329 nouns of A-frequency were rated on a 7-point scale for concreteness, specificity, and pronunciability by three different groups of Ss. A fourth group was used to scale the words for m by a 30-sec production method. Means of each word for s, c, and m are presented. The interrelationships among all parameters and the second-order partial correlations between m, s, c and number of letters (L) are discussed. {\textcopyright} 1966 Academic Press Inc.
