Abstract : The purpose of this research was to study further the perceived brightness of flashing point sources near and above threshold. Most recent work has been with sources having too large a size to be considered point sources. A stimulus size of a few minutes was desired. The method of Katz and Sturr was employed, making use of a 200 msec flash as a standard and investigating shorter flashes using both the co-terminating and co-beginning methods of presentation.
