Reaction Time as a Function of Onset and Offset Stimulation of the Fovea and Periphery

Abstract
Reaction times were obtained for the onset and offset of luminous stimuli of 31,400 mL., 314 mL., 3.14 mL., and 1.98 mL., presented in the fovea and periphery. It was found that in the periphery offset RTs are longer than onset RTs. The opposite is true for the fovea. In both the fovea and periphery the differences between the onset and offset RTs decrease as the luminance increases.
