ABSTRACT

The purpose of this study was to determine the efficacy of Transitive Conditioned MotivatingOperation(CMO-T) training to mand in a child with language delays over a year. A multiple-probedesign across behaviors was used for the study. The authors designed the setting for examination which isapplicable to CMO-T training. Once antecedent stimulus was presented, when the participant’s responsewas correct, he was provided by the object he manded. However, when he showed incorrect response,echoic prompts were provided, then he got the object he manded when he used echoic-mand. Three tasksfor the intervention were chosen for CMO-T training; puzzles, pegs and threading beads. The authorsexamined alteration in the participant’s mand by applying CMO-T training to the tasks they have chosenfor the intervention. Results indicated that the participant’s mand showed an increase in all three tasksduring intervention phase, and he could use mand without any prompts during maintenance phase. It issignificant that the result data of this study suggests detailed CMO-T training for establishing mandskills.
