Abstract:

The second of two reports is presented whose goal is to evolve methodology for use in evaluating the visual evoked response VER. The first presented techniques for obtaining and evaluating the complete evoked response in this study, the method purposely results in VERs which are incomplete, by presenting the visual stimuli at rates that are too rapid to be responded to singly. Rapid flash rates are shown to produce VERs which are reliable and easy to interpret and assess statistically. Furthermore, they appear to be composed of factors in addition to elements from the complete evoked response. Together the methods evolved in the two papers provide efficient techniques for using the VER as a tool in studying Naval problems.
