INCREMENT THRESHOLDS ON BLACK BARS.

Abstract

Under conditions that isolate rod vision, increment thresholds were measured on black bars of various widths, and compared to the increment threshold measured on a homogeneously illuminated field without the bar. Thresholds were found to be elevated in the presence of bars in the vicinity of 10 feet of arc wide. However, this effect does not occur when the retinal images of adapting and test fields are stabilized. (Author)
