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.

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

Love is trembling happiness.

If you're a comic, you don't have a rehearsal room, you rehearse on stage. My main concern is remembering everything.

In Britain, it's bred into you, the idea that you can't really change anything, so why bother. When I went to school in America, it was the total opposite view - you, as an individual, can change anything and everything. It's how you're raised.

It's not that hard to eat well if you're willing to put a little more time into it, a little more thoughtfulness into it and, yes, a little bit more money.

There is a brilliant child locked inside every student.

We eventually learn that emotional closure is our own action. We can be responsible for it. In any moment we can choose to open or to close.

Mothers are the people who love us for no good reason. And those of us who are mothers know it's the most exquisite love of all.

In a state where corruption abounds, laws must be very numerous.

At what point is someone precluded from availing themselves of the justification of self-defense because of their own poor judgment or bad behavior?

Money is nothing really worth squabbling about. This is what puts people six feet under. You know, I don't need it.

Any misfortune that happens to another person is funny. If it happens to someone else and not me, it's very funny.

It takes a very strong brain to resist the absolutes, the myths that the media and the politicians peddle - the idea that if you are too kind, where does it all end? That not to help someone is somehow a good idea.

My life is, in a sense, trash. My life is only that of which the residue is my writing.

Happiness is never stopping to think if you are.

When I was signing up for the University of Southern California's music program, I flipped a coin to decide my major. If it came up heads, it would be flute - tails would be voice.

I don't want to sound like the old guy, but cynicism is a potential danger. It colors our way of looking at the world.

It will be a difficult couple of days. Its difficult now and it will be difficult tomorrow.

I am not a has-been. I am a will be.

Man loves company - even if it is only that of a small burning candle.

Refusing to ask for help when you need it is refusing someone the chance to be helpful.

Cancer stops you in your tracks. It really makes you think about what's important. In a second, life can change. Don't ever forget to say thank you for love and family. What good is your success without them?

The release date is just one day, but the record is forever.

Childhood is the one story that stands by itself in every soul.

Rudeness makes me very angry.
