Evaluating preference assessments for use in the general education population.

This study compared the effectiveness of a multiple-stimulus-without-replacement (MSWO) preference assessment and teacher preference ranking in identifying reinforcers for use in a general education setting with typically developing elementary-school children. The mean number of digits correctly answered was greater in the MSWO-selected reward and the teacher-selected reward conditions relative to the no-reward condition for 2 of the 4 participants, but there were no differences between the MSWO-selected and teacher-selected reward conditions for any participant.
