How brains build higher order representations of uncertainty
Hojjat Azimi Asrari
Higher-order representations are neural or computational states that are “about” first-order representations, encoding information not about the external world per se but about the agent’s own representational processes – such as the reliability, source, or structure of a first-order representation. These higher-order representations appear critical to metacognition, learning, and even consciousness by some accounts, yet their dimensionality, construction, and neural substrates remain poorly und
