Five developmentally disabled adults were taught to spell groups of five words using the look-over-write-check cycle, in which the subject looks at the word, covers it, writes the word, then looks at the word again to check the accuracy of spelling. Four variations of this procedure were used with each of the subjects including requiring the subjects to spell the words out loud in the "look" component. The results showed that the subjects required fewer sessions and fewer trials to spell the five words when the out loud requirement was in effect. Approximations generated as the subjects learned to spell indicated that intraverbal behavior played a major role in spelling with these subjects. Suggestions for future research and spelling training are made.
