Warm-ups, and the Von Restorff Effect are also processes that retard forgetting.
The Warm-up Effect is yet another antidote to the forgetting curve. The effect is not unlike warming up for an athletic activity.
It is an excellent reason to have a review at the beginning of each new lesson!
And last but not least is the Von Restorff Effect. Please quickly read and try to remember the following list of words:
talk, tree, fish, cake, monumental, pea, cup, dog, ran, jaw, cool, dumb, make, ship, fight, ring, and zip.
You will probably remember talk and zip because of the Primacy and Recency effects; but you would also typically remember monumental because it stands out from the rest.
That is the Von Restorff Effect and can be used to good advantage for important things we want someone to remember. For example we can exaggerate it, make it bizarre, make it unique, bold and underline it, and you name it!
