Measurement of the distance between recognition categories by interference experiment

In the case of doing two things at the same time, if each task uses the same modality (e.g. visual sense) then they interfere with each other, but if each uses a different one (e.g. visual sense and auditory sense) then they don´t interfere. We noticed interference between same-modality tasks in this study, and we examined whether there was any strength or weakness of the interference in each cerebral recognition category (figures, languages, faces) in experiments where selective interference occurred when carrying out two visual trials at the same time (dual-task method). Furthermore, we also measured the cognitive distance between each recognition category. From the results, we found that interference is strong in the face category, the distance of facial cognition is close to that of both figures and languages, and the facial cognitive position exists in the middle of the other two categories
