What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers at Brown University are studying perceptual learning: how practice with visual tasks changes what people can detect or tell apart. Healthy adults aged 18 to 60 with normal or corrected-to-normal vision complete behavioral visual exercises while the team records brain signals with neuroimaging. The goal is to map links between training-related performance changes and brain activity.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Visual training, where participants practice detecting or telling apart visual stimuli
What this could lead to
If the approach works, it could help explain how practice rewires the brain and inform training programs for vision or rehabilitation.
What could go wrong
This is basic science with healthy volunteers, so it may not produce a clear brain signal or any practical application. Participants spend time on repetitive visual tasks with no personal benefit.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 400 people

The number the study aims to enrol. It can still change while the study runs.

Started

Feb 2025

Expected to finish

May 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 60 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Ages 18 - 60, * Normal or corrected-to-normal vision Exclusion Criteria: * Eye disorders (cataracts, age related macular degeneration, diabetic retinopathy, glaucoma) * Drug use (psychoactive drugs, neuroleptic medications, prescription medications that might affect cognitive and motor performance) * Sleep disorders (sleep apnea, insomnia) * Magnetically or mechanically activated implants (such as cardiac pacemakers) * clips on blood vessels in the brain * intrauterine devices * dentures * pregnancy
