Attention to a position in space or to an attribute such
as color can improve the ability to process information. This
project investigates two functions of attention - the
ability to amplify visual or auditory inputs through
attention, and the
ability to filter out non-target inputs.
Understanding attention in normal adults may help us
understand the role of
attention in development and the ways that attention
deficits impact information processing.
This project is currently supported by the National Institutes of Mental Health.
This
project has been supported by the Air Force Office of
Scientific Research, Life Sciences.
