<Hakwan Lau> studies awareness and <metacognition>. With <Brian Maniscalco>, he developed a <signal detection theory> approach for estimating <metacognitive sensitivity> from confidence ratings. The resulting <meta-d-prime> expresses confidence-based <discrimination> using a scale comparable to task sensitivity. The method separates how strongly confidence tracks correctness from a general tendency to use high or low confidence, while retaining assumptions about the modeled decision process. <A signal detection theoretic approach for estimating metacognitive sensitivity from confidence ratings by Brian Maniscalco and Hakwan Lau>[2012, meta-d-prime construction and confidence criteria]{ref}
