Experiment 2: Parameters fitted per condition in a descriptive model that assumes that responses follow a mixture of a von Mises distribution centered at the target orientation, a uniform distribution reflecting guesses, and von Mises distributions centered at the distractor orientations. (A) Concentration parameter of the von Mises distribution. (B) Weight to the uniform distribution. (C) Weight to nontarget responses. The same caveat as in Figure 21C applies.
