Basic episodic (top) and semantic (bottom) FOK paradigms. FOKs are made after a cued-recall attempt in both cases and are made on a “yes/no” or a Likert-scale. The recognition can be an “old/new” task or a multiple-alternative forced-choice. First-order performance is usually the proportion of correct recognition. Metacognitive sensitivity is assessed by comparing FOKs with memory performance in the recognition phase.
