The method of Glaze was used to scale 320 words and paralogs for meaningfulness. One hundred Ss provided data from which three such measures were derived. Employing the most conventional of these measures (percentage of Ss responding in less than 2.5 sec) to select the items to be learned, a validating study demonstrated the usual relationship between association value and speed of learning. Other investigations have employed the materials successfully for purposes of control when the main interest of the experiment was in some other problem. {\textcopyright} 1967 Academic Press Inc.
