The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it.

Perhaps the most important discoveries are those which relate to the appropriate distribution of the periods of study...Acts of revision should be spaced in gradually increasing intervals, roughly intervals of one day, two days, four days, eight days, and so on.

From 1880 to 1885, Hermann Ebbinghaus ran a study about the memorisation of nonsense syllables, such as "WID" and "ZOF" by repeatedly testing himself after various time periods and recording the results. He plotted these results on a graph creating what is now known as the "forgetting curve".

Murre and Dros present a successful replication of Ebbinghaus’ classic forgetting curve from 1880 based on the method of savings. The forgetting curve has indeed been replicated and that it is not completely smooth but most probably shows a jump upwards starting at the 24 hour data point.

The speed of forgetting depends on a number of factors such as the difficulty of the learned material (e.g. how meaningful it is), its representation and physiological factors such as stress and sleep. Furthermore higher original learning also reduces forgetting. The rate differs little between individuals.

Spitzer tested 1939 the effects of a type of spaced repetition with over 3600 students who were learning science facts and showed that spaced repetition was effective.

Spaced practice is a feasible and cost-effective way to improve the effectiveness and efficiency of learning, and has tremendous potential to improve educational outcomes.

Memory formation becomes more effective with longer inter-stimulus intervals between training sessions because of decreasing temporal overlap between successive, short-lived learning traces.

Either you face the challenges in life head on or back out. And I am not someone to back out from challenges.

I have fantastic ideas.

One could reasonably argue that the Turkish pogrom against the Armenians during World War I qualifies as a crime against humanity, as does the United States' ethnic cleansing of Native Americans.

I try to be passionate about every aspect of my life, how I love my wife, how I serve my wife, how I serve God. In the same way, I try to be passionate about football. I try to serve my coaches with passion. I try to serve my teammates with passion. I try to serve God, through football, with passion.

They shaved my head, eyebrows. This is not a sci-fi picture. It's not a fantasy picture. You're dealing with something that's supposed to be in reality. But we had a genius makeup artist.

I don't want to be on the radio. I don't want to be on Mtv.

I grew up on the stage, where you just throw yourself into projects and don't get in your own way.

People who are given whatever they want soon develop a sense of entitlement and rapidly lose their sense of proportion.

Time is money, especially when you are talking to a lawyer or buying a commercial.

I wish people could acheive what they think would bring them happiness in order for them to realize that thats not really what happiness is.

I never wanted to be road comic.

I think the more stressful our times get, the more we look for fantasy escapes.

Cherish the memories treasure the bonding give importance to the one who make your life worthwhile assure each other that you will be there no matter how far one will go the tie will be stronger forever.

I had this inferiority complex as a child, as I was not good at speaking. I was also not good in studies or sports and would often flunk in four-five subjects.

I refused to conform to an image that a lot of people thought a president's brother should adopt.

I miss my dad, yes. But I try to honor his memory, as well as all the victims of Hurricane Katrina, through the love I have for all humanity, a love I try to express through my music.

When you're going into a game, you're not expected to hit a home run every game. You're just doing everything proper with proper swings.

I have to reign myself in a lot.

And this week, I am proposing legislation to strengthen our Open Records laws to make public access to our public records surer, faster, and more comprehensive.

Expressing political opinion can be a powerful way to establish a character's voice when writing fiction.

I defy you to find any real will, any reasoning force, outside of life. And everything is there; there is, in the world, no other will than this force which impels everything to life, a life even broader and higher.

Crime is to man as fleas are to dog the likelihood of its presence increases as the quality of ones personal circumstances decreases.

Our party is a diverse one, as is my home state of Illinois.

As human beings, we are all flawed. And just like there is a good side, there is also a bad side waiting to find its way out.
