The purpose of this study is to examine whether Japanese junior high school pupils really dislike mathematics. In addition to questionnaires to inquire explicitly of the likings of school subjects, we administered the FUMIE Tests (Mori et al., 2008) to 512 junior high school pupils to assess the implicit evaluative association to the school subjects. We found a considerable proportion of pupils answered negatively to the target school subjects in the questionnaire while their implicit association scores showed somewhat positive valences. The discrepancies were larger for “mathematics” than “science”. One hundred of 512 pupils answered negatively to mathematics while their implicit measures were positive. In contrast, only five of 102 showed the same discrepancy for science. These results imply that there may exist a tendency to pretend to be a math-dislike in pupils. We discussed this tendency that may eventually lead them to real math-dislikes.
