Thomas O. Nelson contributed to cognitive psychology through work on metacognition and the accuracy of judgments of learning. With John Dunlosky, he studied how the delay before a judgment and the information available at judgment affect prediction of later remembering. Separating prediction from subsequent recall allows researchers to test which cues support useful monitoring, rather than equating high predicted success with good human memory. [ref]
