A Bayesian Attractor Model for Perceptual Decision Making
Fig 11
Confidence in relation to stimulus strength as predicted by the BAttM for the experiment of [54].
These confidence values result from continuing accumulation of evidence for 100ms after the internal threshold was crossed but before a corresponding motor response was completed (cf. [35]). Negative coherences: left motion stimulus, positive coherences: right motion stimulus. For each coherence level we simulated 2,500 trials (5,000 for 0% coherence) using the BAttM. Shown are mean confidence values and their standard errors. Parameters were those listed in Table 2 with q = 0.5.
