In this study, we investigated the relationship between depressive tendency and relative accuracy of metacomprehension. Many previous studies have focused on negative confidence bias or absolute accuracy of depressive persons (e.g., Fu et al., 2012). However, it has not been examined how depressive tendency affects relative accuracy. In experiment, participants read four expository texts. After reading, participants assigned a comprehension rating to each text and then completed a comprehension test. Finally, participants completed the Beck Depression Inventory (BDI) of Japanese, originally developed by Beck et al (1961). The result showed that there was negative correlation between the score of BDI and relative metacomprehension accuracy. Given that the high score of BDI means serious depressive, this result suggested that depressived persons cannot discriminate the degree of comprehension level between a numbers of texts.
