N2  - <p><b>Abstract</b> Temporal stability, discriminant validity, and factor structure of an array of performance measures of impulsivity was assessed within samples of normal (<i>N</i>= 48) and behaviorally disordered children (<i>N</i>= 88) ages 6-16 (126 M, 10 F; mean age = 10.57 years; <i>SD</i>= 2.13). Using a relatively conservative standard for adequate temporal stability, 31% of the variables derived from these measures met criterion. Of these, 83% were able to discriminate groups after partialling out the effects of intellectual aptitude and age. Factor analysis yielded a two‐factor solution interpreted as representing cognitive (inhibitory control) and motivational (insensitivity to punishment/nonreward) components of impulsivity.</p><p />
