Failure to find the ¿local¿ EEG OR to low-level auditory stimulation

Journal Article


Abstract


  • Sokolov’s dichotomization of the EEG OR into “local” and “general” on the basis of differential habituation rates was investigated with special reference to the auditory EEG OR. The magnitude of alpha desynchronization at stimulus onset was examined in the auditory, visual, and motor projection areas as a function of stimulus intensity and stimulus repetition. Significant intensity and repetition effects were found as required for any OR indicator, but these did not vary with recording site. Thus no evidence for the existence of a “local” auditory EEG OR was found in the present study. © 1976, Psychonomic Society, Inc.. All rights reserved.
