RecruitingDevice studyNeurobehavioral Signatures of Sign- and Goal-Tracking in Emerging Adults: Translation of a Preclinical ModelThis study seeks to understand individual differences in personality, brain function, and behavior. Study hypothesis: \- A stronger sign-tracking bias will be associated with a bottom-up processing style characterized by less adaptive attentional- and impulse-control as well as hyperactive reward processing, whereas a stronger goal-tracking bias will be associated with a top-down processing style characterized by strong attentional- and impulse-control as well as normative reward processing.
