Figure 4. Results from Experiment 2 Averaged Over Five Observers.

Figure 4

(A,B) Yes rates under colinear and orthogonal context (schematically like Figure 2A), respectively. The curves are the Bayesian fits. The four Bayesian parameters (and their 95% confidence intervals) are k = 3.8 (1.8, 5.8), σn = 0.0027 (0.0021, 0.0033), P(yes)colinear = 0.982 (0.974, 0.989), and P(yes)orthogonal = 0.88 (0.85, 0.92), giving a fitting quality of RMSNFE = 1.0.

(C,D) Yes rates under different contextual contrast Cc = 0.01 and Cc = 0.4, respectively, together with those under no context. For colinear context CFI = 0.23 ± 0.05 and −0.18 ± 0.15 for Cc = 0.01 and 0.4, respectively; for orthogonal context CFI = −0.018 ± 0.06 and −0.46 ± 0.055 for Cc = 0.01 and 0.4, respectively.

(E) Prior P(yes) for the two contextual configurations. The error bars denote SEMs in (A–D), and 95% confidence intervals in (E).
