Domain‐specific impulsivity in school‐age children [PDF]
Developmental Science, 2013 AbstractImpulsivity is a salient individual difference in children with well‐established predictive validity for life outcomes. The current investigation proposes that impulsive behaviors vary systematically by domain. In a series of studies with ethnically and socioeconomically diverse samples of middle school students, we find that schoolwork‐related
