Abstract

The purpose of the current study was to determine whether the level of metacognitive sensitivity previously observed in global Judgments-of-Learning (JOLs) in temporal lobe epilepsy (TLE) patients could also be established when making item-by-item JOLs. Fourteen TLE patients and 14 control participants were compared on a memory task where 39 semantically unrelated word pairs were presented at three different levels of repetition. Thirteen word pairs were assigned to each level. A combined JOL and Feeling-of-Knowing (FOK) task was used to examine metamemory monitoring and control processes. The results showed that control participants outperformed TLE patients on recall and recognition. However, both groups were sensitive to repetition of the word pairs throughout the list, revealing intact online monitoring and control processes at encoding. These results are consistent with the findings of Howard et al. (2010) of intact metamemory in TLE patients and extend the findings of Andrés et al. (2010) of metamemory sensitivity from the global level to the item-by-item level. Finally, the current findings provide additional evidence of a dissociation between memory and metamemory in TLE patients. (JINS, 2013, 19, 1–10)
