A Comparison Of A Topography-Based Language System And A Selection-Based Language System, Carl Sundberg
Masters Theses
This study examined whether it was easier for developmentally disabled individuals to acquire a topography-based or a selection-based language system. Four moderately and mildly mentally retarded adults served as subjects. Each of the subjects was taught to tact an object by either pointing to its corresponding symbol (with the selection-based paradigm) or making the corresponding sign (with the topography-based system). They were then taught an intraverbal relation by either selecting the symbol, or making the sign which corresponded to an auditory stimulus. Finally, the subjects were tested for the emergence of stimulus equivalence classes. Each subject was trained and tested …

The Acquisition Of Spelling By Developmentally Disabled Adults: An Examination Of Some Variations Of The Look-Cover-Write-Check Cycle, Mark Stafford
Masters Theses
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 …
