In this study, researchers at
Harvard University found that adolescents may
not benefit from high stakes to the same degree adults do—a behavioral profile
that may be constrained by ongoing maturation of corticostriatal connectivity.
The researchers of this study propose that late development of corticostriatal
connectivity sets the stage for optimal goal-directed behavior. used functional
magnetic resonance imaging (fMRI), which measures brain activity by detecting
changes linked to blood flow. Lead researcher Katie Insel said older
adolescents were able to boost their performance when the stakes were high. However, younger adolescents performed
similarly for low and high stakes outcomes.
