Simplified Bayesian model. (A) Sensory weights in the simplified Bayesian model (average of 20000 trials) as a function of time after stimulus presentation. Black line: c = 2. Light gray line: c = 0 (i.e., sensory input is pure noise). Dark gray line: c = 1. (B) Average log odds Lt (plain lines) and decision threshold (dashed lines) in the simplified Bayesian model. These temporal profiles were obtained by averaging over 20000 trials. The decision variables and threshold on individual trials (as well as the sensory weights) are varying randomly due to sensory noise (e.g., see Figure 1A). Black lines: c = 2 Dark gray lines: c = 1. Light gray lines: c = 0.2.
