The research assessing the effectiveness of mand training with individuals with autism spectrum disorder (ASD) focused on teaching vocal mands for preferred items. However, individuals diagnosed with ASD frequently utilize alternative modes of communications. Other common mode of communications employed by children with ASD involves a picture exchange communication system (PECS). Mand training with peers is an important aspect of intervention for individuals with ASD because it fosters opportunities for additional interactions for the individual with others that could help establish friendships. It is also important critical to teach the child to engage in peer-directed mands rather than engaging in other less socially acceptable ways of obtaining the item.
“The ideal outcome of peer-directed mand training is for a child to approach a peer who is currently consuming a preferred item and mand for access to that item in the absence of adult prompts” (Kodak, Paden, & Dickes, 2012). Prior studies on peer-directed man training have failed to measure whether newly acquired mands extend beyond the treatment context. One example of this is with Paden and colleague’s previous research. They evaluated differential reinforcement of alternative behavior along with prompting to increase peer-directed mands using PECS with two boys diagnosed with Autism. The results of their study indicated that both boys engaged in high rates of peer-directed mands during treatment, and a portion of the peer-directed mands resulted in subsequent social interactions. The experiment performed in this study by Kodak, Paden, and Dickes wished to replicate the findings of Paden and colleagues by evaluating the effects o...

...of independent mands during the first phase. However, on the SCC rechart there are no trends for either independent or prompted mands during the first phase. In the second phase there is variability in both independent and prompted mands. In the original chart, during the second phase, there is a slight increasing trend in prompted mands while on the SCC rechart there is no trend at all.
In conclusion, there were several differences and similarities between the two charts. The Standard Celeration Chart shows an increase and decrease in the data points more accurately than the other chart. An expirimentor is able to see clearly how the behavior is changing daily.
