Summary

This trial aims to investigate how practicing multitasking affects the brain. Participants will learn and practice two tasks, either separately or together, over several days. The researchers will use brain imaging and behavioral tests to

Who is the study for?
This trial is for individuals with ADHD, healthy subjects interested in executive function, and those who can perform tasks based on different rules. Participants will be trained to multitask or single-task over multiple days.Check my eligibility
What is being tested?
The study tests how practicing multitasking versus single tasks affects the brain's task management. It measures changes in behavior and brain activity using psychological tests and fMRI before and after practice sessions.See study design
What are the potential side effects?
Since this is a behavioral trial involving practice of cognitive tasks without medical interventions, there are no direct side effects like those seen with medications; however, participants may experience fatigue or stress.
