Description

Meta-d' is a signal detection theoretic measure of relative metacognitive accuracy, attributed in the article to Maniscalco and Lau (2012), that explicitly models the relation between primary task performance and metacognition. The article notes it "allows normalizing metacognitive performance with primary task performance", yielding a metacognitive "efficiency" measure (meta-d'/d') that is not inherently constrained by primary task performance or bias. The article presents it as an otherwise attractive measure whose general implication matches its own results: in certain tasks, resolution metrics are inherently related to performance.
