! *crunch* that was a pickup truck's rear bumper, your beloved old Rabbit GTI is now toast while the truck wasn't even scratched!
However, a thought- I'm pretty good on a _bicycle_ because it requires more attention to keep it balanced and in the right place. Does anyone have opinions or experience regarding autistic/aspergers people on _motorcycles_? It only just occurred to me- it's possible that would be safer for all concerned, because a motorcycle would absolutely demand all one's attention, stick you out there in the wind with nothing between you and the road, and consequently travelling on a bike might easily result in total attention to the bike and the road and _no_ priority for interesting computer problems or whatever (my nemesis driving a comfortable automobile)

When you read accounts from someone who's experienced this 'can't-cope' or if you've had a taste of it yourself, then it's easy to get a little more specific about what is going on. It's not really so much that the center of personality is so _weak_- what's happening is basically that the sensory input is being set nice -256 or so! o_O
(For those who haven't gotten that far, 'nice' sets priority levels, and the high negative numbers set a process to very high priority, nearly locking out everything else- another telling similarity is that userland doesn't typically get to nice processes to such levels, only root gets to set negative numbers and users are normally restrained to setting processes to _lower_ values- i.e. 'forgetting' the process and having the computer pay less attention to it!)
With that understood, it should be easier to imagine what it's like having a sensory input set to unbearably high priority. I'm not Kanner-type autistic but I _have_ had experience with this- when I was a kid we had cats (I still identify with cats powerfully) and at times they had fleas. I developed a horror of having fleas in my bed biting me when I had to sleep- and I'd end up unable to sleep whether or not there were any fleas, because _touch_ would become so intolerably acute for me that I would be feeling individual thread-ends or grains of sand, all over, with the intensity of flea bites or crawling insects (normally a much more intrusive input!)

I've also seen my mom yelling at the top of her voice at my sister and my sister is basically paying no attention to her because she is so caught up in what she is doing and when you finally get action out of her by disciplining her it's just enough action to keep mom from disciplining her any more but even all through this yelling and whatever she still is focused on whatever she's fantasizing about.

Programming has been done since the 60s (Score:1)
The US government has known how to program people since at lease the 1960's. The perfect example is in the military. During WWII, some reports say as many as 80-90% of our service men did not fire their weapons in a combat situation. In order to overcome this the military did studies to find out why. They came to the conclusion that there was a resistance to kill other people hard wired into the human mind. What they did was train men to act automatically instead of thinking about it. The act of firing a rifle at an enemy soldier's head can't be delayed by thought. To this day the military forces of countries around the world are trained using the information collected by that research.
What can be used to overcome the resistance to kill is a trained response to a stimulus. You see the outline of an enemy soldier, you fire at it. Men are trained for weeks that when you see a foreign shape, you shoot it. No thought, no contemplation of right or wrong, just instant action. This has been done for over 30 years.
Granted this isn't low level programming, but if the point of programming is to determine behavior this is certainly a valid concern.

The brain is using tokens for it`s short- and midterm-memories. Most humans feature between four and eight, most have six tokens.
Therefore human concisness basicly comes down to the number of his tokens and their individual level of abstraction - sometimes people need two tokens for one thing where others only need one.

My own parents are impressive in their own mental ability but my mother stated last Christmas while cleaning the mess of opening presents that she liked it when she was smarter than I was. This leads to my major confusion, because if this is a recessive trait, then carriers would not necessarily be able to use it, however if it is dominant, it would figure that there would be a lot less stupid people in the world. And everyone who had the half/half combination would be able to utilize this trait.

Hot on the heels of a recent announcement that that human brain has rudimentary task switching capabilities, a local Linux advocacy group has created an initiative to port Linux to the Human brain.
Says the founder of the iniative, Niels Bohrman: "We feel this discover is a real breakthrough for Linux. The human brain has an installed base of over 5 billion. This could blow Windows out of the water."
The group feels that there are some technical challenges ahead of them but are positive and upbeat, steadfastly attempting to recruit from the most talented Kernel hackers the net has to offer. Says Borhman, "We feel that if we can get the right people working on this it will not be a problem. The basic science shows that the task switching abilties are there in the human brain, it should be an easy port."
When questioned about actual applications for the port the group was vague and evasive. "Don't ask a geek why" said one member defensively. Another member, who asked not have has his name revealed, expressed an unfullfilled wish to download porn directly to his brain.
The group has no timeframe for the Linux port to the Human brain but hopes to have a beta up on the net by the end of the year.
Attempts to reach Linus, the legendary creator of Linux, for comment on the iniativive were unsuccessful.
Alan Cox, a prominent Linux kernel hacker responded to news of the iniative with a short email saying that: "There might be some problems with virtual memory and a port to the Human brain, I'll have a patch out by the end of the week".

Most of your memories need cues so that you can remember them, these are older memories, that you think about less often, so they are further down in your subconscious (which is an abstract thing, not a concrete part of your brain, which I could point to and say, hey, there's your subconcious)
Memories that are "floating closer to the surface" are more easily remembered, with less cues.
I don't know about others, but sometimes when I am thinking, I drift off and think about other things, which in turn, makes me remember something I read, or saw, or something else someone did, anything. But if, I remembered every minute detail of everything, my thoughts would become jumbled, and I would never really return to my original train of thought, because just about anything would become a cue, since I remembered everything.

Brain Capabilities (Score:4)
If we were to have a memory like so many of you are describing, it would almost be impossible to function normally. You would remember many many useless things. For example: What time you got up yesterday to go to the bathroom, what color socks you wore 3 weeks ago, what you ate for dinner months ago, etc. Your brain would be filled with unimportant information like this, and it would be very cluttered. I believe there have been some cases where people did have this type of memory, and they were unable to function normally, because stupid little details like these would interfere with their normal train of thought. This is why you only remember the pretty important things. All of your sensory input is taken in, and then sent to your hippocampus, which it will stay for a short period of time. Your brain then decides wether or not to store it in memory. Anything which involves emotion has a much greater chance of being stored permanently, or at least as long as it's important. To recall these memories - especially old ones, you need some sort of cue, which brings it out, and puts it into conscious thinking. Audition (sense of smell) is one of the most powerful cues. (Like smelling cookies baking, and then remembering grandma's house)
And you don't usually forget things you'd like to, as someone pointed out - horrible war images. But other things, like car accidents, you may never remember, because if you were in the car accident, and you had any sort of blow to the head, at that point in time, information isn't being sent to the hippocampus, or if it's gotten there, it can't be encoded into memory, because at that point in time, a hard hit to the head would disrupt chemical activity, or neural pathways which allow this to happen.
And the other thing I'd like to point out, the fact that we only use 2% (or whatever %) of our brain is really a myth. We do use all of our brains. There is implicit and explicit memory. Say you got amnesia, and didn't remember anything - yet you still remembered how to walk and talk, and perform other simple tasks. This is part of your memory - which I believe is stored in your cortex (I don't quite remember) Most animals have very thin cortices (plural of cortex?) The larger your cortex, the more capacity you have. (The size of your cortex is determined by what kind of enviornment you were raised in. An experiment done with rats showed that a rat left in a cage by itself while it was young did not develop as thick a cortex as rats put in a cage with other rats, and rat toys for it to play with)

I know that models of how long term memory work are currently lacking. I believe the current models(aplasia and mammalian hippocampus model) predict long term memories of about a few hours based on the phosophorylation of receptor gated channels.
I agree that the mind probably manufactures a lot of the detail we seem to remember(I'm not sure whether this applies to those who have "photographic memory" since I'm not sure what having such a memory entails). I remember reading about psychological studies where people recalled an event from their childhood with a lot of detail despite the fact that it never happened. As I pointed out, using a computer model to explain the brain's function is not necessarily a good thing. I would definitely hesistate to say that the brain has X +/- Y bytes of storage.

I'm not too sure how much these things really affect us. Sure they have some influence but not the influence that you seem to attribute to them. These techniques seem more like nudging the mind in certain directions, they don't work all the time and they can't change the mind significantly.
However you have to agree that we don't have the ability to compel people to carry out complex tasks in a way we tell them to. I believe this is the sense the original poster used it in.
Actually alot of this seems to be a semantic problem. We use the word program in at least two different senses(cs, general usuage) without distinguishing between the two. Ills such as racism, sexism, ageism, etc, can all be traced to unwanted side effects of social programming, unless of course you believe those are fundamentally built into the human psyche.
I'm not sure that these problems are the result of social programming. People seem to have a inborn need to classify objects in the world around them in order to predict and understand the world around them. We put all objects that resemble each other in a certain category so that we can use our experience with one object in the category to explain other objects in the category will work. Although the way people classify each other seem to be social(race, class, etc.) it seems to happen universally. So, I think that this is probably a result of our need to classify.

Speed wise, signals travel along neurons at about 30 m/s. People have estimated that the depth of a typical path has to be a 100 neurons or less to get a reaction time of about half a second to a second that is necessary to carry out a conversation. However a typical neuron is connected to several tens or hundreds of thousands of other neurons so the brain is massively parallel.

Whether the brain is a computer is still a subject of considerable debate. The researchers seem to have located the region of the brain that allows people to jump back and forth between tasks. However, this does not mean that the brain handles this in the same way that computers do.
Even if the brain were to operate like neural networks (the cs/math versions not the bio ones) do, the possibility of programming it would be in doubt. Currently no one really understands how a trained neural network operates or how to actually program it directly aside from randomly assigning the connections a weight and then training it. And this is for relatively simple neural networks with maybe 5 layers, the brain is considerable more complex. It'll be a while before we fully understand it, let alone be able to consider programming it. We don't even know how long term memory is kept/created and the only models around only explain memories that last for a few hours.

What I believe he's talking about, in reference to LSD in connection with multithreading, is the fact that the human brain, on a non-trivial dose of LSD (or to a lesser extent, the tryptamines i.e. psilocybin, DMT) is an example of multithreading gone out of control.
Each external stimuli starts a new thread, but for the LSD victim, there is no kill command available. The result is much the same as it would be in a computer that continued to spawn processes with no ability to terminate them. As each process demands its clock cycles, each process runs slower and slower in real time. This is experienced by the LSD victim as 'time slowing down, dude'.
As the number of processes continues to increase, the victim is able to give consideration to more and more external stimuli, leading to the discovery of concepts never before entertained, such as 'wow, compact discs are so small they fit in your hand', and 'there is air on the moon, dude'.
Eventually, the brain is dragged to a halt, each of one trillion processes demanding it's share of the processing unit's time. No meaningful computation can be performed at this point. The LSD vicitm's mind interprets this phenomenon as 'white light dude. I'm seein' God'.
In the final stage, the ability to kill processes begins to reappear. One by one the threads are shut down, so that by 11 hours after the time the drug was administered, but two processes are left running.

Some psychologists believe that the process of selectively forgetting is a very important part of being able to see past the minute details of an experience and capture the larger meaning. The process of forgetting is not as simple as losing bits in RAM- how much you remember is based on how the memory was encoded in the first place, what cues caused you to retreive it, what about a particular event was important to you, and what related things have happened since. But even "unimportant" details that aren't stored very well in the first place deteriorate into vague impressions that still allow you to have some sense for what was there.
I can recommend a another book I'm reading right now called "Searching for Memory" by Daniel Schacter which gives a very readable description of the latest theories on memory function.

NAME
kill - terminate or signal a process
SYNOPSIS
kill [-signal_name] pid
kill [-signal_number] pid
kill [-l]
DESCRIPTION
The kill utility sends the TERM signal to the processes specified by the
pid operand(s).
Only the super-user may send signals to other users' processes.
The options are as follows:
-l List the signal names.
-signal_name
A symbolic signal name specifying the signal to be sent instead
of the default TERM. The -l option displays the signal names.
-signal_number
A non-negative decimal integer, specifying the signal to be sent
instead of the default TERM.
Some of the more commonly used signals:
-1 -1 (super-user broadcast to all processes, or user
broadcast to user's processes)
0 0 (sh(1) only, signals all members of process group)
2 INT (interrupt)
3 QUIT (quit)
6 ABRT (abort)
9 KILL (non-catchable, non-ignorable kill)
14 ALRM (alarm clock)
15 TERM (software termination signal)

LSD is interesting to this story because as a friend of mine once told me he was better able to multitask on it. All his college work was positioned in windows of information in front of him as he sat on a beach. So yes a drug will help you multitask but being able to manage all that information is about skill not speed. BSD was written on marijuana not crack. It's the differennce between seeing a bunch of windows in front of your face or seeing the ceiling melt into floor. One is a useful enhancement. The other depending on how you look at it is entertainment.
Consider trying to write an 8-part jazz piece with all parts going in all directions. It's funny. The whole concept of paying attention excludes the ability to multitask. Paying attention by definition means singling out parts which makes mutitasking impossible because you're constantly trying to listen and block each part out at the same time.
The same goes for deep hack mode. You've finally managed to convince the rest of your body not to sneeze, fart, or in any way disturb you while you work.

Task Processor (Score:4)
What this sounds like, OTOH, is the ability to use the *same* part of the brain for multiple tasks. This would be an extraordinary system, having to store a *lot* of information about the current state of the brain, and then be able to retrieve it for switching. (There seems to be some overlap with memory here, too...) In an extreme case, it may actually be holding copies, albiet probably simplified, of whatever networks were being switched. In computing terms, this thing could not only be a task switcher, but a swapper as well, actually changing tasks by swapping the activation patterns in and out of networks.
Speculating a bit, this system would also be a convenient way around nature's standard approach to multiple tasks, which is to evolve parallel systems. When behavior became sufficiently complex, it didn't make any sense to keep parallelizing for everything, so the switcher evolved as a 'quick-fix' that allowed the organisms to multitask new behavior before the better performing dedicated systems could be developed.
Still speculating, it no doubt takes short cuts, which could explain why people are so poor at switching. (For one thing, it may not attempt to 'force' the switch. The current task, or a monitor, would have to request that the older one be swapped in--this would not only be necessary for the current task to be completed, but would explain why people get side-tracked; they 'forget' to swap the primary task back in.)
As for a possible relationship to attention, I doubt it. Attention is a fairly old function, much older than cortex this region is part of, and isn't really switched, though the switcher may be *used* by the attention-function. (IIRC, the thalamus is believed to be the primary 'seat' of attention, which makes it *much* older and considerably more universal.)

But my point is the following: from the localization of the brain's coordinating area it cannot be inferred that -as it was afirmed in the original post- the human brain is the most powerful computing device in the Universe.

Now, this leads us to other question: will the development of Artificial Neural Networks lead to the production of such machines that exceed those of the human in what regards paralell processing, learning, vision and speech recognition/synthesis? I don't know. But 50 years ago who would know that a Von Neumann machine would play chess ABOVE grandmaster status?
