Figure Legend:
Various decision criteria. (a) The best fit model (k T, k F, γ, α = 0) assuming that the subject only chooses a single fixed
decision criterion for all stimuli (α = 0, see Equation 7). The blue vertical line indicates the results of a pure change in
target contrast. Other black lines indicate the influence of target contrast when the flanker contrast is higher. The red
curve represents a change in the flanker contrast for a target contrast of 1. Other black curves represent pure changes in
flanker contrast if the target contrast is lower. If the data perfectly fit the model, the intersections of the lines would match
the observed data. Blue crosses from Figure 1a would fall on the blue line, and red crosses from Figure 2b would fall on
