Judgments of learning: evidence for a two-stage process.
Three experiments tested the hypothesis that people make judgments of learning (JOLs) by attempting to retrieve the target first. If this were the whole story, then the reaction time (RT) functions for making JOLs with no special instructions would parallel those found when people are told to first attempt retrieval and then make a JOL. In the present data, monotonic functions, showing an increase in RT with decreasing JOL, were found when people were instructed to retrieve covertly or overtly and then make a JOL, as would be expected if retrieval fluency entirely determined JOLs. However, the functions for making uninstructed JOLs were different: Low JOLs were made quickly, not slowly, and the curves were inverted U shapes, rather than linear. Furthermore, people's memory performance was somewhat better, especially on low-JOL items, when they were instructed to first retrieve as opposed to when they were told only to make JOLs. To account for these data, we propose a two-stage model of JOLs, with the first stage occurring prior to attempted retrieval.
