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 believe that in the pursuit of education, individual desire is more influential than institution, and personal faith more forceful than faculty.

You have to see if the batsman is coming out, if he is staying back, what his grip is like, to gauge his intentions. A common trend I have observed is, a lot of batsmen change their grips when they are looking to hit: normally they either go high or slide their hand to the bottom of the handle to get maximum power.

My son died from cancer. My granddaughter died from cancer. I have a lot of reasons to think that reality is not a friendly neighborhood. And the stories that I tell distract me, and if I do the job right, they distract people from things that are happening to them that they wish had never happened.

Singing is not indulged in by Rotary clubs of some countries and all clubs are given full privilege to do as they please about including it in their programs.

Learning to distinguish the illegal immigrant from the legal immigrant does not solve the problem of illegal immigration.

Amongst Women concentrated on the family, and the new book concentrates on a small community. The dominant units in Irish society are the family and the locality. The idea was that the whole world would grow out from that small space.

People might not think that, but the Republicans have all of the cards. And this is the time to get rid of Obamacare. This is the time to make the great deal.

I support mosques, obviously. We need churches, temples, mosques. Whatever people use to speak with their god or to receive spiritual inspiration is good for the country. But the symbolism of it at ground zero, within two blocks or three blocks, I believe is wrong.

It's a great dynamic. The dynamic between men and women in the workplace is really interesting.

I thought it'd be cool to start my own university, in a way.

All Plutophiles are based in America. If you go to other countries, they have much less of an attachment to either the existence or preservation of Pluto as a planet. Once you investigate that, you find out that Disney's dog Pluto was sketched the same year the cosmic object was discovered. And Pluto was discovered by an American.

I used to have friends come on tour and work as my drum tech, but they get bummed out when I have to tell them what to do. This time I'm just going to fly them out and let them hang. It's all good.

I don't think that Iran with a nuclear capability will be just the problem of the state of Israel. This is a matter that concerns the whole world.

Like a cyclone, imperialism spins across the globe; militarism crushes peoples and sucks their blood like a vampire.

Most women's pictures are as boring and as formulaic as men's pictures. In place of a car chase or a battle scene, what you get is an extreme closeup of a woman breaking down.

Believing in everything looks a lot like believing in nothing.

Friends applaud, the comedy is over.

Gluttony is the parent of disease.

Lazy people, the truly lazy people live on information, strategies, ideas, plans and many other criticals, simply to spend one hour of hard work and make the rest feel like a breeze.

The threat to Russia isn't liberal Europe or America. It is nonliberal Islam and nonliberal China. Russia has to change. It can't be otherwise. It will take time. You have to be patient.

Probably every book I read influenced me in some small way. Authors like Jan Westcott, Kathleen Winsor, Catherine Cookson, Georgette Heyer, and even Barbara Cartland taught me to write character-driven stories.

I know a lot of people who are very good at their craft who have learned - people behind the camera - who really have a lot to offer because they know what they're doing, they know what to do, they've made their mistakes.

Always do right. This will gratify some people and astonish the rest.'

Every day, you'll have opportunities to take chances and to work outside your safety net. Sure, it's a lot easier to stay in your comfort zone.. in my case, business suits and real estate.. but sometimes you have to take risks. When the risks pay off, that's when you reap the biggest rewards.
