“…The Bayesian view provides a normative account for the updating process, indicating how, based on uncertainty, prior knowledge and new observations should be combined during learning. Optimal algorithms, such as the Kalman filter, developed by engineers in the 1960s form a foundation for modern accounts of learning in cognitive science and neuroscience (Bach and Dolan, 2012;Bland and Schaefer, 2012;Daunizeau et al, 2010;Mathys et al, 2011;Nassar et al, 2010;Payzan-LeNestour and Bossaerts, 2011;Preuschoff and Bossaerts, 2007). Essentially, the more confident we are in a new observation (e.g., because the stimulus is clear), the more this observation should impact our prior knowledge.…”
