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.

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.

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.

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".

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.

I woke up thinking a very pleasant thought. There is lots left in the world to read.

What an extraordinary world it is.

I think it's important to find the little things in everyday life that make you happy.

I have my flaws too, but I am a professional who doesn't like to miss or lose.

Any kid that feels like they don't have any kind of future, whether they're on a street corner in Harlem or in a little town in Kansas where nothing happens, it's all out there for them. They can do whatever they dream or wish or see on television, or read about in the papers.

You pay more in wages, get more in in tax, you get people living a higher standard, you get more money. It's a kind of circle.

Comedy is the difference between how you see a person and how they see themselves.

America's future will be determined by the home and the school. The child becomes largely what he is taught; hence we must watch what we teach, and how we live.

If you're going to be at a job environment, you should love it. You shouldn't do it just for money. You should do it because you love it. And the money comes naturally.

The only way we can challenge Islamism is to engage with one another. We need to make it as abhorrent as racism has become today. Only then will we stem the tide of angry young Muslims who turn to hate.

Climate protection creates sustainability and jobs in the real economy - in construction, in the production of heavy machinery and in systems engineering.

I think it is a mistake to judge science by Nobel Prizes.

Sponsorship involves putting your own political capital at risk, so they are going to help that person to succeed. Women get promoted; they don't get sponsored. Women know they are on their own if they get that promotion.

If you see a biker chick hanging out with a group of bikers and associated with them, stay away. You'll know right away if a biker chick is free; if she's with someone, she's right by his side. Getting with somebody's old lady is a big no-no. That's more serious than anything in that world.

As I believe — I am, I can, I know.

I read way, way more Andre Norton than could possibly have been healthy. It was a short hop from her to the rest of the library's science fictional and fantastic holdings.

If I played tennis, I had to be in a dance class. I always had multiple activities, so I never had to count on any one of them to feel successful.

To experience positive/healthy emotions you don't need a big house or a nice car or a managerial job or a million dollar in your bank.

The central dilemma in journalism is that you don't know what you don't know.

The U.S. is off the spectrum in religious commitment.

Yes, but I have to say this: the band is going to decide where the band plays.

Sometimes going to jail is just the price you have to pay for social reform or social change.

There's calm in each and every day, we just need to practice reaching out for it.

Our quarterback is going to be Alex Smith.
