Abstract
Multiple stimulus without replacement (MSWO) preference assessments have been demonstrated to effectively identify reinforcers
for individuals with severe to profound disabilities, but it may be possible to make the procedures more efficient by decreasing
the number of array presentations. This investigation presents one case study that compared single-, three-, and five-session
MSWO formats to determine if reinforcers could be reliably identified with all three formats for one student with pervasive
developmental disability not otherwise specified (PDD-NOS). Using a concurrent-operants design embedded in a reversal design,
subsequent reinforcer assessments indicated that a reinforcer was identified with each assessment format. Directions for future
research and procedural limitations will be discussed.
