This study compared 2 units of analysis for assessing acquisition mastery during sight word instruction for 3 participants. The unit of analysis refers to the specific performances that criteria are applied to, either sets of stimuli or individual operants. In the Set Analysis condition, we applied the acquisition-performance criterion to the…

We compared the effects of different "mastery" criteria and doses on the acquisition and maintenance of sight words for 4 second graders with and without disabilities. First, we replicated Set Analysis and Operant Analysis conditions where participants were taught sight words in 20-trial (4 operants, 5 opportunities) sessions.…

Instructors assess the acquisition of new skills by delivering blocks of trials containing multiple operants. Mastery is evaluated as percentage correct across all operants in the block. The purpose of the current study was to investigate this traditional mastery criterion arrangement compared to an analysis of mastery at the level of individual…

The purpose of this study was to examine utility of a brief experimental analysis (BEA) in determining effective sight word interventions for a student with a history of difficulty with acquiring sight word recognition. Ten interventions were compared in a BEA. Following the BEA, an extended analysis was conducted that compared the two most…
