'This study seeks to understand individual differences in personality, brain function, and behavior.\n\nStudy hypothesis:\n\n\\- A stronger sign-tracking bias will be associated with a bottom-up

processing style characterized by strong attentional- and impulse-control as well as normative reward processing.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '20 Years',
