Circular organization of the instantaneous phase in ERPs and the ongoing EEG due to selective attention

It is known that signs of early auditory selective attention are reflected in the N1-wave of auditory late potentials. In recent years, we used instantaneous phase synchronization measures related to this N1-effect to assess the attentional effort in listening. In particular, we showed that listening effort induced by task difficulty can be quantified by using this method. Subsequently, in order to not be restricted to short transient stimuli in...
