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.

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".

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.

An American Idol is someone that has all the qualities that America thinks is positive, attractive and alluring.

The world has changed. It's not enough to simply buy American; we have to sell American, sell our products and goods and services throughout this world.

I always wanted to be honest with myself and to those who have had faith in me.

Opportunities don't happen. You create them.

It is not knowledge but the act of learning not possession but the act of getting there which grants the greatest enjoyment.

The extent to which not just state legislatures but the Congress of the United States are now run by large corporate special interests is beyond mere recognition as fact. The takeover is complete.

We must dare to rise above the obstacles on our path.

I was diagnosed with everything from schizophrenia to multiple personality disorder.

They made it to the middle class, my dad working as a bartender and my mother as a cashier and a maid. I didn't inherit any money from them. But I inherited something far better - the real opportunity to accomplish my dreams.

I had wanted to be a regular character on a series for a while. 'The Brady Bunch' was an answer to a prayer.

My fans and followers are so amazing.

Men and women are immigrants in each other's worlds.

To secure peace is to prepare for war.

Patriotism is a kind of religion; it is the egg from which wars are hatched.

The Japanese, despite the trade deficit and their ability to build fabulous automobiles, still think that a guy in a monster suit is all that is needed for a monster movie.

I've no idea what Eddie Irvine's orders are, but he's following them superlatively well.

If today is anything like the typical day of the past 3 years, three American soldiers will die in Iraq or Afghanistan, the Taliban will get a little stronger in Afghanistan and the civil war will continue to be enhanced in Iraq.

If strong economic conditions can partially reverse supply-side damage after it has occurred, then policymakers may want to aim at being more accommodative during recoveries than would be called for under the traditional view that supply is largely independent of demand.

I realise how important it is to use the time I have. I respect people who want to do that by watching television. I happen to want to read books. But I know I can't read all the books or watch all the movies in one lifetime.

Nobility is expensive, nonproductive, and parasitic, siphoning away too much of society’s energy to satisfy its frivolous cravings.

Realistic novels simply pretend that the rules of their invented worlds are identical to the rules of actual life, but that's a ruse.

A lion doesn't concern himself with the opinion of a sheep.

I'm just a hired actor who was hired for a particular job, but I think one of the joys of reading the script was the way that the personal and the global are woven together.
