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.

The whole Valentine's thing is fine, but you don't back it up right next to the biggest gift-giving holiday of the year. Unbelievable. And we find it acceptable.

It's always irritated me that people say, 'Where's the action? Oh wow, there's no action here; let's go somewhere else.' These people will never find the action.

A young man idle, an old man needy.

I got irritated with people asking us the same questions. Like, 'Are you a real band?' Journalists wanted to slay us, tried to cut us down, and I just started caring less and less about doing interviews. With Facebook and Instagram, you kind of don't need to anyway. But now and again, we'll do something when there's new information to share.

Being productive gives people a sense of satisfaction and fulfillment that loafing never can.

Human beings are much bigger than just making money.

I like the encouragement I get from doing new things. I like to feel scared or challenged in the hope that I can pull it off. That little bit of fear creates an energy that I can channel into the performance.

A story should have a beginning, a middle, and an end... but not necessarily in that order.

The first devices to record and play back music were the phonograph and the gramophone. The gramophone's inventor: Alexander Graham Bell.

Intelligence alone does not get us where we need to go or even necessarily where we want to go. For that, the human creature must exercise harder-won capacities of wisdom, and wise action.

When there's so much choice, it can get overwhelming and it's hard to make a choice.

Joaquin Sabina is one of my favorites. He's like a legend. He's like our Bob Dylan, or our Bruce Springsteen. He's one of the most talented writers of our Latin music.

When I'm picking songs for an album I always want a song that I can relate to and that I have experienced. There's nothing worse than watching an artist try and sell a song that isn't believable coming from them.

There's nothing wrong with making the best of one's declining years, but what does annoy me is the fatalism. Now that we're seriously in range of finding therapies that actually work against ageing, this apathy, of course, becomes an enormous part of the problem.

Dictatorship is like a giant beech tree very magnificent to look at in its prime but nothing grows underneath it.

Those who cannot attack the thought, instead attack the thinker.

A modest little person, with much to be modest about.

There might have been a period around 'Tango & Cash' when I was nearly fashionable. My problem is that my weight's always been changing for the movies I'm in.

I think the real understanding comes when we recognize our humanity in each other. That's not just between blacks and whites. That's between all religions as well.

I love uplifting television.

Sylvester has a great popular sense, as good as any writer I've ever worked with. He knows what audiences want to see, and what they don't want to see.

You do not have to have it all figured out to move forward.

For me, French is so rich and so sacred that learning it is like learning a foreign language.

Amy Carter, Chelsea Clinton and the Obama girls all had to change schools.
