ABSTRACT
ABOUT SPACED PRACTICE For about a hundred years aer Ebbinghaus discovered that he could remember a list of nonsense syllables better if he took a break once in a while, the kinds of things learned and the temporal and sequential units whose spacing were explored were quite limited. e items were primarily words or nonsense syllables, and the units that were spaced were whole groups of items. So, for example, a given nonsense syllable never followed itself very soon, at least in a way that was planned or analyzed so as to reveal the almost null eects of immediate repetition.
