Visual Attention, Object Recognition, and Eye Movements in Healthy Volunteers
United States40 participantsStarted 2026-08-18
Plain-language summary
Background:
Vision is vital for many of our daily activities. Researchers want to learn more about how we aim our eyes (that is, what images, such as faces, immediately attract our attention) and how we direct our attention (that is, what we see and what we ignore).
Objective:
To study how healthy adults process and respond to visual images.
Eligibility:
Healthy people aged 18 years with no vision problems.
Design:
Participants will have 5 to 10 clinic visits over 2 to 4 months. Some participants may have up to 25 visits. Each visit lasts about 1 hour.
Participants will be screened. They will answer questions about their medical and eye history. They will have a standard eye exam; eye drops will be used to dilate the pupils. (They may skip this exam if they have had an eye exam at the NIH within the past year.)
Participants will perform eye movement tests. They will sit in front of a computer and view images that appear on the screen. They may be asked to respond to what they see by speaking, moving their hands, looking in a certain direction, or pushing a button. Their eye movements will be tracked.
For some tests, participants heads may be held steady using a chinrest and head strap. For some tests, they may wear a cap fitted with cameras that use invisible lights in front of their eyes.

* INCLUSION CRITERIA:
In order to be eligible to participate in this study, an individual must meet all of the following criteria:
* Stated willingness to comply with all study procedures and actively pay attention to visual stimuli and respond as appropriate.
* Participant has visual acuity of 20/25 or better in both eyes.
* Participant must be 18 years old or older.
* Participant must understand and be willing to sign a written informed consent document.
EXCLUSION CRITERIA:
An individual who meets any of the following criteria will be excluded from participation in this study:
* Participant has an ocular, visual, or oculomotor problem that in the opinion of the Principal Investigator (PI) and/or clinical associate investigator would interfere with the participant s normal eye movements, visual perception, or required tasks.
* Participant has a history of eye patching (amblyopia or lazy eye).
* Participant has a non-ocular condition (e.g., neuropsychological conditions) that in the opinion of the PI and/or clinical associate investigator would interfere with the participant s normal eye movements or visual perception.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Measurement of significant deviations in the trajectories or latencies of saccadic eye movements that are specific to basic features of socially relevant visual stimuli.
