Abstract(in English) To determine the performance of estimating the degree of "strength of belief" (SOB) of responses using eye-movements, the features of eye-movements were extracted while subjects answered questions and reviewed their own responses to multiple choice tasks. All fixation points of eye-movements were classified into visual areas, or cells, which corresponded with the positions of questions. The high and low SOBs for the answers were defined according to each subject's declaration of certainty. The estimation was conducted using Support Vector Machines (SVM) with features of eye-movements between two successive fixations. In the results, the overall estimation performances were significant when the prediction was calculated using certain combinations of features for answering and reviewing sessions respectively. In comparing feature combinations of eye-movements for significant estimations between answering and reviewing sessions, significant combinations components of features between the two sessions did not coincide. As some features between the two sessions were significantly different, the SOB estimation procedure depends on the viewing mode, such as answering or reviewing.
