Abstract
Nonsense syllables show greater variability than words as "learning" material with unpracticed S's and less variability if the S's are trained. A relatively small amount of training is needed for this attainment. Economy of effort is the only reason for using the syllables, and the writer concludes that Ebbinghaus' assumptions as to the utility of the syllables in "memory" experiments are "justified neither in fact nor in theory."
