The group is too small and there for cannot be generalized to the rest of the population. We are given no details other than gender, age, problem behaviors, and diagnosis. While these details are good they do not show the reader if these four students are an accurate representation of the population that is being studied. It was presented as a group design but, the basis of the authors claims were based heavily on comparison of a date of single subject; Jim. The authors conveniently neglected to examine the behavior of the students whose behavior did not support their claims (75% of the participants) as closely as they did for the one student who did. I believe that it may be difficult to try to facilitate the results of this study in another setting like a school or a hospital. In other applied settings there are a great deal more people that need to be attended to. While I agree that replacement language is a socially important skill to teach, people like teachers and doctors may not have the time available to provide attention or assistance reinforcement as effectively as the administrator in the study. I am curious to see what kinds of effects this study would produce with other replacement behaviors that are non-verbal across a larger subject group. While the research design was very clear and concise and the treatment integrity was great. The authors themselves stated that several of their claims needed to be researched further. If there is no other research that supports their claims and the subject pool is small, then there is not enough evidence to support their hypothesis or
