We evaluated the effects of three different methods of denying access to requested high-preference activities on escalating problem behavior. Functional analysis and response class hierarchy (RCH) assessment results indicated that 4 topographies of problem behaviors displayed by a 13-year-old boy with high-functioning autism constituted an RCH…

This investigation compared the acceptability of three methods for assessing reading (i.e., norm-referenced assessment, curriculum-based assessment, brief experimental analysis), and explored how a new assessment methodology can gain acceptance as a useful and appropriate approach. Given that brief experimental analysis is a relatively new…
