My research consists of examining the construct of executive function/executive control and fluid abilities generally. My primary interest is in the developmental pattern seen in executive function from childhood to older adulthood and how this behavioral pattern relates to anatomical changes in the frontal lobes. I am also interested in improving the psychometric properties of tests of executive function, particularly the Tower of London. My other research interests involve how executive functions measures relate to real-world activities such as driving and decision making. I am also interested in whether or not interventions such as meditation could enhance executive function performance.
