Cognitive Studies, 23(2), 135-152. (June 2016) In reading, we are often engaged to the book, lose our self-awareness, transport ourselves into the narrative world, and have deep empathy for the characters in the books. These absorption phenomena have been characterized and classified based on reader s introspective report using the questionnaires. However this methodology relying on introspective reports alone may not be accurately enough to study the absorption: the readers in the absorption cannot reliably report their experiences, as they lose their self-awareness to some degree by definition. This motivates this study to build an alternative measures of absorption, which we can evaluate its reliability by its consistency across multiple subjective and objective measures of reader s states. We conducted two experiments by employing the first author as a subject in a natural and reader friendly situation. In the first experiment, we analyzed the cross correlation between reader s absorption ratings and statistics, CVR-R and fractal dimension, estimated from reader s heart rates. In the second experiment, we analyzed the relationship between reader s absorption ratings and bodily movements using the classification tree technique. The results of these two experiments suggest that the CVR-R and the fractal dimension estimated from heart rates, and the bodily movement can be used as alternative measures indicating the level of reader s absorption.
