Semi-analytical approximations to statistical moments of sigmoid and softmax mappings of normal variables (2017, background): “Note that, in the context of our own work, approximations of this sort have already found their way in many probabilistic models of learning and decision making (Daunizeau et al., 2010; Devaine et al., 2014; Lebreton et al., 2015; Mathys et al., 2011).”
Self-Evaluation of Decision-Making: A General Bayesian Framework for Metacognitive Computation (2017, background): “Akin to perceptual categories, choice values are not perfectly known to the subject, but are probabilistic (De Martino et al., 2013; Lebreton et al., 2015; McFadden, 1980).”
Explicit representation of confidence informs future value-based decisions (2016, background): “(5) Participant choices did not correspond to their BDM ratings (when predicting choices from differences in value, the DV coefficient deviated by more than 2 standard deviations (s.”
