Using Pictures Depicting App Icons to Conduct an MSWO Preference Assessment on a Tablet Device.

Identifying preferred content on tablet devices may be important when using such devices in programming. This study included six adults with disabilities and examined using laminated picture cards depicting application (app) icons to conduct multiple-stimulus without replacement (MSWO) preference assessments of iPad content. Following identification of preference hierarchies, we conducted reinforcer assessments to validate preference assessment results by demonstrating that selected apps functioned as reinforcers. We identified preference hierarchies for all participants, and the highest preferred app functioned as a reinforcer for a vocational task in five out of six participants' reinforcer assessments.
