Diffusive and Specific Searches on Eye Fixation in Opinion Test with Paired Food Pictures by Stimulus-Comparison

Abstract

In the subjective selection test with paired food pictures for each opinion 'Like' and 'Dislike', the frequency of eye fixation for 'selected' pictures was higher than that for 'not selected' in the specific search. In this study, the diffusive and specific searches were obtained from eye fixation data in the subjective evaluation test by the stimulus-comparison method with opinions 'Like', 'Same', and 'Dislike', in which paired food pictures were displayed; left side is for reference, and right side is for evaluation. Results show no significant difference between the reference and the evaluated pictures in the specific search, which indicates to differ from the case of the selection test.
