Abstract

Careful design of images of multiple-choice tasks in aphasia assessment is critical to assessment validity. An objective way to evaluate multiple-choice image design is to track eye movements as individuals view sets of images without verbal stimuli. The degree of disproportionate visual attention across images indicates a greater risk to validity of test items. Nineteen adults’ eye movements were recorded as they looked at 64 image sets: 22 sets with well designed physical and semantic stimulus properties, 22 sets of clipart images and 20 sets of images from published aphasia tests. Variation of disproportionate looking among image types is discussed.
