Fractionating the Impulsivity Construct in Adolescence.

The article focuses on fractionating the impulsive behavior of adolescents. It mentions that adolescent impulsivity can manifest in a range of sub-optimal behaviors including the use of alcohol, nicotine, or illicit substance, poor performance on laboratory assays of impulse control, and attention deficit hyperactivity disorder (ADHD) symptoms. Moreover, insights into the etiology of maladaptive impulsive behaviors yield from the understanding of neural correlates of impulsivity subtypes.
