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.

Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of... permanent renewable energy sources, like solar power.

It's great to listen to men talk about sports or fights or war or even hunting sometimes, but the presence of the other, the presence of art and beauty, which crude masculinity seems to discount, is essential. Real civilization and real manhood seem to me to include those.

I make cameos in all my movies for no particular reason other than a joke. It's just a Hitchcock thing.

I learned a lot from Xavier Cugat.

I think it's kind of nice, in this day and age of instant gratification, that you have to wait for something.

I've been around a long time, and life still has a whole lot of surprises for me.

There is no present or future only the past happening over and over again now.

Any good actor is a character actor.

I've always been a very competitive person.

I came from a communist country where there are no luxury cars.

Twenty-eight years in business and you understand the importance of problem solving and the importance of efficiency, because if you don't become efficient, you don't run a business well, and you are out of business. And I think some of those principles could be applied to leadership in Washington.

When I write fiction, I never try to deliver a message; I just want to tell a story. But I admit that I want the story to be memorable and the characters to touch the reader's heart.

I am very excited - it's a big opportunity for me to play for Manchester United, a new challenge for me. I will try to do my best.

Camouflage is a game we all like to play, but our secrets are as surely revealed by what we want to seem to be as by what we want to conceal.

Romantic love came under attack, first from the Freudians and then from the neuroscientists, who said that being in love was a chemical reaction in the brain. Marriage is no longer seen as a lifetime commitment.

In my life, I've never really listened to when people start forming opinions on how you should be doing things.

I'm always shy and timid when I write in front of people.

My first gig was at Radio City Music Hall when I was 13.

We wanted to set a good example for the growing number of divers watching.

Sometimes a person has to be dead a while before people can appreciate what they did when they were alive.

I've never in my life said I didn't want to have children. I did and I do and I will!

A TRUE boyfriend is someone that will take care of his girlfriend stand up for her when needed and love her for who she is and not pretend to care about her

In the fell clutch of circumstance, I have not winced nor cried aloud: Under the bludgeoning of chance my head is bloody, but unbowed.
