A. (Top) Energy landscape for different BSIfb ratios. The BSI strength is set to be 0.857. If we increase the BSIfb ratio, the slope of the landscape becomes shallower while the crater on top of the hill becomes bigger and deeper. (Bottom) Energy landscape for different BSI strengths. The BSIfb ratio is set to be 0.848. A similar trend can be observed if we increased the BSI strength. B. The differences between the heights of the two walls of the crater (H) as a function of BSIfb ratio and strength. C. Performance as a function of H plotted for several BSIfb ratios and strengths. Each color indicates data obtained from one BSIfb ratio and each dot of a given color represents a specific BSIfb strength for the corresponding BSIfb ratio. The data from different BSIfb ratios form a linear relationship with H with overlapping distributions, which indicate that the performance is mainly determined by the size of the crater. Regardless a specific combination of BSIfb ratio and strength, as long as they give rise to the same H, the performance of decision is the same. The stimulus motion strength c’ = 3.2% in all panels.
