Altering Multitasking Behavior Using Low Current Brain Stimulation

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.

Treatment and study plan

Stimulation via noninvasive brain stimulation systems

Other

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.

Primary outcomes

  1. Response accuracy

    Time frame: 4 hours

    Measuring accuracy (correct vs. incorrect answers) of responses to stimuli while dividing attention and switching between tasks

  2. Response latency

    Time frame: 4 hours

    Measuring the amount of time (seconds) from when stimulus is presented to when participant answers prompt
