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

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.

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.

What I'm really interested in is this idea of a 'brain co-processor' - a device that can record from, and deliver information to, so many points in the brain, with a computational infrastructure in between - a computer that can process the information and compute exactly what needs to be restored.

You want the actor to be happy with the movie. You really want the actor to think they did a good job and all that.

I believe to go along to get along is unpatriotic. I believe that agreeing with your government on everything they do is unpatriotic. I believe a patriot stands up and holds your government's feet to the fire. Because if you do that, you will get good government.

Anger is often more hurtful than the injury that caused it.

Horror and panic themselves are forms of violence, and diminishing them, restricting their dimensions, is itself a civilizing act.

A large part of altruism, even when it is perfectly honest, is grounded upon the fact that it is uncomfortable to have unhappy people about one.

A good general always makes you search for his weaknesses.

You can have great players, but if they don't want to be coached, what are you going to do?

If you go on stage with the wrong attitude, or something in your performance is off, you can lose an audience in the first minute. That first minute is crucial.

My words thoughts and deeds have a boomerang effect. So be careful what you send out

I write the songs and hand it over to the world and see what happens. But the things that I've written for people that have been hits, I don't know that I would have directed them in the right path, but they definitely wound up on the right path.

You can always tell an old soldier by the inside of his holsters and cartridge boxes. The young ones carry pistols and cartridges; the old ones, grub.

There are 4 billion cell phones in use today. Many of them are in the hands of market vendors, rickshaw drivers, and others who've historically lacked access to education and opportunity. Information networks have become a great leveler, and we should use them together to help lift people out of poverty and give them a freedom from want.

If you can't do anything about it then let it go. Don't be a prisoner to things you can't change.

If you live in the elite world of dance, you find yourself in a world rife with racism. Let's face it.

Watch my dust.

I have to make it my job to be careful with my family.

'Lolita' was a great wound in the side for me. I stuck my neck out maybe further than I should have and castigated the studio for not getting behind it.

When a couple has a strong preference for a baby boy or girl, who is injured by allowing them to choose? Certainly not the child.

When a man keeps beating me to the draw mentally, he begins to get glamorous.

Talk about national interests: When we went in with Operation Iraqi Freedom, some of our allies, Turkey, for example, would not let us through. How much trouble did that cause us, because we were not able to go into Iraq through Turkey?

The tragedy is that political leaders failed so badly at delivering what Iraqis clearly wanted - and for that, a great deal of responsibility lies with Prime Minister Maliki.

One of the reasons that I'm still in the military - or I stayed in the military - is because I think the military has been a place where certainly people could improve, advance, and were treated fairly.

Try to find someone with a sense of humor. That's an important thing to have because when you get into an argument, one of the best ways to diffuse it is to be funny. You don't want to hide away from a point, because some points are serious, but you'd rather have a discussion that was a discussion, rather than an argument.
