The SUN Test of Vision: Investigation in Healthy Volunteers and Comparison to the MULES

Rapid automatized naming (RAN) tests have been widely used in evaluating various neurological conditions. These tests requirequick and accurate identification of numbers and pictures, thus assessing brain pathways involved in vision, memory, language, and attention. The MULES (Mobile Universal Lexicon Evaluation System), an established picture-naming RAN test, has been effective in identifying concussion, multiple sclerosis, and Parkinson's disease. To complement the MULES, we have developed a novel number-based RAN test called the SUN (Staggered Uneven Number) test. This study introduces and determines baseline values for the SUN and compares the SUN to the MULES.
