Conditions
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.
Interventions
OTHERStimulation via noninvasive brain stimulation systems
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.

Design outcomes
Primary
| Measure | Time frame | Description |
