How to improve your memory

Draw it to remember it. Good trick to know.

Here’s the Memory Trick That Science Says Works — You draw it

Jeffrey Kluger | April 22, 2016

If the brain could brag that’s pretty much all it would do. It’s easily the most complicated organ in your body, and, more than that, the nimblest computer that has ever existed. But the brain has a bug and everyone knows is: memory. No matter how powerful its operating system becomes, its storage system stinks.

Even in childhood, when the brain is as clear and uncluttered as it will ever be, memory is still imperfect, given to random failures, depending on how rested we are, how attentive we’re being and a range of other things. Now, a new paper published in the Journal of Experimental Psychology suggests an unusual strategy for improving it: drawing.

As long ago as 1973, investigators were studying the memory-boosting advantage of so-called dual-coding—the way that a combination of both thinking about an object or activity and drawing a picture of it can make us remember it better. Research did show that the strategy worked, but the studies were both sparse and flawed, failing to account for the mere fact that it takes longer to draw a picture than, say, write a word, and whether writing the word in a more time-consuming way—using elaborate calligraphy, for example—would thus boost recall too.

In order to tease out those and other variables, a group led by psychologist Jeffrey D. Wammes recruited sample groups of students and ran seven different trials of essentially the same experiment on them. In all of the trials, the scientists started with a list of 80 simple words—all nouns and all easy to draw, such as balloon, fork, kite, pear, peanut and shoe. A random series of 30 of those words were flashed on a screen along with instructions either to draw the object or write down its name. After the 30 words, they would perform a filler task—listening to a series of tones and identifying whether each was low-, high-, or medium-pitched. That task had nothing to do with the study, except to get the subjects’ minds off of what they had just done, so that the memories could either consolidate or, just as often, vanish. Finally, they would write down a list of as many of the objects from the first test as they could.

In most of the trials, the subjects got 40 seconds to draw their picture, but in one they got just four seconds. In another variation, they would draw the object or write the word or, as a third option, list its descriptive characteristics. In another, the third option would be to visualize the object. In yet another, they would write the word as elaborately and decoratively as possible.

But no matter how many variations of the test the researchers ran, one result was consistent: Drawing the object beat every other option, every single time.

We observed a significant recall advantage for words that were drawn as compared to those that were written. Participants often recalled more than twice as many drawn words.

said Wammes in a prepared statement.

Just why this is so is not clear. One past theory had been that drawing requires what the researchers call a deeper LoP—or level of processing. But the trial in which the subjects were required to list the characteristics of an object went pretty deep too, and it didn’t make a difference. Another theory had been that drawing simply takes longer, but the four-second trial appeared to debunk that.

For now, Wammes and his group are speaking only generally, concluding that drawing encourages

a seamless integration of semantic, visual and motor aspects of a memory trace,

as they wrote in their paper. It will take more work to put flesh on those theoretical bones. For now, however, they only know that the technique works—providing a long-awaited software patch for the computer inside your head.

What is the connection between Music and the Brain?

Music is a powerful tool for the brain. Classical music has been studied for many years for its influence in the brain. Scientists have come to a conclusion that music is a valuable therapy for many diseases.

Norman Doidge has talked about Mozart music therapy in his book. He says it is a very useful therapy for Autism. Other studies have proven that music therapy is helpful in stress reduction and improvement of literacy skills in children.

Music has a harmony and frequency. These two attributes are important for the brain. The brain likes to hear certain frequencies at certain moments. When we are happy we can hear loud music and enjoy it. When we are angry we only accept to hear certain frequencies. Experiments show that in angry moments we like to hear classical music as it calms the brain down. It is very interesting to see the brain scans before and after listening to music, and the way they change. In a brain scan the red areas are the ones with a higher blood circulation, that show more stress. When a person listens to music these areas are reduced.

In his book Norman Doidge says that Mozart music can improve the symptoms of Autistic children. He mentions a physician who uses Mozart music as a therapy for healing Autistic children. He changes the frequency of the music a bit to make it more approachable to his goal. The therapy lasts and in certain days children listen to a certain frequency.

The frequency that the brain likes to hear the most is 90Hz to 110Hz. Norman Doidge thinks this therapy can be used for many brain illnesses as anxiety or depression.

The music therapy helps to make the myelin cover in n axon thicker, which helps to improve the firing of neurons faster, and releasing all toxins. After the therapy the scans of the brain showed that there was small amount of stress and anxiety and the person’s brain was healthier.

In conclusion music is a therapy for the brain. It helps the brain be more efficient. It helps the literacy and auditory skills in children if they are exposed to music in early years of their life.

Why you can not Get a Good Sleep in Someone Else’s Bed

Half of your brain may be staying awake to keep watch when you sleep in someone else’s bed…

Whether you’re staying in a hotel or having a sleepover, you never sleep quite as well on a bed that’s not your own.
That’s an observable fact. When scientists have people sleep in a lab for an experiment, they often toss out the first night of data because people sleep so poorly. But before now, they haven’t known why.
In a small new study published in Current Biology, researchers from Brown University found out what goes on in the brain when a person sleeps in an unfamiliar place. They measured brain activity during the deep sleep of 35 young, healthy people.

The researchers found evidence that something unique indeed goes on in the brain during the first night: one hemisphere of the brain, the left, shows wakefulness while the other shows sleep.

This alertness during sleep in half of the brain has been observed in other animals—including whales, dolphins and birds—and is thought to act as a kind of night watch.

“The environment is so new to us, we might need a surveillance system so we can monitor the surroundings and we can detect anything unusual,”

says Masako Tamaki, one of the authors of the study and research associate at the Laboratory for Cognitive and Perceptual Learning at Brown University.

We’re most vulnerable when we’re asleep, in other words, and by staying partially awake, our brains might be trying to protect us.

Our brain remain active when we sleep. researchers also found that when they outfitted the people in the study with earphones, the left side showed a larger brain response to high-pitched sounds than the right—suggesting more vigilance in that hemisphere.

The study raises a lot of unanswered questions; researchers don’t yet know why they saw this effect in the left hemisphere and not the right. But interestingly, both of these asymmetries only occurred on the first night—something to keep in mind the next time you can’t fall asleep in a strange place.
