Objective: Conflict monitoring is well known to be modulated by context. This is known as the Gratton effect, meaning that the degree of interference is smaller when a stimulus–response conflict had been encountered previously. It is unclear to what extent these processes are changed in ADHD.
Method: Children with ADHD (combined subtype) and healthy controls performed a modified version of the sequence flanker task.
Results: Patients with ADHD made significantly more errors than healthy controls, indicating general performance deficits. However, there were no differences regarding reaction times, indicating an intact Gratton effect in ADHD. These results were supported by Bayesian statistics.
Conclusion: The results suggest that the ability to take contextual information into account during conflict monitoring is preserved in patients with ADHD despite this disorder being associated with changes in executive control functions overall. These findings are discussed in light of different theoretical accounts on contextual modulations of conflict monitoring. (J. of Att. Dis. 2020; 24(11) 1503-1510)
