Stimulus preference assessment, reinforcer assessment, technology, videos, autism


Stimulus preference assessments and reinforcer assessments are integral components of positive reinforcement-based interventions. Web-based brief multiple-stimulus without replacement (MSWO) preference assessments have recently been shown to be effective in identifying preference hierarchies for videos (Curiel, Curiel, Li, Deochand, & Poling, 2018). The purpose of the current studies was to replicate Curiel et al.’s web-based MSWO assessment and assess the reinforcing function of the highest and lowest identified stimuli using novel web-based reinforcer assessments. Study 1 employed single-operant arrangements (SOAs) and Study 2 employed concurrent-operants arrangements (COAs) to assess the absolute and relative reinforcing function of the identified stimuli, respectively. The web-based MSWO was effective in identifying stimulus preferences hierarchies in both studies. Furthermore, the highest-preferred stimuli functioned as reinforcers in both arrangements. The findings, limitations, and areas of future research are discussed.
