Web-based stimulus preference assessment and reinforcer assessment for videos

The multiple-stimulus-without-replacement preference assessment tool and its predictive validity

This study demonstrates the use of two web-based programs, one to identify video preferences and the other to assess their reinforcing effects. We used the Multiple-Stimulus-Without-Replacement Preference Assessment Tool (MSWO PAT) to identify the video preference hierarchies of seven participants, ages 4-11 years old. We then used a customized reinforcer assessment program that arranged a concurrent-chains preparation with programmed conjugate schedules of reinforcement. Button presses emitted by participants modulated the quality (volume and opacity) of selected videos on a moment-to-moment basis, allowing us to identify the reinforcing effects of the videos in little time. The results showed that the preference assessment had predictive value for five of seven participants. We discuss the MSWO PAT, parameters that may affect the identification of preferences and the use of conjugate schedules to identify reinforcers.

A multiple-stimulus-without-replacement assessment for sexual partners: Test-retest stability

The stability of stimulus preference assessment results is an important consideration when using the identified stimuli in treatments and/or additional experiments. Prior research has demonstrated that the preference hierarchies identified by the multiple stimulus without replacement (MSWO) preference assessment are generally stable over time. This stability has been demonstrated with tangible and edible items, yet the extent to which that stability can be expected for other types of stimuli remains unknown. The current study tested the 2-month stability of the MSWO preference assessment in the context of college students' preferred sexual partners. Adequate stability was shown in most cases, suggesting generality of the stability of preference across tasks, populations, and stimuli.

Adapting Direct Services for Telehealth: A Practical Tutorial

Due to the pandemic brought on by the novel coronavirus (COVID-19), consumers of applied behavior-analytic interventions may be experiencing disrupted access to services. In response to the need for services, behavior analysts and therapists may find themselves treading unchartered waters as they use telehealth to provide direct intervention to consumers. Direct service provision via telehealth extends beyond the bounds of existing telehealth research, which primarily focuses on caregiver training and consultation. In the transition to telehealth, behavior analysts can consider how to adapt an existing evidence base of behavior-analytic strategies from a face-to-face format to intervention via a teleconferencing platform (i.e., Zoom). In this tutorial, we provide practice recommendations, task analyses, and a curated list of Zoom walk-throughs to help behavior analysts construct conceptually systematic learning opportunities in their direct telehealth services. Leveraging teleconferencing features to provide behavior-analytic intervention directly to consumers could spur future research to support these need-inspired practices and guide telehealth applications during and beyond the current pandemic.
