Performance on visual or auditory perceptual tasks such
as letter recognition, object recognition, and pattern
discrimination can be dramatically improved with
training or practice. This project studies the
nature of efficient
training, and how brain process are changed by training.
This research project will lead to an increased
understanding of the
conditions and methods of perceptual training that may
assist in assessment of perceptual deficits and
remediation.
This
project has been supported previously by the National
Institute of Mental Health and the National Science
Foundation and is currently supported by the National
Eye Institute.
