Altering Multitasking Behavior Using Low Current Brain Stimulation

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Active Stimulation<br>Active stimulation of targeted brain regions involved in task-switching and dual-tasking. | Other: Stimulation via noninvasive brain stimulation systems<br>* Active (at or below 2mA) stimulation targeting brain regions engaged in task-switching and dual-tasking for 30-40 minutes. Local IRB has determined the Soterix, Neuroelectrics, & Halo devices to be non-significant risk (NSR) devices via abbreviated investigational device exemption (IDE) procedure.<br>|
| Sham Comparator: Sham Stimulation<br>Sham stimulation of targeted brain regions involved in task-switching and dual-tasking. | Other: Stimulation via noninvasive brain stimulation systems<br>* Active (at or below 2mA) stimulation targeting brain regions engaged in task-switching and dual-tasking for 30-40 minutes. Local IRB has determined the Soterix, Neuroelectrics, & Halo devices to be non-significant risk (NSR) devices via abbreviated investigational device exemption (IDE) procedure.<br>|
