Jon Hakun

Postdoctoral scholar 

******************************************************************************************************************************

Jon earned his PhD in psychology from Michigan State University. His dissertation focused cognitive control and working memory, and was completed under the direction 

of Dr. Susan Ravizza. Jon’s specific project explored the influence of visual working memory representation over the control of attention. As a post-doc in our lab, Jon is 

investigating the influence of aging on cognitive control. Primarily, he is working on a study of cognitive flexibility, relating longitudinal changes in BOLD fMRI during tasking 

switching to measures of structural and functional neural integrity.
