Abstract
|
|
|
This study investigated the effects of Transitive Conditioned Motivating Operation(CMO-T) on ‘specific response forms of mands’ in a toddler with language delays. A 3-year-old, male with language delays beyond a year in his development stages served as the participant of this study. The multiple probe design across behaviors was used in the experiment. Additionally, transfer-of-function procedures were utilized as combined intervention for effectiveness of the intervention. Preference assessment was performed to manipulate settings for CMO-T and 3 tasks were selected for the intervention. The sequence of the tasks were interrupted and the items which were essential for
termination of the tasks and highly preferred were omitted by the instructor intentionally. The missing items or informations were provided when the participant emitted appropriate mands. Results indicated that acquisition of mands had increased during the intervention across all three CMO-T tasks and maintained after the intervention. They also suggested that mand could be utilized as a independent variable for intraverbal when it functioned as ‘specific response forms of mands’.
