Performance on attention tasks by FAS-FAE and ADHD status.

ADHD = attention deficit hyperactivity disorder; FAE = fetal alcohol effect; FAS = fetal alcohol syndrome; WISC-R = Wechsler Intelligence Scale for Children, Revised.

NOTE: The bars represent the variation away from the average score (i.e., the z-score) so that the bigger the bar, the more the group differs from “normal.”
