A group of subjects was made familiar with a small inventory of nonsense syllables and later learned various rules of organization, each set of rules progressively limiting the syllables which could appear. They then tried to memorize passages of syllables chosen in conformity with the rules learned previously. Organizational arrangements employed ranged from random order (high avg. rate of information) to high organization (low avg. rate of information). More syllables are correctly recalled from a passage with a lower avg. rate of information than from a passage with a higher avg. rate of information. Up to a certain degree of organization, between 2 and 1.5 bits/syllable, the amt. of information learned was constant. Beyond a certain degree of organization, about 1.5 bits/syllable, the relationship between the quantity of material recalled by the subjects and the avg. rate of information contained in that material tended to become disproportionate. Although an increasingly greater number of syllables was correctly recalled, the total amt of information contained in the syllables was smaller than in the less organized passages. Up to a certain degree of organization, the quantity of material a subject can recall can be predicted from a knowledge of the avg. rate of information of the given passage and the subject''s level of ability as measured in a passage having a different avg. rate of information.
