Altering Multitasking Behavior Using Low Current Brain Stimulation

Not Applicable

Active, not recruiting

• Conditions: Cognitive Change
• Interventions: Other: Stimulation via noninvasive brain stimulation systems

• Registration Number: NCT03873636
• Lead Sponsor: Tufts University

Brief Summary

This study is designed to investigate multitasking deficits, with a particular interest in reducing costs related to dual-tasking (dividing attention between tasks) and task-switching (switching between tasks) using noninvasive brain stimulation.
