A single-participant multiple probe design across participants was used to evaluate the effectiveness of verbal rehearsal and graduated guidance to teach youth who were blind how to cross the street. This study replicated intervention procedures across settings along with the staggered entry of participants. Individuals learned to cross one or two…

The regression discontinuity design (RDD) has the potential to yield findings with causal validity approaching that of the randomized controlled trial (RCT).
