They will administer a battery of high-level vision tests to probe psychophysically visual functions, such as recognition of objects, faces and scenes. Other, lower-level tests will help the team determine whether subjects have better visual acuity, contrast sensitivity, visual fields, color vision and reading ability.
The patients will also be trained in techniques of perceptual learning to make the best use of the devices; statistical learning tools built into the devices will adapt automatically to the needs of the patients. Bosco Tjan of the USC College Psychology Department, Susana Chung from the University of Houston, and Eli Peli from Harvard Medical School will lead that effort.
Other USC faculty working on the NIH study include Irving Biederman of the College, who is an expert in object, face, and scene recognition; Zhong-Lin Lu of the College and Viterbi School, who specializes in motion perception and perceptual learning; and AMD specialist Dr. Mark Humayun, who holds joint appointments in the Keck School of Medicine of USC Department of Ophthalmology and the Viterbi School of Engineering.
