Trial Summary

What is the purpose of this trial?

The purpose of this study is to investigate how our performance changes after our perceptual system is trained in a certain way ("perceptual learning"). In addition, investigators are interested in identifying and characterizing relationships between such changes and neuroimaging signals recorded from the human brain.

Eligibility Criteria

This trial is for individuals aged 18-60 with normal or corrected-to-normal vision. It's not suitable for those with magnetic or mechanical implants, brain vessel clips, IUDs, dentures, pregnant women, people with eye disorders like cataracts or glaucoma, drug users affecting cognition and motor skills, or those with sleep disorders.

Inclusion Criteria

My vision is normal or corrected to normal.

Exclusion Criteria

Magnetically or mechanically activated implants (such as cardiac pacemakers)

Clips on blood vessels in the brain

Intrauterine devices

Timeline

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Training

Participants undergo visual perceptual learning using artificial stimuli such as Gabor patches and natural scenes

2 weeks

Follow-up

Participants are monitored for changes in visual task performance and neuroimaging signals after training

4 weeks

Treatment Details

Trial Overview The study examines how training our perception affects performance and identifies links between these changes and brain signals. Participants will undergo perceptual learning tasks while their neuroimaging signals are recorded.
