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.

Outcome Measures
Primary Outcomes (2)
Response accuracy
Measuring accuracy (correct vs. incorrect answers) of responses to stimuli while dividing attention and switching between tasks
4 hours
Response latency
Measuring the amount of time (seconds) from when stimulus is presented to when participant answers prompt
4 hours
Study Arms (2)
Active Stimulation
EXPERIMENTALActive stimulation of targeted brain regions involved in task-switching and dual-tasking.
Sham Stimulation
SHAM COMPARATORSham stimulation of targeted brain regions involved in task-switching and dual-tasking.
Interventions
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.
