Abstract	Using the Wavelet Transform (WT), a time frequency representation, we studied responses to auditory stimulation in the ‘alpha’ range (8Hz–13Hz) in the low and high education groups. Auditory evoked responses of total 16 healthy subjects (8 in each group, low and high education groups) were studied with 2 different auditory stimuli (standard and target stimuli). Upon the stimulus types, event-related responses in the 8Hz–13Hz (‘alpha’) range were distributed mainly in the central (Fz, Cz and Pz) locations. The Low education group had significantly high alpha power at Fz and Cz locations comparing the High education group in the case of standard stimuli, where as remarkable increased alpha power was found in the same group in the case of target stimuli at Pz area. We concluded that the distributed origin of event-related alpha oscillations has the relationship with educational experience.
