Claim One:
1. A method of testing subjects to characterize the subject's ability to inhibit sensory stimulation which comprises: (a) attaching electrodes to the subject's head and presenting the subject with primary meaningful sensory stimulus, (b) simultaneously superimposing secondary meaningless sensory stimuli on said primary sensory stimulus, (c) sensing the electrical brain responses of the subject, (d) presenting the subject with said secondary stimuli without said primary stimulus, (e) sensing the subject's electrical brain responses, (f) making a first comparison using a digital computer-based system of the responses evoked by said primary and secondary stimuli with the responses evoked by said secondary stimuli alone, and (g) making a second comparison using a digital computer-based system of said first comparison with a set of standard norms as an indication of the subject's ability to inhibit secondary stimuli.
