Visual Test Can Help Identify Early Signs of Cognitive Impairment

University of Georgia researchers have developed a simple technique to measure an individual’s visual processing speed — the speed at which an individual can comprehend visual information — in order to identify whether or not they may have cognitive issues.

The recent study, published in the journal Archives of Clinical Neuropsychology, focuses on using a simple test of visual flicker to evaluate an individual’s level of executive cognitive abilities, such as shifting attention between different tasks, planning or organizing and problem solving.

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. Catherine Mewborn, a doctoral candidate in UGA’s Franklin College of Arts and Sciences department of psychology, led the study.
