The sensitivity of the [human] scalp-recorded, auditory evoked potential to selective attention was examined while subjects monitored 1 of 2 dichotically presented speech passages for content. Evoked potentials were elicited to irrelevent probe stimuli (vowel sounds) embedded in both the right and the left ear''s message. The amplitude of the evoked potential was larger to probe stimuli embedded in the attended message than to probe stimuli in the unattended message. Recall performance was unaffected by the presence of the probes. The hypothesis that this evoked potential sensitivity reflects an initial input selection stage of attention was supported.
