Pseudo-hyperscanning consists of the alignment of signals recorded from different brains at different times by using a physical signal common to the different recordings as a reference.

Sometimes the hyperscanning designs can be replaced by clever pseudo-hyperscanning set-ups. In the case of pseudo-hyperscanning designs using audio stimuli, combined EEG-auditory recording is a desirable feature since offline synchronisation is performed using the shared audio signal.
