The effects of cravings on metacognition

This study used a sample (N = 68) of regular coffee drinkers to investigate how cravings may influence JOLs when completing a cue-only word pair task. Two groups: a craving and a control group were randomly allocated where cravers had to avoid consuming coffee before testing. Both groups completed a word pair encoding task followed by completing either a craving induction task if they had abstained from coffee or a control task if they had not. Both groups then made cue-only JOLs and a subsequent retrieval attempt on the target. Craving strength was measured at the end of the experiment. Results indicated that JOLs for cravers were less realistic which may have been due to the presence of cravings.
