Interventions

• Covert Spatial Attention — BEHAVIORAL
  During behavioral sessions, subjects will sit in a dark room and view a video monitor placed at the minimum of 57 cm distance away from the subject. Staff will be present throughout all the testing to assist the subject and monitor equipment that is used for tracking their eye position. Subjects will be asked to maintain their heads in a stable position of rest in order to insure accurate tracking of their eye position. To stabilize their head, subjects will either use a "chin rest" in which they position their chin on a soft pad mounted in front of a video screen, or they may use a "bite bar."
