The goal of this clinical trial is to learn if a computerized eye-tracking training program can improve mental health and thinking skills in older adults. The main questions it aims to answer are whether eye-tracking training can lower depressive and anxiety symptoms in older adults, and whether it can improve their ability to control impulses and pay attention.

Researchers will compare older adults who receive eye-tracking training to older adults on a waitlist to see if eye-tracking training leads to greater improvements in mood and thinking skills.

Researchers will randomly assign participants into the experimental group or the waitlist control group. Participants in the experimental group will take part in eye-tracking training three times a week for 18 sessions, over about 1.5 months. Before and after training, participants will answer questions about their mood and take tests of memory, attention, and impulse control. Older adults on the waitlist will complete the same tests but will not receive training until after the study period; they will be offered the same training once their waiting period ends.
