title: Tangibles, Pictures, and Verbal Descriptions: Which Should Be Used in Choice Presentations?
abstract: Little research has examined how stimulus modalities influence choice responding. Should choice alternatives be presented using tangibles, pictures, or verbal descriptions? How should caregivers decide which modality to use? We have completed several studies to examine how discrimination skills, as measured by the Assessment of Basic Learning Abilities test, interact with choice stimulus modalities to influence responding. Our results suggest that for persons with developmental disabilities with limited or no communication skills, the ability to make simple visual, visual matching to sample, and auditory-visual discriminations should be the prime determinant of stimulus modalities in choice presentation and preference assessment.
