Figure Legend:
Replicability of human responses for different nonlinear models. (A) Linear-human consistency (percentage of trials on
which the linear first-order model and the human observer gave the same response to the same set of stimuli) is plotted
on the x axis for luminance kernels against model-human consistency for seven different nonlinear models. Red and
light-red symbols refer to models that incorporate second-order kernels, blue and light-blue symbols refer to variants of
the uncertainty model (see Materials and methods). Solid red symbols refer to the full nonlinear second-order model;
light-red symbols refer to the same model when regions outside the diagonal of the second-order kernels are set to 0,
