The persistence of cognitive deficits in remitted and unremitted ADHD: a case for the state-independence of response inhibition.
Bottom Line: Of this sample, 130 (73%) were reascertained.Response inhibition, working memory, and response variability were assessed both in childhood (baseline) and adolescence (follow-up) and were compared with age-matched controls (40 children and 28 adolescents) seen at either time point.Only the group difference in response inhibition remained significant in adolescence.

Mentions: As shown in Figure1, repeated measures ANOVAs of the ADHD subgroups revealed a significant main effect of time for response inhibition [F(1, 126) = 52.38, η2 = .29, p < .001], verbal working memory [F(1, 126) = 235.46, η2 = .65, p < .001], spatial working memory [F(1, 126) = 173.71, η2 = .58, p < .001], and response variability [F(1, 126) = 157.00, η2 = .55, p < .001]. There was a group trend for response variability [F(3, 126) = 2.42, η2 = .05, p = .07] but not for any other cognitive measure (ps > .10). In no instance was the time × group interaction significant (ps > .10).
