Advantages of remote data collection.

Limitation	Potential contribution of remote data collection
Small sample size	Improve scalability using remote research to achieve larger N.
Limited cognitive domains studied	Include testing of multiple cognitive domains in study protocols (using short forms and/or multiple assessments).
Parameter space refinement	Ease of collecting larger or repeated samples enables testing multiple protocol or stimulation types (e.g., tragus vs. concha).
Generalizability	Removing geographical and financial hurdles for participants can lead to more representative samples.
Lack of longitudinal studies	To establish causal evidence, test participants at multiple time points without the burden of in-person research appointments.
