Catechol-O-methyltransferase (COMT) Genotype Affects Age-Related Changes in Plasticity in Working Memory: A Pilot Study

<table>Behavioral plasticity (level attained in each session) in younger (diamonds) and older adults (squares) as a function of genotype (dotted line represents Val/Val; continuous line represents any Met). Error bars reflect standard errors of the mean.
