Meditation Can Improve Your Memory, Focus, and Productivity at Work - 0 views

  • Meditation Can Improve Your Memory, Focus, and Productivity at Work
  • If you haven't given meditation a try yet, despite the many advantages we've already seen (including chronic pain and stress relief, reducing information overload, and building a better brain), here's one more argument for trying the practice: meditation may help you get more done at work.
  • A recent study by University of Washington researchers (PDF) found that meditation training helped workers concentrate better, remember more of their work details, and stay energized and experience less negative moods.

  • The meditation group outperformed the others when it came to reduced stress, greater focus, and improved memory. The waitlist control group didn't have reduced stress until after they did the meditation training eight weeks later. The relaxation group, oddly enough, wasn't any less relaxed at work. Although the meditation training involved a two hour session each week, you could probably see similar benefits from just a two-minute daily meditation habit or regular use of tools like Buddify to help you get started meditating.

Memory News, Videos, Reviews and Gossip - Lifehacker - 0 views

  • Remember More Without Trying Too Hard
  • Memory is a tricky beast. You might sit and study for hours on end, but for some reason it never seems to stick with you. However, as Time points out, implicit learning relies on three factors that are easy to control.
  • You'll need to do three things when studying or learning a new skill: Give your mind a ton of material: This might seem obvious, but immersing yourself completely in what you're trying to learn is the first step to actually learning it. You don't have to actively try to memorize things, just expose yourself to the skill or material as much as possible. Practice: We tend to stop practicing a skill or stop studying when we think "we've got it." However, well after we learn something we still continue to refine that skill. Sleep: It's thought that sleep is essential to learning and remembering. Some studies have suggested that the brain identifies patterns in our memories and consolidates them to make them permanent when we're sleeping. In essence, a good night of rest might be better than an all-night study-fest.

Brew the Best Possible Coffee Without Breaking the Bank - 0 views

  • Brew the Best Possible Coffee Without Breaking the Bank
  • Consider yourself forewarned however, once you begin brewing better coffee it becomes increasingly difficult to go back to enjoying crappy coffee.
  • Nearly all the coffee in the world comes from two types of coffee plants: Arabica and Robusta. Arabica has roughly half the amount of caffeine and a more mellow taste. Robusta has more caffeine and higher acidic content which creates a significantly more bitter flavor.

  • The more you can do to preserve the integrity of the beans and the delightful flavor inside right up until the moment of brewing, the better the coffee will be. Keeping the beans intact for as long as possible helps immensely. If possible where you live, try to buy locally roasted beans to benefit from the freshness. Barring that, buying whole bean coffee is vastly superior to buying pre-ground coffee.
  • The refrigerator is the mortal enemy of your coffee. Taking coffee in and out of the fridge is a sure way to suck the flavor right out of it. Coffee that will be used frequently and immediately—whole bean or ground— is ideally stored in an air tight, opaque,and glass or otherwise inert container.
  • Storing an unsealed container of grounds or beans in the cold temperatures of either the fridge or freezer is a sure way to accelerate the its journey from delicious flavor to stale bitterness.
  • Using a French press is one of the simplest methods of brewing a fantastic cup of coffee. A French press is a glass cylinder that has a lid with a piston style rod attached to a circular screen. Grind your coffee, put a few heaping scoops in the bottom, pour nearly boiling water over the grounds, wait about four minutes, press the plunger down to push the grounds down and enjoy some delicious coffee. One of the primary benefits of making coffee in a French press over a standard drip pot is that more of the coffee oils end up in your cup instead of in the machine's filter. More oils means better taste!
  • While it might not be practical to install a reverse osmosis filter under your sink, the more pure the water you use for your coffee the better it will taste. A gallon of locally distilled water costs less than a dollar in most places and many supermarkets have cheap refills available—my local market has a machine that will refill a gallon jug for 35 cents. Even if you—for environmental or financial reasons—don't want to spend money on filtered or bottled water for your coffee you can still tweak your water. Fill up a pitcher of water the night before and set it out on the counter. While it's not the same as being filtered through the stony depths of a mountain aquifer it will allow some chemicals in the water like chlorine to dissipate.

Free online speed reading software | Spreeder.com - 0 views

  • preeder.com is free online speed reading software designed to improve your reading speed and comprehension. Spreeder is a free service provided by 7-Speed-ReadingTM.
  • Speed reading is the art of silencing subvocalization. Most readers have an average reading speed of 200 wpm, which is about as fast as they can read a passage out loud. This is no coincidence. It is their inner voice that paces through the text that keeps them from achieving higher reading speeds. They can only read as fast as they can speak because that's the way they were taught to read, through reading systems like Hooked on Phonics.
  • However, it is entirely possible to read at a much greater speed, with much better reading comprehension, through silencing this inner voice. The solution is simple - absorb reading material faster than that inner voice can keep up. In the real world, this is achieved through methods like reading passages using a finger to point your way. You read through a page of text by following your finger line by line at a speed faster than you can normally read. This works because the eye is very good at tracking movement. Even if at this point full reading comprehension is lost, it's exactly this method of training that will allow you to read faster. With the aid of software like Spreeder, it's much easier to achieve this same result with much less effort. Load a passage of text (like this one), and the software will pace through the text at a predefined speed that you can adjust as your reading comprehension increases.

  • To train to read faster, you must first find your base rate. Your base rate is the speed that you can read a passage of text with full comprehension. We've defaulted to 300 wpm, showing one word at a time, which is about the average that works best for our users. Now, read that passage using spreeder at that base rate.
  • After you've finished, double that speed by going to the Settings and changing the Words Per Minute value. Reread the passage. You shouldn't expect to understand everything - in fact, more likely than not you'll only catch a couple words here and there. If you have high comprehension, that probably means that you need to set your base rate higher and rerun this test again. You should be straining to keep up with the speed of the words flashing by. This speed should be faster than your inner voice can "read".

The Science Behind Why Power Naps Help You Stay Productive and Creative - 0 views

  • The Science Behind Why Power Naps Help You Stay Productive and Creative
  • Even if you don't work in a job where napping is acceptable, there's a very clear reason why the best naps are the ones that are usually around the half-hour mark.
  • The video above, from ASAP Science (worth subscribing to on YouTube if you dig videos like this) explains how sleep cycles work, and how power naps—or those naps that do the most to boost cognitive function during the day—take advantage of the first two phases of your sleep cycle: stage one, where you're probably "dozing," or feel relaxed but if someone woke you you probably wouldn't even notice you'd been asleep, and stage two, where your brain starts to consolidate memories, organize its biological bookshelves, and shuts the brain off from external, non-dangerous stimuli. If you're the type who says "It takes me 10 minutes just to fall asleep," that 10 minutes is probably leading you into stage one—after that, you're in stage two. The trouble comes in stage three, or the part where we're sleeping deeply, and waking is difficult. That's when you start to feel groggy, and hate the idea of getting up. If you hate mornings, you're probably waking up during this phase. So the key to getting all of the benefits of naps without the drawbacks is to sleep only for about a half-hour, or the time it takes your brain to go through the first two stages, but not enter the third.

What Caffeine Actually Does to Your Brain - 0 views

  • affeine is one seriously misunderstood substance. It's not a simple upper, and it works differently on different people with different tolerances—even in different menstrual cycles. But you can make it work better for you.
  • Luckily, one intrepid reader and writer has actually done that reading, and weighed that evidence, and put together a highly readable treatise on the subject. Buzz: The Science and Lore of Alcohol and Caffeine, by Stephen R. Braun, is well worth the short 224-page read. It was released in 1997, but remains the most accessible treatise on what is and isn't understood about what caffeine and alcohol do to the brain.
  • Caffeine Doesn't Actually Get You Wired Right off the bat, it's worth stating again: the human brain, and caffeine, are nowhere near totally understood and easily explained by modern science. That said, there is a consensus on how a compound found all over nature, caffeine, affects the mind.

  • Normally, when adenosine levels reach a certain point in your brain and spinal cord, your body will start nudging you toward sleep, or at least taking it easy. There are actually a few different adenosine receptors throughout the body, but the one caffeine seems to interact with most directly is the A1 receptor.
  • it functions as a supremely talented adenosine impersonator. It heads right for the adenosine receptors in your system and, because of its similarities to adenosine, it's accepted by your body as the real thing and gets into the receptors.
  • caffeine actually binds to those receptors in efficient fashion, but doesn't activate them—they're plugged up by caffeine's unique shape and chemical makeup. With those receptors blocked, the brain's own stimulants, dopamine and glutamate, can do their work more freely—"Like taking the chaperones out of a high school dance,"
  • caffeine very clearly doesn't press the "gas" on your brain, and that it only blocks a "primary" brake. There are other compounds and receptors that have an effect on what your energy levels feel like—GABA, for example—but caffeine is a crude way of preventing your brain from bringing things to a halt. "You can," Braun writes, "get wired only to the extent that your natural excitatory neurotransmitters support it." In other words, you can't use caffeine to completely wipe out an entire week's worth of very late nights of studying, but you can use it to make yourself feel less bogged down by sleepy feelings in the morning.
  • What's important to take away is that caffeine is not as simple in effect as a direct stimulant, such as amphet
  • amines or cocaine; its effect on your alertness is far more subtle.
  • The general consensus on caffeine studies shows that it can enhance work output, but mainly in certain types of work. For tired people who are doing work that's relatively straightforward, that doesn't require lots of subtle or abstract thinking, coffee has been shown to help increase output and quality. Caffeine has also been seen to improve memory creation and retention when it comes to "declarative memory," the kind students use to remember lists or answers to exam questions.
  • The effectiveness of caffeine varies significantly from person to person, due to genetics and other factors in play. The average half-life of caffeine—that is, how long it takes for half of an ingested dose to wear off—is about five to six hours in a human body. Women taking oral birth control require about twice as long to process caffeine. Women between the ovulation and beginning of menstruation see a similar, if less severe, extended half-life. For regular smokers, caffeine takes half as long to process—which, in some ways, explains why smokers often drink more coffee and feel more agitated and anxious, because they're unaware of how their bodies work without cigarettes.
  • regular caffeine use has also been shown to decrease receptors for norepinephrine, a hormone akin to adrenaline, along with serotonin, a mood enhancer. At the same time, your body can see a 65 percent increase in receptors for GABA, a compound that does many things, including regulate muscle tone and neuron firing. Some studies have also seen changes in different adenosine receptors when caffeine becomes a regular thing.
  • A 1995 study suggests that humans become tolerant to their daily dose of caffeine—whether a single soda or a serious espresso habit—somewhere between a week and 12 days. And that tolerance is pretty strong.
  • You start to feel caffeine withdrawal very quickly, anywhere from 12 to 24 hours after your last use. That's a big part of why that first cup or can in the morning is so important—it's staving off the early effects of withdrawal. The reasons for the withdrawal are the same as with any substance dependency: your brain was used to operating one way with caffeine, and now it's suddenly working under completely different circumstances, but all those receptor changes are still in place. Headaches are the nearly universal effect of cutting off caffeine, but depression, fatigue, lethargy, irritability, nausea, and vomiting can be part of your cut-off, too, along with more specific issues, like eye muscle spasms. Generally, though, you'll be over it in around 10 days—again, depending on your own physiology and other factors.
  • Beyond the equivalent of four cups of coffee in your system at once, caffeine isn't giving you much more boost—in fact, at around the ten-cup level, you're probably less alert than non-drinkers.

Boost Your Creativity by Improving Your Working Memory - 0 views

  • Boost Your Creativity by Improving Your Working Memory
  • In one study, the researchers actually explored the creativity of improvisations played by cellists with no formal training in improvisation. At the start of the study, they measured everyone's working memory capacity. Then, participants were given the chance to perform three 3-minute improvisations based on a theme (such as Winter or Spring). Each improvisation had a different theme. The improvisations were recorded in a studio, and then professional musicians rated them for their originality and creativity. The creativity of the first improvisations people performed was about the same regardless of their working memory capacity. However, the people with high working memory capacity played better improvisations as they progressed through the study, while those with low working memory capacity played worse improvisations. So, by the end of the study, the people with higher working memory capacity were playing significantly more creative improvisations than those with low working memory capacity.

You Could Be Better at Remembering Names, If Only You Gave a Shit - 0 views

  • You Could Be Better at Remembering Names, If Only You Gave a Shit
  • ome people are more tuned in to personal relationships—like politicians or teachers—and they're more apt to be good at remembering people's names because they're have an interest in remembering them. But for the rest of us, we may just simply not be that engaged when we meet someone.
  •  
    Something I have always realised, if people don't engage me, I cba to remember their name :)
