Comparison of brain activity in success and failure in single and multitask game

Attention-Deficit/Hyperactivity Disorder (ADHD) is the disorder that occur to neurodevelopment with symptoms of hyperactivity, impulsivity, and/or inattention in childhood. In 2020, the U.S. Food and Drug Administration (FDA) per-mitted the game-based digital therapeutic device for ADHD children which name is 'EndeavorRx'. In this game, they used Go/NoGo task and tracking task as multitask. So, we constitute two types of single task and one multitask to compare between success and failure during single task and during multitask. We had two types of single task that are single task of Go/NoGo Task, single task of Target Tracking Task. In multitask, we did both of these tasks. We checked and compare Event Related Potential (ERP) of suc-cess and failure of Go/NoGo task in single task and multitask. We could see tendency of difference of ERP pattern between success and failure in single task. The ERP in single task results showed that the Go task had a delay in the positive peak time at the time of failure compared to the time at which it succeeded. This is thought to indicate that the response to the stimulus and the re-sponse were delayed, and it is thought that this was caused by the failure due to the delay in noticing or overlooking the color change. On the other hands, in success of Go task, we could see positive correlation of reaction time and P300 and N200 peak time. It can be considered that the individual difference in the speed of responding to the stimulus is likely to be smaller than the differ-ence in the speed of noticing the stimulus.
