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".

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.

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.

When I was on my own in a hotel room in Romania, I had the imagination to keep myself occupied.

Perhaps McCain has opposed affirmative action for so long that he doesn't know it's about inviting more people to meet standards, not lowering them.

Maybe I have this fascination with the dark side because I live in the light. I don't have any dysfunction, and I've never experienced trauma.

I would like to be able to be both a film actor and a stage actor - to be an American actor in the style of a lot the English actors who do films. They are these wonderful actors who can do everything.

Giving is the highest expression of potency...Giving is more joyous than receiving not because it is a deprivation but because in the act of giving lies the expression of my aliveness.

I've realized as well after five years of being on the road that if I'm going to four or five months of my life to something even if I'm overpaid, it's four or five months of my life away from home, away from my son, away from family and friends. I better believe in it on some level even if it's a big movie.

No verse is libre for the man who wants to do a good job.

It's interesting about classical music that the more you hear something, the more you get to know a piece, the better and better it gets, period, which is just an interesting thing on it.

The truth for me is that I've been doing independent film since the get-go, so that's a big passion of mine, but the big ones are really fun, too. I like my world to be eclectic.

Studying music involves a lot of mathematics and a lot of exercises of memory. Or you've got to be able to be like somebody, to play like somebody, to play Mozart's music the way he played it and how he intended it. You've got to make it perfect, and that's not what I want to do. Although it is beautiful.

When I interview people, and they give me an immediate answer, they're often not thinking. So I'm silent. I wait. Because they think they have to keep answering. And it's the second train of thought that's the better answer.

There is not a job I've held in my career that was held by a woman before me.

Things gained through unjust fraud are never secure.

Any enterprise that is serious about experiencing the power of Big Data in real-time should be looking at DataTorrent.

New York may be the city that never sleeps, but Shanghai doesn't even sit down, and not just because there is no room.

In the wintertime, in the snow country, citrus fruit was so rare, and if you got one, it was better than ambrosia.

The time has come to end social promotion in our schools.

Knowing others is wisdom, knowing yourself is enlightenment.

There is nothing quite so depressing as waking up to face a day when you know that you are going to have to deal with a government office or bureaucrat.

I was supposed to be the antithesis of Frank.

With my husband, I have twice sailed across the Atlantic in a sailboat one third the length of the Mayflower. I know Atlantic gales inside and out. I endured one that lasted for three days with winds up to fifty knots.

Glory to God in highest heaven, Who unto man His Son hath given; While angels sing with tender mirth, A glad new year to all the earth.
