Study Summary
The goal is to replicate in-lab results from transcranial alternating current stimulation (tACS) with at-home tACS.
Primary Outcome
Assessment of multitasking ability using change from baseline scores in d' cost (metric of discriminability). Discrimination performance (d') was measured for each participant by comparing hit (correct responses to target signs) rates and false alarm (responses to non-targets) rates and calculated as d' = Z (hits) - Z (false alarms). d' cost was then calculated as the ratio of d' during single task target discrimination task to multitask target discrimination, expressed as percentage cost.
