Thanks for visiting CogUSC or the Unified Studies of Cognition website!

CogUSC research is designed to address several important current national needs in cognitive aging. To meet these needs, we currently collect new information based on theories about the multidimensional aspects of cognitive aging. This is indicated by important statements such as:

"We echo the NRC Committee's recommendation for a large-scale multi-site population based longitudinal study of cognitive aging to better understand the needs of an increasing proportion of the U.S. population."

Recent cognitive aging overviews have highlighted this multidimensionality with findings that general cognitive losses over age are due to declines in the specific factors of (1) explicit memory, (2) general slowing, (3) inhibition of attention, and (4) sensory, motoric, and physical deficits. Other overviews emphasize concepts of executive functioning, adaptation and optimization, questions based on expertise, and sources of knowledge.
