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.

The eagle has no fear of adversity. We need to be like the eagle and have a fearless spirit of a conqueror

Sexual performance problems, such as impotence and frigidity, are 70 to 90 percent changeable. But a homosexual who wants to be a heterosexual - that's close to unchangeable. And a transsexual - say a man who believes he's really a woman in a man's body - is completely unchangeable; you'd have to change the body to conform to the psyche.

I'm born and raised in the Northeast. My parents are Irish immigrants. So our tendency is to shy away from the big yellow ball that comes up in the sky every once in a while.

Self-doubt kills talent.

Children enhance you.

I want to feel passion, I want to feel pain. I want to weep at the sound of your name. Come make me laugh, come make me cry... just make me feel alive.

I kept saying that I'd never live in L.A., and I didn't think I would. But that's where the work is, and I ended up making a lot of friends there, and my old friends moved out to Los Angeles too. And also, I think when you're famous, its hard to live in a small town.

You can reach higher heights by faith.

If I look back down the years, how I was treated as a kid, if it wasn't for the teachers at my school, then I wouldn't have achieved what I have. You have to look where you came from, and we do need to get more parents involved, more running clubs and more schools. They can make a difference.

I find it upsetting to see the erosion of manners. It's very scary. Where are the 'pleases' and 'thank yous?'

You sort of start thinking anything's possible if you've got enough nerve.

What I'm hoping to do and what I think I will do is make an entertaining enjoyable show where the whole family can sit down and watch.

What we may think is funny or cute may end up being powerfully hurtful.

There's a lot of politics over who gets the next allocation of Congressional funding.

Life moves so fast. You gotta document the good times, man.

In England, you laugh at yourselves; in France, we laugh at others.

America was born as a nation of immigrants who have always contributed to its greatness.

I believe the preservation of the home in the future lies almost entirely in the hands of men.

If anybody doubts my loyalty to my country, I'll punch him in the nose, and I don't care how old he is.

One thing I probably share with everyone else in the astronaut office is composure.

Daily repetition matters when a kid is learning to swim. It can be 20 minutes in a lesson or an hour practicing for a couple of weeks.

My name, Solange, means 'Angel of the sun,' and I'm completely enamored of my African history. The culture is so expressive.

There are some kinds of Christianity that insist you have to believe literally in doctrine. The Gnostic gospels open out the complexity and multiplicity of approaches to this. If you think the story of the virgin birth is mistranslated for instance it doesnt mean you have to throw out the whole thing.

Web servers are written in C, and if they're not, they're written in Java or C++, which are C derivatives, or Python or Ruby, which are implemented in C.
