In this review, we summarized and meta-analyzed 35 single-case intervention studies that involved the use of multiple schedules of reinforcement with 78 individuals with intellectual and developmental disabilities. Based on Tau-U calculations, multiple schedules of reinforcement produced an overall large effect for appropriate communicative…
