Studies of attention using the P1 and N1 waveforms indicate that both vision and audition involve an early-selection mechanism. These waveforms are components of the event-related potential (ERP) in the brain, and their modulation by attention suggests that the brain selects information to attend to early in the processing stream, rather than after the information has been fully processed.
