ABSTRACT

The present study examined whether providing echoic prompt to label items oractivities contingent on emission of palilalia was effective in reducing the vocalstereotypy and increasing tacts and mands as appropriate vocal responses in a9-year old male with autism. A reversal design was used. During the baseline, thepalilalia was ignored and mands and tacts were reinforced. During the treatmentcondition, the experimenter presented echoic prompts to tact actions and objectsfollowing the emission of palialia. The results showed that the treatment didn’tproduced a significant decrease in the levels of occurrence of palilalia. However,the frequencies of tacts and mands were increased during the treatment conditions.
