‘Are you even listening?’ - EEG-based decoding of absolute auditory attention to natural speech
In this article, we perform absolute attention decoding to speech based on EEG signals, to determine whether a subject is attending to the speech or not.

What are we really decoding? Unveiling biases in EEG-based decoding of the spatial focus of auditory attention
In this article, we try to uncover potential biases of the CSP-based decoding of the spatial focus of auditory attention, using a multi-talker audiovisual EEG experiment.
