The multiple stimulus without replacement (MSWO) preference assessment is commonly used to identify potential reinforcers. In this arrangement, individuals can choose the order in which they consume edibles or activities. The item selected first is often designated the highest preferred, and the item selected last is often designated the least preferred. Scattered reports suggest that some individuals may save the best for last in an MSWO. Despite these reports, few systematic evaluations of “saving the best for last” in the MSWO have been conducted. We examined this phenomenon using an MSWO and progressive‐ratio‐reinforcer assessment. Evidence of “saving the best for last” was obtained for one of four individuals across assessments involving edibles and leisure activities, respectively.

COVID-19 is a disease caused by the virus, SARS-CoV-2, and it can affect individuals differently. Some people may experience mild symptoms while others may experience severe illness or death. Vaccines that are authorized to protect against COVID-19 help the human body develop immunity to SARS-CoV-2 and reduce the risk of COVID-19 and its potentially serious complications. We evaluated the effects of graduated exposure and differential reinforcement to teach individuals with autism to comply with the administration of a COVID-19 vaccine. All three participants had a history of engaging in challenging behavior during previous vaccination procedures. Following the intervention, all participants successfully received two doses of a COVID-19 vaccine. The results of this study support previous research on graduated exposure and differential reinforcement as a treatment for increasing compliance with medical procedures for individuals with autism.
