Filling-In and Suppression of Visual Perception from Context: A Bayesian Account of Perceptual Biases by Contextual Influences
Figure 6
Fit to Data in Experiment 3 by the Bayesian Model
(A–C) The red, magenta, and blue curves and data points indicate respective quantities associated with different contextual contrasts Cc = 0.01, 0.05, and 0.4, respectively. The fitted Bayesian parameters (and their 95% confidential intervals) are k = 3.91 (1.95, 5.87), σn = 1.60 × 10−3 (1.45 × 10−3, 1.73 × 10−3), and P(yes) = 0.97 (0.96, 0.98) for the 2-sided, P(yes) = 0.87 (0.83, 0.91) for the 1-sided, and P(yes) = 0.92 (0.89, 0.95) for the sparse context. RMSNFE = 1.07.
(D) The prior P(yes) for the three different contextual configurations. The error bars denote SEMs in (A–C), and 95% confidence intervals in (D).
