A visual activity schedule (VAS) is an evidence-based intervention that can assist individuals to follow a routine, see what is coming next, reduce dependence on others, and aid in transitions. A VAS is a sequence of visuals (photographs, avatars, line drawings, etc.) that can be used to show the user what they are to do in a specific order. A VAS acts as a template for the task the user is supposed to accomplish. Visual schedules can be beneficial for a wide range of users; they have been seen to be especially effective when used with individuals with disabilities, autism spectrum disorder (ASD) in particular. The purpose of this research proposal is to determine if a visual activity schedule with icons that iconically looks like the respondent increase performance outcomes. Dependent variables of two participants were measured in the context of an alternating treatments design. One treatment used a generic VAS, and the alternate used an individualized VAS that iconically resembled the respondent. The research measured social validity by interviewing the participants, using components of a paired stimulus preference assessment, and a teacher survey.
