Official title: Attention-enhanced perceptual learning in neurotypicals and cortical blindness
Funded at University of Rochester · NIH-11446726 · Data updated 2026-11-12
A stroke-related vision loss condition is targeted with a training program that uses attention-driven exercises to improve visual perception.

Who could benefit from this research
✓Could help
Adults 21 years and older with unilateral cortical blindness due to stroke, in subacute or chronic stages, who can participate in visual training tasks.
✕Less likely to help
Individuals without cortical blindness or those unable to participate in training tasks may not benefit.
What this research studies
This project helps people who have lost part of their vision after a stroke by using specific training tasks that leverage attention to improve perception in the damaged visual areas. The approach builds on previous findings that perceptual training can restore some vision and that combining different attention types may boost recovery. The study compares neurotypical participants and stroke patients to understand how these methods work in real-life patients and how timing after stroke affects outcomes. If successful, the training could become a practical, patient-friendly option to enhance daily vision after cortical blindness.
Why it matters
Potential benefit: If the approach succeeds, patients could regain usable vision in impaired areas, improving daily activities and independence.
How similar studies have gone: Previous work in both neurotypical individuals and stroke patients shows promise for perceptual training to improve vision, with ongoing refinement.
