Abstract
Electromyo-graphic potentials were recorded at the forehead, chin, right and left forearm extensors, and EEG recorded from bilateral frontal and parietal placements, as the same recorded detective story was presented three times. Forehead EMG''s, which were more closely related to listening than those of chin or forearm, appeared at least partly determined by interest in the material, and were considered as indicative of motivation to listen. On only the first hearing EMG gradients were inversely related to EEG amplitude. Separate cue and arousal functions were postulated.Keywords
