'Just Sleep On It' Solves Tricky Problems?

An anonymous reader writes "CBC news reports that the effectiveness of 'sleeping on it' when faced with a difficult task may have more than just anecdotal roots. 66 students were trained to perform a calculation on an eight digit number using two simple rules which would take seven steps to complete. A different method existed to perform the same calculation 'almost instantly', but was not shown to the students. After eight hours, where half the students were allowed to sleep and the other half remained awake, 60% of the rested and 22% of the wakeful students discovered the more efficient method."

If you are consciously thinking about a problem, you can also direct your attention to different aspects of it, to a certain extent. Of course, if you don't yet know the answer to the problem, you don't know the best route to the answer, and therefore your conscious direction is as likely to be bad as good (in fact, your mind's automatic direction is likely to be better, because that's what's been trained to solve that sort of problem; you can tie your shoes by a motor program, but you probably can't figure it out easily consciously without "doing it and watching what you're doing").

If I came up with the surprising solution immediately, then it might be suboptimal if an obvious solution could also do the trick: a case of too clever for your own good.

      1. It is very well established that people do not think in their native language, but rather, we think in what psychologists call "mentalese," and then translate that into words when we need to speak or write, or, to carry on an internal conversation with ourselves. Note that an internal monologue is not thought itself, but an after the fact verbalization of conceptual cognitive processes which take place in mentalese. A trivial example is mentally rotating a complex three dimensional solid in your mind's eye. There are no words used here at all - just mental images, though one can, of course, translate these images into words for use in conversation, or for an internal monologue about the process.

      2. Posters to this topic seem often to talk about the conscious mind, and the unconscious mind. It is very well established that the overwhelming majority of cognitive processing in the human brain takes place below the threshold of consciousness. Thus, we are more more properly characterized as a largely unconscious cognitive process with some (few) conscious aspects.

      Some psychologists and neurologists believe that even the tiny fraction of cognition that is presented to consciousness, is presented to conscious awareness after the fact, often giving the false impression that it was a conscious choice that led to a particular action, when, in fact, the choice happened before we became aware of "making" it.

      I can do that, and have done so all my life (going on 49 now).

The act of setting the alarm apparently is sufficient (tho not 100% required) to set my brain to wake at that time.

      I can also set myself to wake on some particular event, such as "2nd jet of the morning" (when I lived next to an airport) or when WinAmp gets to a certain title in my playlist (I regularly do that with afternoon naps).

      Note: I'm a VERY light sleeper, and I don't move in my sleep at all (if I go to sleep with my thumb up my nose, that's exactly the position I'll wake up in -- in the morning my bed always looks like no one uses it); I wake up to turn over. I tend to be fairly aware of my dreams, and dream in cycles and clumps rather than as a "regular nightly thing".

      My sleep cycle is roughly 2.5 hours, and while I can get by on two cycles per day, three is better. When I'm getting enough sleep, I'm a morning person, up with the sun (and less likely to need an afternoon nap). If I'm short on sleep, I'm also more likely to stay up late and sleep late. I've noticed that a lot of "night owls" are like that -- they really aren't night people, and aren't very functional at such hours; seems that in fact they're just chronically short on sleep.

It can be any fiction you're interested in (reworking a novel or TV show is fine, it need not be original, but it must NOT be something work-related). Every night, retell the same story from the beginning, tweaking details as you go. At first it will take a while to go to sleep as the story is still fresh, but after you've done it enough, all you have to do is start the story, the brain goes "booooooring!" and you're asleep before you get the story properly rolling.

Think about it a lot during the day to get the network good and excited, then take your constrained rational thought process off line.

The problem is that if the solution isn't down one of the paths you keep thinking along, you're not going to find it that way. Pulling the logic controller off the job (whether by sleep, running, music, whatever) while the neurons related to the problem are still in a heavily excited state (from all the active processing you've been doing) gives the neural net a chance to try some less obvious pathways.

    Take an 8-digit string formed from the numbers 1, 4, and 9. A series of two-digit comparisons is done. The result of the comparison is the same digit if they are the same, or the "missing" digit if they are different. That is, 1 1 -> 1, while 1 4 -> 9.

    Start by comparing the first two digits, and from then on, compare your current result with the next digit in the string. Their example is 11449494, which leads to the results 1, 9, 1, 4, 4, 1, 9. The last result is the final answer.

    The trick is that the original strings were "generated in such a way that the ... second [result] coincided with the final solution." People who found this trick were deemed to have gained insight into the pattern.

    I think the study is bogus because of this. Sure, some people will notice the pattern, but careful people might choose to carry out the full calculation anyway, just to make sure. Any given string could follow the pattern or not. What they're demonstrating is how easily people can be tricked into finding patterns that may or may not be there. This kind of learning leads to racial profiling --- the result of the easy observation (race) implies the result of the more difficult one (criminality).

    Chapter 6
    'Principia Mathematica'
    In July 1900, there was an International Congress of Philosophy in Paris in connection with the Exhibition of that year. Whitehead [eventual coauthor of Principia Mathematica] and I decided to go to this Congress, and I accepted an Invitation to read a paper at it. Our arrival in Paris was signalized by a somewhat ferocious encounter with the eminent mathematician Borel. Carey Thomas had asked Alys to bring from England twelve empty trunks which she had left behind. Borel had asked the Whiteheads to bring his niece, who had a teaching post in England. There was a great crowd at the Gare du Nord, and we had only one luggage ticket for the whole party. Borel's niece's luggage turned up at once, our luggage turned up fairly soon, but of Carey's empty trunks only eleven appeared. While we were waiting for the twelfth, Borel lost patience, snatched the luggage ticket out of my hands, and went off with his niece and her one valise, leaving us unable to claim either Carey's trunks or our personal baggage. Whitehead and I seized the pieces one at a time, and used them as battering-rams to penetrate through the ring of officials. So surprised were they that the manoeuvre was successful.
    The congress was a turning point in my intellectual life, because I there met Peano. I already knew him by name and had seen some of his work, but had not taken the trouble to master his notation. In discussions at the Congress I observed that he was always more precise than anyone else, and that he invariably got the better of any argument upon which he embarked. As the days went by, I decided that this must be owing to his mathematical logic. I therefore got him to give me all his works, and as soon as the Congress was over I retired to Fernhurst to study quietly every word written by him and his disciples. It became clear to me that his notation afforded an instrument of logical analysis such as I had been seeking for years, and that by studying him I was acquiring a new and powerful technique for the work that I had long wanted to do. By the end of August I had become completely familiar with all the work of his school. I spent September in extending his methods to the logic of relations. It seems to me in retrospect that, through that month, every day was warm and sunny. The Whiteheads stayed with us at Fernhurst, and I explained my new ideas to him. Every evening the discussion ended with some difficulty, and every morning I found that the difficulty of the previous evening had solved itself while I slept. The time was one of intellectual intoxication. My sensations resembled those one has after climbing a mountain in a mist, when, on reaching the summit, the mist suddenly clears, and the country becomes visible for forty miles in every direction. For years I had been endeavoring to analyse the fundamental notions of mathematics, such as order and cardinal numbers. Suddenly, in the space of a few weeks, I discovered what appeared to be definitive answers to the problems which had baffled me for years. And in the course of discovering these answers, I was introducing a new mathematical technique, by which regions formerly abandoned to the vaguenesses of philosophers were conquered for the precision of exact formulae. Intellectually, the month of September 1900 was the highest point of my life. I went about saying to myself that now at last I had done something worth doing, and I had the feeling that I must be careful not to be run over in the street before I had written it down.

It could have been a semiconscious exploration of the search space, the simple refreshment of a short rest, some distance from the problem that allowed a fresh perspective, or even a placebo. We did not have the resources (esp. time!) to study this effect scientifically. But it did help, and that was our main priority at the time. There may also be other ways to get these benefits; I've heard similar things about meditation, but that's not from personal experience.

    Some cautions: if not practiced at short sleeps, or if drastically sleep-deprived, that short sleep could turn into 13 hours; sudden waking seemed to prevent any benefit, so only set an alarm later than the expected waking time; waking can involve a need to scribble down ideas suddenly, so keep a pencil and paper nearby unless you want to re-enact a scene from "Memento".

    It is my belief that the human brain is a magnificent pattern detection machine. That is how we, as a species, have evolved to be successful, because our brain can make linear sense out of an otherwise chaotic environment.

    But when we learn language, and theories, and skills and stories, our brain gets filled up with all this information which, while extremely useful in obvious ways, also acts to create filters in our minds. The more we learn, the more we think we know, and the more we distrust anything our brain picks up on that we have not consciously learned. It's why children can often be cuttingly insightful and have potential far above what most adults credit them -- they have not yet learned that they are not supposed to understand things yet.

    Our brains pick up on many things in this world that, as we grow older and are told things by other people, we learn to ignore. Deja vu... first impressions of other people (including love at first sight)... ghosts... premonitions, or just having a "feeling" about the way something will turn out... resolving complex problems when not even thinking about it... They are all linked, yet we are trained to discard some of them as superstition or bad gas.

    We figure things out when we sleep or are otherwise distracted because our conscious mind drops the filters and lets the real hardcore pattern detection machine, our unconscious mind, which has not been and cannot be corrupted by our attempts to consciously control it, send out its results.

    For the next week, try really paying attention to your feelings and unexplainable impressions of the events and people in your everyday life, including yourself. (For example, you often know in your gut that you're doing something wrong, but consciously you think it's what you're supposed to do so you will create rational excuses for it; it's how people end up looking stupid on Dr. Phil without having any clue about it beforehand.) You will find that you are a much more intuitive, insightful, and powerful person than you realized, if only you can learn to trust yourself over what you've been taught to believe. It's like tapping into a part of your awareness that you didn't even realize was there.

      For example, I once read an article (linked from here I believe) where a very young autistic child drew a picture of a horse, which was remarkable for her age. The idea is that since he/she did not have the label/classification system in place in her mind to filter things into, she simply drew what she saw.

      You fail to understand one little fact, though. Trusting feelings could be a good indication that the "pattern machine" has supplied an output, but it could also be a false positive based on conditioning. This is why people refer to childrens' minds as impressionable; those impressions are truly unbiased, and the subconscious mind burns these paths the most deeply.

      Once those paths are burned, all other paths are burned in relation to these; similar in the way that the Internet is based on branches out from several major backbones; if something takes out the backbones, huge parts of the Internet will be taken out until the backbone is back in operation.

      The same applies to the mind; the initial experiences, the ones that are had by children, are deep in the mind, which actually are programmed into the subconscious mind; that mind will match all the person's knowledge with the information that was taken in, and form their solution from the discrepancies.

      In cases of mathematics, there's no wiggle room, so naturally, the mind will be more likely to come to a correct conclusion. However, this doesn't mean that sleeping on more subjective matters is going to yield any more than a possible solution flavored by one's own opinions.

      Another point, however, the same applies for the above-mentioned attitude; there are a lot of people out there, like myself, who, as they learn more, they realize there's far more out there to know... in short, as they get smarter, the more they realize just how blind they were to the vastness of the topic in which they previously believed themselves close to discovering.

      An example:

      Once upon a time, doctors were doctors; physicians who knew medical procedures for a large number of ills; the field was limited, and thus, easy enough for one man to practice.

      However, as time marched on, the field grew, and grew, and grew; people began to realize that the topic was much, much vaster than previously believed, and thus the age of specialization began; each person focused on a specific part of the body, be it the epidermal layer, the pancreas, eyes, feet, or the nervous system, and focused only on that.

      But I digress.

      The point here is that the mind is limited, even in the sub- and unconscious minds by the past experiences and opinions that make up a person's emotional makeup; even sleeping on a topic isn't going to make a person change their preconceived notions, unless those notions are recently-acquired. Otherwise, they will usually suffer a catastrophic loss of confidence, sometimes to the point of losing their grip on reality.

      After all, what you grew up with defines your perception of reality, and when something so deeply defined is disrupted, even your subconscious mind will doubt the validity of the rest of your deep definitions. ...or maybe I am just spouting nonsense, who knows?

    OTOH, my concious mind keeps a stream of thought going at all times, so maybe I am "pestering it constantly" when awake, and I use sleep to give my subconcious the quiet it needs to work. That would agree with your: If you're asleep, that part of your mind has nothing better to do than work on whatever incomplete tasks it has from when you were awake. I have great difficulty with activities that require blanking the mind, such as doing meditation or watching TV. Those activities slow my mind until I act almost like a normal person. This fits in your theory.

    I am not certain my concious mind is actively involved when writing code. I often refer to it as "flowing from my fingertips." I can carry conversations while my fingers are typing. I regularly multi-task anyway, but I do not even feel involved in the programming process. I rarely "go to the whiteboard." It helps that my applications rarely need other programmers, and when they are involved, their portions are defined by APIs. Either those APIs are part of the specs I am given, or we do not write those APIs until we can see the code (written by my subconcious) and decide how the other parts should interface.

Of course they only [want to] pay me based on the number of hours my concious mind is engaged with their work.

I must write books to make it happy. If I want to go running, I need to bring a book (and trying to read while jogging is not easy) or at least give it music to dissect. My concious mind would be happy eating, sleeping, and practicing reproduction, but my unconcious keeps driving me to do all these creative tasks.

    the unconscious mind does all the work, and the conscious mind is a manager.

    That is what I was attempting to state. Maybe the wall between them is extra thick for me. Or maybe I have stopped trying to use my concious mind for these I know my unconcious mind is better suited. That delegation would be good management if we were two people. And my last paragraph suggests that my subconcious is often the boss.

Thank you for expanding my mind.

    Anyway, "simulated annealing" seems to mean slowing things down until they reach a stable form. (Please correct me.)

Some data might be set to "Known Fact", so its accuracy would not be changed by the process. Our model is for every data to be checked against all other data.

    Input: My name is Ellen.
    Query: Do you think Mike is cute?
    Input: He is not my type.
    Query: What is your type?

    (I am assuming that any machine that interacts with humans would learn tact quickly or be unplugged.)

    The programming for a learning machine that can check new input against all existing data would be very complicated, which is why people who do AI programming tend to do only AI, and the rest of us avoid the area.

    There could be a point when all input was processed and the system was stable. So "simulated annealing" could describe that process. But new input must cease, or the system must be fast enough that each input is assimilated before another arrives. A time of "sleep" would stop the input.

    Both systems are mentioned in "When H.A.R.L.I.E was One". The periods of irrationality (sleep, dreaming) were needed to correlate the data until that point.
