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".

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.

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.

Nobody else took what I was doing seriously, so nobody would want to work with me. I was thought to be a bit eccentric and maybe cranky.

However, in modern conceptual frameworks there is a more sophisticated view. I would say that the act of music exists in several worlds simultaneously.

I am successful in my daily life.

I get noticed for different things I've done in different areas of town. If I'm in a rock club, it'll be Skid Row, if I'm in a mall it's the 'Gilmore Girls.'

My neighbor doesn't want to be loved as much as he wants to be envied.

Anything that changes your values changes your behaviour.

When I was pregnant. I exercised and was healthy, but it was also the first time since I was 14 that I wasn't on a diet.

I've never found that it jars to go back and forth.

Things don't turn up in this world until somebody turns them up.

I myself identify as a recovering Blockhead. You'd be surprised how many twenty- and thirty-something hipster chicks have the NKOTB skeleton in their closet, albeit artfully concealed by stacks of Ksubi skinny jeans and ironic Judas Priest T-shirts.

Nothing is so galling to a people not broken in from birth as a paternal, or, in other words, a meddling government, a government which tells them what to read, and say, and eat, and drink and wear.

The only logical thing I can think of is that I knew there were such things as artists, and I knew there were none where I lived. So I knew that to be an artist you had to be somewhere else. And I very much wanted to be somewhere else.

In addition to contributing to erosion, pollution, food poisoning, and the dead zone, corn requires huge amounts of fossil fuel - it takes a half gallon of fossil fuel to produce a bushel of corn.

I have voted to make tough decisions in budgetary times, I've served on two recessionary budgets, my opponent has never served on any a budget committee where there was less money to spend than the year before.

In merging nature and culture the most successful cities combine such universal needs as maintaining or restoring contact with the cycles of nature, with specific, local characteristics.

If you're hanging around with nothing to do and the zoo is closed, come over to the Senate. You'll get the same kind of feeling and you won't have to pay.

Everything depends on a good job - strong families, strong communities, the pursuit of the American dream, and a tax base to support schools for our kids and services for our seniors.

I am a sucker for jackets!

I am just an ordinary person trying to do an ordinary job.

Exploiting people's emotions of fear, envy and anxiety is not hope, it's not change, it's partisanship. We don't need partisanship. We don't need demagoguery, we need solutions.

By 'justice', I understand nothing more than that bond which is necessary to keep the interest of individuals united, without which men would return to their original state of barbarity. All punishments which exceed the necessity of preserving this bond are, in their nature, unjust.

I must confess that I'm not a great reader. At the moment I'm reading my son's 'Stig of the Dump' by Clive King and I've got a plant catalogue on the go.

Cerner has significant growth opportunities. We believe there is leverage with HNA Millennium and in our business model that can grow both our top-line and earnings during 2000 and through the foreseeable part of this decade.

I don't really trust men who claim they are not interested in porn.
