Peripheral Vision Training Study

University of Alabama at Birmingham30 enrolled

Overview

This study will train participants (young people and older adults) to do a visual task, and will assess whether this results in changes in behavioral assessments. In some participants, we will be also testing whether MRI measures (cortical thickness, functional connectivity) change with training.
