A Performance Study of the Wavelet-Phase Stability in the Quantification of Neural Correlates of Auditory Selective Attention

Large–scale neural correlates of auditory selective attention reflected in the electroencephalogram (EEG) have been identified by using the complex wavelet–phase stability measure (WPS). In this paper, we study the feasibility of using the WPS in extracting the correlates of selective attention by...
