Are judgments of learning made after correct responses during retrieval practice sensitive to lag and criterion level...

Although successful retrieval practice is beneficial for memory, various factors (e.g., lag and criterion level) moderate this benefit. Accordingly, the efficacy of retrieval practice depends on how students use retrieval practice during learning, which in turn depends on accurate metacognitive monitoring. The present experiments evaluated the extent to which judgments of learning (JOLs) made after correct responses are sensitive to factors (i.e., lag and criterion level) that moderate retrieval practice effects, as well as which cues influence JOLs under these conditions. Participants completed retrieval practice for word pairs with either short or long lags between practice trials until items were correctly recalled 1, 3, 6, or 9 times. After the criterion trial for an item, participants judged the likelihood of recalling that item on the final test 1 week later. JOLs showed correct directional sensitivity to criterion level, with both final test performance and JOLs increasing as criterion level increased. However, JOLs showed incorrect directional sensitivity to lag, with greater performance but lower JOLs for longer versus shorter lags. Additionally, results indicated that retrieval fluency and metacognitive beliefs about criterion level--but not lag--influenced JOLs.
