Using video modeling with voiceover instruction plus feedback to train implementation of stimulus preference assessments

Behavior analysts frequently use stimulus preference assessments to identify putative reinforcers for consumers with autism spectrum disorder. The current study evaluated the effect of video modeling with voiceover instruction and on-screen text (VMVOT) and performance feedback to train staff to implement the multiple-stimulus-without-replacement, paired-stimulus, and single-stimulus preference assessments. Generalization probes with a larger stimulus array and with an actual consumer were conducted. The results indicated that VMVOT may be a useful prelude to in-vivo training approaches, as all staff mastered the preference assessments and demonstrated high levels of generalized responding. This outcome is discussed in light of previous staff training studies and avenues for future research.
