The classification (FQnS and SPQnS) and misclassification indices (misFQnS and misSPQnS) as a function of noise threshold (η, panel a) and visual angle (δ, panel b). FQnS and SPQnS are plotted on the left y-axis and misFQnS and misSPQnS are plotted on the right y-axis. For the three experiments, η = 0.2 and δ = 3.0 were used in Equations 12 and 13
