Reading Difficulty in Adults with Intellectual Disabilities: Analysis with a Hierarchical Latent Trait Model

12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

Abstract

In prior work, adults with intellectual disabilities answered comprehension questions after reading texts. We apply a latent trait model to this data to infer the intrinsic difficulty of texts for the participant group. We then analyze the correlation between grade levels predicted by an automatic readability assessment tool and the inferred text difficulty.
