  Title Word length and the structure of short-term memory Type Journal Article
  Year 1975 Publication Journal of Verbal Learning and Verbal Behavior Abbreviated Journal Journal of Verbal Learning and Verbal Behavior  
  Volume 14 Issue 6 Pages 575-589  
  Keywords Immediate memory span; Word length  
  Abstract A number of experiments explored the hypothesis that immediate memory span is not constant, but varies with the length of the words to be recalled. Results showed: (1) Memory span is inversely related to word length across a wide range of materials; (2) When number of syllables and number of phonemes are held constant, words of short temporal duration are better recalled than words of long duration; (3) Span could be predicted on the basis of the number of words which the subject can read in approximately 2 sec; (4) When articulation is suppressed by requiring the subject to articulate an irrelevant sound, the word length effect disappears with visual presentation, but remains when presentation is auditory. The results are interpreted in terms of a phonemically-based store of limited temporal capacity, which may function as an output buffer for speech production, and as a supplement to a more central working memory system.
