Scientists Discover Why It Is Necessary For Our Brains To Forget What We Learn

Scientists Discover Why It Is Necessary For Our Brains To Forget What We Learn

Ever wonder why you forget things and remember others? What if I told you that just as your brain has certain signals for how to remember things, it also has certain signals to tell it what to forge? This information, coming from Lund University in Sweden has been supported by some compelling research. There are several reasons why your brain may forget information but it boils down to a simple concept — when you brain has one stimulus it tends to remember the information associated with this stimulus. In cases with multiple stimuli, you may forget because your brain does not know what to “assign” the association to. This information can change the way you learn and update the way teachers educate their students.

Examples of Mechanisms to Help Learn

After looking at the research conducted from Lund University, I realized it began a little bit like Pavlov’s study where he conditioned his dogs to salivate at the anticipation of food. At Lund University, they wanted to see if animals could learn to associate a certain tone or light pattern to a puff of air blown into their eye. The air buff in their eye causes the reaction of a blink. Therefore, eventually the tone or the light would make the animal or human blink before the puff had even been triggered. They found much like Pavlov’s dogs, this did work. When either the light or the tone was played the conditioning took affect and the subjects blinked as expected.

The Twist

The scientists then did something a little different with the study. Instead of having one stimulus, they decided to have a tone and the light signal at the same time. Some would think that this would reinforce the conditioning now that there were two things “warning” of the impending air puff. The result was somewhat surprising. Amazingly, the subjects were less likely to react to the two stimuli put together. The results got worse instead of better when there were two “warnings” given to the subjects.

As explained by one of the Swedish brain researchers: “Two stimuli therefore achieve worse results than just one. It seems contrary to common sense, but we believe that the reason for it is that the brain wants to save energy.”

The “Energy-Saving Brain”

Maintaining the pathways through the brain for both the tone and the light takes more energy than only having one. It is believed therefore that the brain temporarily lets go of the information. Basically, when two pathways are developed the pathways put on the brakes in the brain. It’s like an “I thought you were going to take care of it.” “No, I thought you had this” type of conversation between the two pathways that result in freezing up.

The Lund researchers were able to show how nerve cells learn and forget through animals, but think humans should probably be the same. The two stimuli simultaneously activate neurons which stop the activity.

What Does This Mean in Practical Use?

In practical use, this information could help teachers to learn how best to present information, so they aren’t accidentally shutting off learning mechanisms while teaching. Students might find this information very valuable. Knowing how to best study and retain information would be valuable. If scientist can figure out how the pathways are shut off by stimuli or outside things, than it’s reasonable to assume that they can find what turns them on. Imagine being able to attend school and knowing exactly what will make the information stick! The potential impact of this information is significant!

10 Famous Failures to Success Stories That Will Inspire You to Carry On

10 Famous Failures to Success Stories That Will Inspire You to Carry On

Failure occurs everyday, in school, jobs, housework, and within families. It is unavoidable, irritating and causes pessimism.

While the thought of flinging your hands in the air and walking away is all too appealing, take a second to connect with the people who have been there and survived.

Here are 10 famous failures to success stories around the world that will inspire you to keep going and achieve greatness:

1. J.K. Rowling

J.K.-Rowling

    During a Harvard commencement speech, Harry Potter author J.K. Rowling outlined the importance and value of failure.[1]

    Why? Simply because she was once a failure too.

    A few short years after her graduation from college, her worst nightmares were realized. In her words,

    “I had failed on an epic scale. An exceptionally short-lived marriage had imploded, and I was jobless, a lone parent, and as poor as it is possible to be in modern Britain, without being homeless. The fears that my parents had had for me, and that I had had for myself, had both come to pass, and by every usual standard, I was the biggest failure I knew.”

    Coming out of this failure stronger and more determined was the key to her success.

    2. Steve Jobs

      The now revolutionary Apple started off with two men in a garage. Years later we all know it as a $2 billion company with over 4000 employees.

      Yet, almost unbelievably, Steve Jobs was fired from the very company he began.

      The dismissal made him realize that his passion for his work exceeded the disappointment of failure. Further ventures such as NeXT and Pixar eventually led Jobs back to the CEO position at AppleJobs said in 2005:

      “I didn’t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me.”

      Lost your job today? Keep kicking and you could be just like this guy!

      3. Bill Gates

        Bill Gates was a Harvard dropout. He co-owned a business called Traf-O-Data, which was a true failure.[2]

        However, skill and a passion for computer programming turned this failure into the pioneer of famous software company Microsoft, and the then 31-year-old into the world’s youngest self-made billionaire.

        In his own words:

        “It’s fine to celebrate success but it is more important to heed the lessons of failure.”

        This isn’t to say that dropping out of Harvard will make you into a billionaire, but maybe that shiny degree isn’t worth as much as the drive and passion to succeed.

        4. Albert Einstein

          The word ‘Einstein’ is associated with intelligence and synonymous with genius. Yet it is a famous fact that the pioneer of the theory of general relativity, Albert Einstein himself, could not speak fluently until the age of nine. His rebellious nature led to expulsion from school, and he was refused admittance to the Zurich Polytechnic School.

          His earlier setbacks did not stop him from winning the Nobel Prize in Physics in 1921. After all, he believed that:

          “Success is failure in progress.”

          To this day, his research has influenced various aspects of life including culture, religion, art, and even late night TV.

          Just because you haven’t achieved anything great yet, doesn’t mean you can’t be an Einstein yourself.

          5. Abraham Lincoln

            Failing in business in 1831, suffering a nervous breakdown in 1836, defeated in his run for president in 1856, Abraham Lincoln was no stranger to rejection and failure. Rather than taking these signs as a motivation for surrender, he refused to stop trying his best.

            In this great man’s words:

            “My great concern is not whether you have failed, but whether you are content with your failure.”

            Lincoln was elected in 1861 as the 16th President of the United States of America.

            The amount of rejection you receive is not a defining factor. Success is still within your reach.

            6. Michael Jordan

              “I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. 26 times, I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.”

              This quote by retired basketball legend Michael Jordan in a Nike advertisement speaks for itself.

              It would be an easy misconception that Jordan’s basketball skills revolve around natural talent. In fact, in his earlier years,  basketball coaches had trouble looking past the fact that Jordan didn’t reach the minimum height. It was years of effort, practice, and failure that made the star we know today.

              7. Steven Spielberg

                Regarded as one of the most influential filmmakers of all time, Steven Spielberg is a familiar household name. It is surprising to realize therefore that the genius behind Jaws and E.T. had poor grades in high school, getting him rejected from the University of Southern California three times.

                While he was in college, he caught the eye of executives at Universal, who signed him as a television director in 1969. This meant that he would not finish his college degree for another 33 years.

                Perseverance and acceptance of failure is the key to success, after all.

                “Even though I get older, what I do never gets old, and that’s what I think keeps me hungry.”

                Bad grades in high school aside, there is no questioning the genius involved.

                To date, Spielberg has directed 51 films and has been awarded three Oscars.

                8. Walt Disney

                  Mickey Mouse creator Walt Disney dropped out of school at a young age in a failed attempt at joining the army.[3] One of his earlier ventures, Laugh-o-Gram Studios, went bankrupt due to his lack of ability to run a successful business. He was once fired from a Missouri newspaper for “not being creative enough.”

                  Yet today, The genius behind Disney studios is responsible for generations of childhood memories and dreams. From Snow White to Frozen, Disney will continue to entertain the world for generations to come.

                  The logic behind this is simple:

                  “We don’t look backwards for very long. We keep moving forward, opening up new doors, and doing new things, because we’re curious… and curiosity keeps leading us down new paths.”

                  9. Vincent Van Gogh

                    During his lifetime, Vincent Van Gogh suffered mental illness, failed relationships, and committed suicide at the age of 37.

                    He only ever sold one painting in his life, pinning him a failure as an artist. However that did not put a damper on his enthusiasm and passion for art.

                    He would never know that years and years after his death he would become known as a key figure in the world of post-impressionism, and ultimately, one of the greatest artist that ever lived.

                    He would never know that he became a hot topic in art classes and his image was going to be used in TV, books and other forms of popular culture.

                    In the words of this great, but tragic man:

                    “If you hear a voice within you say ‘you cannot paint,’ then by all means paint, and that voice will be silenced.”

                    10. Stephen King

                    01-Stephen-King-Rags-to-Riches-Celebs-1

                      As a paranoid, troubled child, tormented by nightmares and raised in poverty, it is no surprise that Stephen King grew up to the title: “Master of Horror”.[4]

                      An addiction to drugs and alcohol were his mechanisms to cope with the unhappiness he felt with his life. The frustration he felt towards multiple rejections by publishers in combination with illicit substances caused him to mentally contemplate violence towards his own children.

                      These intense emotions were those that he focused onto his writing. And that’s why he said:

                      “We make up horros to help us cope with the real ones.”

                      Writing became his new coping mechanism, and this is how the master author we know today grew to success.

                      Fail more often in order to succeed

                      Like Albert Einstein said, failure really is just success in progress. If you’d rather not to fail, you will probably never succeed.

                      Success comes from moments of frustrations when you’ll be most uncomfortable with. But after you’ve gone through all those bitter times, you’ll become stronger and you’ll get closer to success.

                      Don’t be afraid to fail. In fact, start failing, and start failing often; that’s how you will succeed.
