| Hi Malcom and colleagues,
Thank you for opening this discussion about ear-EEG devices.
Have you perhaps encountered any system that can be potentially adapted to children and infants for auditory research? (i.e., due to smaller, differentiated anatomically ears - perhaps ways also to deal with spatial precision that is more messy in infants than in adults?).
Best, Efthymios

Hi Malcolm, We've put together a validation toolkit for ear-EEG
devices trying to help with this issue of evaluating the limits of the devices,
you can access it here ( https://osf.io/2dxs4/).
One component of the toolkit is a series of EEG paradigms that run on psychopy.
The detailed publication is here ( https://www.mdpi.com/1424-8220/24/4/1226).
ASSR and Alpha Block would be the simplest to figure out whether you are
getting anything useful or not. Kind regards Alejandro Hello Malcolm,
One idea could be to perform an ABR amplitude growth function as
commonly used in ENT clinics, see for example [1]. That would not
involve a test of the behavioural feedback part of your setup, but
verify the EEG recording signal chain. And it has the advantage that you
also gather a good characterization of the auditory system of the
participants which might prove useful in the analysis (individual
threshold, slope, latencies).
Greetings from a sunny Europe,
Stefan
