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.

I work very quickly. I only ever take one picture of one thing. Literally. Never two.

I was bullied and regarded as little bit of an oddball myself.

I love creating models and coming up with explicit structures I can play with.

The first game of the year is always an in-season adjustment game.

Death is an ascension to a better library.

You're at the mercy of the editors' hands.

My mom was a big 'Smurfs' fan, so she would force me to watch every Saturday morning. I had no choice in the matter. I would jump downstairs on Saturday morning, 'Hurray, cartoons!' and she would say, 'Smurfs! That's what you're watching.'

I think the American West really attracts me because it's romantic. The desert, the empty space, the drama.

I wanted to make an image for myself as an outlaw type. A kind of rock 'n' roll sensibility.

A calling is you feel - you look out and see the need - maybe it's the need for the poor, to help poor people. Maybe it's the need to get involved in the race problem, as Martin Luther King was - felt called.

You find how you feel your best, whether you feel better when you're eating gluten-free or whatever it is. I feel better when I eat a burger every other night.

I get a lot of inspiration from research in mythology and folklore. I find that, you know, stories people told each other thousands of years ago are still relevant now.

We need 10,000 genomes, not 100, to start to understand the link between genetics, disease and wellness.

J.Crew's a great brand.

In many ways, the crumbling of the institution of marriage is the real 'war on women.' Marriage is the civilizing influence for men and for families.

There’s no need to be perfect to inspire others. Let others get inspired by how you deal with your imperfections.

I really got into 'The Walking Dead.' That was genius. And I have to say, my husband is on 'Shameless,' and I think it's a brilliant show.

Water is our most precious resource, but we waste it, just as we waste other resources, including oil and gas.

Basically, I started on stage yelling and I kept yelling, and then I yelled some more, and then I yelled even louder. I'm modulated now.

I don't owe one man one cent. Anywhere.

I was never quiet when I worked at @cnn, when we did dumb stuff. You can't just take the check & stay quiet. Truth demands a voice: speak up.

The greatest advances of civilization, whether in architecture or painting, in science and literature, in industry or agriculture, have never come from centralized government.

Food is a very sensitive subject for so many people.

The danger to society is not merely that it should believe wrong things, though that is great enough; but that it should become credulous, and lose the habit of testing things and inquiring into them; for then it must sink back into savagery.
