PERCEPTUAL LEARNING
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 ahs been
supported previously by the National Institute of
Mental Health and the National Science Foundation
and is currently supported by the National Eye
Institute.
