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.

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.

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 don't want to see that two-tier Senegal, that two-tier Africa, when you have those at the top and those at the bottom, people who are hungry, people who do not have enough to eat.

There is no law, divine or human, that the saloon respects.

Everything I ever will be is because of Texas A&M University.

We know that in order for us to turn this around, it doesn't matter how many coaches they bring in here, assistants, weight trainers, whoever, we're the ones that are going to have turn it around. And I think just took that responsibility on ourselves.

The reactions haven't differed; the concerns have been different. When I read for a predominantly Indian audience, there are more questions that are based on issues of identity and representation.

I think I was very lucky that I didn't get well-known until my early thirties. If it had happened when I was younger, you might have seen me falling out of nightclubs. I think I conducted myself as a much better human being because I was already married when all that came along (I got married five months after I got the role as Will).

Drew Barrymore's Guess shoot took place as she was making the transition to serious actress after having been more known as a child actress who had become overwhelmed by the Hollywood lifestyle.

I am sure every movie I've made, even as an actor, had multiple test screenings. And I am sure there have been horrible things written about me. But I never have to see them!

There's a tendency in politics to attribute bad motivation much too quickly, and the sooner you attribute bad motivation to someone you disagree with, the harder it is to find some common ground to make some progress that would give people confidence that you got it more right than wrong.

A man can sleep on every hurt but his own.

Having fans wherever I go gives me an energy, and it is the source of my power.

I start with the premise that the function of leadership is to produce more leaders, not more followers.

If poetry and the arts do anything, they can fortify your inner life, your inwardness.

It was fantastic returning to 'Being Human'. When I got cast in the role, at first I just thought it was for one episode, and the fans were really great about it, and it was really nice having that reaction.

When you're on a series that's been cancelled, there's a little bit of a stink on you.

This galloping concentration in broadcast ownership is unhealthy.

Because of the grass and open face, I take one more club for shots from the rough, unless the ball is sitting on top of dry grass. Then, I use more loft and swing softer, trying to hit it about 70 percent to avoid a flyer over the green.

The woods always look different at night...as if the daytime trees and flowers and stones had gone to bed and sent slightly more ominous versions of themselves to take their places.

I want you to know that, despite what you might read at times in the newspapers or see on the television news, we have actually been getting a lot of things done the last several months, the U.S.-Canada relationship.

The only thing harder than leaving show business is coming back.

There are many comedians who are afraid to work outside the coasts and the casinos because they're afraid they'll bomb.

Part of me always longed to do just one more film and see what Luke would be like now that he's on the level of Obi-Wan Kenobi, the student having become the master. But it was not meant to be.

Everybody always talks about how they can't wait until they turn 18, so they can go out on their own and get their own apartment, and I'm like, 'I want to be with Mom!' I have it good.

Ambiguity supposes eventual resolution of itself whereas certitude implies further ambiguity.
