Assessment of anomia: Improving efficiency and utility using item response theory

Study Description:
The purpose of this research study is to develop a standard scale for measuring the ability to name things in people who have aphasia. We will use this information to develop tests that are clinically useful and scientifically sound, and to develop a new computer adaptive test of naming. The ultimate goal of this study is to provide speech-language pathologists with better tools for evaluating the naming abilities of persons with aphasia.
