| Outline of Final Research Achievements |
In order to study on quantifying subjective evaluation by event-related potential (ERP), the ERP was measured when subjectively judging in opinion tests with pictures, such as foods, shirts with different colors, and animals. The ERP component P300, which is related to cognition and/or judgment, was detected, and its amplitude or area was discussed as a P300 parameter. In results, an evaluation task to detect the P300 corresponding to subjects’ preference was proposed. And it was cleared that the relationship between P300 area and the degree of the preference is not linear. As a fundamental study to use with the ERP, eye fixation and its time were measured when subjectively judging in opinion tests with paired food pictures. Results showed a feasibility of detecting a difference of subjective evaluation by the eye fixation time.
