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.

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.

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.

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 wish I could understand why so many people have a nearly manic desire to excuse, defend, explain or condone evil.

If I were in a room full of people, I'd rather be the person who is more interesting than the one who is wallpaper.

Few characters in history are indispensable.

It's not like I love dragons! Only on 'Game of Thrones!' Our dragons are amazing, and they look really real. But I think after 'Game of Thrones,' I won't be a fantasy fan.

It's such a nice change to get to play a wretched, shallow, mergers-and-acquisitions woman. My true colors come out.

If today I stand here as a revolutionary, it is as a revolutionary against the Revolution.

We've begun to put fear into those whites who think they can do anything they want to a black person and get away with it.

I don't want to sound too critical, but we're taking a wait-and-see approach on UltraViolet.

My mom lived with me until I started making enough money to support myself. I was asking her to leave the entire time. I'd been ready to move out since I was, like, 14.

I've got to keep my head out of trouble, because if it goes on, it would be 'Harry Potter boy this, Harry Potter boy that.'

I've learned to wait 'til an idea is worth making. That's not really a lesson I've learned; I sort of always did it that way. But there's no reason or need to make videos prior to when you make a show, because then you need material for it.

Every Halloween for six years, I was a Ninja Turtle, and Mikey was my favorite. The turtles really made me who I am today. They got me into martial arts, meditation, surfing, skateboarding; big time influence on who I am today.

Anyone who has to fight, even with the most modern weapons, against an enemy in complete command of the air, fights like a savage against modern European troops, under the same handicaps and with the same chances of success.

Secondly, I thought it was ridiculous to have two undercover policemen driving around in a striped tomato.

There will be no justice as long as man will stand with a knife or with a gun and destroy those who are weaker than he is.

Christ himself wrote nothing, but furnished endless material for books and songs of gratitude and praise.

I tried to film 'Leaves of Grass' in Oklahoma, but it was literally about a million dollars less to shoot in Louisiana.

I've played a lot of roles I haven't wanted to play, either because they needed someone in the theatre or because they couldn't do it without me 'cause they don't have anyone else the right age.

I think if you can get people to laugh, you can get people to listen.

Every book is like starting over again. I've written books every way possible - from using tight outlines to writing from the seat of my pants. Both ways work.

I was regarded as the school freak which further reinforced a lot of inhibitions and doubts I had about myself. I was a shy, frightened teenager for a long time.

Sanity calms, but madness is more interesting.

My best has to be for Barcelona against Villarreal in 2006 - that is the one I am asked most about, and it is the one I am most proud of. Xavi chipped the ball to me, I chested it down, twisted and hit an overhead kick. It was the final goal in a 4-0 win.

I want to give people a taste of the Caribbean, and show them the fun side of me.
