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.

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".

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.

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 want to be Kanye and do what he does musically. I'm very fearless.

The bachelors admired freedom is often a yoke for the freer a man is to himself the greater slave he often is to the whims of others.

Up until the age of 9 or so, I was an incredibly happy, pretty well-adjusted, funny kid who made my parents laugh all the time. I was a bit of a clown, and I was really happy. And then my parents divorced, and I kind of turned into a different person.

We younger Negro artists who create now intend to express our individual dark-skinned selves without fear or shame. If white people are pleased, we are glad. If they are not, it doesn't matter. We know we are beautiful. And ugly too.

I've always been multi-cultural myself. I'm not black and I'm not white and I'm not pink and I'm not green. Eartha Kitt has no color, and that is how barriers are broken.

Every adversity, every failure, and every heartache carries with it the seed of an equivalent or a greater benefit.

May my soul bloom in love for all existence.

When you change the way you look at things the things you look at change.

Two or three things I know for sure, and one is that I'd rather go naked than wear the coat the world has made for me.

I go through a whole process with the actors first, building and creating characters, then I encourage them to sort of live in that character when they're in the screen.

In boxing it is about the obsession of getting the most from yourself wanting to dominate the world like a hungry young lion.

I was so overprotected, I used to think I was as delicate as people said I was.

If you don't go to other men's funerals, they won't go to yours.

One of the first things I learned about acting was, the only person you compete against is yourself.

I think people who read Internet blogs are usually trying to fit it in during a busy part of their day, and there's only so much information that you digest. Whereas an experience with a book is a little more comfortable, and I think people are a little more willing to really delve into information.

Grant me the treasure of sublime poverty: permit the distinctive sign of our order to be that it does not possess anything of its own beneath the sun, for the glory of your name, and that it have no other patrimony than begging.

If you have the opportunity to go be an early employee at a company that's just going crazy, and you believe it's the next Facebook or Google, you should go join that company.

Today, if I could get a job, with face tattoos, being a professor, I would do that. I don't know what university would hire me, but that's my passion.

Start in a small TV station so you can make all of your embarrassing mistakes early and in front of fewer people!

The idea that popular arts were shallow by definition and the traditional arts were profound was dead, I thought, and I wanted to prove it.

When you make a movie, it's up to so many things and so many people.

I just don't want to do a movie because it paid me a lot of money.

It depends on where you put the paint, not how much you splash on.

When I was speaking about communicating, I meant that the listener - we have to reach the listener; otherwise, of course, you're writing the piece, as I say, only for the satisfaction of seeing it on the paper for yourself, and then it ends right there.
