In Experiment 1 of Arnold et al., (2008), a white noise pattern and a target image switched between both eyes at selected constant rates. To test for optimal rates of BSS, images were switched between the both eyes at speeds ranging from 0.5 - 15 Hertz and the degree of suppression was measured. Participants were asked to indicate their response when they detect any part of the target image. Results showed that the optimal switch rates for BSS was of 1 Hertz and this is the rate which suppression was the longest.
