For this study, researchers from UGA's Neuropsychology and Memory Assessment Laboratory and Vision Sciences Laboratory collaborated to use a method based on measuring processing speed through sight.

However, visual response times and visual acuity did not have a significant correlation (r = 0.273) or contrast sensitivity (r = 0.273). There were some limitations to this study.
