This past year the proposed auditory-visual preceptuomotor paradigm was designed and implemented, and 12 twenty-one channel pilot recordings were conducted. The objective was to compare spatiotemporal brain-potential patterns associated with 1 the preparation to receive auditory or visual numeric stimuli, and 2 the processing of auditory and visual numeric stimuli. A bimodal paradigm sufficiently controlled for the application of a 49 channel Neurocognitive Pattern NCP Analysis has been finalized and participant screening sessions have begun. Sections III and IV of this Interim Progress Report are comprised of publihsed Science, 22097-99, 1983 and in preparation papers describing our recent visuospatial moveno-move study. The results of further signal processing studies on that data are described in Sections V and VI.
