In collaboration with Laurence Steinberg of Temple University and grant funding from the Jacobs Foundation, Decision-Making in Everyday Life was an assessment of judgment, decision-making, and psychosocial development from over 350 participants in Durham and Winston-Salem, North Carolina. The measures used were also being administered in China, Colombia, Cyprus, India, Italy, Jordan, Kenya, the Philippines, Sweden, and Thailand. The assessment included questions about several aspects of development that affect the choices young people make, including choices to engage in risky and antisocial behavior. These aspects of development included impulsivity, foresight, sensation-seeking, planning, and reward salience.
The results had important policy implications with respect to issues such as making judgments about the criminal responsibility of juvenile offenders and understanding the age at which individuals develop the capacities to be held fully responsible for their actions.
