  1. Re:Highly questionable study on Video Games Can Make Us More Creative · · Score: 1

    Arousal means "excitement" more than anything.

    So "mildly pissed off" would be more aroused than not caring, but less aroused than screaming and raging. You're not going to be very creative if you have nothing to say, and neither will you be creative if you're so mad you can't think. Likewise, if you're overcome with joy, you'll be less creative than if you're just in a cheerful mood.

    What I think the study is saying is that DDR "regulates" your arousal, exciting you if you're bored and not interested in doing anything, and calming you down if you're too upset to do anything. It's like drinking a cup of coffee to wake yourself up, but not so many that you get jittery.

    It's an old finding with new supporting research.

    That's totally normal, don't worry about it.

    Most people can retain 7 +/- 2 (5 to 9) semantic "packets" of information. A "packet" can be a part of a larger packet. Most people can reliably recall 5 random numbers or letters in a row. Or 5 groups of 5 numbers or letters. Or 5 random words. Or 5 unrelated phrases.

    But don't try to memorize a paragraph worth of random letters and numbers -- that's more than 9 packets so it's almost impossible without a lot of repetition. That's why phone numbers have a dash in them, to break the number up into smaller packets that are easier to remember.

  3. Re:Ritalin is a great study drug. on Cognition Enhancer Research · · Score: 3, Interesting

    Cocaine, (meth)amphetamines, and methylphenidate actually have rather similar effects. They all boost dopamine. Ritalin is much slower acting, has a longer half-life, and is much less potent, and I think it has some other effects. Some kids crush and snort Ritalin for a cocaine-like high, and it's nicknamed "kiddie coke" IIRC. One of my junior high teachers told us she used to sell her pills when she was in school. I don't think addictiveness or anything have been fully studied. I was going to write a research paper on the subject a while ago, but I had trouble finding sources.

    I actually took Ritalin for a while in high school. It didn't do me much good, though it might now that I understand how it works. I wish I could try it again, knowing better, but of course it takes 8 months to get an appointment with my doctor.

    I've been taking melatonin for a little while to get myself to sleep (at a reasonable hour). The effect is so much better than any other sleeping pill I've tried that it's hard to believe. Feeling sleepy without feeling bone tired is so much more pleasant than feeling bone tired and drowsy, but not sleepy.

    I have no need for a change of opinion. I've thought eBook readers were the best thing ever since they were invented. There's a magic balance of "good enough" and "cheap enough" that hasn't really been reached yet, though, at least not for me. Until then I'm using my Samsung P2 (MP3/media player) which restricts me to .txt files but otherwise works great. (This isn't even really a bad thing -- I have a few years worth of classics to get through anyway, and many other formats can be converted easily.) The tiny form factor makes it very convenient to carry around. Plus 8GB of storage blows the Kindle away. And it plays videos. And it has (dull) games, and a calculator. The LCD is roughly 150 DPI so it's easy to read; with the brightness turned up it's even OK outdoors.

    I'm using an ATI All-in-Wonder Radeon 9600 on my desktop with a NEC LCD1712 monitor. That video card needs a proprietary driver to work with Linux. Without it, X won't start. After following some very complicated, hard to find instructions -- which I had to get off my laptop, because I couldn't access the web without X -- I managed to install Kubuntu and get the driver running. And then I broke it as soon as I tried to change a video setting. I didn't even get a command line because the monitor and video card weren't talking to each other.

    The sound card, a cheap old Creative SB-Live, needs a driver but that was relatively easy to install. Hard to find, though.

    My laptop is a Gateway Tablet PC with a sort of lousy Finepoint digitizer. Theoretically it works with Ubuntu if you take apart the "fpit" driver, change and recompile it, then "play around" with your settings until it works. It actually detected my pen for a couple of hours, then it broke before I got the tap/click working. I spent a week on it before I gave up.

    The Wi-Fi works on my laptop, sometimes. It detects all the networks but just won't always connect. It's sort of temperamental. It reminds me of my first mouse under Windows 3.1, which would only work if you loaded the driver before you loaded Windows, and then only about half the time, with no apparent explanation. I guess it just doesn't feel up to it some days.

    My Epson 1250 scanner scans at roughly 100 DPI only. I don't know what the heck is going on there.

    I still dual-boot Windows and Ubuntu on my laptop because I do need my tablet for tabletty things, but I like Ubuntu because it's a little easier on the battery, cleaner, I like the apps, and it's a little quicker. I went back to XP on my desktop, though.

    I consider myself a fairly advanced user, but not an expert. I've been playing around with computers for a long time, and while I'm really excited about Linux and I'm comfortable with the command line and editing configuration files, it was very difficult to get these things working. I gave up on some of them because it was just too time-consuming. If I couldn't do it, I wouldn't expect my mom to be able to do it. None of my hardware is "whacked out" -- it's all common, off-the-shelf stuff from major companies, except maybe the digitizer. It's not really Linux's fault so much as the companies, I'd say, but getting everything to work was far from trivial.

I've heard "Please place the last item scanned on the scanner and wait" so many times now. I put up with these machines, I even like them, but they are a bit annoying.

    Americans seem to be more willing to turn to animals to care for people. We're happier training a monkey or a dog to do a job than build a robot.

If a male character (such as Wolverine) gets screwed, it's usually to advance his own character, not someone else's.

    It's not a hard and fast rule, of course, but a general observation. There are plenty of counterpoints -- it's not like the boys don't get killed.

    The United States has THE highest incarceration rate (0.75%) in the world, by far. "The United States has 5% of the world's population and 25% of the world's incarcerated population."

    There are two reasons for this: widespread and efficient policing (compared to the countries with the lowest incarceration rates, at least) and laws that promote long sentences for crimes that are usually given shorter sentences in other countries. Crime rates are about the same in most developed countries (except that the US has a much higher homicide rate -- but that only accounts for a tiny proportion of crime).

    Most of those laws are due to the "war on drugs," which was ineffective and wasteful, and a mistaken study from the 1970s that suggested that treatment programs don't reduce crime (good ones do; not so good ones have no effect; strong programs -- and long sentences -- for people who are unlikely to re-offend anyway actually increase crime).

    Some people are leeches, I don't disagree on that, but many, many people in prison in the US have either been in too long, which makes it harder to reintegrate into society, or should be in a medical or psychiatric setting instead. Warehousing offenders rather than getting them out and into real jobs is enormously expensive, something like $100000 a year. That's, what, five average adults' income tax? If drugs and their dealers were paying taxes instead...

    The people running prisons know this, and lawmakers are realizing that they're throwing money away and are trying to turn things around. They don't talk about it much because it's political suicide to look soft on crime, but road money has to come from somewhere and raising taxes is just as unpopular.

    Let's put it this way: if any change at all reduces incarceration by 1%, that would save roughly $2 billion. Reduce it enough to match even China and you're looking at $15 billion freed up. That doesn't include court costs. That would pay for a hell of a lot of rehab.
